Updated October 7, 2026. Quick answer: Form 8582 limits losses from passive activities, which are business activities without material participation and rental activities. Losses that exceed passive income are generally suspended and carried forward. Rental real estate with active participation gets a special allowance of up to $25,000 that shrinks once modified adjusted gross income passes $100,000 and ends at $150,000. A taxable sale of the entire interest to an unrelated person releases the losses.

What Form 8582 does
“Form 8582 is used by noncorporate taxpayers to figure the amount of any passive activity loss (PAL) for the current tax year and to report the application of prior-year unallowed PALs.” The instructions define the trigger: “A PAL occurs when total losses (including prior-year unallowed losses) from all your passive activities exceed the total income from all your passive activities.”
Two kinds of activity are passive. They are “Trade or business activities in which you did not materially participate for the tax year.” and “Rental activities, regardless of your participation.” The consequence is stated plainly: “PALs can’t be used to offset income from nonpassive activities.” Rental income and its tax side are also covered on the Schedule E page.
Passive or nonpassive: what falls outside the form
Some activities are not passive at all. The list includes “Trade or business activities in which you materially participated for the tax year.” A rental real estate activity can also escape the label for a real estate professional, who must meet two tests: “More than half of the personal services you performed in trades or businesses during the tax year were performed in real property trades or businesses in which you materially participated, and” “You performed more than 750 hours of services during the tax year in real property trades or businesses in which you materially participated.”
On a joint return the test is not shared: “one spouse must separately meet both (2)(a) and (2)(b) without taking into account services performed by the other spouse.” The first of the seven material participation tests is “You participated in the activity for more than 500 hours.” A rental is passive even when the owner works at it: “A rental activity is a passive activity even if you materially participated in the activity”, except for a qualifying real estate professional.
The special allowance for rental real estate
“If you actively participated in a passive rental real estate activity, you may be able to deduct up to $25,000 of loss from the activity from your nonpassive income.” Active participation is a lower bar than material participation: “You may be treated as actively participating if, for example, you participated in making management decisions or arranged for others to provide services (such as repairs) in a significant and bona fide sense.” The ownership floor is “You aren’t considered to actively participate in a rental real estate activity if at any time during the tax year your interest (including your spouse’s interest) in the activity was less than 10% (by value) of all interests in the activity.”
Who can claim it, and how much, as the instructions print it for 2025:
| Filing situation | Maximum allowance | Modified AGI phase-out range |
|---|---|---|
| Single, or married filing jointly | $25,000 | $100,000 to $150,000 |
| Married filing separately, lived apart all year | $12,500 | $50,000 to $75,000 |
| Married filing separately, lived together at any time | None | Not eligible |
The rule for the middle range reads: “If your modified adjusted gross income is more than $100,000 ($50,000 if married filing separately) but less than $150,000 ($75,000 if married filing separately), your special allowance is limited to 50% of the difference between $150,000 ($75,000 if married filing separately) and your modified adjusted gross income.” At the top: “Generally, if your modified adjusted gross income is $150,000 or more ($75,000 or more if married filing separately), there is no special allowance.”
Worked example: Part II lines 4 to 9
Part II follows the form line by line. Line 4 is the smaller of the line 1d loss or the line 3 loss. Line 5 is $150,000 and line 6 is modified AGI. Line 7 subtracts line 6 from line 5. Line 8 is 50% of line 7 with a cap of $25,000. Line 9 is the smaller of line 4 or line 8. The instructions confirm the last step: “You enter $25,000 on line 9 (the smaller of line 4 or line 8, both treated as positive amounts).”
In this computed illustration, take a rental loss of $18,000 on line 4 and modified AGI of $120,000 on line 6. Line 7 is $150,000 minus $120,000 and equals $30,000. Line 8 is 50% of $30,000 and equals $15,000. Line 9 is the smaller of $18,000 and $15,000. So $15,000 of the loss is allowed against other income and $3,000 stays suspended. These figures are worked here from the form lines; the IRS does not print this example.
Modified AGI is not the same as AGI. “To figure modified adjusted gross income, combine all the amounts used to figure adjusted gross income, except don’t take into account:” passive losses, taxable social security, deductible traditional IRA contributions and the other items the line 6 list names. The instructions’ own example: “Your adjusted gross income on line 11 of Form 1040 or Form 1040-SR is $92,000 and you have taxable social security benefits of $5,500 on line 6b. Your modified adjusted gross income is $86,500” after subtracting the second figure from the first.
Parts I, III, and IV to IX in order
Complete Parts IV and V first. “Use Part IV for rental real estate activities with active participation.” “Use Part V for all other passive activities.” Their totals feed lines 1 and 2 of Part I, line 3 combines them, and if line 3 is zero or more all losses are allowed and the form stops there.
| Part | Job |
|---|---|
| IV | Rental real estate with active participation; columns (a) to (e) |
| V | Passive trade or business, other rentals, rental real estate without the allowance |
| II | Special allowance, lines 4 to 9 |
| III | Total losses allowed, line 11 |
| VI | Spreads the line 9 allowance across rental activities |
| VII | Allocates the unallowed (suspended) loss |
| VIII and IX | Allowed loss per activity, and the version for losses on two or more forms |
Column (c) in Parts IV and V picks up carryovers: “You find these amounts in Part VII, column (c), of your 2024 Form 8582.” In Part VIII, the unallowed column is the record to keep: “Keep a record of these amounts so the losses can be used to figure your PAL next year.”
Suspended losses and selling the whole interest
“PALs not allowed in the current year are carried forward until they’re allowed either against passive activity income; against the special allowance, if applicable; or when you sell or exchange your entire interest in the activity in a fully taxable transaction to an unrelated party.”
The disposition rule: “If you disposed of your entire interest in a passive activity or a former passive activity to an unrelated person in a fully taxable transaction during the tax year, your losses allocable to the activity for the year aren’t limited by the PAL rules.” When the combined result is a loss, “All losses (including prior-year unallowed losses) are allowed in full.” A partial sale does not release anything: “A disposition of less than substantially all of an entire interest doesn’t trigger the allowance of prior-year unallowed losses.”
The IRS example 2 uses a $3,330 current loss plus a $1,115 carryover against a $2,000 gain, which gives “($3,330 + $1,115 = $4,445)” of losses reported in full outside Form 8582. For rentals sold or inherited, see selling a rental with tenants and heirs inheriting a rental.

Common mistakes
- Treating a rental as nonpassive because the owner works at it. A rental is passive regardless of participation unless the owner is a qualifying real estate professional.
- Using plain AGI on line 6. Modified AGI adds back items such as taxable social security and deductible traditional IRA contributions, and the allowance phases out between $100,000 and $150,000 of that figure.
- Putting a prior-year loss in Part IV when active participation was missing in either year. The instructions send it to column (c) of Part V instead.
