2026 Section 179 + Bonus Depreciation: $2.56M Expensing Cap + 100% Bonus Made Permanent
What changed for 2026 under OBBBA
Two things changed for 2026 and both are large. First, the Section 179 expensing limit jumped from $1,250,000 (2025) to $2,560,000 (2026), with the investment-based phaseout starting at $4,090,000 of total qualified property placed in service during the year. The phaseout is dollar-for-dollar above the $4.09M threshold, so a business that places $5,090,000 of qualifying property in service in 2026 loses $1,000,000 of the §179 deduction and is capped at $1,560,000 of §179 expensing. Above $6,650,000 of placed-in-service property, the §179 deduction is fully phased out and the business uses bonus depreciation or regular MACRS instead.
Second, 100% bonus depreciation under §168(k) was revived and made permanent. The phasedown that started in 2023 (80%), continued in 2024 (60%) and 2025 (40%), and was scheduled to land at 0% in 2027 is gone. Property placed in service in 2026 and going forward gets 100% bonus depreciation if it qualifies, with no scheduled sunset. This is the single most important business tax change in OBBBA for businesses that buy equipment, vehicles, machinery, or qualified improvement property.
The combination of a $2.56M §179 cap and permanent 100% bonus depreciation means that almost every equipment purchase a small or mid-size business makes in 2026 can be fully deducted in the year of purchase, subject to two specific limitations. Section 179 is capped at taxable business income, so a business with a net operating loss cannot use §179 to push the loss deeper. Bonus depreciation has no taxable income limitation and can be used to create or expand a net operating loss. That single difference drives most of the strategy questions about which deduction to use on a given asset.
OBBBA also retained Section 179 indexing for inflation, so the $2.56M cap will continue to climb in future years. The cap is statutory in §179(b)(1) and the phaseout threshold in §179(b)(2), both indexed under §179(b)(6). The IRS announces the inflation-adjusted figures each fall for the following tax year (the 2026 numbers were announced in Rev. Proc. 2025-32 from the IRS). Businesses planning multi-year equipment purchases should expect the §179 cap to drift higher with inflation, while the bonus depreciation rate is now locked at 100% indefinitely under §168(k) as amended.
Section 179 mechanics — the $2.56M and $4.09M numbers
Section 179 lets a business immediately deduct the cost of qualifying tangible personal property placed in service during the year, instead of capitalizing the cost and recovering it through depreciation over the asset’s MACRS recovery period. The 2026 §179 cap is $2,560,000 of deduction per taxpayer per year. The phaseout begins when total qualifying property placed in service during the year exceeds $4,090,000, and the §179 cap is reduced dollar-for-dollar above that threshold.
Eligible property under §179(d) includes tangible personal property used in a trade or business: machinery, equipment, computers, office furniture, vehicles (with the heavy SUV cap discussed below), certain qualified real property improvements (roofs, HVAC, fire protection, security systems on nonresidential real property), and off-the-shelf computer software. Real property itself (buildings, land) is not §179-eligible. The property must be used more than 50% for business to qualify, and §179 is elective on an asset-by-asset basis, meaning a business can choose which assets to expense under §179 and which to depreciate normally or under bonus.
The taxable income limitation under §179(b)(3) caps the §179 deduction at the business’s net taxable income from active trades and businesses, computed without regard to the §179 deduction itself. A business with $1,500,000 of taxable income before §179 can only take $1,500,000 of §179 expense even if it placed $2,000,000 of qualifying property in service. The unused $500,000 carries forward indefinitely to future years and gets deducted when the business has sufficient taxable income to absorb it. The carryforward is tracked on Form 4562 and on the business’s books.
Real-world example: a manufacturing S-corp places $1,800,000 of new equipment in service in 2026. The business has $2,100,000 of taxable income before any §179 election. The business elects §179 on the full $1,800,000. The deduction reduces taxable income to $300,000. The full $1,800,000 is deducted in 2026 with no carryforward. If the same business had only $1,200,000 of taxable income before §179, the deduction would be capped at $1,200,000 and $600,000 would carry forward to 2027. The carried-forward §179 is treated as a 2026 election but the deduction lands in 2027 when income absorbs it.
The phaseout under §179(b)(2) is the other key limitation. A business that places $5,000,000 of qualifying property in service in 2026 (above the $4.09M threshold by $910,000) has its §179 cap reduced by $910,000, from $2,560,000 down to $1,650,000. A business that places $6,650,000 of qualifying property in service is fully phased out of §179 and gets no §179 deduction at all. The phaseout is a cliff for large equipment purchasers, but bonus depreciation has no comparable cap, so the loss of §179 is mostly cosmetic for businesses that can use bonus instead.
100% bonus depreciation made permanent
Bonus depreciation under §168(k) lets a business deduct a percentage of the cost of qualifying property in the year of placement, with the remainder depreciated under regular MACRS. The bonus percentage was 100% from 2017 through 2022, then phased down to 80% (2023), 60% (2024), 40% (2025), and was scheduled to hit 20% in 2026 and 0% in 2027. OBBBA changed all of that. Bonus depreciation is back to 100% for 2026 and is now permanent at 100% with no scheduled sunset.
Qualifying property under §168(k) is broader than §179 in some ways and narrower in others. The property must have a MACRS recovery period of 20 years or less, which covers nearly all tangible personal property and qualified improvement property. Like §179, real property itself (buildings) doesn’t qualify, but improvements to the interior of nonresidential real property (qualified improvement property under §168(e)(6)) do qualify if placed in service after the building was first placed in service. New and used property both qualify under §168(k) as amended, as long as the property was not used by the taxpayer or a related party before acquisition.
The key difference from §179: bonus depreciation has no business income limitation. A business with a net operating loss can take bonus depreciation and push the NOL deeper. The NOL carries forward under §172 and gets absorbed against future taxable income (subject to the 80% taxable income limitation on post-2017 NOLs). For a business in startup mode or in a heavy investment year, bonus depreciation is the lever that creates a deductible loss now and matches the deduction against future profitable years.
Bonus depreciation is automatic on qualifying property unless the taxpayer elects out under §168(k)(7). The election out is made on a class-by-class basis (for example, electing out for all 5-year MACRS property but not for 7-year MACRS property). The election is irrevocable without IRS consent and is made on a timely-filed return for the year the property is placed in service. Most businesses don’t elect out because the cash-flow benefit of immediate expensing outweighs any reason to spread the deduction across the MACRS recovery period.
Real-world example: a restaurant places $400,000 of kitchen equipment, $150,000 of qualified improvement property (new flooring and lighting), and a $90,000 commercial vehicle in service in 2026. Total $640,000 of qualifying property. Under §168(k) with 100% bonus depreciation, the full $640,000 is deductible in 2026 regardless of the restaurant’s taxable income. If the restaurant has a $400,000 operating loss for the year before depreciation, the bonus depreciation produces a $1,040,000 NOL that carries forward to offset future income. Section 179 wouldn’t have produced this result because the §179 deduction would have been capped at the (negative) business income.
Section 179 versus bonus depreciation — when to use which
Both rules produce 100% immediate expensing on qualifying property in 2026, so why have both? The answer is that §179 and bonus depreciation have different mechanics, different limits, and different recapture rules, and a smart strategy uses both in the right sequence. The general rule: use Section 179 first for control over which assets get expensed, then apply 100% bonus depreciation to whatever §179 doesn’t cover.
Section 179 is elective and asset-specific. A business can choose to §179 a specific piece of equipment and not others. This matters when the business wants to preserve depreciation for future years on certain assets (for income smoothing) or wants to avoid the §179 recapture trap (discussed below) on assets likely to be sold or converted to personal use within the recovery period. The election is made on Form 4562 by listing the specific assets and the §179 amount for each.
Bonus depreciation is automatic and class-based. The taxpayer either takes bonus on all property in a given MACRS class for the year or elects out for that class. The taxpayer cannot bonus depreciate one 5-year asset and not another in the same year — it’s all or none within the class. This makes bonus a blunter tool than §179 but a more thorough one.
The taxable income limit on §179 is the big differentiator. A business with sufficient taxable income can use §179 freely. A business with low or negative taxable income should rely on bonus depreciation, which has no income limitation. For most operating businesses in a profitable year, §179 and bonus produce identical first-year results. For loss-year businesses, only bonus produces the result.
The standard play looks like this. Step one: identify all qualifying property placed in service during the year. Step two: elect §179 on assets where the business wants the flexibility to control the timing of the deduction (for example, on assets the business might sell within the recovery period, where §179 recapture is more favorable than bonus recapture in some scenarios). Step three: take 100% bonus depreciation on everything else. Step four: confirm that total deductions don’t push the business into an unintended NOL position or unintended pass-through loss limitation issue.
One scenario where §179 wins outright: a small business with a single major equipment purchase that would phase out bonus depreciation eligibility if used on related-party transactions. Bonus depreciation requires that the property was not used by the taxpayer or a related party before acquisition. Section 179 has no such restriction. A business buying used equipment from a related party should use §179, not bonus.
One scenario where bonus depreciation wins outright: a business with a large equipment purchase year exceeding the §179 phaseout. A construction company that places $7,000,000 of qualifying equipment in service in 2026 is fully phased out of §179 (the cap drops to zero at $6,650,000 of placed-in-service property). The full $7,000,000 deduction comes through bonus depreciation alone. Section 179 is not available at that purchase level.
Heavy SUV cap — the $32,000 separate limit
Vehicles weighing more than 6,000 pounds gross vehicle weight rating (GVWR) but not more than 14,000 pounds are subject to a separate §179 cap of $32,000 for 2026. This is the so-called heavy SUV cap under §179(b)(5). It applies to most SUVs and pickup trucks in the 6,000 to 14,000 pound GVWR range, including popular models like the Ford Expedition, Chevrolet Tahoe, Cadillac Escalade, GMC Yukon, and full-size pickups like the Ford F-250 and F-350.
The $32,000 cap is separate from and additional to the $2.56M general §179 cap. A business can §179 up to $32,000 on a heavy SUV in 2026 and then use the remaining §179 capacity on other equipment up to the $2.56M overall cap. The heavy SUV cap exists to prevent the §179 deduction from being used to fully expense luxury vehicles, which Congress was concerned about in the post-2002 rule rewrites.
Bonus depreciation under §168(k) is not subject to the heavy SUV cap. A business that buys a $90,000 heavy SUV in 2026 and uses it 100% for business can §179 $32,000 of the cost and bonus depreciate the remaining $58,000 under §168(k), achieving full first-year expensing. The combination of §179 (up to $32,000) plus 100% bonus on the remainder is the standard play for heavy SUV purchases in 2026.
Vehicles weighing 14,000 pounds or more GVWR are not subject to any §179 vehicle cap. The full §179 deduction applies up to the $2.56M overall cap, with no per-vehicle limit. Heavy duty pickups, dump trucks, semi tractors, and similar commercial vehicles fall in this category. A construction company can §179 the full cost of a $200,000 dump truck in 2026 without hitting any vehicle-specific cap.
Vehicles weighing less than 6,000 pounds GVWR (passenger automobiles under §280F) are subject to the luxury auto depreciation limits under §280F(a). The 2026 limits cap first-year depreciation at $20,400 for passenger autos (including bonus depreciation), $20,400 for trucks and vans, and similar limits in subsequent years. The §280F caps are much lower than the heavy SUV $32,000 and severely limit the §179/bonus benefit on most passenger cars. A business buying a $70,000 luxury sedan is limited to $20,400 of first-year depreciation regardless of §179 or bonus elections.
Real-world example: a real estate brokerage buys a $95,000 Cadillac Escalade in 2026 with 6,800 lbs GVWR (heavy SUV class), used 100% for business. The owner can §179 $32,000 of the cost and take 100% bonus depreciation on the remaining $63,000, producing a $95,000 first-year deduction. Without bonus depreciation, the §179 deduction would have been capped at $32,000 with the remaining $63,000 depreciated over five years under MACRS. With bonus, the full $95,000 is deducted in 2026. The OBBBA permanent extension of 100% bonus is what makes this work.
The 50% business use requirement applies to both §179 and bonus depreciation on vehicles. A vehicle used less than 50% for business loses the §179/bonus eligibility entirely and is depreciated under straight-line method over the §280F recovery period. The business-use percentage is recalculated annually, and if business use drops below 50% in a later year, prior-year §179 and bonus depreciation can be recaptured as ordinary income. Vehicles used for personal commuting in addition to business travel need careful tracking of mileage to support the business-use percentage.
Vehicle and equipment timing strategy
Timing matters because the §179 deduction and the bonus depreciation deduction both attach to the year the property is placed in service, not the year of purchase. A business that orders equipment in December 2025 but doesn’t receive and place it in service until January 2026 deducts the cost under the 2026 rules ($2.56M §179 cap, 100% bonus). A business that receives the same equipment in December 2025 and places it in service that month deducts under the 2025 rules ($1.25M §179 cap, 40% bonus).
Placed in service means the property is ready and available for its specifically assigned use in the business. Equipment sitting in inventory waiting to be installed is not placed in service. Equipment installed and ready for use, even if not yet actively producing revenue, is placed in service. The IRS interprets placed in service broadly in favor of taxpayers, but the documentation needs to support the placed-in-service date if challenged.
For 2026, the planning is straightforward: place qualifying property in service before December 31, 2026 to capture the 100% bonus depreciation and full §179 cap. Property placed in service after December 31, 2026 will be subject to whatever 2027 rules apply (still 100% bonus, $2.56M §179 cap adjusted for inflation). The big difference is between 2025 and 2026, where the cap doubled and bonus jumped from 40% to 100%. Businesses sitting on the fence about an equipment purchase at year-end 2025 should consider deferring placement to January 2026 to capture the better treatment.
Year-end equipment purchases create a half-year convention issue under §168(d). Property placed in service in the last quarter of the year may trigger the mid-quarter convention if it exceeds 40% of total property placed in service during the year. The mid-quarter convention reduces the first-year MACRS depreciation on all property placed in service that year, but it does not affect §179 or bonus depreciation, which are taken at 100% regardless of placement timing within the year. The convention is mostly relevant for businesses electing out of bonus on some property classes.
Real-world planning example: a small manufacturer is considering a $1,200,000 equipment upgrade in late 2025. Under 2025 rules, §179 covers $1,200,000 (under the $1.25M cap) and the deduction is immediate. Under 2026 rules, §179 covers the same $1,200,000 (well under the $2.56M cap) and the deduction is also immediate. For this business, the timing doesn’t matter much. But consider a different scenario: the same business is considering a $1,800,000 upgrade. Under 2025 rules, only $1,250,000 of §179 is available, with the remaining $550,000 subject to 40% bonus depreciation ($220,000 in year one) and the balance depreciated under MACRS. Under 2026 rules, the full $1,800,000 is expensed in year one via §179 ($1,800,000 within the $2.56M cap). The 2026 placement saves the business roughly $130,000 in year-one tax (at a 21% federal rate, plus state).
Section 179 carryforwards add another timing wrinkle. A §179 deduction limited by taxable income in the year of placement carries forward to future years. A 2026 §179 election that exceeds the business’s 2026 taxable income produces a carryforward that gets used in 2027 or later. The carryforward retains its character as a §179 deduction (and the corresponding recapture exposure), which is different from bonus depreciation that produces an NOL absorbed against future income under §172.
Real estate and cost segregation interaction
Real property buildings (the structural shell) don’t qualify for §179 or bonus depreciation. Buildings are depreciated under MACRS over 27.5 years (residential rental) or 39 years (nonresidential) using straight-line method. Land is not depreciable at all. But components of a building can qualify for §179 or bonus depreciation if they meet specific tests, and cost segregation is the engineering and tax study that identifies those components.
Qualified improvement property (QIP) under §168(e)(6) is the biggest category. QIP is any improvement made to the interior of nonresidential real property after the building was first placed in service. Excluded from QIP: improvements related to building enlargement, elevators or escalators, or the internal structural framework. Included: interior walls, ceilings, flooring, lighting, HVAC components serving specific zones (not the whole building), security systems, fire suppression. QIP has a 15-year MACRS recovery period and is eligible for 100% bonus depreciation under §168(k) and for §179 expensing under §179(d)(1).
Cost segregation studies allocate the purchase price of a building (or the construction cost) among the structural building (39-year property) and various components that qualify for shorter recovery periods. Personal property components (decorative lighting, signage, removable cabinetry, telephone systems, certain electrical and plumbing components) qualify as 5-year or 7-year MACRS property eligible for §179 and bonus. Land improvements (parking lots, fencing, landscaping) qualify as 15-year property eligible for bonus depreciation. The typical cost segregation study reclassifies 20% to 40% of a building’s total cost from 39-year to shorter-life property.
For 2026, the cost segregation play is more valuable than it has been in years. A $5,000,000 commercial building purchase with a cost segregation study reclassifying $1,500,000 to 5-, 7-, and 15-year property produces $1,500,000 of immediate deduction in year one through 100% bonus depreciation. Without the study, the same $5,000,000 building generates roughly $128,000 of first-year depreciation (over 39 years, prorated for mid-month placement). The first-year tax savings difference is roughly $290,000 at a combined 21% federal plus 9% state effective rate.
Section 179 is technically available on QIP and on certain real property improvements (roofs, HVAC, fire protection, alarm systems on nonresidential real property). The §179 election on QIP requires that the property be placed in service after the building was first placed in service, and the §179 deduction on these items is included in the overall $2.56M cap. Bonus depreciation is the more common vehicle for QIP because it has no income limitation, but §179 can be used when the business has sufficient income and wants to control the deduction asset-by-asset.
Real estate professional status under §469(c)(7) becomes much more valuable in 2026 because of the larger first-year deductions available through cost segregation plus 100% bonus depreciation. A real estate professional (defined as someone who spends more than 750 hours and more than half their personal services in real estate trades or businesses) can deduct rental real estate losses against other income without the §469 passive loss limitations. The combination of REPS, cost segregation, and 100% bonus depreciation can produce six-figure first-year deductions against W-2 income for high-earning real estate investors who also have an active spouse or themselves working full-time in real estate.
Short-term rental property (Airbnb, VRBO with average rental periods of 7 days or less under §469 regulations) is not classified as a rental activity under §469 and can produce deductions against other income without REPS qualification. The combination of short-term rental treatment and 100% bonus depreciation on personal property components (furniture, kitchen equipment, appliances) is one of the strongest tax plays in the OBBBA-revised code. A $1,500,000 short-term rental purchase with a cost segregation study reclassifying $400,000 to 5- and 7-year property can produce a $400,000 first-year deduction against W-2 income for the owner.
Recapture rules — §179 versus §168(k)
Recapture is what happens when business property that was §179-expensed or bonus-depreciated is sold, converted to personal use, or otherwise disposed of before the end of the MACRS recovery period. The recaptured amount is taxed as ordinary income, not capital gain. The recapture rules differ between §179 and bonus depreciation in ways that matter for asset disposition planning.
Section 179 recapture under §179(d)(10) applies when business use of §179 property drops below 50% during the recovery period. The recapture amount is the excess of the §179 deduction taken over what the depreciation would have been under regular MACRS for the years the property was in service. The recapture is reported in the year business use drops below 50%, not in the year of original deduction. The recapture income is ordinary, taxed at the taxpayer’s marginal rate plus self-employment tax if applicable for pass-through entities.
Example of §179 recapture: a business §179s a $50,000 piece of equipment in 2026, used 100% for business. In 2028, the equipment is converted to 30% business use (70% personal). The §179 deduction was $50,000. The MACRS depreciation that would have been taken over 2026 and 2027 on a 5-year property is roughly $35,000 (using DDB switching to straight-line under §168(b)). The recapture is $50,000 minus $35,000 equals $15,000 of ordinary income in 2028, plus the future-year depreciation on the property is recomputed based on the reduced business use percentage.
Bonus depreciation recapture works differently. Property bonus-depreciated under §168(k) and subsequently sold is subject to ordinary income recapture under §1245 (for personal property) or §1250 (for real property) to the extent of accumulated depreciation. The recapture rules are the same as for regularly depreciated property — there is no separate §168(k) recapture mechanism that fires on a change in business use. A change in business use after bonus depreciation just changes the future-year MACRS calculation, not the bonus deduction already taken.
This difference matters when you are deciding between §179 and bonus on an asset that might be sold or converted within the recovery period. Section 179 has the more aggressive recapture trigger (a drop below 50% business use triggers recapture in that year). Bonus depreciation has the standard sale-of-asset recapture under §1245/§1250. For assets likely to be sold within five years, either deduction produces ordinary income recapture on sale to the extent of accumulated depreciation. For assets where business use might drop below 50% (a vehicle used by an owner who might use it more personally as the business changes), §179 produces an unexpected mid-year tax bill that bonus does not.
Section 1245 recapture on sale of personal property treats all accumulated depreciation (including §179 and bonus) as ordinary income up to the gain on sale. So if a business §179s a $50,000 piece of equipment in 2026 and sells it in 2029 for $30,000, the depreciation taken was $50,000, the basis at sale is $0, and the gain is $30,000, all of which is recaptured as ordinary income under §1245. If the same equipment is sold for $70,000, the gain is $70,000, of which $50,000 is §1245 recapture (ordinary) and $20,000 is §1231 gain (potentially capital).
Section 1250 recapture on sale of real property is more favorable. The recapture is limited to the excess of accelerated depreciation over straight-line depreciation, which for most modern real property depreciated under MACRS straight-line is zero. Unrecaptured §1250 gain (the depreciation taken on real property) is taxed at a maximum 25% rate under §1(h)(1)(E), not the full ordinary income rate. The 25% rate applies to depreciation taken via cost segregation on real property components (specifically the 15-year QIP and similar items) when the real property is sold.
Planning around recapture: businesses planning to sell or refinance property within the recovery period should model the recapture exposure before electing maximum first-year deductions. The tax savings from immediate expensing can be partially offset by the ordinary income recapture on sale. For long-hold assets (10+ years), recapture is less of a concern because the time value of the early deduction outweighs the eventual recapture. For short-hold assets, the strategy needs more care, and bonus depreciation generally produces slightly more favorable recapture treatment than §179 (because §179 has the mid-recovery business-use trigger that bonus does not).
The Reed Corporation models the §179 and bonus depreciation choice on every significant equipment purchase for business clients. The analysis includes the current-year tax savings, the recapture exposure if the asset is sold within the recovery period, the interaction with the business’s overall depreciation strategy, the §179 carryforward implications if income is insufficient, and the entity-level treatment for pass-through entities (where the deduction passes through to owners’ individual returns and interacts with their personal §179 and bonus elections from other entities). The 2026 rules with the $2.56M §179 cap and permanent 100% bonus depreciation make these decisions even more impactful than in prior years because the first-year deductions are larger.
Frequently Asked Questions
What is the 2026 Section 179 expensing limit?
The 2026 Section 179 expensing limit is $2,560,000 per taxpayer per year, doubled from the 2025 limit of $1,250,000. The dollar-for-dollar phaseout begins when total qualifying property placed in service during 2026 exceeds $4,090,000, and the §179 cap is reduced by $1 for every $1 of qualifying property above the threshold. A business that places $5,090,000 of qualifying property in service in 2026 loses $1,000,000 of the §179 cap and is limited to $1,560,000 of §179 expensing. A business that places $6,650,000 or more of qualifying property in service is fully phased out of §179 entirely.
The $2.56M and $4.09M figures come from IRC §179(b)(1) and §179(b)(2), both of which are indexed for inflation under §179(b)(6). The IRS publishes the inflation-adjusted figures in the annual revenue procedure for each upcoming tax year. The 2026 numbers were published in Rev. Proc. 2025-32 from the IRS in October 2025. The figures will continue to climb in future years with inflation, though the rate of increase depends on the inflation measure used (chained CPI under §1(f)(3) post-TCJA).
The increase from $1,250,000 in 2025 to $2,560,000 in 2026 is not an inflation adjustment alone — it’s a statutory change made by the One Big Beautiful Bill Act (OBBBA). OBBBA increased the §179 cap, increased the phaseout threshold, and made other modifications to the §179 mechanics. The 2025 cap of $1,250,000 would have inflation-adjusted to roughly $1,290,000 for 2026 without the statutory change. OBBBA nearly doubled the cap as part of the broader business tax provisions in the bill.
The §179 cap applies per taxpayer, not per business. A single individual operating multiple businesses (as sole proprietor of one, member of an LLC, partner in a partnership, or shareholder of an S-corp) has a single $2.56M cap that applies across all the entities combined. The cap is computed at the individual level after the pass-through entities have made their entity-level §179 elections. If two pass-through entities both elect §179 on $2,000,000 of property each, the individual’s combined §179 from those entities is $4,000,000, of which only $2,560,000 is currently deductible at the individual level. The excess carries forward.
For married filing jointly couples, the $2.56M cap applies to the combined return. The IRS treats married couples as a single taxpayer for §179 purposes under §179(b)(4). A married couple where each spouse operates a separate business does not get two $2.56M caps — they share one cap across both businesses. This is different from the IRA contribution limits or other per-individual limits in the code, and it’s a common point of confusion for couples with two active businesses.
The $2.56M cap is a deduction limit, not a property limit. A business can place $4,090,000 of qualifying property in service and still §179 only $2,560,000 of it. The remaining $1,530,000 of property would be deducted via 100% bonus depreciation under §168(k) (since both rules layer on top of each other), so the practical effect is full first-year expensing of the full $4,090,000 in either case. The §179 cap doesn’t limit total first-year deductions when bonus depreciation is available at 100%.
Qualifying property under §179(d) is broader than many businesses realize. It includes machinery, equipment, computers and computer software, office furniture, vehicles (subject to the heavy SUV cap and §280F luxury auto limits), and certain qualified real property improvements (roofs, HVAC, fire protection, security systems on nonresidential real property). New and used property both qualify under §179, with the requirement that the property is used more than 50% for business in the year of placement. The 50% business use rule is critical for vehicles and home-office equipment.
The taxable income limitation under §179(b)(3) caps the §179 deduction at the business’s net taxable income from active trades and businesses computed without regard to the §179 deduction itself. A business with $1,000,000 of taxable income before §179 cannot deduct more than $1,000,000 of §179 in that year, regardless of the §2.56M cap. The unused §179 carries forward indefinitely and is deducted in future years when the business has sufficient taxable income. The carryforward is tracked on Form 4562 Part I Line 13 and continues to carry until used.
Real-world example: a manufacturing partnership places $2,200,000 of new equipment in service in 2026 and has $1,800,000 of partnership taxable income before any §179 election. The partnership elects §179 on $2,200,000 at the partnership level (under the $2.56M cap). The $2,200,000 deduction passes through to the two equal partners as $1,100,000 each on their Schedule K-1s. Each partner has individual taxable income of roughly $900,000 from the partnership before §179 and additional W-2 income from other sources of $200,000 each. Each partner’s §179 deduction is limited to their share of the partnership’s active business income ($900,000 each), so each partner can only deduct $900,000 of the $1,100,000 §179 in 2026. The remaining $200,000 per partner carries forward to 2027 at the partner level. The Reed Corporation models this kind of multi-level §179 limitation regularly for partnership and S-corp clients. The carryforward tracking can get complicated across multiple years and multiple pass-through entities, and we keep the §179 records at the individual partner/shareholder level along with the entity-level records. The 2026 increased cap of $2.56M provides much more headroom for large equipment purchases than the prior $1.25M cap, but the income limitation can still bind for businesses in transition years or after large capital outlays. Planning around income recognition timing (closing deals before or after year-end, accelerating or deferring billing, recognizing or deferring inventory adjustments) can help make the most of the immediate §179 deduction in years with large equipment purchases. The interaction between §179 income limits and the §469 passive activity rules adds another layer for owners of multiple pass-through entities, where active business income from one entity can absorb §179 deductions from another within the active-business income pool. Documentation of which entities count as active versus passive is the foundation of that calculation, and the §469 material participation tests need to be tracked carefully for owners with multiple business activities.
One often-missed planning angle: the $2.56M §179 cap is per taxpayer per year and doesn’t carry forward unused. A business that places only $400,000 of qualifying property in service in 2026 doesn’t get to add the unused $2.16M of cap to its 2027 capacity. The full cap is available each year if the business has qualifying property and sufficient active business income to absorb the deduction. Businesses planning multi-year capital programs sometimes consider spreading purchases across years to stay below the §179 phaseout threshold, but this is rarely the right strategy when 100% bonus depreciation is available because bonus has no investment-based phaseout at all. The smarter timing question is usually about taxable income absorption rather than cap headroom — making sure the business has sufficient active business income in the year of purchase to absorb the full §179 deduction without carryforward to a future year at either the entity level or the owner level.
Is 2026 bonus depreciation 100% or did it phase down?
2026 bonus depreciation is 100% and is now permanent. The One Big Beautiful Bill Act (OBBBA) revived 100% bonus depreciation under IRC §168(k) and removed the scheduled phasedown. The previous phasedown schedule had bonus at 80% (2023), 60% (2024), 40% (2025), 20% (2026), and 0% (2027). OBBBA replaced that schedule with 100% bonus depreciation indefinitely for property placed in service in 2026 and beyond.
The change is statutory and made through OBBBA amendments to §168(k). There is no sunset built into the new 100% rate. Future Congresses could change the rate again, but as of the OBBBA enactment, businesses can plan on 100% bonus depreciation as the permanent rule. This is a significant change from the prior regime where businesses had to time large equipment purchases against the declining bonus schedule.
Qualifying property under §168(k) includes most tangible personal property with a MACRS recovery period of 20 years or less, plus qualified improvement property (QIP) on nonresidential real property. New and used property both qualify, provided the property was not previously used by the taxpayer or a related party. Land and buildings themselves don’t qualify, but components of buildings reclassified through cost segregation can qualify if they fall within the 20-year recovery period limit.
Bonus depreciation is automatic on qualifying property unless the taxpayer elects out under §168(k)(7). The election out is made on a class-by-class basis for each MACRS class of property placed in service during the year (5-year property, 7-year property, 15-year property, etc.). The election is irrevocable without IRS consent. Most businesses don’t elect out because the cash-flow benefit of immediate expensing is significant and the alternative is multi-year depreciation under MACRS.
Bonus depreciation has no taxable income limitation, unlike Section 179. A business with a net operating loss can take 100% bonus depreciation and push the NOL deeper. This is the single most important strategic difference between bonus and §179. For loss-year businesses, startup-mode businesses, or businesses in heavy capital investment phases, bonus is the only mechanism for full immediate expensing because §179 is capped at active business income. The NOL generated by bonus carries forward under §172 and offsets future income up to 80% of taxable income in any year (post-2017 NOL rules).
Related-party transactions don’t qualify for bonus depreciation under §168(k)(2)(E)(ii) because the property must not have been used by the taxpayer or a related party before acquisition. The related-party definition is the same as in §267 and §707(b), covering spouses, ancestors, descendants, controlled entities, and certain trusts and partnerships. A business buying used equipment from a 50%-or-more owned related party cannot use bonus depreciation but can still use §179 on the property if other §179 requirements are met. This is one of the few scenarios where §179 is necessary even when bonus is otherwise available.
Qualified production property is a new category under OBBBA that gets special bonus depreciation treatment. The OBBBA added a permanent 100% bonus deduction for certain manufacturing-related real property used to produce goods in the United States. The definition is technical and the IRS will issue further guidance, but the broad effect is that manufacturing facilities placed in service after 2026 may get full first-year expensing on the entire facility cost, including the building shell. This is a significant expansion of bonus depreciation beyond the prior limits.
Real-world example of bonus depreciation in action: a tech startup places $2,800,000 of computer equipment, $400,000 of office furniture, and $600,000 of qualified improvement property in service in 2026. Total qualifying property: $3,800,000, below the §179 phaseout threshold but above the §179 cap. The business has a $500,000 operating loss for the year before depreciation. Using bonus depreciation on the full $3,800,000, the business produces a $4,300,000 NOL ($500,000 operating loss plus $3,800,000 depreciation). The NOL carries forward to offset up to 80% of future taxable income each year under §172(a)(2). Using §179 only, the business would be limited to deducting against its (negative) active business income, producing $0 of current-year §179 deduction. Bonus depreciation is the only mechanism that achieves the full $3,800,000 deduction in a loss year.
The Reed Corporation works with business clients on the §179 versus bonus depreciation decision for every significant capital expenditure. The 2026 rules with 100% permanent bonus depreciation make this decision easier in many cases because both rules produce 100% first-year expensing, and the choice comes down to mechanical preferences (election out flexibility, recapture exposure on potential dispositions, taxable income limitations) rather than dollar-amount differences. For most operating businesses in profitable years, the choice between §179 and bonus is neutral in dollar terms and the §179 election is made for control over which assets get expensed. For businesses in loss years or businesses with large capital expenditures exceeding the §179 cap, bonus depreciation is the primary or exclusive vehicle for first-year expensing. The permanence of 100% bonus under OBBBA means that multi-year capital planning can rely on full first-year expensing as a stable assumption, removing one of the major timing uncertainties that businesses faced during the 2023-2027 phasedown period. The change also affects financial reporting and book-tax differences for businesses that prepare GAAP or other accrual-basis financial statements, where book depreciation continues over the asset’s useful life while tax depreciation is fully accelerated. The resulting deferred tax liability is now a permanent feature of the balance sheet rather than a temporary one that would have unwound as bonus depreciation phased out. The book-tax difference matters for businesses with debt covenants tied to EBITDA or net income calculations, where the bonus depreciation strategy can affect compliance with covenants in unexpected ways. The decision to take bonus depreciation, while almost always tax-favorable, sometimes has financial reporting consequences that need to be modeled before the election is made.
One more wrinkle on the 100% bonus permanence: the placed-in-service date governs which bonus rate applies, and properties placed in service in late 2025 versus early 2026 face dramatically different treatment. A business that ordered equipment in November 2025 but didn’t take delivery and install it until January 2026 captures the 100% bonus rate. A business that took delivery and placed the same equipment in service in December 2025 is stuck with the 40% bonus rate that was the 2025 phasedown level. The difference is significant: on a $500,000 piece of equipment, the year-one bonus deduction differs by $300,000 between the two scenarios, with the rest depreciating over MACRS in subsequent years. For businesses with year-end equipment purchases in late 2025, deferring the placed-in-service date by a few weeks into January 2026 was worth real money. The 2026 and forward years benefit from the permanent 100% rate without any timing wrinkle, which is one of the cleanest aspects of the OBBBA change for ongoing capital planning.
When should I use Section 179 vs bonus depreciation in 2026?
The general rule for 2026: use Section 179 first for control over which specific assets get expensed, then apply 100% bonus depreciation under §168(k) to anything §179 doesn’t cover. Both rules produce 100% first-year expensing in 2026, so the choice between them is about mechanics, flexibility, and edge cases rather than total deduction amount in most situations. The differences matter, but they are tactical rather than strategic in a profitable year for most businesses.
Use Section 179 when you want asset-specific control over which property gets expensed. Section 179 is elected on an asset-by-asset basis on Form 4562 by listing each item and the §179 amount for that item. A business can §179 a specific piece of equipment and not others within the same MACRS class. Bonus depreciation is all-or-none within a MACRS class for the year — the business either takes bonus on everything in the 5-year class or elects out of bonus for the entire 5-year class. The asset-specificity of §179 provides more flexibility for unusual situations.
Use bonus depreciation when you don’t have enough business income to absorb §179. Section 179 is limited to the business’s net taxable income from active trades and businesses under §179(b)(3). A business with a net operating loss cannot use §179 to push the loss deeper. Bonus depreciation has no such limitation and can be used to create or expand a net operating loss. For loss-year businesses, startup-mode businesses, or businesses in heavy capital investment phases, bonus depreciation is the only path to full first-year expensing.
Use Section 179 when you bought property from a related party. Bonus depreciation under §168(k)(2)(E)(ii) requires that the property was not used by the taxpayer or a related party before acquisition. Section 179 has no such restriction. A business buying used equipment from a 50%-or-more related party can §179 the equipment but cannot bonus depreciate it. This is the most common scenario where §179 is structurally necessary rather than just preferred.
Use bonus depreciation when your equipment purchase exceeds the §179 phaseout. The §179 cap of $2.56M (2026) phases out dollar-for-dollar above $4.09M of qualifying property placed in service. A business that places $5.5M of property in service has its §179 cap reduced to $1.15M, with the remaining $4.35M deducted via 100% bonus depreciation if it qualifies. A business that places more than $6.65M of property in service is fully phased out of §179 entirely, with the full deduction coming through bonus. For large capital expenditure years, bonus is the primary deduction mechanism.
Use Section 179 when the asset might have business use drop below 50% later. Section 179 recapture under §179(d)(10) fires when business use drops below 50% during the recovery period. The recapture is computed as the excess of §179 deduction taken over MACRS depreciation that would have been allowed. Bonus depreciation doesn’t have this mid-recovery recapture trigger — the only recapture is on actual sale or disposition of the asset. This sounds like a reason to use bonus instead of §179, but the asset-by-asset flexibility of §179 actually lets the business avoid §179 on assets likely to have business use drop, while still taking §179 on assets that will remain in business use.
Use bonus depreciation for QIP and real property improvements without income concerns. Qualified improvement property and certain real property improvements (roofs, HVAC, fire protection, alarm systems on nonresidential real property) qualify for both §179 and bonus depreciation. For businesses with sufficient income to absorb either deduction, the choice is essentially neutral. For businesses with marginal income, bonus depreciation avoids the §179 income limitation and gives a cleaner deduction.
Layer both for maximum control in 2026. The optimal strategy for most profitable businesses with large 2026 equipment purchases is to elect §179 on a strategically chosen subset of assets up to the $2.56M cap, then take 100% bonus depreciation on the remainder. The §179 election is used on assets where future recapture exposure is low (long-hold assets), where business income is sufficient to absorb the deduction without limitation, and where the asset-specific control of §179 is valuable. Bonus depreciation is used on everything else in the qualifying property categories. The combined first-year deduction equals the total cost of all qualifying property, regardless of how the §179 and bonus are allocated.
Real-world example: a manufacturing S-corp places $3,200,000 of equipment in service in 2026, consisting of $1,800,000 of 5-year MACRS machinery and $1,400,000 of 7-year MACRS production equipment. The business has $2,400,000 of taxable income before depreciation. Strategy: elect §179 on $2,400,000 of the property (capped by taxable income, even though the $2.56M cap allows more), and take 100% bonus depreciation on the remaining $800,000. Total first-year deduction: $3,200,000, exactly matching the equipment cost. The §179 election uses the 7-year property first (longer recovery, more deferred tax otherwise) and then fills in with 5-year property up to $2,400,000. The bonus depreciation covers the remaining 5-year property. This layered approach makes the most of the first-year deduction and preserves the §179 income limit for the longer-recovery assets where the timing benefit is largest.
The Reed Corporation runs this calculation for every business client with significant 2026 equipment purchases. The decision tree is mechanical once the facts are clear: taxable income before depreciation, total qualifying property by MACRS class, related-party transactions, asset-specific factors like expected hold period and risk of business use dropping below 50%, and the entity’s overall tax planning strategy. The 2026 rules with the $2.56M §179 cap and permanent 100% bonus depreciation give businesses more flexibility than at any point since 2017, and the planning is more about improving the mechanical structure than about choosing between competing partial deductions. For pass-through entities (partnerships and S-corps), the analysis extends to the individual partners or shareholders, who have their own §179 income limitations at the personal level. A partnership-level §179 election that exceeds an individual partner’s active business income from all sources gets limited at the partner level and carries forward at that level, which can produce surprising results if the partnership doesn’t communicate the §179 information clearly on the Schedule K-1. We track all of this for clients across the entity and individual returns to make sure the §179 election produces the intended first-year deduction and the carryforwards are reflected accurately in subsequent years. The §179 carryforward tracking is one of the most commonly mishandled items in pass-through tax returns, and the increased $2.56M cap means more dollars at stake when the tracking is wrong.
Does the 2026 Section 179 limit apply to vehicles and SUVs?
Vehicles are subject to several layered limitations that intersect with the §179 cap. The general $2.56M §179 cap applies to vehicles like other qualifying property, but vehicles also face the separate §280F passenger automobile depreciation limits for vehicles under 6,000 lbs GVWR, and the separate $32,000 heavy SUV cap under §179(b)(5) for vehicles between 6,000 and 14,000 lbs GVWR. Vehicles over 14,000 lbs GVWR escape the vehicle-specific caps entirely and are subject only to the general $2.56M §179 cap.
Passenger automobiles under §280F(a) (vehicles under 6,000 lbs GVWR) are subject to the §280F luxury auto depreciation limits, which cap first-year depreciation at $20,400 for 2026 (including any §179 or bonus depreciation). This applies to passenger cars and light trucks under 6,000 lbs. A business buying a $70,000 luxury sedan in 2026 is capped at $20,400 of first-year depreciation regardless of §179 or bonus elections. The remaining cost is depreciated under the §280F limits over the recovery period. For passenger autos, §179 and bonus are essentially meaningless because the §280F cap binds first.
Heavy SUVs (vehicles between 6,000 and 14,000 lbs GVWR) face the separate $32,000 §179 cap under §179(b)(5). The cap is separate from and additional to the general $2.56M §179 cap, not in lieu of it. A business can §179 up to $32,000 on a heavy SUV in 2026 and then use the remaining §179 capacity on other equipment up to the $2.56M overall cap. The $32,000 cap on heavy SUVs is designed to prevent the §179 deduction from fully expensing luxury SUVs, which Congress was concerned about when the heavy SUV cap was added in 2003.
Bonus depreciation under §168(k) is NOT subject to the $32,000 heavy SUV cap. A business that buys a $90,000 heavy SUV in 2026 and uses it 100% for business can §179 $32,000 and bonus depreciate the remaining $58,000 under §168(k), achieving full first-year expensing of $90,000. This is the standard play for heavy SUV purchases in 2026. The combination of §179 (up to $32,000) plus 100% bonus on the remainder produces full first-year expensing without hitting the §280F passenger auto caps (which don’t apply to vehicles over 6,000 lbs GVWR).
Vehicles over 14,000 lbs GVWR (heavy commercial vehicles like dump trucks, semi tractors, large delivery trucks) escape both the §280F passenger auto caps and the §179(b)(5) heavy SUV cap. These vehicles are subject only to the general $2.56M §179 cap and to 100% bonus depreciation under §168(k). A business can §179 the full cost of a $250,000 dump truck in 2026 (up to the overall §2.56M cap) or bonus depreciate the full cost under §168(k). Heavy commercial vehicles are the cleanest case for full first-year expensing.
The 50% business use requirement applies to vehicles for both §179 and bonus depreciation. A vehicle used less than 50% for business loses §179 and bonus eligibility entirely and is depreciated under straight-line method over the §280F recovery period (5 years for most automobiles, plus the §280F limits). The business-use percentage is recalculated annually, and if business use drops below 50% in a later year, prior-year §179 and bonus depreciation can be recaptured as ordinary income. Mileage logs and business-use documentation are essential for any vehicle used in mixed personal and business activities.
Section 179 vehicle recapture under §179(d)(10) is more aggressive than bonus recapture. If a vehicle that was §179-expensed drops below 50% business use during the recovery period, the §179 deduction is recaptured as ordinary income to the extent it exceeded what straight-line depreciation would have allowed. Bonus depreciation doesn’t have this mid-recovery business-use trigger. For vehicles likely to have variable business use over time (a vehicle used by an owner who might use it more personally as the business changes), this difference can matter.
Real-world example: a real estate brokerage buys a $95,000 Cadillac Escalade in 2026 with 6,800 lbs GVWR (heavy SUV class), used 100% for business. The owner can §179 $32,000 of the cost and take 100% bonus depreciation on the remaining $63,000, producing a $95,000 first-year deduction. The combined deduction at a combined 30% federal-plus-state effective rate produces $28,500 of tax savings in the year of purchase. Without bonus depreciation, only $32,000 would be deductible immediately (§179 cap on heavy SUVs), with the remaining $63,000 depreciated over 5 years under MACRS, producing $9,600 of first-year tax savings. The bonus depreciation revival under OBBBA increases the year-one benefit on the Escalade by nearly $20,000 of tax savings.
Listed property documentation requirements under §274(d) apply to vehicles used for business. The taxpayer must maintain a contemporaneous log of business and personal mileage, including the date, destination, business purpose, and miles driven for each business trip. The log can be paper, spreadsheet, or app-based (MileIQ, TripLog, Stride). The IRS routinely audits vehicle deductions and disallows §179 and bonus depreciation when the mileage log is missing or insufficient. The documentation burden is real but manageable with consistent recordkeeping habits.
The Reed Corporation handles vehicle deductions for business clients across the full range of vehicle types and use patterns. The most common scenarios involve heavy SUV purchases by service business owners (real estate agents, contractors, consultants) who want full first-year expensing. The combination of §179 plus bonus depreciation in 2026 produces full expensing for these vehicles, but the documentation requirements and the future-year business-use risk need to be managed carefully. We help clients set up the mileage tracking systems, structure the purchase to make the most of first-year deduction, and plan for the recapture exposure if business circumstances change. For clients with multiple vehicles across personal and business use, we coordinate the §179, bonus, and §280F treatment across all vehicles to improve the overall household tax position. The intersection of vehicle tax rules with §469 passive activity, §263A capitalization rules, and entity-level versus owner-level §179 limitations can get complex, but the underlying mechanics are stable once the facts are clear. For 2026, the permanence of 100% bonus depreciation makes heavy SUV purchases especially attractive for businesses that genuinely need a larger vehicle for business purposes, because the combined §179 plus bonus produces full first-year expensing regardless of vehicle cost (up to the practical limit of the §2.56M overall cap).
How do I report 2026 Section 179 and bonus depreciation on Form 4562?
Form 4562, Depreciation and Amortization, is the IRS form used to report §179, bonus depreciation, and regular MACRS depreciation for all property placed in service during the year. The form is filed with the business’s annual return (Form 1040 Schedule C for sole proprietors, Form 1065 for partnerships, Form 1120-S for S-corps, Form 1120 for C-corps) and provides the IRS with the details of every asset depreciated during the year.
Part I of Form 4562 reports the §179 election. Line 1 shows the maximum §179 dollar limit ($2,560,000 for 2026). Line 2 shows the total cost of §179 property placed in service. Line 3 shows the threshold cost of §179 property before the phaseout reduces the dollar limit ($4,090,000 for 2026). Line 4 shows the reduction in the limit due to the phaseout. Line 5 shows the dollar limit for the tax year after the phaseout reduction. Lines 6 through 12 list the specific properties, the §179 amount elected for each, and the total §179 deduction subject to the income limitation. Line 13 is the §179 carryover from prior years.
Each specific asset elected for §179 is listed individually on Line 6 of Part I, with the description, cost, and §179 election amount. This is where the asset-by-asset specificity of §179 lives in the reporting. A business that §179s a $50,000 piece of equipment and a $30,000 vehicle would list both on Line 6 with the specific §179 amounts elected for each ($50,000 and $30,000 respectively, totaling $80,000 of §179). The form footnotes guide which line shows what.
Part II of Form 4562 reports the special depreciation allowance under §168(k), which is the bonus depreciation. Line 14 is the special depreciation allowance for qualified property placed in service during the year. The 100% bonus depreciation under OBBBA appears here as the full cost of bonus-eligible property not already expensed under §179. For a business that placed $3,200,000 of qualifying property in service and §179’d $2,400,000, the bonus depreciation on the remaining $800,000 would appear on Line 14 of Part II.
Part III of Form 4562 reports the regular MACRS depreciation on property not fully expensed under §179 or bonus. The MACRS depreciation is computed based on the property’s classification (3-year, 5-year, 7-year, 10-year, 15-year, 20-year, 27.5-year, or 39-year property) and the applicable convention (half-year, mid-quarter, or mid-month). With 100% bonus depreciation in 2026, most personal property won’t have residual MACRS depreciation to report in Part III because the full cost was expensed via §179 or bonus.
Part IV of Form 4562 is the summary section, which totals the depreciation from Parts I, II, and III. This is the line that ultimately flows to the business’s main return — Schedule C for sole proprietors, Page 1 of Form 1065 or 1120-S for pass-through entities, or Page 1 of Form 1120 for C-corps. The total depreciation deduction includes §179, bonus, and regular MACRS combined.
Part V of Form 4562 covers listed property under §280F, including vehicles under 6,000 lbs GVWR, certain entertainment-related property, and certain computer equipment used outside a regular business establishment. Listed property requires more detailed documentation, including the business-use percentage, total miles driven (for vehicles), and substantiation of business purpose. The §280F luxury auto limits are reported in Part V, and the §179 and bonus depreciation amounts subject to the limits are computed and shown here.
Part VI of Form 4562 covers amortization, which is mostly relevant for intangible assets (goodwill, software, organizational costs) that are amortized rather than depreciated. Section 197 intangibles have a 15-year amortization period and don’t qualify for §179 or bonus depreciation. Off-the-shelf computer software is treated differently and can qualify for §179 under §179(d)(1)(A)(ii) if placed in service in a trade or business.
Filing mechanics: Form 4562 is required for any business that placed property in service during the year, including pass-through entities and individual taxpayers with Schedule C, Schedule E, or Schedule F activities. The form is filed at the business or entity level, with the depreciation totals flowing to the appropriate lines of the main return. Pass-through entities issue Schedule K-1s to owners showing the §179 election and the owner’s share, and the individual owners then complete their own Form 4562 if they have any individual-level adjustments or other business activities.
Common Form 4562 errors include omitting the §179 carryforward from prior years (Line 13 of Part I), failing to apply the taxable income limitation correctly (resulting in §179 deductions that exceed allowable amounts), incorrectly classifying property in the wrong MACRS class (e.g., treating 7-year property as 5-year), missing the bonus depreciation election out for property classes where the taxpayer wanted to elect out, and failing to file Form 4562 at all when required.
The Reed Corporation prepares Form 4562 for every business client with depreciable property, which is essentially every business client. The form is straightforward when the underlying data is clean: a complete fixed asset schedule with placed-in-service dates, costs, MACRS classifications, §179 elections, bonus depreciation amounts, and business-use percentages for listed property. The complexity comes from edge cases — assets with mixed personal and business use, related-party transactions, §179 carryforwards from multiple prior years, pass-through entity allocations, and the interaction with §469 passive activity rules. For 2026 with the increased §179 cap and permanent 100% bonus depreciation, the form is more important than ever because the first-year deductions are larger and the dollar amounts at stake in any reporting error are correspondingly bigger. We maintain detailed fixed asset records for clients across multiple years to make sure the §179 carryforwards, the bonus depreciation amounts, and the regular MACRS schedules are all tracked accurately and reflected correctly on each year’s Form 4562. The audit defense on §179 and bonus depreciation is the underlying documentation, and Form 4562 is the official record of what was claimed. Clients who maintain clean fixed asset records (purchase dates, costs, business-use percentages, classification rationale) sail through any IRS scrutiny on depreciation. Clients with messy records face proposed adjustments and the cost of reconstructing the records under audit conditions. The administrative cost of keeping clean records up front is much lower than the cost of reconstructing them later, which is one of the reasons we push business clients to set up proper fixed asset tracking systems early in the year rather than scrambling at year-end.
