Passive activity loss rules: why your rental loss may be stuck in tax purgatory

By Tom, CPA · Updated October 25, 2026

TL;DR: Rental losses are generally passive and can only offset passive income. If you actively participate, up to $25,000 of rental losses can offset other income, phased out as MAGI goes from $100,000 to $150,000. Real estate professionals can escape passive treatment. Unused losses aren't lost; they carry forward and are released when you sell the whole property in a taxable sale.

Educational only, not tax, legal, or investment advice. Examples are illustrations, not predictions. Rules and limits change; verify current figures and talk to a qualified professional about your situation.

A newly minted landlord sees a $9,000 loss on the first rental, thanks mostly to depreciation, and does a little dance: a deduction! Then the tax software spits out Form 8582 and says, in effect, "Not so fast." Welcome to the passive activity loss rules, the tax code's way of saying a paper loss from rentals can't automatically shelter your salary.

These rules come from 1986, when tax shelters were sold the way gym memberships are sold in January. For FIRE households with rentals, they decide whether depreciation lowers your tax this year or waits in line. This guide uses IRS Publication 925 and Topic 425, current as of Oct 2026.

CPA Warning Label: A suspended loss is not a deduction you get this year. Count on it for cash flow planning and you may be surprised in April.

Passive by default

A passive activity is either a trade or business in which you don't materially participate, or a rental activity, which is generally passive no matter how many hours you put in. The main exception is for qualifying real estate professionals, covered below.

The core rule: passive losses can offset only passive income. They can't offset wages, interest, dividends, or capital gains on stocks. Portfolio income like dividends isn't passive income, even if you lounge in a hammock while earning it.

Some activities that look like rentals aren't "rental activities" under the rules. Examples include stays averaging 7 days or less, or 30 days or less with significant personal services. That's the basis of the short-term rental strategy.

Order of operations matters. Losses must first clear basis and the at-risk rules (Form 6198), then the passive rules (Form 8582), and afterward the excess business loss limitation applies to what's left.

Three participation standards people mix up

Using the wrong standard is the most common way a perfectly reasonable person ends up confidently wrong. "I'm very active with my rental" might get you the $25,000 allowance, but it won't make you a real estate professional.

$25k allowance and phase-out

Ordinary landlords get one important break. If you actively participate in a rental real estate activity, you can deduct up to $25,000 of rental losses per year against non-passive income.

• Active participation is a lower bar than material participation. Making management decisions, such as approving tenants, setting rents and approving expenses, generally counts, even if you use a property manager.
• You must own at least 10% of the property.
• The allowance phases out by 50% of modified AGI over $100,000, so it's gone at $150,000.
• Married filing separately and lived apart all year: $12,500, with the phase-out from $50,000 to $75,000. Married filing separately and lived together at any time: generally no allowance.

These dollar thresholds aren't indexed for inflation. They've been the same for decades, so more households phase out every year.

FIRE twist: early retirement can lower your MAGI dramatically. A couple who earned $300,000 while working, with suspended rental losses piling up, may find that in a low-income retirement year the $25,000 allowance suddenly becomes available. Losses that were stuck can start helping again, which pairs nicely with filling low brackets.

REPS requirements

Real estate professional status (REPS) removes the automatic passive label from your rentals. To qualify for a tax year, you must meet both:

1. More than half of the personal services you perform in all trades or businesses during the year are in real property trades or businesses in which you materially participate, and
2. You perform more than 750 hours of services in those real property trades or businesses.

Then you must also materially participate in the rental activity itself. Many owners with several properties elect to treat all rental interests as a single activity so the hours can be combined.

Key details:

• On a joint return, one spouse must meet both REPS tests alone. Spousal hours can't be combined for REPS, though a spouse's work does count for material participation.
• Hours as an employee in real estate generally count only if you're at least a 5% owner of the employer.
• Someone with a full-time non-real-estate job will almost never meet the "more than half" test. A full-time job is about 2,000 hours, so you'd need more than 2,000 real estate hours as well.

REPS is often used by households where one spouse doesn't work outside real estate. In FIRE, it can also fit the person who "retires" into managing a portfolio of rentals full time, which is arguably just a new job with worse hours.

Suspended losses

Losses you can't use don't disappear. They're suspended and carried forward indefinitely, tracked by activity. Each year they can offset:

• Passive income from the same activity or any other passive activity, including future rental profits once mortgages are paid down and depreciation runs out.
• Non-passive income, up to the $25,000 allowance if you qualify that year.

The big release comes when you dispose of your entire interest in the activity in a fully taxable transaction to an unrelated party. Then all suspended losses from that activity become deductible, first against income or gain from the activity, then against other income. Swapping through a 1031 exchange isn't a fully taxable disposition, so suspended losses generally stay suspended and carry over. Gifting a property also doesn't release them in the same way.

Keep every year's Form 8582 and worksheets. Suspended loss carryforwards are only as good as your records, and switching tax software has erased more carryforwards than any IRS agent.

Common mistakes with suspended losses include not carrying them into the new software or preparer's file, assuming a refinance or a partial sale releases them (it doesn't), and forgetting that state returns may track their own versions.

Example

Illustration: A married couple filing jointly has $135,000 of MAGI from wages and owns one long-term rental they actively manage. The rental shows a $14,000 tax loss: $24,000 rent minus $26,000 of expenses and interest, minus $12,000 of depreciation.

• Allowance phase-out: ($135,000 - $100,000) × 50% = $17,500 reduction
• Available allowance: $25,000 - $17,500 = $7,500
• Deductible this year: $7,500
• Suspended and carried forward: $6,500

Three years later, one spouse retires early and MAGI drops to $70,000. The full $25,000 allowance is now available, so that year's rental loss plus the $6,500 of old suspended losses (and any added since) can be used, up to $25,000. Or, if they sell the rental to an unrelated buyer in a taxable sale, all remaining suspended losses are released in the year of the sale.
