Rental property sits at the intersection of investment income and business income — a unique tax category with its own rules for income reporting, expense deductions, depreciation, passive loss limitations, and eventually capital gains on sale. Understanding these rules helps landlords maximize legitimate deductions and avoid common mistakes that trigger IRS scrutiny.
Reporting Rental Income
All rental income must be reported on Schedule E (Supplemental Income and Loss) of your Form 1040. Rental income includes:
- Monthly rent payments
- Advance rent (rent paid for a future period is income in the year received)
- Security deposits retained at the end of tenancy (refundable deposits are not income until you keep them)
- Payments for canceling a lease
- Services provided by a tenant in lieu of rent (at fair market value)
Rental income is reported in the year it is received, not when it is earned. If your tenant pays January rent in December, it is December income — for the year they paid it.
Deductible Rental Expenses
The list of deductible rental expenses is extensive. You can deduct ordinary and necessary expenses for managing and maintaining the rental property:
- Mortgage interest on the rental property loan (not principal)
- Property taxes (no SALT cap for rental property — the SALT cap only applies to personal taxes)
- Insurance premiums for the rental property
- Repairs and maintenance — fixing a broken window, repainting, plumbing repairs. Must be ordinary maintenance, not improvements.
- Property management fees paid to a management company
- Advertising costs to find tenants
- Professional fees — attorney fees for lease drafting, accountant fees for rental tax preparation
- Travel expenses to visit and manage the property (at the standard mileage rate)
- HOA fees for rental condos
- Utilities paid by landlord
- Depreciation — this is the largest deduction and requires special attention
Improvements are not currently deductible — they are capitalized and depreciated over time. The distinction between a repair (deductible now) and an improvement (capitalized) is one of the most litigated areas in rental tax law. A new roof is generally an improvement; patching an existing roof is a repair.
Depreciation: The Largest Hidden Deduction
Depreciation allows you to deduct the cost of the rental property structure (not land) over 27.5 years using the straight-line method. This is a non-cash deduction — you do not spend any money, but you get a tax deduction every year.
How to calculate annual depreciation:
- Determine the property's cost basis (purchase price plus buying costs)
- Allocate between land value (not depreciable) and structure (depreciable). Typically use property tax assessment ratios to split land vs. building.
- Divide the structure value by 27.5 to get the annual depreciation deduction
Example: You buy a rental property for $350,000 (including closing costs). The land is worth $70,000 based on the assessment. Structure basis = $280,000. Annual depreciation = $280,000 / 27.5 = $10,182 per year. You deduct $10,182 every year without spending any money — it simply reflects the theoretical wear and tear on the building.
Depreciation is one of the most valuable tax benefits of rental ownership. It can turn a cash-flow-positive property into a paper loss for tax purposes — which shelters other income from tax (subject to passive loss rules discussed below).
The Passive Loss Rules: The Biggest Limitation
Rental activities are classified as "passive" by default under the IRS rules, meaning losses from rental properties can generally only offset income from other passive activities — not wages, business income, or investment income.
This means if your rental property generates a tax loss (after depreciation and all deductions), you typically cannot use that loss to reduce your W-2 income in the current year. The loss is "suspended" and carried forward to offset future rental income or to be released when you sell the property.
The $25,000 Allowance Exception
There is an important exception for "active participants" in rental activities. If your modified AGI is under $100,000 and you actively participate in managing the rental (making management decisions, approving tenants, etc.), you can deduct up to $25,000 of rental losses against ordinary income each year. This allowance phases out between $100,000 and $150,000 AGI — above $150,000, no losses can offset ordinary income.
Real Estate Professional Exception
If you qualify as a "real estate professional" under IRS rules — meaning you spend more than 750 hours per year in real estate activities and real estate is your primary profession — rental losses are not passive and can offset any type of income without limit. This status significantly changes the tax math for full-time landlords and real estate investors.
The 20% QBI Deduction for Rental Income
Under the Tax Cuts and Jobs Act, rental income may qualify for the 20% Qualified Business Income (QBI) deduction — reducing your effective tax rate on net rental income. The IRS issued a safe harbor allowing rental activities to qualify as a "trade or business" for QBI purposes if you maintain separate books, keep records, and spend at least 250 hours per year on rental activities. This deduction is currently scheduled to expire after 2025 unless Congress acts — its status for 2026 and beyond depends on legislation.
What Happens When You Sell
Selling a rental property triggers several tax events:
- Capital gain: The difference between your adjusted basis (original cost minus accumulated depreciation) and the selling price, taxed at long-term capital gains rates if held more than a year
- Depreciation recapture: All the depreciation you claimed over the years is "recaptured" and taxed at a maximum rate of 25% — not at favorable long-term capital gains rates
- Release of suspended passive losses: Any passive losses that were suspended from prior years are released and can offset the gain at sale
Many landlords are surprised by depreciation recapture at sale — it can result in a significant tax bill even when the overall gain seems modest. Planning for this in advance (through installment sales or 1031 exchanges) is important.

Short-Term Rentals: Airbnb and VRBO
Short-term rental properties — those rented for an average of 7 days or less per rental — are not classified as passive rental activities under the IRS rules. Instead, they are treated more like an active business, which has significant implications. Losses from short-term rentals are not subject to the passive loss rules and can offset ordinary income — but this also means you may owe self-employment tax on net income, and the property may be classified as a Schedule C business rather than a Schedule E rental.
The tax treatment of short-term rentals is one of the most actively evolving areas of tax law, with the IRS increasingly scrutinizing Airbnb and VRBO income. Keep meticulous records of rental days, personal use days, and all expenses. Days of personal use affect the deductibility of expenses — if you use the property personally for more than 14 days or 10% of rental days (whichever is greater), expense deductibility becomes limited by the personal use percentage.
The 1031 Exchange: Deferring Capital Gains on Sale
When you sell a rental property, a 1031 like-kind exchange allows you to defer capital gains and depreciation recapture taxes by reinvesting the proceeds into another qualifying investment property within strict time limits: 45 days to identify the replacement property and 180 days to close. The taxes are not eliminated — they carry over to the new property's basis — but deferral allows you to redeploy the full pre-tax proceeds into a larger property, effectively using the government's share of your gain as an interest-free loan for continued investment.
