Rental property tax basics: depreciation, passive losses, and how the math works

Depreciation often shelters all of your rental income tax-free — but §469 passive loss rules limit what you can deduct against W-2 income. Here’s how it works.

Rental real estate has the most powerful tax structure of any mainstream investment. Depreciation creates paper losses that typically shelter all of your rental income from tax — and sometimes a chunk of your W-2 income too. But Section 469’s passive activity loss rules decide whether those losses actually hit your tax return now or get suspended for years.

This guide is the foundation. Once you’re past the basics, see the deeper guides on Real Estate Professional Status (REPS), the short-term rental loophole, and 1031 exchanges.

This is a guide, not tax advice. Once you own more than one rental, hire a CPA who actually does real estate. The fees are tiny relative to the savings.

Schedule E: where rentals live on your return

Long-term rental activity is reported on Schedule E (Form 1040, Supplemental Income and Loss). Each property gets its own column:

  • Gross rents collected
  • Operating expenses:
    • Property tax
    • Insurance
    • Mortgage interest
    • Repairs and maintenance
    • Supplies
    • Utilities (if landlord-paid)
    • Property management fees
    • Advertising
    • Professional fees (legal, accounting, leasing)
    • HOA dues
    • Travel to/from the property (within reason)
  • Depreciation (the big one)
  • Net rental income or (loss)

That last line flows to your 1040, subject to the passive loss rules discussed below.

A few things that LOOK like expenses but aren’t:

  • Capital improvements (new roof, full kitchen remodel, addition): capitalized and depreciated, not expensed.
  • Mortgage principal: not an expense; it’s debt repayment.
  • Your own labor: never deductible. You can’t pay yourself for fixing the toilet.

Depreciation 101

The IRS lets you deduct the cost of a rental building over its useful life, even though the building isn’t actually losing value (usually it’s appreciating). This is the magic.

  • Building only. Land does not depreciate — you have to back out the land value first.
  • Residential rental: 27.5-year straight-line (~3.636% of building basis per year).
  • Commercial real estate: 39-year straight-line.
  • Mid-month convention in the year of acquisition and disposition (you don’t get a full year if you bought in November).

Land allocation

Typical land allocation: 20–30% of purchase price, varying by property and market. High-density urban properties might run 30–40%; rural land-rich parcels can hit 50%+.

How to nail it down:

  • County tax assessor card: shows assessed building vs. land. Ratio is usually defensible if it’s the only documentation you have.
  • Independent appraiser: more authoritative; useful for higher-end properties or anything close to an audit threshold.
  • Insurance replacement cost: a rough proxy for the building number.

A land allocation that’s suspiciously low (under 15%) is an audit flag. Don’t play games here.

Worked example

You buy a single-family rental for $400,000. County card shows 75% improvement, 25% land.

  • Building basis: $400,000 × 0.75 = $300,000
  • Annual depreciation: $300,000 ÷ 27.5 = $10,909/yr

For 27.5 years (until basis is fully depreciated), you take a $10,909 non-cash deduction every year against rental income.

Cost segregation (the advanced strategy)

A cost segregation study is an engineering analysis that reclassifies portions of the building into shorter-lived asset classes:

  • 5-year property: carpet, appliances, certain fixtures
  • 7-year property: removable cabinetry, certain furniture
  • 15-year property: land improvements (driveway, landscaping, fencing, parking lot)

Instead of depreciating the whole building over 27.5 years, you’re depreciating ~20–30% of it over 5/7/15 years. Bonus depreciation then lets you take a large chunk in year one.

Bonus depreciation schedule

The One Big Beautiful Bill Act (OBBBA, signed July 2025) restored 100% bonus depreciation permanently for property acquired AND placed in service after Jan 19, 2025. Property under a binding contract before that date follows the old TCJA phase-down (40% in 2025, 20% in 2026):

  • 2017–2022: 100%
  • 2023: 80%
  • 2024: 60%
  • 2025 pre-Jan 19 / under prior contract: 40%
  • 2025 post-Jan 19 / 2026+ acquisitions: 100% (OBBBA, permanent)

Multiple bills in Congress have proposed restoring 100% bonus depreciation retroactively or going forward. Provisions in some 2025 tax legislation may have already changed the 2025 and 2026 numbers. Confirm the percentage in effect on your placed-in-service date with a CPA before claiming bonus — this is the single biggest moving target in cost segregation right now.

When cost seg makes sense

Rough rule of thumb: building basis above $500k. Study cost runs $5,000–$15,000. The first-year tax deferral typically returns 5–10× the study cost, but the benefit is deferral, not permanent savings — you’re front-loading deductions you would have taken anyway.

The recapture trap on exit

When you sell, all that accelerated depreciation comes home:

  • The building portion (1250 property) recaptures as unrecaptured Section 1250 gain, capped at 25% federal.
  • The 5/7/15-year personal property portion (1245 property) recaptures as fully ordinary income — up to 37% federal, no 25% cap.

Cost seg is a powerful timing strategy, but the back-end pain is real. A 1031 exchange can defer the recapture (see 1031 exchange guide). Don’t do cost seg without modeling the exit.

Section 469 passive activity loss rules

Here’s where most of the tax planning happens.

Under §469, rental real estate is per se passive — classified as passive regardless of how much time you spend on it. There are two exceptions, covered below.

The default rule

Passive losses can only offset passive income. They CANNOT offset:

  • W-2 wages
  • Self-employment income (active business)
  • Portfolio income (interest, dividends, most cap gains)

If your rental shows a $20k paper loss and you have no other passive income, that $20k is suspended — carried forward indefinitely. It doesn’t disappear; it just waits.

Suspended losses are released in two situations:

  • You generate passive income in a future year (the carried losses offset it).
  • You fully dispose of the activity in a taxable transaction (sell the property to an unrelated party). Under §469(g), all accumulated suspended losses release at once and offset any income — W-2, portfolio, the gain on the sale itself. This is the “release valve” that makes long-held passive positions tolerable. Note: a 1031 exchange is NOT a fully taxable disposition; suspended losses stay suspended, attached to the replacement property.

The $25,000 active participation allowance (§469(i))

Congress carved out an exception for small landlords. If you actively participate — “meaningful management decisions” like approving tenants, setting rental terms, approving capital expenditures (a much lower bar than material participation) — AND you own at least 10% of the activity by value, you can deduct up to $25,000 of rental losses against W-2 and other active income. Married filing separately gets HALF ($12,500), and only if you lived apart all year — otherwise zero.

The catch: it phases out by modified AGI (MAGI — AGI without the rental loss itself):

  • MAGI ≤ $100,000: full $25,000 allowance
  • MAGI $100,000–$150,000: phases out 50¢ per dollar of MAGI over $100k
  • MAGI ≥ $150,000: zero allowance; losses fully suspended

The thresholds are NOT inflation-adjusted — they’ve been $100k/$150k since 1986. MFS halves them to $50k/$75k (and only if you lived apart all year). This means a household making $200k+ in W-2 income gets no special allowance — they need REPS or the STR loophole to use rental losses currently.

Real Estate Professional Status (REPS)

REPS sidesteps the per-se-passive classification entirely. To qualify, you (or one spouse on a joint return) must:

  • Spend >750 hours per year in real property trades or businesses, AND
  • Spend >50% of your total personal services in real property trades or businesses

PLUS materially participate in each rental (or aggregate them with the §1.469-9(g) election).

REPS is the holy grail for high-W-2 households with rentals. It’s also heavily audited. Full guide: Real Estate Professional Status (REPS). Use the REPS calculator to test your hours.

The short-term rental “loophole”

Properties with average guest stay of 7 days or less are NOT classified as rental activities under §1.469-1T(e)(3)(ii) of the regulations. They’re treated like a hotel-style business.

Why this matters: the per-se-passive rule for rentals doesn’t apply. Instead, the standard material participation tests apply — typically the 100-hour-and-more-than-anyone-else test or the 500-hour test. Pass material participation, and the losses are non-passive. That means they offset W-2 income without REPS.

This is why so many high-income professionals (doctors, lawyers, tech workers) buy short-term rentals: a manageable hour count (~100–200/yr) unlocks meaningful tax shelter against very large W-2 income, with no REPS requirement.

Full mechanics in the short-term rental investing guide and the STR calculator.

The numbers in practice

Single-family rental example.

  • Purchase price: $400,000
  • Land allocation: 25% → building basis $300,000
  • Depreciation: $10,909/yr
  • Gross rent: $3,000/mo → $36,000/yr
  • Operating expenses: $14,000/yr (tax, insurance, repairs, mgmt, etc.)
  • Mortgage interest: $20,000/yr (year 1, $300k loan at ~6.5%)

Schedule E:

  • $36,000 (rent)
  • − $14,000 (op ex)
  • − $20,000 (interest)
  • − $10,909 (depreciation)
  • = −$8,909 paper loss

Note the property is probably cash-flow positive (~$2k/yr after debt service) — the loss is entirely the depreciation.

How that loss flows depending on your situation:

  • W-2 high earner, AGI $200k, no REPS, no STR: loss SUSPENDED. Zero current benefit; carries forward.
  • W-2 earner, AGI $80k, active participant: loss FULLY DEDUCTIBLE under the $25k allowance. AGI under $100k, plenty of room.
  • W-2 earner, AGI $130k, active participant: 50% phased out; can deduct up to $10,000 of the loss.
  • REPS-qualified household: loss FULLY DEDUCTIBLE regardless of AGI.
  • STR with material participation (avg stay <7 days, 100+ hr personal participation): loss FULLY DEDUCTIBLE regardless of AGI.

Tax savings math

Once a loss is deductible, the cash savings are simply:

Deductible loss × marginal rate = tax saved

For the $8,909 loss at a 24% federal marginal: $2,138 in federal tax saved, plus state if applicable. At the 32% bracket: $2,851. At the 37% bracket: $3,296. Stack a few properties and the numbers get serious fast.

The exit (sale)

The bill comes due when you sell. Two pieces of gain to track:

Depreciation recapture

All depreciation taken or “allowable” gets recaptured. The allowed-or-allowable rule is critical: even if you skipped depreciation for years, the IRS still treats you as having taken it for recapture purposes. You don’t save on recapture by skipping — you just lose the deductions you should have had.

For real estate, this is unrecaptured §1250 gain, taxed at your ordinary rate but capped at 25% federal. Personal property reclassified via cost seg (5/7/15-year property) is §1245 and recaptures as fully ordinary — no 25% cap.

Capital gain on top

Anything above your adjusted basis (after recapture is handled) is long-term capital gain at 0%/15%/20% federal, plus 3.8% NIIT above income thresholds, plus state.

Worked example

You bought the $400k rental and depreciated $109k of building basis over 10 years. Adjusted basis = $400k original cost − $109k depreciation = $291k (building basis is now $191k, plus $100k of non-depreciable land). You sell for $550k net of selling costs.

Rough math:

  • Total gain: $550k − $291k (adjusted basis) = $259k
  • Of that, $109k is unrecaptured §1250 gain (depreciation recapture) at the lesser of 25% or your ordinary rate = up to $27,250
  • Remaining $150k is LTCG at 15% = $22,500
  • NIIT 3.8% on the $259k investment gain (if MAGI thresholds met) = ~$9,800
  • Plus state

Total federal-only: ~$60,000 on a $259k gain. Higher with cost-seg §1245 recapture (taxed at full ordinary rates — no 25% cap) or state tax.

The 1031 exchange

A properly executed 1031 like-kind exchange defers all of this into a replacement property. No depreciation recapture, no cap gains tax — the deferred gain rolls into the new property’s basis.

OBBBA (July 2025) and what it changed

The One Big Beautiful Bill Act averted the TCJA sunset and made several major rental-tax provisions permanent:

  • Bonus depreciation: restored to 100% permanently for property acquired and placed in service after Jan 19, 2025 (above)
  • §199A QBI deduction: made permanent (no longer sunsets after 2025). Up to 20% deduction on qualified rental income; see the QBI for rentals guide
  • Excess business loss limitation (§461(l)) caps non-passive business losses (including REPS / STR losses) at $305k single / $610k MFJ for 2024 (inflation-adjusted; verify current year). Excess becomes an NOL carryforward. OBBBA made this cap permanent too.

Confirm the law in effect for your tax year before relying on any specific number.

Common mistakes

  • Not depreciating. You owe recapture on depreciation that was “allowed or allowable” even if you didn’t actually take it. Always depreciate.
  • Wrong land allocation. 20–30% is the typical defensible range. Suspiciously low allocations (5–10% land) get flagged. Use the county card or get an appraiser.
  • Forgetting the $25k allowance phases out by $150k AGI. High-W-2 earners get nothing without REPS or STR.
  • Buying STRs without checking material participation. The loophole only works if YOU materially participate. Outsourcing everything to a property manager kills it.
  • Doing cost segregation without modeling the exit. Front-loaded benefit, back-loaded ordinary-rate recapture. Beautiful if you 1031; painful if you sell taxable.
  • Mixing personal and rental expenses. Use a separate bank account and credit card per property from day one.
  • Not using a CPA when you’re serious. The fees are $1,500–$5,000/yr. The savings are routinely 5–50× that.
