Rental Real Estate Losses: Passive Limits, NOLs, and At-Risk Rules

Rental real estate loss deduction limits work in layers: a loss on your rental has to pass through the at-risk rules, the passive activity rules, the excess business loss cap, and then the net operating loss ceiling before it actually reduces your tax bill. Anything a layer blocks is suspended and carried forward under that layer’s own rules, so your usable deduction in a given year is often smaller than your economic loss on paper. The losses are not gone; they wait for future passive income, a qualifying disposition, or a year when your income profile changes.

The Four Filters, in Order

Sequence matters, because each filter uses the output of the one before it. Run them out of order and you overstate what you can deduct.

Basis. You cannot deduct more than your tax basis in the property or interest.
At-risk rules under Section 465. Your deductible loss is capped at what you could actually lose financially.
Passive activity rules under Section 469. Losses that survive at-risk are limited to offsetting passive income unless an exception applies.
Excess business loss limitation under Section 461(l). An annual aggregate cap on total business losses used against non-business income.

Anything disallowed at the last step converts into a net operating loss carryforward under Section 172, which has its own ceiling on how much of a future year’s taxable income it can wipe out. Each suspended amount carries forward under the rules of the step that stopped it, so tracking which bucket a loss sits in is part of the job.

At-Risk Rules

Section 465 caps your deductible loss at the amount you have genuinely at stake in the activity.¹ Your at-risk amount includes cash you invested, the adjusted basis of property you contributed, and amounts you borrowed for which you are personally liable.

Non-recourse debt generally does not count, because the lender’s only remedy is to seize the property. There is one important exception: qualified non-recourse financing from a bank, credit union, or government entity, secured by the real property itself, does count toward your at-risk amount.¹ Most conventional mortgages on rental real estate from institutional lenders qualify, so the at-risk rules rarely block losses for a typical leveraged purchase. Seller-financed deals and loans from related parties are where investors more often get caught.

Passive Activity Loss Limits

Losses that clear at-risk hit the passive activity wall. Section 469 classifies all rental real estate as passive by default, no matter how many hours you put in.² This is the rule that stops rental depreciation from sheltering wages, salaries, or portfolio income like dividends and capital gains.

Passive losses only offset passive income. Any excess is suspended and carries forward indefinitely, sitting on the books until you generate enough passive income to absorb it or dispose of the property in a fully taxable transaction. The tracking happens on Form 8582.³

The $25,000 Active Participation Allowance

If you actively participate in your rental, you can deduct up to $25,000 of rental losses against non-passive income like wages each year.⁴ Active participation is a lower bar than material participation: approving tenants, setting rent, and authorizing repairs count. You need to own at least 10% of the property.

The catch is income-based. The $25,000 allowance phases out by 50 cents on every dollar your modified adjusted gross income exceeds $100,000, and it disappears at $150,000.⁵ At $120,000 of modified AGI, you lose $10,000 of the allowance (half of the $20,000 overage), leaving $15,000 usable against non-passive income.

These figures are fixed in the statute and are not indexed for inflation. Married taxpayers filing separately face tighter limits: the allowance drops to $12,500 and the phase-out begins at $50,000. If you file separately and live with your spouse at any point during the year, the allowance is zero.⁴

Real Estate Professional Status

The most powerful exception to the passive rules is qualifying as a real estate professional under Section 469(c)(7). If you qualify, your rental real estate is no longer automatically passive, and losses can offset wages, business income, and other non-passive earnings with no dollar cap.²

Both tests must be met in the tax year:

More than half your working hours are in real property trades or businesses in which you materially participate. Development, construction, management, leasing, and brokerage all count, not just owning rentals.
More than 750 hours of service in those real property trades or businesses during the year.

On a joint return, only one spouse needs to meet both tests, but that spouse’s hours alone must clear the thresholds.² Work as an employee does not count unless you own at least 5% of the employer. This is where a lot of W-2 earners fail: a full-time salaried job almost always means more than half your working hours are outside real estate.

The Grouping Election

Qualifying as a real estate professional removes the automatic passive label, but you still have to materially participate in each rental for its losses to be non-passive.⁶ Proving that property by property is difficult with a portfolio, so the code lets you elect to treat all your rental real estate interests as a single activity. Combined hours across every property then count together.

You make the election by attaching a statement to your return for the first year it applies. The statement must identify the activities and declare that they form an appropriate economic unit.⁷ Without the disclosure, each property is treated separately. A late disclosure is still accepted if prior returns were filed consistently with the grouping and you attach the statement to the return for the year you discover the omission.

Material Participation

Whether you are a real estate professional testing a grouped activity or a short-term rental owner, the IRS recognizes seven ways to prove material participation. The two most commonly used are logging more than 500 hours in the activity, or participating for more than 100 hours when no one else participates more.⁶ Calendars, appointment books, or written summaries all work. Daily logs help but are not required.

Short-Term Rentals: The 7-Day Rule

Property rented with an average customer stay of seven days or fewer is not treated as a rental activity under the passive loss rules at all.⁶ The activity is classified as a trade or business, and losses are non-passive as long as you materially participate.

The practical result: an owner who materially participates in a short-term rental can deduct losses against wages and other active income without qualifying as a real estate professional and without being pinched by the $25,000 cap or its $100,000 phase-out. The average stay is total rental days divided by the number of rental periods during the year. If you sit near the seven-day line, a few extended bookings can push you over and reclassify the whole activity as a rental subject to the passive rules.

Excess Business Loss Cap

Losses that survive the passive filter face one more hurdle. Section 461(l) caps the total net business losses an individual can use to offset non-business income in a single year. All your business activities are aggregated first, so rental losses combine with income and losses from sole proprietorships, partnerships, and S corporations before the cap applies.

For tax year 2025, the cap is $313,000 for single filers and $626,000 for married couples filing jointly.⁸ For 2026, the thresholds become $256,000 for single filers and $512,000 for joint returns, reflecting adjustments under the One, Big, Beautiful Bill Act signed into law in 2025.⁹ The amounts adjust annually for inflation.

Any business loss over the cap is disallowed for the year and converts into a net operating loss carryforward.¹⁰ The calculation happens after at-risk and passive rules have done their work, so only losses that already cleared those filters count here. For most rental investors who aren’t also running other large businesses, this cap rarely bites. It shows up for real estate professionals with heavy depreciation across a portfolio, or investors also holding other pass-through businesses generating losses in the same year.

Net Operating Loss Carryforward and the 80% Ceiling

Disallowed excess business losses become net operating losses under Section 172 and carry forward indefinitely.¹¹ For losses arising in tax years beginning after December 31, 2017, carrybacks are no longer permitted except for farming losses.¹²

When you use a post-2017 NOL in a future year, the deduction is capped at 80% of your taxable income calculated without the NOL.¹¹ The remaining 20% is always subject to tax, no matter how large your carryforward. An NOL can never zero out your tax bill in a future year.

Older NOLs arising before 2018 that you’re still carrying follow different rules: no 80% limit, but a 20-year window rather than an indefinite one. If you hold both, the older losses are applied first.

Releasing Suspended Passive Losses

Suspended passive losses accumulate year after year, but they don’t disappear. What frees them depends on how the property leaves your hands.

Fully Taxable Sale

Sell your entire interest in a rental activity in a fully taxable transaction and all suspended passive losses from that activity release at once. They first offset any gain from the sale, and any remainder becomes non-passive, so it can reduce wages, investment income, or any other taxable income.¹³ The words that matter are “entire interest” and “fully taxable.” A partial sale or a Section 1031 like-kind exchange does not trigger the release. Sales to related parties delay the release until the related party sells to an unrelated buyer.

Death

When a rental owner dies, suspended losses are deductible on the decedent’s final return, but only to the extent they exceed the step-up in basis the heir receives.¹³ If a property has $80,000 in suspended losses and the heir’s stepped-up basis exceeds the decedent’s adjusted basis by $60,000, only $20,000 is deductible on the final return. The other $60,000 is absorbed by the basis step-up and disappears. When the step-up equals or exceeds the total suspended losses, no deduction is available.

Gifts

Gifting a rental releases suspended losses to no one. The suspended amount is added to the property’s basis immediately before the transfer.¹⁴ The higher basis reduces the recipient’s future gain, but neither party ever deducts the suspended losses. If the property’s fair market value at the time of the gift is below the donor’s adjusted basis, the suspended losses can effectively vanish, since the recipient’s basis for calculating a loss on a later sale is limited to fair market value at the time of the gift.

Keeping Track

Form 8582 is the primary form for calculating how much of your passive rental losses are currently deductible and how much is suspended.³ Allowed amounts flow to Schedule E and other schedules depending on the activity. NOL carryforwards from excess business losses are tracked separately on Form 172.

The IRS does not keep a running balance for you. Prior-year unallowed amounts live in your previous Form 8582 worksheets, and those figures feed the current year’s calculation. Losing track of either number means leaving deductions on the table, sometimes for years, and the moment those numbers matter most is often the year you sell.
