Section 280A Vacation Home Tax: Personal Use Rules, Allocation, and the 14-Day Rule

First, classify under §280A. Then allocate. Then check the short-term rental loophole.

Classification: Rental days: 90 Personal use days: 25 Maintenance days: 8 (excluded from personal use under §280A(d)(2))

Personal use threshold: greater of 14 days OR 10% of rental days = greater of 14 OR 9 = 14.

Personal use of 25 is greater than 14. Category 2: Mixed-use property with significant personal use. Expenses limited to rental income.

Allocation method: Rental days / total used days = 90 / (90 + 25) = 78% rental allocation. (Maintenance days are excluded from both numerator and denominator for the allocation calculation; they’re like vacant days for this purpose.)

Apply 78% to total expenses: – Mortgage interest $12,000 → $9,360 rental allocation – Property tax $5,000 → $3,900 rental allocation – Utilities $3,000 → $2,340 rental allocation – Insurance $1,500 → $1,170 rental allocation – Repairs $2,500 → $1,950 rental allocation – Depreciation $7,500 → $5,850 rental allocation – Total rental expense allocation: $24,570

Rental income: let’s say $40,000.

Net rental income before §280A limit: $40,000 − $24,570 = $15,430.

Is Category 2 limit applicable here? Yes, but the limit only restricts loss generation. Since you have positive net rental income ($15,430), no limit applies. You report $15,430 of rental income on Schedule E.

If rental income were instead $20,000 with the same $24,570 expenses, net would be −$4,570. Under §280A(c)(5), rental expenses are capped at rental income ($20,000). The remaining $4,570 of unused expenses (mostly depreciation) carries forward as a §280A carryover, usable in future years against rental income from this property.

Now check the short-term rental loophole: Airbnb rentals typically have stays of 1-7 nights. If your average stay is 7 days or fewer, the property might qualify for nonpassive treatment under §469(c)(7) and Reg §1.469-5T(a). This applies when: – Average rental period is 7 days or fewer – You materially participate in the rental activity

Material participation tests under §469(h): – 500 hours of participation in the activity per year, OR – 100+ hours AND more than any other person, OR – Substantially all participation

For a Cape Cod Airbnb host doing all marketing, communication, booking management, cleaning coordination, maintenance, and guest support, hitting 100+ hours is realistic. 500 hours is a stretch but possible for someone heavily managing the property.

If you qualify as materially participating in a short-term rental: – The property is nonpassive – Losses (if any) are deductible against W-2 wages or other active income – §280A still applies for personal use allocation – You don’t need to be a real estate professional under §469(c)(7) (the qualification path is narrower for STR)

For your $15,430 of net rental income, the short-term rental loophole doesn’t change much (you have positive income, not loss). But in years with losses (high expenses, low rental income), the loophole would let you deduct losses against W-2 wages, which is meaningful.

The other tax point: should you separately characterize this as a ‘trade or business’ under §162 vs. §280A rental? If you provide substantial services beyond standard rental (concierge, daily cleaning, meals, transportation), the activity becomes a hotel-like trade or business. The income then is self-employment income subject to SE tax (15.3% on the first ~$170K). For most standard Airbnb hosts who don’t provide hotel-level services, this isn’t the right characterization.

State tax: Massachusetts taxes vacation rental income at ordinary income rates. State allocation follows the §280A allocation framework — 78% of expenses against the rental income. Net rental income state-taxed at MA rate (5% flat).

Forms to file: – Schedule E for rental income/expenses – Form 4562 for depreciation – Form 8582 if losses (passive activity tracking) — likely N/A in your profit year – 1099-K from Airbnb (matched to Schedule E income) – Documentation: rental calendar with day-by-day breakdown, expense receipts, maintenance log

My recommendation: report the $15,430 net rental income for 2026. Also explicitly track your hours managing the property in case you have a loss year or want to claim active participation status. If 2027 has losses, the active participation classification could save significant tax.

Depends on whether you’re charging fair market value and whether the renters are family.

The 14-day rule (§280A(g), often called the Augusta Rule) excludes rental income from gross income if total rental days are 14 or fewer in the year. The rule applies regardless of who the renters are — could be family, friends, business associates, total strangers.

BUT, the §280A(d) personal use definition counts use by family members as personal use, REGARDLESS of payment. So if your sister stays 4 days at your Tahoe condo paying full market rate, those 4 days count as personal use TO you. They don’t count as rental days for purposes of the 14-day rule.

Family for §280A(d) purposes: spouse, children, grandchildren, parents, grandparents, brothers, sisters. (Note: not in-laws, not cousins, not aunts/uncles.)

For ‘friends of family’ or actual friends paying market rate: these are arm’s-length rentals, not personal use. They count as rental days for the 14-day rule.

Let me re-read your scenario: ‘8 days a year to family of friends during their ski trips.’ I read ‘family of friends’ as ‘families of your friends’ (e.g., your friend Bob and his wife/kids), not ‘your family of friends’ (your relatives). If correct interpretation: these are arm’s-length friends paying for use, not §280A(d) family members.

Under that interpretation: – Total rental days: 8 – 14-day rule applies (8 ≤ 14) – Rental income from these 8 days is excluded from gross income – Tax-free

Document the arrangement: – Written rental agreement for each stay – Fair market rental rate documented (compare to local short-term rentals) – Payment received – Clear that the renters are not your spouse/children/parents/siblings

If the ‘family of friends’ are actually your relatives (e.g., your cousin’s family), then those days are personal use and the 14-day rule doesn’t include them as rental days. You’d have: – Rental days: 0 (relatives don’t count as rental) – Personal use days: 8 (your relatives staying) – No rental income to report – No 14-day rule application (no rental at all)

One edge case: if you do rent to your immediate family but charge fair market value AND treat the rental as commercial (you’ve structured it as a business with normal arms-length terms), there have been Tax Court cases addressing this. The IRS position is conservative: family payment doesn’t make it ‘rental’; it’s still personal use under §280A(d). The Tax Court has upheld this in most cases.

If you ALSO rent the condo to non-family for additional days in the year, count all rental days together. If total rental days (non-family only) is 14 or fewer, the 14-day rule still applies. If you rent to non-family for 10 days AND to family for 5 days, the 5 family days are personal use, the 10 non-family days are rental, 14-day rule applies (10 ≤ 14), and the non-family rental income is tax-free.

For your Tahoe scenario at 8 rental days to non-family friends: $0 reported income, $0 deduction, tax-free. Simple.

For recordkeeping: maintain the rental agreements and payment records even though you’re not reporting the income. The IRS may inquire if their information matching shows discrepancies (e.g., if your friends pay via a payment platform that issues 1099-K, the platform reports to IRS but you don’t report the income — the IRS may question why). The 14-day rule defense is valid, but you need to document.

State tax: Nevada has no state income tax, so even if §280A didn’t apply, no state tax on rental income. (California taxes vacation rental income for residents; if you’re CA-resident but property is in NV, the rental income would be NV-source. Nonresident CA tax doesn’t apply to NV-source income.)

Local: Tahoe area has transient occupancy tax (TOT) imposed by local jurisdictions. This applies to short-term rentals even under 14 days. Check your county’s TOT obligations — they’re separate from federal/state income tax and not eliminated by §280A(g).

You’re in Category 2 (mixed-use with significant personal use), and the math creates a situation many Hamptons owners face: substantial rental income but no current deduction beyond the rental income.

Classification: – Rental days: 60 – Personal use: 18 – Personal use threshold: greater of 14 OR 10% × 60 = greater of 14 OR 6 = 14 – 18 > 14, so Category 2 applies

Allocation: – Rental days / total used days = 60 / (60 + 18) = 77% rental

Assumed expenses for a $2.4M Hamptons house (some figures plausible): – Mortgage interest (on $1.5M mortgage at 6.5%): $97,500 – Property tax: $35,000 (Hamptons high tax burden) – Utilities, insurance, maintenance: $18,000 – Depreciation (on $1.8M building basis): $65,455 – Pool, landscaping, fees: $25,000 – Repairs: $10,000 – Total expenses: $250,955

Rental allocation: 77% × $250,955 = $193,235.

Rental income: $30,000.

Net rental income before §280A limit: $30,000 − $193,235 = −$163,235 (massive loss on paper).

Apply §280A(c)(5) limit: rental expenses capped at rental income. $30,000 of expenses allowed. The remaining $163,235 of disallowed expenses carries forward as a §280A carryover.

Ordering matters here. Under section 280A(c)(5) the deductions come off rental income in a set sequence, mortgage interest and property tax first, then operating expenses, then depreciation. Start with the interest and tax allocable to the rental, which would be deductible on Schedule A anyway. Add the $97,500 of mortgage interest and the $35,000 of property tax for $132,500, then take the 77 percent rental share, which is $102,025. That figure alone already tops the $30,000 of rental income, so the section 280A limit bites right at the mortgage interest line.

Reportable on Schedule E: $30,000 of rental income, $30,000 of rental expense (mortgage interest portion). Net rental income: $0.

The other $72,025 of allocated mortgage interest and property tax cannot run through Schedule E this year. The personal share of mortgage interest and property tax already sits on Schedule A. The rental share that section 280A(c)(5) disallows is not lost. It carries forward and offsets rental income from this property in future years.

Personal allocation of mortgage interest and property tax: 23% × $132,500 = $30,475. This goes to Schedule A as personal-residence mortgage interest and property tax (subject to the $10K SALT cap and $750K mortgage cap).

Let’s summarize: – Schedule E: $30K rental income − $30K rental expense (mortgage interest) = $0 net – Schedule A (personal portion): $30,475 of mortgage interest + property tax (subject to caps) – §280A carryforward: $163,235 of unused rental expense (mostly mortgage interest, property tax, depreciation) carries to future years – Operating expenses, utilities, depreciation: all unused this year (capped by §280A); all carryforward

This is the pain of high-end Hamptons rental in Category 2. You have $250K of property-related expenses, $30K of rental income, and no current loss deduction. The §280A carryforward grows year by year. At eventual sale, the carryforward effectively reduces the embedded gain, but you don’t get year-by-year deductions.

Ways out:

1. Reduce personal use. Drop from 18 days to 14 days or fewer, and you’d be in Category 3. As Category 3 with 14 days personal use and 60 rental days, threshold is greater of 14 or 6 = 14, and personal use is 14 (not greater). Category 3 applies. Then rental losses are deductible (subject to §469 passive activity rules). For high-income Hamptons owner (probably above $150K AGI), the $25K special allowance doesn’t apply. Losses are suspended as passive losses unless you qualify as real estate professional.

2. Real estate professional status (§469(c)(7)): requires more than 750 hours and more than 50% of personal services in real property trades or businesses. For a Hamptons owner with a day job, this is rarely achievable. If your spouse is a real estate professional, the loss could become deductible against W-2 wages.

3. Short-term rental loophole. If your rentals are short stays (under 7 days average) and you materially participate, the property is nonpassive. Even with Category 2 limitation (still applies — §280A overlay), you can use losses against ordinary income subject to the §280A cap. Doesn’t change the §280A loss limitation but does change the passive activity character.

4. Increase rental days. If you rent 120 days instead of 60, and keep personal use to 14 days (now 14 vs. 10% × 120 = 12; 14 is greater than 12, so still Category 2). Or 130 days, then 14 vs. 13 = 14, still Category 2. To get to Category 3 with 14 personal use days, you’d need 140+ rental days (10% × 140 = 14, and personal use 14 not greater). Hard to achieve in Hamptons with high seasonal demand.

My recommendation: reduce personal use to 14 days max. This isn’t always emotionally feasible (you want to enjoy your Hamptons house), but financially it changes the deduction picture significantly.

If you must keep 18+ days personal use, accept the §280A carryforward and plan for eventual recovery at sale. The carryforward releases on disposition of the property in a fully taxable transaction.

For exit planning: when you eventually sell the Hamptons house, the accumulated §280A carryforward reduces the sale gain. Plus you’ll have §1250 depreciation recapture on whatever depreciation you did claim. And the §121 exclusion (principal residence) doesn’t apply unless you’ve used it as principal residence 2 of last 5 years. Run a sale projection 12-24 months before any contemplated transaction.

Yes, with proper documentation. The Augusta Rule (technically §280A(g) — the 14-day rule) allows you to rent your personal residence to your S-corp for up to 14 days per year, with the rental income tax-free to you AND the rent payment deductible by the S-corp.

For 5 days of off-site retreat use, you’re well within the 14-day annual limit. Mechanics:

Step 1: Establish a rental agreement. Written contract between you (as homeowner) and the S-corp (as renter). Contract should specify: – Property address – Rental period (specific dates) – Daily rental rate – Total rental amount – Permitted use (business retreat, meetings, etc.) – Signed by both parties (as homeowner, sign personally; as S-corp officer, sign on behalf of S-corp)

Step 2: Document fair market value. The rent must be reasonable for comparable use of similar property. Common proxies: – Hotel conference room rates in your area for similar groups – Short-term rental rates for similar homes (Airbnb, VRBO comparables) – Hotel meeting space rates with catering and amenities

For a typical S-corp retreat (10-15 people, 5 days, meals included), the comparable rate might run $1,500-$3,000/day. Total $7,500-$15,000 for 5 days. The IRS will scrutinize rates much higher than this without supporting documentation.

Step 3: Document business purpose. Each rental day should have substantial business activity: – Meeting agenda for each day – Attendees (employees, contractors, advisors) – Meeting minutes or notes – Topics discussed – Business decisions made

This is the part most often missing. A retreat that’s ‘team building’ with no documented business agenda invites disallowance. Real business activity is needed: planning sessions, strategy meetings, training, sales meetings, etc.

Step 4: Process the payment. S-corp writes a check to you for the rental amount. You deposit it. The transaction should be recorded in S-corp books as ‘Office Space Rental’ or ‘Conference Facility’ — separate from owner’s draw or salary.

Step 5: Tax reporting: – For you personally: rental income from 5 days of rental is excluded from gross income under §280A(g). You don’t report it on your personal return. No deduction taken (because no income reported). – For S-corp: the rent paid is a deductible business expense on Form 1120-S. Reported as rent expense.

Result: $15,000 of rent paid by S-corp reduces S-corp taxable income by $15,000 (saving ~22-37% federal + state tax, depending on the S-corp shareholder’s bracket — passes through to your personal return). You receive $15,000 of tax-free cash. Combined tax savings on the rent deduction: roughly $5K-$6K for a high-bracket business owner. Net win.

What the IRS scrutinizes:

1. Sham arrangements. Renting your home for $50,000/day for a ‘business meeting’ that’s really a personal weekend with the family at the lake house — disallowed immediately on audit.

2. Inflated rent. Renting at $5,000/day when comparable rates are $1,000/day — partial disallowance. The IRS will allow the reasonable rate and disallow the excess as a constructive dividend or compensation.

3. Pure personal use disguised as business. If the ‘meeting’ was really just employees relaxing at your house with no documented business purpose, the IRS recharacterizes the rent as personal expense or constructive distribution.

4. Bundled use. If you also stayed at the house during the ‘rental period’ (e.g., you slept there during the 5-day retreat), the days are mixed-use. The IRS may allow the business portion of the rent for the days, but the personal-use portion may be problematic.

Best practice for clean documentation:

– Clear written rental agreement signed before the rental period starts – Detailed meeting agenda for each day – Attendance log – Written meeting minutes – Sign-in sheets – Photos of the working space set up for meetings (not photos of beach lounging) – Itemized rental rate justified with 3-5 comparable property/hotel rates – Bank statements showing S-corp paid you the rent amount – S-corp books showing rent expense, not owner distribution

For 5-day retreat at $2,500/day = $12,500: – S-corp deducts $12,500 (saves ~37% × $12,500 = $4,600 federal tax, plus state) – You receive $12,500 tax-free – Net win: about $4,600-$5,500 of tax savings, depending on S-corp/shareholder situation

Do this annually (within the 14-day limit) and you can generate $50K-$200K of tax-free income to yourself over the life of the S-corp, with corresponding business deductions.

Don’t stretch the rule. The Augusta Rule is well-respected and clean when documented properly. Aggressive variations (rates that don’t match market, days without genuine business purpose, family vacations rebranded as ‘retreats’) get challenged and disallowed.

Our Augusta Rule guide covers more detailed documentation templates and edge cases.

Big shift in tax treatment when you convert from rental property to primary residence. Here is what changes.

Current situation (rental property under §280A): – Rented 100 days/year on Airbnb – Assume personal use under threshold (you live elsewhere) – Category 3: standard rental property – Rental income on Schedule E, expenses allocated to rental percentage, depreciation claimed annually – Passive activity loss rules apply (probably suspended losses given Vermont costs)

After conversion to primary residence: – Stop renting (or rent under 14 days/year to qualify for §280A(g)) – Property is now personal residence – Mortgage interest and property tax deductible on Schedule A (subject to SALT cap and mortgage interest cap) – Depreciation stops as of conversion date – No more Schedule E reporting (assuming you stop renting)

Key tax events at conversion:

1. Recapture concerns. There’s no immediate depreciation recapture event at the conversion (rental to personal use is not a ‘disposition’). But the accumulated depreciation sits in your basis history. At eventual sale, §1250 recapture on accumulated depreciation applies (up to 25% federal rate on the depreciation portion of gain), regardless of intervening personal use.

2. Suspended passive activity losses. If you had Form 8582 suspended losses from prior rental years, these stay suspended. They don’t release at conversion to personal use (it’s not a ‘disposition’ under §469(g)). They wait for actual disposition of the property (sale, exchange, etc.).

3. §121 principal residence exclusion. Once you’ve used the property as principal residence for 2 of the prior 5 years, you can use the §121 exclusion at sale ($250K single / $500K MFJ).

But §121(b)(5) limits the exclusion based on ‘nonqualified use’ periods. Time used as rental (not principal residence) before conversion is ‘nonqualified use’ that reduces the exclusion.

Math: §121(b)(5) reduces the excluded amount by the ratio of nonqualified use years to total ownership years. If you owned the home for 10 years total, used as rental for 5 years before conversion, then as principal residence for 5 years, the nonqualified use fraction is 5/10 = 50%. The §121 exclusion is reduced by 50%.

MFJ couple: full §121 exclusion is $500K. After 50% reduction: $250K. The first $250K of gain is excluded, the rest is taxable.

Plus §1250 recapture on the depreciation: even with §121 partial exclusion, the recapture on accumulated depreciation is fully taxable (not excludable).

Example at hypothetical sale 5 years post-conversion: – Original purchase: $400K (2018) – Total ownership: 10 years (2018-2028) – Used as rental: 2018-2023 (5 years) – Converted to principal residence: 2023 – Used as principal residence: 2023-2028 (5 years) – Depreciation claimed during rental period: $50K – Sale price 2028: $700K

Calculating gain: – Sale price: $700,000 – Adjusted basis: $400K + improvements – $50K depreciation = $350K (assume no improvements added) – Total gain: $350K – §1250 recapture on $50K depreciation: $50K at 25% rate = $12,500 (federal) – Remaining gain: $300K – Nonqualified use fraction: 5 years rental / 10 years total = 50% – §121 exclusion: $500K × (1 – 50%) = $250K – Excluded gain: $250K – Taxable LTCG: $300K – $250K = $50K at 20% = $10,000 – Total federal tax: $12,500 + $10,000 = $22,500 – Plus NIIT 3.8% on most of the gain (about $5K) – Plus Vermont state tax (~6% on portion)

Without the §121 exclusion (if you sold while still rental property): $350K gain × 23.8% federal + state = ~$95K total tax.

With partial §121: $22,500 + state ≈ $40K-$50K total. Saves ~$45K-$55K vs. straight rental sale.

More valuable §121 if you’d been principal residence longer: if 8 years principal residence and 2 rental, nonqualified use fraction is 2/10 = 20%. §121 exclusion is $500K × (1 – 20%) = $400K. Much more gain excluded.

The planning: convert sooner and stay longer to make the most of the §121 benefit.

2. Tax planning around the conversion year:

Last year of rental (year of conversion): partial year of rental income + partial year personal use. Allocate the year correctly between rental treatment (Schedule E with depreciation through conversion date) and personal residence treatment (starting at conversion date).

First year of personal residence: Schedule A picks up mortgage interest and property tax for the full year (the personal-use portion was already on Schedule A in rental years; now it’s the full amount).

3. State tax: Vermont state income tax (~6%). Rental income was taxed at VT rates; personal residence doesn’t produce taxable income. Property tax is high in VT (~2-3% of value) and continues to apply.

4. Other considerations:

– Insurance: switch from rental property insurance to homeowner’s insurance. Lower cost typically. – Mortgage: confirm with lender that your mortgage allows conversion to primary residence (most do). – Capital improvements: improvements after conversion go to personal residence basis (added at FMV after conversion, depreciable only if you rent it again).

My recommendation: if you’re seriously planning to move and the timing works, convert as soon as practical. Each year of principal residence use (post-conversion) tilts the §121 exclusion ratio more in your favor. The total tax savings at sale can be substantial — $40K-$80K depending on appreciation.

Document the conversion clearly: date of conversion, switch to Vermont driver’s license, voter registration, primary residence on tax returns going forward. The IRS will look at this if questioned later.

If you might move back or convert again to rental: keep records of usage years carefully. Multiple conversions in and out create complicated §121 calculations.

For your specific case, talk to a CPA about timing — particularly whether to convert mid-year (creating a hybrid year) or wait until January 1 (clean year). The choice depends on your specific income and rental patterns.
