Real Estate Tax CalcRental losses are passive by default
Under IRC Section 469, rental activities are per se passive for most taxpayers. Passive losses can only offset passive income — generally income from other rental properties or passive business interests. They cannot directly offset wages, salary, or interest income. This means a W-2 employee who owns a rental and shows a $20,000 tax loss on Schedule E typically cannot deduct that loss against their paycheck in the current year. It is suspended and carries forward.
There are three ways out of this limitation, in order of increasing difficulty.
Path 1: the $25,000 active-participation allowance
If you actively participate in your rental (you make management decisions — approving tenants, deciding on repairs, setting rents — even if a manager handles day-to-day tasks), you may deduct up to $25,000 of rental losses per year against non-passive income. This allowance phases out between $100,000 and $150,000 of modified AGI — at $100,000 you get the full $25,000, at $125,000 you get $12,500, at $150,000 or above you get nothing.
Most moderate-income W-2 landlords with one or two properties qualify for this allowance. It is the most accessible path.
Paths 2 and 3: REPS and short-term rentals
Real Estate Professional Status (REPS) under Section 469(c)(7) removes the passive designation entirely for real estate activities if you spend more than 750 hours per year in real estate and real estate constitutes more than 50% of your total personal service hours. For a full-time W-2 employee who works 2,000 hours per year, qualifying for REPS means spending more than 2,000 hours in real estate — essentially impossible while employed full-time. REPS is primarily available to a non-working spouse.
Short-term rentals (average rental period of seven days or less) are not classified as rental activities under IRC 469 — they are treated as a business. If you materially participate in the STR activity (the simplest test is 500+ hours per year), the losses are non-passive and deduct against W-2 income with no MAGI phase-out.
A worked example across income levels
The $25,000 allowance is only as useful as your income allows, so run the numbers before counting on it. Suppose you have a $22,000 rental loss and actively participate. At a modified AGI of $95,000, the full $25,000 allowance is available and the entire $22,000 loss offsets your W-2 income this year — at a 22% marginal rate, roughly $4,840 in tax savings. At a MAGI of $130,000, the allowance is cut by 50 cents per dollar over $100,000: a $30,000 excess reduces the allowance by $15,000 to $10,000, so only $10,000 of the loss is usable and $12,000 is suspended. At $155,000 MAGI the allowance is zero and the full $22,000 is suspended and carried forward. Two-earner households often cross the $150,000 line without realizing it, which is why the allowance frequently disappears exactly for the households most able to buy rentals.
The non-working-spouse REPS strategy
Because a full-time W-2 employee almost never clears the 750-hour and 'more than half your working time' tests, the real estate professional path is usually pursued through a spouse who does not work full-time elsewhere. On a joint return, only one spouse needs to qualify as the real estate professional. The catch is that spouses cannot combine hours to reach the 750-hour threshold — one spouse must hit it alone — but once that spouse qualifies, the couple's material participation in each rental (both spouses' hours count for material participation) can make the losses non-passive on the joint return. This is the classic 'my spouse manages the rentals full-time' structure. It only works with genuine, well-documented hours; the Tax Court regularly rejects REPS claims built on estimates.
The short-term rental strategy in detail
The short-term rental route is powerful precisely because it sidesteps the REPS hour tests. If your property's average guest stay is seven days or less, it is not a 'rental activity,' so you do not need 750 hours or real-estate-professional status — you only need to materially participate, most cleanly by exceeding 500 hours or by the '100 hours and more than anyone else' test. A W-2 employee who self-manages an Airbnb (handling bookings, guest communication, turnovers, and maintenance) can plausibly meet the 100-hours test if no cleaner or co-host participates more. Pair this with a cost segregation study and bonus depreciation, and a large first-year paper loss becomes deductible against your salary. The two most common ways this fails on audit are using a full-service property manager (who then participates more than you) and keeping no contemporaneous time log.
What happens to the losses you can't use
A loss you cannot deduct this year is not gone — it is suspended under Section 469 and carried forward indefinitely. Suspended losses become usable in three ways: they offset passive income in a future year (net income from this or another rental), they are freed as your MAGI drops back under the phase-out in a future year (restoring some allowance), or they are fully released when you sell the property in a taxable disposition, when the entire accumulated balance offsets the gain and any other income. Tracking the suspended amount on Form 8582 every year is essential — investors who lose the paperwork often forget to claim a large deduction they are entitled to at sale.
Documentation that protects the deduction
Every one of these paths turns on facts the IRS can and does examine. For the active-participation allowance, keep evidence you make management decisions — approved applications, signed leases, repair authorizations. For REPS or a short-term rental, the crucial record is a contemporaneous time log: date, hours, and a description of each activity, kept as you go rather than reconstructed later. Retain guest calendars, cleaning schedules, and vendor communications to corroborate the hours. Because the passive-loss exceptions are among the most litigated areas of individual tax, the difference between a deduction that holds up and one that is disallowed with penalties is usually the quality of the records, not the strength of the legal theory.
How these paths pair with depreciation
The reason investors fight so hard to make rental losses deductible is that the losses are frequently created by depreciation rather than by cash bleed. A property that is cash-flow positive can still show a tax loss once you subtract the annual depreciation deduction — and a cost segregation study with bonus depreciation can turn that into a very large first-year loss. If that loss is trapped as passive, the depreciation only shelters future passive income; if one of these three paths makes it non-passive, the same depreciation shelters your W-2 salary now. This is why the short-term-rental-plus-cost-seg combination and the non-working-spouse REPS structure are so heavily used: they convert a paper depreciation loss into a current, high-value deduction against ordinary income. The trade-off is future depreciation recapture at sale, so model the full arc, not just year one.
Don't overlook the state consequences
Federal deductibility is only part of the picture. Most states begin from your federal AGI or taxable income, so a rental loss you are allowed to deduct federally generally flows through to your state return as well — and one that is suspended federally is usually suspended for state purposes too. But states diverge on the edges: some do not conform to bonus depreciation and require an add-back, which can make your state taxable income higher than your federal even in a big cost-seg year, and states with no income tax raise no loss question at all. If you live in one state and own the rental in another, you may file a nonresident return where the property sits, and how each state treats the loss affects your total benefit. Confirm state conformity before assuming your federal loss produces an equal state saving.
Grouping multiple rentals to reach material participation
Investors who own several rentals and want the REPS path face a hidden hurdle: to make each rental's losses non-passive, you must materially participate in each one separately — a hard test to meet property by property. The regulations offer a fix. Under Reg. 1.469-9(g), a qualifying real estate professional can make a one-time election to treat all rental real estate interests as a single activity. With the election, your hours across the whole portfolio are aggregated, so meeting the 500-hour material participation test once covers every property, rather than needing 500 hours on each. The election is powerful but sticky — it binds future years and can complicate the release of suspended losses when you sell an individual property — so make it deliberately, with a clear statement attached to your return, and understand the trade-offs before electing.
Frequently asked questions
Can I deduct rental losses against my salary?
Generally no — rental losses are passive and cannot offset active (W-2) income. The exception is the $25,000 allowance for active participants with MAGI under $150,000, or REPS, or a short-term rental with material participation.
What happens to suspended rental losses?
They carry forward indefinitely. When you sell the property, all suspended passive losses are released and can offset the gain or any other income in the year of sale.
What is active participation in a rental?
Active participation requires making management decisions (approving tenants, deciding on major repairs, setting rent levels), but you can still use a property manager. It is a lower bar than material participation.
Can my spouse qualify as a real estate professional if I work full-time?
Yes. On a joint return only one spouse needs to meet the 750-hour and more-than-half-of-working-time tests. Spouses cannot pool hours to reach 750, but once one spouse qualifies, both spouses' hours count toward materially participating in the rentals.
Does the $25,000 allowance apply to short-term rentals?
No. The $25,000 special allowance is for rental real estate with active participation. A short-term rental with an average stay of seven days or less is treated as a business, not a rental activity — but if you materially participate, its losses are non-passive and fully deductible with no MAGI phase-out.
How many hours do I need for a short-term rental loss to be non-passive?
You must materially participate. The cleanest test is more than 500 hours in the activity, but the '100 hours and more than any other individual' test often applies to a self-managed short-term rental. Keep a contemporaneous log to substantiate the hours.
