Form 8825 for Partnership and S-Corporation Rental Real Estate: Mechanics, K-1 Flow, and the §469 Passive Activity Trap

What Form 8825 is and why it isn’t on Form 1065 directly

Form 8825, Rental Real Estate Income and Expenses of a Partnership or an S Corporation, reports each rental property the entity owns. The form is filed as an attachment to Form 1065 (partnerships) or Form 1120-S (S-corporations).

Why a separate form. Rental real estate income retains a distinct character — it’s passive activity income under IRC §469 absent material participation by the owner. The §469 rules apply at the partner or shareholder level, not the entity level. So the entity calculates rental net income on Form 8825 and passes it through on the K-1 separately from ordinary business income on Form 1065 line 1.

If rental income were reported on line 1 (ordinary business income), it would lose the passive-activity tracking that §469 requires. The K-1 separates them: line 1 is ordinary business income/loss; line 2 is net rental real estate income/loss; line 3 is other net rental income/loss (such as personal property rentals). Each line gets separate §469 treatment at the owner level.

Per-property reporting. Each rental property the entity owns gets a separate column on Form 8825. So a partnership owning 8 rental properties has 8 columns on Form 8825 — or multiple Form 8825s if more than 8 properties. The columnar layout shows gross rents, deductible expenses by category, depreciation, and net income or loss per property.

Aggregation at the bottom. The form totals all properties to produce the entity-level net rental real estate income or loss that flows to K-1 line 2.

Form mechanics. Rents received report at the top. Expenses by category — advertising, auto and travel, cleaning and maintenance, commissions, insurance, legal and professional fees, interest, repairs, taxes, utilities, wages and salaries, depreciation, and “other” — list separately for each property. Net income or loss per property calculates at the bottom.

Critical distinctions from Schedule E. The form looks structurally similar to Schedule E that individual landlords file, but the pass-through context changes several things. Depreciation at the entity level uses entity-level basis (which may differ from partner-level outside basis after §704(b) capital account allocations). §469 applies at the owner level not the entity level. Self-employment tax doesn’t apply to rental income passed through (unless converted to ordinary income via material participation in real-estate-as-trade-or-business arrangements).

Real estate professional status. Critical point. Under IRC §469(c)(7), individuals who qualify as real estate professionals can treat their rental activities as non-passive. The qualification requires more than 750 hours in real property trades or businesses and more than half of personal services in such trades. The qualification is individual. If a partnership owns the property and an individual partner qualifies as a real estate professional, the partner’s distributive share of rental loss from that partnership can offset non-passive income at the partner level — but only if the partner can also establish material participation in the rental activity. The entity itself can never be a real estate professional. Form 8825 just reports the activity; the qualification analysis happens at the partner’s individual return.

Filing requirements. Any partnership or S-corp with rental real estate must file Form 8825. Even if there’s no income (e.g., the property is vacant or in renovation), the form must still be filed to claim depreciation and expenses generating a loss. Failure to file when required can trigger §6038 penalties or §6651 late-filing penalties.

Pass-through to single-member LLC. A single-member LLC that hasn’t elected corporate or S-corp treatment is disregarded for federal tax purposes. Its rental real estate flows directly to the owner’s Schedule E, not through Form 8825. The form is only for multi-member partnerships and S-corporations. This distinction trips up new owners regularly.

The K-1 line 2 mechanics — why it matters where the income lands

K-1 line 2 captures net rental real estate income or loss for each partner or shareholder. The number derives directly from Form 8825’s bottom-line total allocated by ownership percentage (with potential modifications under §704(b) for partnerships).

Why line 2 specifically. The K-1 has multiple income categories because each gets different treatment at the owner level: line 1 (ordinary business income, subject to self-employment tax for general partners and managing members), line 2 (net rental real estate income, passive under §469), line 3 (other net rental income, passive), line 4 (guaranteed payments), line 5 (interest income, portfolio), line 6 (dividends, portfolio), line 7 (royalties, portfolio), line 8 (capital gains), and so on.

Owners separate the K-1 lines on their individual returns. Line 2 income flows to Schedule E Part II for partnerships and S-corps, where it’s treated as passive activity income/loss under §469. Line 2 losses are limited at the owner level unless offset by passive income or by the real estate professional exception.

§469 passive activity rules. Under §469(a), losses from passive activities can only offset income from other passive activities. They cannot offset wages, business income from non-passive activities, portfolio income, or capital gains. Suspended passive losses carry forward indefinitely and release at disposition of the activity in a fully taxable transaction.

Rental real estate is per se passive under §469(c)(2) regardless of participation level — with one major exception. Real estate professionals under §469(c)(7) can treat their rental activities as non-passive if they also materially participate in each activity.

Material participation tests. §469(h) lists seven tests, any one of which qualifies. The most common: 500 hours per year in the activity, or substantially all of the participation in the activity, or more than 100 hours and more than anyone else. For rental real estate, the 500-hour test is usually the operative one.

Aggregation election. A real estate professional can elect under Treas. Reg. §1.469-9(g) to aggregate all rental real estate activities as one activity for material participation testing. Without the election, each property must meet material participation separately — a near-impossibility for owners of multiple properties. With the election, the 500 hours can be spread across the portfolio. The election is made on the individual’s return, not at the entity level.

Active participation exception ($25,000 allowance). Under §469(i), individuals who actively participate in rental real estate (a lower standard than material participation) can deduct up to $25,000 of rental loss against non-passive income. The allowance phases out as AGI exceeds $100,000, eliminated entirely at $150,000 AGI. For most owners with significant non-rental income, this exception doesn’t apply.

Self-rental rule. Under Treas. Reg. §1.469-2(f)(6), rental income from property leased to a trade or business in which the taxpayer materially participates is reclassified from passive to non-passive. The result: the rental income can offset other non-passive income, but the rental loss (if the activity is in loss) is still passive. The asymmetry is intentional. Self-rental is a common scenario when an S-corp operating business pays rent to a partnership-owned building owned by the same individuals.

Suspended losses at disposition. When the entity disposes of a rental property in a fully taxable transaction (sale, abandonment, full distribution), suspended passive losses from that activity release at the owner level. The owner can deduct them against ordinary income in the year of disposition. This is a major exit-planning tool — accumulated suspended losses on a property can offset gain on sale and produce significant tax savings.

Like-kind exchange impact. A §1031 exchange isn’t a fully taxable disposition. Suspended losses from the relinquished property carry over to the replacement property under §469(g). The exchange doesn’t release the suspended losses. Important for owners planning exit timing.

Depreciation on Form 8825 — 27.5 vs 39 and cost segregation

Depreciation is the biggest single line item on Form 8825 for most rental properties. Getting it right is mechanical but mistakes compound over decades.

Residential vs commercial. IRC §168(c) and (e) set the recovery periods. Residential rental property (defined as buildings or structures with 80% or more of gross rental income from dwelling units) depreciates over 27.5 years straight-line. Nonresidential real property depreciates over 39 years straight-line.

The 80% test. A mixed-use property with retail on the ground floor and apartments above qualifies as residential if 80% or more of gross rents come from the residential units. If retail rents exceed 20% of total gross rents, the whole property becomes nonresidential and depreciates over 39 years.

MACRS conventions. Mid-month convention applies to all real property under §168(d)(4)(B). The placed-in-service date determines first-year depreciation. A building placed in service in October gets 2.5 months of depreciation (October 15 through December) in year 1 of a 27.5-year residential schedule, calculated as $building_basis × (2.5/12) / 27.5.

Land basis is excluded. Depreciation runs only on building basis, not land. Acquisition cost must be allocated between land and improvements at acquisition. The IRS expects reasonable allocation based on property tax assessment ratios, appraisals, or other supportable methods. Default to property tax assessment ratio is common: if the assessor allocates 30% to land and 70% to improvements, use that ratio.

Cost segregation. A cost seg study breaks out 5-year personal property (carpeting, cabinetry, appliances, decorative lighting), 15-year land improvements (parking, landscaping, fencing, signage), and 27.5- or 39-year structural property. The 5- and 15-year components depreciate faster and qualify for bonus depreciation.

Bonus depreciation. The TCJA’s 100% bonus phase-down (80% in 2023 and 60% in 2024, with the One Big Beautiful Bill Act restoring 100% for property acquired after January 19, 2025) was reversed by the OBBBA in 2025. Property placed in service after January 19, 2025 qualifies for 100% bonus depreciation. So acquisitions in 2025 (post-1/19) and 2026 benefit fully.

Cost seg + 100% bonus = massive first-year deductions. A $4M commercial property with 30% segregated into 5/15-year components ($1.2M) and 100% bonus eligible produces a $1.2M first-year deduction. At a partner’s 32-37% marginal rate, that’s $384K-$444K of tax savings allocated through K-1s.

Look-back cost seg studies. Properties placed in service in earlier years can be cost-segged retroactively via Form 3115 method change. The §481(a) catch-up captures the depreciation that should have been taken in prior years. Most cost seg studies pay for themselves 5-10x over.

Reporting on Form 8825. Depreciation is line 14 of Form 8825. The number aggregates depreciation across all classes for the property — building, land improvements, and personal property. Form 4562 provides the underlying detail and is attached to the entity return.

Partner-level basis tracking. Each partner has an outside basis in the partnership interest that tracks separately from the entity’s inside basis in the property. Depreciation reduces both — outside basis decreases by the partner’s distributive share of depreciation. Outside basis can’t go below zero, so heavily depreciated partners may see losses suspended at the basis level (separate from §469 passive loss limits).

Section 754 election. When a partner dies or transfers an interest, a §754 election allows the entity to step up the inside basis of partnership assets by the transferee’s portion. The step-up generates additional depreciation deductions for the transferee. The election is mechanical but mistakes happen — many partnerships don’t have a §754 election in place and lose the basis step-up opportunity on death.

Section 163(j) business interest limitation

IRC §163(j) limits the deduction for business interest expense to 30% of adjusted taxable income (ATI) plus business interest income plus floor plan financing interest. The limit applies at the entity level for partnerships and S-corps with rental real estate.

Aggregate gross receipts exception. Entities with average annual gross receipts of $30M or less ($31M for 2026 inflation-adjusted) over the prior three years are exempt from §163(j) entirely. Most individual real estate investors fall under this threshold. Larger portfolios and institutional owners may not.

Real estate election out. Under §163(j)(7)(B), real property trades or businesses can elect out of §163(j) by electing to use ADS (alternative depreciation system) instead of MACRS. ADS extends depreciation periods to 30 years for residential rental and 40 years for nonresidential. The election is irrevocable.

Tradeoff. Electing out of §163(j) preserves the interest deduction but slows depreciation. For highly-used properties, the interest preservation is worth more than the slower depreciation. For low-use properties, the inverse may be true. Model both scenarios.

Electing real property trade or business (ERPTB) consequences. The ADS election applies to all residential and nonresidential real property and to qualified improvement property. The election doesn’t apply to personal property components (still MACRS). Cost segregation continues to work — 5-year and 15-year components stay on MACRS even with the §163(j) election.

Reporting on Form 8825 and Schedule K. Interest expense is line 9 of Form 8825. The §163(j) limitation, if applicable, is calculated on Form 8990 at the entity level. Disallowed business interest expense is carried over and tracked at the partner/shareholder level via Schedule K-1.

Coordination with §469. Interest disallowed under §163(j) doesn’t carry forward as passive — it carries forward as business interest. So the character at the partner level after release matches the original character.

Practical example. Partnership owns $20M of rental properties with $14M of mortgage debt at 6% interest = $840K annual interest expense. Net rental income before interest: $1.2M. ATI ≈ net rental income before interest + depreciation. With $500K of depreciation, ATI ≈ $1.7M. 30% of ATI = $510K. Business interest deduction limited to $510K. Disallowed: $840K − $510K = $330K. Carries forward.

Same partnership elects out as ERPTB and uses ADS. Depreciation drops from $500K to roughly $380K (residential rental 30-year ADS vs 27.5-year MACRS produces ~24% slower depreciation, but the gap is smaller than the 30-year vs 27.5-year ratio suggests because the property is past first-year mid-month effects). Loses $120K of depreciation deduction. Gains $330K of interest deduction. Net benefit: $210K. Election makes sense.

If aggregate gross receipts under $31M and §163(j) doesn’t apply at all, no election needed. Most small partnerships fall here.

Important nuance. The §163(j) election out is irrevocable. Once elected, the ADS treatment continues for the duration of the property’s life. If circumstances change (e.g., use drops, partnership reorganizes), you can’t go back to MACRS. The election is structural.

Self-rental rules under §1.469-2(f)(6)

The self-rental rule under Treas. Reg. §1.469-2(f)(6) recharacterizes rental income from property leased to a trade or business in which the taxpayer materially participates. The result: rental income is non-passive (can offset other non-passive income), but rental losses remain passive (limited by §469).

Common scenario. Owner has an operating business in S-corp form and owns the operating real estate in a separate partnership or LLC. The S-corp pays rent to the partnership. The partnership owners materially participate in the S-corp.

Without the self-rental rule. The partnership’s rental income would be passive at the owner level. Without other passive income to absorb it, the income is treated as passive but generally produces zero passive losses to offset against. So passive income from a profitable property has nowhere to go on the owner’s return — it’s just taxed.

With the self-rental rule. The rental income is recharacterized as non-passive. The income flows through to the owner’s K-1 line 2 but is reclassified at the individual level as non-passive. It can offset other non-passive income (e.g., the owner’s wages from a separate job).

But losses stay passive. The asymmetric treatment is intentional. Owners can’t game the self-rental rule by intentionally generating losses on a self-rental property to offset other non-passive income. The losses remain passive and limited.

Reporting mechanics. Form 8825 doesn’t change — the partnership still reports rental income normally. The recharacterization happens at the owner’s individual return via Form 8582 and an attached statement explaining the self-rental treatment.

Documenting material participation. The taxpayer must materially participate in the trade or business that is the tenant. The 7 material participation tests of §469(h) apply. Owners typically document via written time logs, calendars, board meeting minutes, and operational involvement records.

Grouping election. A taxpayer can elect under Treas. Reg. §1.469-4(c) to group the rental activity with the operating business for §469 purposes if (a) they form an appropriate economic unit and (b) the grouping isn’t artificial. Common groupings: rental of operating real estate to the operating business. The grouping eliminates the self-rental issue because the activities are treated as one combined activity. Material participation in the combined activity satisfies the test.

Audit risk. The IRS challenges self-rental and grouping positions frequently. Documentation matters. The grouping election once made is binding for future years unless undone with IRS consent (rare).

Self-charged interest under §1.469-7. Similar concept for interest. Owner-to-entity loans where the entity pays interest and the owner has a passive interest in the entity get recharacterized. The owner’s interest income that would normally be portfolio income is recharacterized as passive to the extent it represents a deduction at the entity level allocable to a passive activity of the owner.

Practical example. Owner lends $500K to the partnership at 6% interest. Partnership pays $30K of interest annually. At the entity level, the interest is deductible against rental income on Form 8825. At the owner level, $30K of interest income is recharacterized as passive (to the extent of the owner’s passive share of the partnership). This allows it to be absorbed by passive losses the owner might have.

Section 1031 like-kind exchange reporting at the entity level

A partnership or S-corp that exchanges one rental property for another under IRC §1031 reports the exchange at the entity level on Form 8824. The gain deferral applies to the entity, not the individual partners.

Real property only. TCJA limited §1031 to real property exchanges. Personal property exchanges no longer qualify. So a partnership swapping office buildings for warehouses still qualifies. A partnership swapping equipment doesn’t.

Like-kind real property. Real property held for productive use in trade or business or investment can be exchanged for other like-kind real property. “Like-kind” for real property is broad — almost any productive-use or investment real property qualifies. A retail building exchanged for raw land. An office building for a warehouse. A residential rental for a commercial property. All qualify.

Timing rules. The 45-day identification period (from closing on relinquished property) and 180-day exchange period (from closing on relinquished property) apply at the entity level. Treas. Reg. §1.1031(k)-1 governs the safe harbor for deferred exchanges using a qualified intermediary.

Reporting on Form 8824. The entity files Form 8824 with the year’s return, showing the relinquished property details (date acquired, date sold, sales price, adjusted basis) and the replacement property details (date acquired, fair market value, cash received as boot, debt relief). The deferred gain is calculated. The replacement property’s basis equals the relinquished property’s adjusted basis plus boot received minus boot paid plus gain recognized.

Boot. Cash or non-like-kind property received in the exchange triggers recognition to the extent of boot. If the entity exchanges a $2M property with $400K basis for a $1.8M property plus $200K cash, the $200K cash is boot. Recognized gain = lesser of boot received ($200K) or realized gain ($1.6M) = $200K.

Debt relief as boot. Net debt relief (relinquished property debt minus replacement property debt) counts as boot. If the entity exchanges a property with $1.2M of mortgage debt for a property with $900K of mortgage debt, the $300K of net debt relief is boot. Recognized gain to that extent.

Partner-level consequences. The exchange happens at the entity level. Partners’ outside bases adjust by their distributive share of recognized gain (zero if no boot) and by the change in inside basis (replacement property basis). The K-1 reports the exchange as informational, with §704(b) capital account effects.

Partnership distribution issues. Sometimes one or more partners want cash from a partnership exchange while others want to defer. This creates structural challenges because §1031 doesn’t allow partial deferral by partner — the entity either exchanges fully or sells fully. Solutions include drop-and-swap (distributing a TIC interest to a departing partner before exchange) and swap-and-drop (entity exchanges, then distributes interests in the replacement property). Both have IRS scrutiny risk and partnership tax complexity.

Reverse 1031 exchanges. Under Rev. Proc. 2000-37, the entity can acquire the replacement property before selling the relinquished property using an exchange accommodation titleholder (EAT). Same 45-day and 180-day timing applies. The EAT holds title to one property during the exchange period. Form 8824 reports the completed exchange.

Suspended passive losses on exchange. Under §469(g), a §1031 exchange isn’t a fully taxable disposition. Suspended passive losses from the relinquished property carry over to the replacement property. They don’t release. Owners planning to release suspended losses should consider a fully taxable sale instead of an exchange.

Tangible property regulations and Form 8825 reporting

The tangible property regulations (TPR) at Treas. Reg. §1.263(a)-3 govern when repairs deduct as §162 expenses versus capitalize under §263. The analysis applies just as much at the entity level for Form 8825 filers as at the individual level for Schedule E filers.

Three safe harbors. The de minimis safe harbor at Treas. Reg. §1.263(a)-1(f) expenses costs at or below $2,500 per item or invoice ($5,000 for taxpayers with AFS). The routine maintenance safe harbor at §1.263(a)-3(i) expenses recurring activities reasonably expected at placed-in-service date to occur more than once in 10 years. The small taxpayer safe harbor at §1.263(a)-3(h) expenses total annual building spend up to the lesser of 2% of unadjusted basis or $10,000 per building, available to taxpayers with average gross receipts under $10M and buildings under $1M unadjusted basis.

Election mechanics for partnerships and S-corps. The de minimis election must be made at the entity level and attached to the entity return. Same for the small taxpayer safe harbor. Each entity makes its own annual elections.

Reporting on Form 8825. Repairs deductible under §162 (whether direct repairs or items qualifying under safe harbors) report on the repairs line (line 7 of Form 8825). Items capitalized as improvements add to depreciable basis and depreciate on the entity’s depreciation schedule, ultimately flowing to depreciation on line 14.

Partial dispositions. When the entity replaces a major building component (roof, HVAC, electrical system), Treas. Reg. §1.168(i)-8(d) allows a partial disposition election to deduct the remaining adjusted basis of the abandoned old component. The election is made on a timely-filed return. The deduction flows through Form 8825’s depreciation calculations.

Form 3115 method change. Past TPR mistakes (capitalizing repairs or vice versa) can be corrected via Form 3115 method change. The §481(a) catch-up adjustment is included in the entity’s current-year income or deduction. The favorable §481(a) deduction (when prior over-capitalization is reversed) is reported on Form 8825 as a current-year deduction.

Partner-level impact. The §481(a) deduction passes through via K-1. Partners pick it up at their level in the year of the method change.

Audit exposure. The IRS audits TPR compliance frequently in real estate partnerships. The threshold for examination is often a ratio of repair deductions to building basis exceeding 4-6%. Properly classified positions with safe harbor elections, written policies, and documentation defend well. Without these, the IRS recharacterizes.

Coordination with cost segregation. Cost seg studies done at entity level break out building basis by class. When components are replaced and partial disposition elected, the component basis is more readily identifiable. Look-back cost seg studies via Form 3115 capture missed accelerated depreciation. Both can produce material §481(a) deductions.

Real-world example. A 6-property real estate partnership with $14M aggregate building basis spent $185K on building repairs and improvements in 2025. The prior preparer capitalized 70% of it as building improvements. After re-analysis under TPR safe harbors, $148K qualified as deductible repairs (de minimis, routine maintenance, and small taxpayer combined). The remaining $37K stayed capitalized. The change for 2025 increased the entity’s 8825 repair deduction by $148K. Combined with a Form 3115 covering prior years, total §481(a) deduction was $620K. Passed through to partners at average 32% federal rate: $198K of federal tax savings.

Common Form 8825 errors and IRS audit triggers

Error 1: misclassifying repair vs. improvement. Capitalizing routine repairs or expensing improvements. Common when the preparer doesn’t know TPR safe harbors or doesn’t have elections attached to the return.

Error 2: missing depreciation on land improvements. Partnerships often have $30K-$80K of land improvements (parking, fencing, landscaping) that should be 15-year MACRS. Many returns treat them as 27.5/39-year structural. Cost segregation surfaces these.

Error 3: incorrect bonus depreciation election. Bonus depreciation is automatic unless elected out. Some partnerships elect out without realizing the implications. The election must be made class-by-class on Form 4562.

Error 4: wrong residential vs. commercial classification. Mixed-use properties with 80%+ residential rent qualify as residential (27.5-year). Properties just under 80% qualify as commercial (39-year). The classification is per-property and can change year to year if rent mix shifts.

Error 5: missing the §704(b) special allocations. Partnerships with non-pro-rata loss allocations (e.g., promoted GPs getting more depreciation than capital share) must comply with §704(b) substantial economic effect rules. Errors here surface in IRS exams of large partnerships.

Error 6: §163(j) computation errors. The 30% of ATI limit calculation requires careful tracking. Adjusted Taxable Income includes depreciation addback through 2021 (TCJA) but excludes depreciation addback from 2022 forward. The math changed and many preparers missed it.

Error 7: not aggregating real estate activities for §469. A real estate professional individual partner who hasn’t filed the §1.469-9(g) aggregation election can’t combine multiple properties for material participation testing. The election must be on the individual partner’s return.

Error 8: self-rental misreporting. Income from property rented to a related operating business should be recharacterized at the partner level as non-passive (income only). Many returns miss this and treat the income as ordinary passive, losing potential offset against W-2 or business income.

Error 9: §754 election not in place. When a partner dies or transfers interest, §754 election allows basis step-up. Without an existing election, the new owner gets no inside basis adjustment. Missing this on death is a particularly painful mistake — often missed for years.

Error 10: rental activities reported on Form 1065 line 1 instead of Form 8825. Some preparers put rental income directly on line 1 (ordinary business income) when the entity is a real estate operating business with material participation. This misclassifies the income and breaks §469 passive activity tracking. Rental income belongs on 8825 unless the activity rises to the level of dealer in real estate (rare).

Audit triggers. (1) Large losses year over year — the IRS questions economic substance. (2) High repair ratios — 4%+ of building basis flags. (3) Round-number reporting — looks like an estimate. (4) Mismatches between Form 8825 totals and K-1 line 2 allocations across partners. (5) Significant §1031 exchange activity. (6) Material partner distribution patterns suggesting partnership-level distributions vs partner-level loans.

Defensive documentation per property. Keep: rent rolls and 1099-MISC issuance to tenants over thresholds, mortgage statements and Form 1098 for interest, property tax bills, insurance declarations, repair invoices with itemization, capital improvement contracts and engineering reports, cost segregation study, depreciation schedules with prior-year carryovers, partnership agreement with §704(b) allocation rules, partner outside basis schedules, and §469 grouping/aggregation elections. This file lives with the property forever.

Multi-property partnerships and Schedule K-1 coordination

Partnerships with 5+ properties present coordination challenges. Each property is a separate column on Form 8825 (or rolled across multiple Form 8825s for portfolios over 8 properties). Each property has its own depreciation schedule, repair history, and §469 passive activity tracking.

Activity grouping for §469. The default is each property is a separate activity. A real estate professional partner can elect under §1.469-9(g) to aggregate at the individual level. The entity itself can also group activities under §1.469-4 if they form an appropriate economic unit.

Activity-level vs property-level. The IRS regulations distinguish between “activities” (units for §469 testing) and “properties” (physical real estate). One activity might encompass multiple properties (e.g., 6 properties grouped under §1.469-4 as one rental real estate activity). Form 8825 still reports per property; the §469 analysis happens at the activity level.

Schedule K-1 line 2 includes the partner’s distributive share across all properties. The K-1 box 14 or supplemental information typically breaks out by activity if multiple activities exist.

Mixed activities. A partnership might own 4 residential rentals (one activity) and 2 commercial properties leased to related-party tenants (another activity, possibly self-rental). The K-1 reporting separates them. Partners receive Schedule K-1 supplemental information identifying each activity.

Loss limitations stack at partner level. (1) Outside basis limitation under §704(d): can’t deduct losses exceeding outside basis. (2) §465 at-risk limitation: can’t deduct losses exceeding amount at risk (generally outside basis less non-recourse debt). (3) §469 passive activity limitation: rental losses limited unless real estate professional with material participation. (4) §461(l) excess business loss limitation (for non-corporate taxpayers): aggregate business losses limited to $250K single / $500K MFJ in 2026 (inflation-adjusted), excess carried forward as NOL.

Each limit applies in sequence. A partner with $80K of K-1 rental loss who has $90K of outside basis, $70K at risk, and high passive income that can absorb up to $60K of passive losses gets to deduct $60K (limited by §469 first, before §704(d) and §465 even apply).

Capital account maintenance. Partnerships use §704(b) capital accounts to track each partner’s economic stake. The capital accounts must reflect substantial economic effect for special allocations to be respected. Section 8825 depreciation and net income allocations flow through to capital accounts.

Partner liability allocations. Mortgage debt on partnership properties allocates among partners under §752. Recourse debt allocates to partners bearing the economic risk of loss. Nonrecourse debt allocates per the §1.752-3 three-tier waterfall. The allocations affect each partner’s outside basis (Box L of K-1) and §465 at-risk amount.

Sales and exchanges. When a partnership sells a property, the gain or loss flows through to partners via K-1. Capital gain or §1231 gain is reported on K-1 line 9a (net long-term capital gain) or line 10 (net §1231 gain). Depreciation recapture on §1250 property — for real property — is generally taxed at a maximum 25% rate under §1(h)(6). Partner-level reporting on Schedule D and Form 4797.

§704(b) book-tax disparities. Partnerships with non-pro-rata allocations or with property contributed by partners at FMV different from basis maintain book-tax disparities that affect §704(c) allocations. Form 8825 depreciation can be split among partners differently from the entity’s tax depreciation. The Schedule K-1 reports the partner’s tax-basis depreciation share.

S-corporation rental real estate — when 8825 still applies

S-corporations that own rental real estate file Form 8825 just like partnerships. The mechanics differ slightly because S-corps don’t have outside basis tracking as flexible as partnerships and don’t have §704(b) special allocations.

Why S-corps for rental is generally not recommended. Pass-through real estate ownership in S-corp form has significant tax disadvantages compared to partnership/LLC form: (1) No basis step-up on death — IRC §1014 step-up applies but only to the S-corp stock, not the inside building basis. (2) No §754 election available — S-corps can’t elect inside basis step-up on stock transfers. (3) Distributions of appreciated real estate are taxable to the S-corp under §311 — partnerships can distribute without gain recognition. (4) Death of a shareholder triggers basis issues that don’t exist in partnerships.

When S-corps own real estate anyway. Common scenarios: (a) historic conversion before the disadvantages were understood, (b) operating businesses that own their facility, (c) accidental inclusion of real estate in an S-corp that was originally intended for operating activities.

Form 8825 mechanics for S-corps. Identical to partnerships — same form, same lines, same K-1 line 2 flow.

Shareholder loss limits. Shareholders of S-corps are limited to outside basis in stock plus loans they made directly to the corporation. Loans from third parties guaranteed by shareholders don’t count toward basis. This is restrictive compared to partnerships where partner-level recourse debt counts toward outside basis.

Self-employment tax. Rental real estate income passing through an S-corp is generally not subject to self-employment tax (same as partnership rental income on K-1 line 2). The S-corp owner’s reasonable salary requirement applies to active operating income, not to rental real estate passive income.

Reasonable compensation. If the S-corp owner actively manages the rental properties as a real estate professional with material participation, the IRS could argue some compensation is required. The argument is weak for purely passive rental ownership but stronger if the S-corp is paying for property management services through the owner.

Distributions vs. salary. S-corp rental income generally distributes to shareholders without additional tax (it was already taxed at the shareholder level via K-1). No SE tax on the distributions. This is the standard S-corp advantage even with rental real estate.

Exit strategy difficulties. Selling appreciated real estate held in S-corp form triggers gain at the entity level (passing through to shareholders) plus potential built-in gains tax under §1374 if the S-corp was previously a C-corp. The §1374 big tax applies if disposition occurs within 5 years of S-election (formerly 10 years pre-2008).

Drop-down strategies. Some owners create new partnerships and contribute the S-corp’s real estate to the partnership in exchange for a partnership interest. The contribution is generally tax-free under §721 if structured correctly. The S-corp owns a partnership interest instead of real estate directly. Subsequent exchanges and dispositions happen at the partnership level with full §1031 flexibility. The drop-down is structurally cleaner for ongoing real estate operations but has §1374 big tax considerations during the 5-year period.

Practical advice. New real estate ventures should generally use partnership/LLC form, not S-corp. Existing S-corp ownership of real estate should be evaluated for restructuring opportunities, weighing transaction costs against long-term tax efficiency.

Schedule K and K-1 line-by-line for rental real estate

Schedule K of Form 1065 (or Form 1120-S) aggregates the partnership/S-corp’s tax items for distribution to owners. Schedule K-1 is the per-owner detail.

Line 1 — ordinary business income/loss. From Form 1065 line 22. Doesn’t include rental real estate. If your rental property is on Form 8825, it doesn’t appear on line 1.

Line 2 — net rental real estate income/loss. The Form 8825 total flows here. This is where K-1 line 2 originates for partner allocation.

Line 3 — other net rental income/loss. For personal property rentals (equipment rental businesses, vehicle rental businesses). Doesn’t apply to real estate.

Line 4 — guaranteed payments to partners. Subject to SE tax. Doesn’t apply to rental real estate distributions.

Line 5 — interest income. Portfolio income unless converted under §1.469-7 self-charged interest rules.

Line 6 — dividends. Portfolio income.

Line 7 — royalties. Portfolio income.

Line 8 — net short-term capital gain/loss.

Line 9a — net long-term capital gain/loss. Includes gain on partnership-level sales of capital assets.

Line 9b — collectibles 28% gain.

Line 9c — unrecaptured §1250 gain. The maximum 25% rate portion of real property sales.

Line 10 — net §1231 gain/loss. Rental real estate sale gains generally flow here when the property is held for productive use in trade or business or investment.

Line 11 — other income.

Line 12 — §179 deduction. Limited use for real property (only QIP and certain components qualify).

Line 13 — other deductions including contributions, etc.

Line 14 — self-employment earnings/loss. Doesn’t apply to rental income on line 2.

Line 15 — credits.

Line 16 — foreign transactions.

Line 17 — alternative minimum tax items.

Line 18 — tax-exempt income and nondeductible expenses.

Line 19 — distributions.

Line 20 — other information. This is where §469 grouping designations, real estate professional aggregation information, §163(j) limitation amounts, and other supplemental items report.

The K-1’s Item L (capital account analysis) shows beginning capital, contributions, current-year increase/decrease, withdrawals/distributions, and ending capital on tax basis. For Form 8825 entities, the depreciation reduces capital accounts.

Item M shows §704(c) information for built-in gain/loss on contributed property. Real estate contributed to a partnership at FMV different from basis tracks here.

Item N (since 2020) shows the partner’s beginning and ending shares of partnership liabilities — nonrecourse, qualified nonrecourse financing, and recourse. The allocations affect outside basis and §465 at-risk limits.

Year-end planning for Form 8825 partnerships

Year-end tax planning for Form 8825 filers focuses on classification, election timing, depreciation acceleration, and §469 management at the partner level.

1. Repair vs. improvement classification. Review every invoice for the year against TPR safe harbors. Properly classified repairs increase Form 8825 deductions. Annual de minimis and small taxpayer safe harbor elections must be in place.

2. Bonus depreciation timing. With 100% bonus restored for post-1/19/2025 acquisitions under OBBBA, accelerate placed-in-service dates where feasible. A property placed in service December 28 vs. January 5 of next year means a full year of bonus depreciation difference for cost-segregated components.

3. Cost segregation studies. Order studies for properties acquired during the year and for older properties not previously cost-segged. Look-back studies via Form 3115 can capture multiple years of missed accelerated depreciation.

4. Partial disposition elections. When replacing major components (roof, HVAC, etc.), elect partial disposition on the timely-filed return to deduct the remaining basis of the old component.

5. §469 grouping elections. Individual partners who qualify as real estate professionals should file the §1.469-9(g) aggregation election on their individual returns. This combines all rental real estate activities for material participation testing.

6. §163(j) ERPTB election. Evaluate whether the partnership should elect electing real property trade or business status to avoid the 30% of ATI interest limitation. Compare ADS slower depreciation cost vs. interest deduction benefit.

7. Like-kind exchange timing. Properties being sold late in the year and exchanged into replacement property may benefit from delaying the closing into the next year to extend the 180-day exchange window. Alternatively, accelerating into the current year preserves a tax-deferred exchange.

8. Suspended loss release planning. Partners with substantial suspended passive losses on a property should consider a fully taxable sale (rather than §1031 exchange) to release the losses. The released losses can offset ordinary income at the partner level.

9. Outside basis and §754 verification. Confirm §754 election is in place if any partner has died or transferred interest. Outside basis schedules should be updated through year-end for each partner.

10. Reasonable compensation review for S-corps. Confirm S-corp owners with material participation in property management have reasonable compensation for any management services rendered. Pure rental income to passive S-corp owners doesn’t require compensation, but active management does.

11. Form 3115 method changes. Identify any incorrect prior-year treatments that warrant correction. The §481(a) catch-up adjustment is included in the current year. Audit protection benefit on prior years.

12. Estimated tax planning. Partners should estimate their K-1 income/loss before year-end and adjust quarterly estimated payments. Underpayment penalties under §6654 are 8% as of 2026 — material on substantial underpayments.

13. Schedule K-3 and foreign reporting. Partnerships with foreign partners or foreign-source income must file Schedule K-3 with each K-1. Rental real estate held abroad or owned by foreign partners triggers additional reporting. FIRPTA withholding may apply when foreign partners are involved in property sales.

14. Section 199A QBI considerations. Rental real estate may qualify for the §199A 20% qualified business income deduction if the activity rises to the level of a trade or business under Treas. Reg. §1.199A-1(b)(14). Safe harbor under Rev. Proc. 2019-38 requires 250+ hours of rental services per year. The deduction flows from K-1 line 20 codes Z and AA. Each partner evaluates eligibility at the individual return.

15. State apportionment and nexus. Partnerships with properties across multiple states must apportion income for each state. Sometimes nexus considerations require state filings even for partners residing outside the property state. Coordinate with state-level CPAs for multi-state portfolios.

16. Centralized partnership audit regime (BBA). Partnerships filing under the BBA regime (default for partnerships formed since 2018) have new audit rules where adjustments occur at the partnership level. Push-out elections under §6226 transfer the adjustment to partners. Annual evaluation of whether to elect out of BBA (if eligible) is part of year-end planning.

17. Tiered partnership coordination. Partnerships holding partnership interests in lower-tier partnerships (common for real estate fund structures) require careful K-1 coordination. The upper-tier partnership receives K-1s from lower tiers and incorporates the rental income into its Form 8825 (or passes through the character). Timing of lower-tier K-1 delivery affects upper-tier preparation.
