Passive Activity Loss Carryforward Calculator (2026)

Years of depreciation deductions that your tax preparer has been "suspending" on Form 8582 — here's what those suspended losses are actually worth and when you can use them. Enter your carryforward balance, current-year rental income or loss, and participation status to see exactly how much is unlocked this year and what each exit strategy would be worth.

How passive activity loss carryforwards work

Why your losses are suspended in the first place

Under IRC §469(c)(2), rental real estate is passive per se — the law doesn't care how many hours you put in. A passive loss can only offset passive income; it can't reduce W-2 wages, business income, or any other active/portfolio income. Each year you generate a net rental loss that exceeds your passive income, the excess suspends as a carryforward on Form 8582.¹

For most landlords with W-2 income above $150,000, every dollar of depreciation and rental expense excess becomes a suspended loss — deferred indefinitely but not lost. The losses accumulate year after year until a triggering event forces recognition.

What unlocks suspended losses

The $25,000 allowance — useful only below $150K AGI

IRC §469(i) provides a safety valve: if you actively participate (approve tenants, set rents, authorize repairs — no hour minimum, just meaningful decision-making) and own at least 10% of the activity, you can deduct up to $25,000 of rental losses against ordinary income.³

The phase-out is what catches most investors:

The $100K–$150K threshold has not been inflation-adjusted since 1986 and applies to 2026 exactly as written. For most investors building meaningful real estate portfolios, the allowance is zero — their AGI alone exceeds $150K before counting any rental income.

1031 exchanges do NOT release suspended losses

This surprises many investors. A 1031 exchange is a continuation of the investment — the activity doesn't end, so §469(g) doesn't trigger. Suspended PALs from the relinquished property transfer to the replacement property and continue accumulating. The losses stay suspended until you either generate passive income, qualify for REPS, or eventually sell without a 1031.⁴

The practical implication: an investor who has done four consecutive 1031 exchanges over 20 years may have enormous suspended losses that haven't reduced a single dollar of tax. When they finally sell or convert to passive income, those losses can create a significant tax benefit all at once.

REPS unlocks the carryforward retroactively

When you qualify for Real Estate Professional Status under IRC §469(c)(7), your rental activities are reclassified as non-passive for that year. This means both current-year losses AND all prior suspended carryforwards are released as ordinary losses in the year you first qualify — not just going forward. A landlord with $200,000 in accumulated suspended losses who qualifies for REPS in year 10 can deduct all $200,000 against W-2 income in that year (subject to the at-risk rules under §465, which are rarely an issue for direct rental property owners).⁵

How suspended losses interact with the gain at sale

When you sell a property, two things happen simultaneously under §469(g): (1) all suspended PALs from that property are released, and (2) those losses offset the gain from the sale — before you owe any tax. This can dramatically reduce the exit tax bill. A property with $80,000 in suspended losses and a $180,000 gain nets to a $100,000 taxable gain. Without the PAL release, you'd owe tax on $180,000. The suspended losses aren't a consolation prize — they're a built-in tax offset at exit.

Note: the 1031 exchange forfeits this offset because the disposition isn't fully taxable. If the suspended losses are large relative to the expected gain, sometimes a sale makes more tax sense than a 1031 — especially if your replacement property options are limited.
