Form 8582: passive activity loss limitations
Form 8582 is the IRS form individuals, estates and trusts use to figure how much passive activity loss they can deduct this year. Passive losses offset passive income, plus up to $25,000 of rental real estate loss with active participation, and the rest carries forward.
“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.” IRS, Instructions for Form 8582 (2025)
Who has to file Form 8582?
Form 8582 is filed by individuals, estates and trusts that have passive activity deductions, including prior-year unallowed losses, according to the Instructions for Form 8582 (2025). A passive activity loss (PAL) exists when total losses from all passive activities exceed total passive income. Passive activities are trade or business activities without material participation and rental activities regardless of participation, unless the taxpayer is a real estate professional who materially participated. Corporations use Form 8810 instead.
A taxpayer can skip Form 8582 only if every one of these conditions holds for the year:
- Rental real estate with active participation was the only passive activity
- No prior-year unallowed losses and no current or prior-year passive credits
- Total rental real estate loss of $25,000 or less ($12,500 if married filing separately)
- Modified adjusted gross income of $100,000 or less ($50,000 if married filing separately)
- If married filing separately, lived apart from the spouse all year
- No interest held as a limited partner or as a beneficiary of an estate or trust
The 2025 form moved the old worksheets onto the form itself as Parts IV through IX, so the allocation of allowed and unallowed losses is now part of the filed return.
Where does each passive amount go on Form 8582?
Each passive amount on Form 8582 starts on another form or schedule and enters through Part IV or Part V, never directly on lines 1 or 2. Part IV is for rental real estate with active participation, and Part V is for every other passive activity, per the Instructions for Form 8582 (2025).
| Source | What it is | Form 8582 entry | Part I line |
|---|---|---|---|
| Schedule E, Part I, line 21 | Net income or loss of a rental property the taxpayer actively manages | Part IV, column (a) or (b) | 1a or 1b |
| K-1 (1065 or 1120-S), box 2 | Rental real estate, active participation, not a limited partner | Part IV, column (a) or (b) | 1a or 1b |
| K-1 (1065), box 2, limited partner | Rental real estate without active participation | Part V, column (a) or (b) | 2a or 2b |
| K-1, box 1, no material participation | Passive trade or business income or loss | Part V, column (a) or (b) | 2a or 2b |
| K-1, box 3 | Other rental income or loss | Part V, column (a) or (b) | 2a or 2b |
| Form 4797 gain or loss from a passive activity | Disposition of assets used in the activity | Same activity row, column (a) or (b) | 1a to 2b |
| 2024 Form 8582, Part VII, column (c) | Prior-year unallowed loss by activity | Part IV or V, column (c) | 1c or 2c |
| Form 6198, line 21 | Loss allowed under the at-risk rules | Part IV or V, column (b) | 1b or 2b |
| Form 1040, line 11, adjusted per instructions | Modified adjusted gross income | Part II | 6 |
A prior-year loss goes in Part IV, column (c), only if the taxpayer actively participated both in the year the loss arose and in the current year. Otherwise it goes in Part V. The allowed loss from Part VIII or IX then lands on Schedule E, line 22, for Part I rentals, or in column (g) of line 28 for a K-1, as covered on the Schedule E instructions page.
In what order do basis, at-risk and passive limits apply?
The passive loss limit on Form 8582 is the third of four loss limits, and the order is fixed. The Partner's Instructions for Schedule K-1 (Form 1065) (2025) list them in sequence: the basis limitation, the at-risk limitation, the passive activity limitation, then the excess business loss limitation.
- Basis: partner basis, or S corporation stock and debt basis on Form 7203
- At-risk: Form 6198 limits the loss to the amount at risk
- Passive: Form 8582 limits what survives to passive income plus any special allowance
- Excess business loss: Form 461 applies after the passive limit
Only the loss that passes the earlier tests enters Form 8582. The Instructions for Form 8582 say passive losses are subject to basis and at-risk limits first, and once a loss is allowable under those rules, the passive rules decide whether it is limited. A loss suspended at the at-risk step never reaches Form 8582 that year; it stays on Form 6198 and carries forward there. In practice, Form 6198 line 21 becomes the column (b) loss on Form 8582, and the two carryforwards are tracked separately because they free up under different conditions.
How does the $25,000 special allowance phase out?
The $25,000 special allowance on Form 8582 lets an individual who actively participated in rental real estate deduct up to $25,000 of rental loss against nonpassive income. The Instructions for Form 8582 (2025) set the maximum at $25,000 for single and joint filers and $12,500 for married individuals filing separately who lived apart all year. A married person filing separately who lived with the spouse at any time gets no allowance.
| Modified AGI (2025) | Special allowance | Married filing separately, lived apart |
|---|---|---|
| $100,000 or less | Up to $25,000 | Up to $12,500 if MAGI is $50,000 or less |
| Over $100,000 and under $150,000 | 50% of ($150,000 minus MAGI) | 50% of ($75,000 minus MAGI) |
| $150,000 or more | None | None at $75,000 or more |
Active participation is a lower bar than material participation. Approving tenants, setting rental terms and approving repairs count, but an interest below 10% by value or a limited partner interest does not qualify. Modified AGI on line 6 ignores items listed in the line 6 instructions, including the passive loss itself, taxable social security, deductible IRA contributions and the deduction for half of self-employment tax. IRC section 469(i)(3) sets the 50% phase-out above $100,000.
What does a Form 8582 calculation look like?
For example, a married couple filing jointly has $120,000 of modified AGI in 2025. They actively manage a duplex that shows a $30,000 loss on Schedule E, line 21, after the at-risk test (the bank mortgage is recourse). They also hold a partnership interest with $4,000 of passive income in K-1 box 1. Neither activity has prior-year unallowed losses, and they have no passive credits.
| Step | Form 8582 line | Amount |
|---|---|---|
| Duplex loss (Part IV, column (b)) | 1b and 1d | ($30,000) |
| Partnership income (Part V, column (a)) | 2a and 2d | $4,000 |
| Combine lines 1d and 2d | 3 | ($26,000) |
| Smaller of loss on line 1d or line 3 | 4 | $26,000 |
| Enter $150,000 | 5 | $150,000 |
| Modified AGI | 6 | $120,000 |
| Line 5 minus line 6 | 7 | $30,000 |
| 50% of line 7, capped at $25,000 | 8 | $15,000 |
| Special allowance, smaller of line 4 or 8 | 9 | $15,000 |
| Passive income | 10 | $4,000 |
| Total losses allowed | 11 | $19,000 |
| Unallowed duplex loss carried to 2026 | Part VII, column (c) | $11,000 |
The couple deducts $19,000 of the $30,000 duplex loss on Schedule E, line 22, and carries $11,000 forward. Part VI gives the full $15,000 allowance to the duplex, and Part VII allocates the $11,000 remainder, which is line 3 minus line 9. With MAGI of $150,000 or more, line 9 would be zero and only $4,000 would be allowed.
What do reviewers check on Form 8582?
A reviewer checking Form 8582 confirms six items, each tied to the 2025 instructions. The prior-year Form 8582 is the first document to pull, because Part VII, column (c), of that form is the only source for this year's column (c) carryforwards.
When a taxpayer disposes of an entire interest in a passive activity in a fully taxable sale to an unrelated party, prior-year unallowed losses from that activity are freed. The sale itself usually runs through Form 4797, so check that the carryforward was released in the same year. Real estate professional status also changes the form: rental real estate with material participation leaves Form 8582, and its prior-year losses become losses from a former passive activity under the instructions.
Every line checked against the documents the client sent
Filed reads the client's K-1s, rental records, prior-year Form 8582 and Form 6198, then checks every line of Form 8582 against them. Anything that doesn't tie comes back as a review item with a citation to the source.
Book a demoPart IV, column (c), shows $0 for the Oak Street rental, but the 2024 Form 8582, Part VII, column (c), shows $6,850 unallowed for that activity. Confirm whether the loss was released by a disposition or was dropped when the return rolled forward.
Common questions
What happens to passive losses that Form 8582 disallows?
Passive losses that Form 8582 disallows carry forward with no time limit, according to the Instructions for Form 8582. They are allowed in a later year against passive income, against the special allowance if it applies, or when the taxpayer sells the entire interest in the activity to an unrelated party in a fully taxable transaction.
Does the $100,000 to $150,000 phase-out range change each year?
The phase-out range for the $25,000 special allowance comes from IRC section 469(i)(3), which reduces the allowance by 50% of modified AGI above $100,000. The 2025 Instructions for Form 8582 use $100,000 and $150,000, or $50,000 and $75,000 for married individuals filing separately who lived apart all year.
Does a real estate professional file Form 8582?
A real estate professional files Form 8582 only for activities that remain passive. Rental real estate in which a qualifying real estate professional materially participated is not passive. The instructions require more than half of personal services and more than 750 hours in real property trades or businesses with material participation, met by one spouse alone on a joint return.
