Form 8582 explained: who files it, how it works and where the carryover lives
The IRS form that limits passive losses, in plain words, with a worked example and what happens when you sell.
By Hans Goldstein, Enrolled Agent, admitted to practice before the IRS ·
What the form does
The 2025 instructions say it plainly: "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." PALs "can't be used to offset income from nonpassive activities," except through the special allowance.
Losses not allowed carry 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 parts, in plain words
| Part | What it does |
|---|---|
| Parts IV and V (completed first) | Part IV lists each rental real estate activity with active participation. Part V lists all other passive activities. For each activity, columns (a), (b) and (c) take current-year income, current-year loss and the prior-year unallowed loss. Their totals feed Part I |
| Part I, passive activity loss (lines 1 to 3) | Line 1 is rental real estate with active participation (1a income, 1b current-year loss, 1c prior-year unallowed loss, 1d combined). Line 2 is all other passive activities. Line 3 combines them. A loss on line 3 is the passive activity loss |
| Part II, special allowance (lines 4 to 9) | Applies the $25,000 rental real estate allowance. Line 5 is $150,000, line 6 is modified adjusted gross income, line 8 is 50% of the gap between $150,000 and your income (capped at $25,000), and line 9 is the smaller of line 4 or line 8 |
| Part III, total losses allowed (lines 10, 11) | Adds the passive income from Part I to the special allowance. Line 11 is the total passive loss allowed this year |
| Part VI | Spreads the special allowance among your rental real estate activities |
| Part VII, allocation of unallowed losses | Spreads the unallowed loss pro rata back to each activity. Column (c) is the carryover to next year, which you find in last year's Part VII |
| Part VIII, allowed losses | Shows the allowed loss for each activity and the form or schedule where it is reported (Schedule E, C, F or the K-1 line) |
| Part IX, losses on two or more forms | Used when an activity has losses on more than one form or schedule, including separating a 28% rate loss from other losses |
The worked example
Dana, a single filer with $120,000 of modified adjusted gross income, actively participates in a rental that loses $40,000 and has $10,000 of income from a passive limited partnership.
| Step | Amount |
|---|---|
| Rental loss (Part IV, feeds line 1b) | (40,000) |
| Other passive income (Part V, feeds line 2a) | 10,000 |
| Combined loss (line 3) | (30,000) |
| MAGI $120,000: $25,000 reduced by 50% of ($120,000 minus $100,000) | 15,000 special allowance |
| Allowed this year: passive income $10,000 plus allowance $15,000 | 25,000 |
| Suspended and carried forward | 15,000 |
Dana deducts $25,000 this year. The other $15,000 is a suspended loss allocated back to the rental in Part VII and carried to next year. The line references follow the 2025 form, so check the year's form.
When you sell
If you dispose of your entire interest to an unrelated person in a fully taxable transaction, the form tells you to combine all income and losses of the activity, including prior-year unallowed losses. If you have an overall loss, you do not use Form 8582 for the activity, and all losses are allowed in full.
If you have an overall gain, you enter the gain, the current-year loss and the prior-year unallowed loss in Part IV or V so the net gain can offset other passive losses, and all losses are allowed.
The exception: if you have an overall gain and the activity is a former passive activity, you report everything on the usual forms and do not use Form 8582. In both cases, report everything on the usual forms, mark them EDPA, and see what the allowed loss does to the rate.
The special-allowance exception to filing
You do not need Form 8582 if all of these are true: rental real estate with active participation is your only passive activity; no current-year or prior-year unallowed credits from a passive activity and no prior-year unallowed losses; total rental loss of $25,000 or less ($12,500 married filing separately and living apart); modified adjusted gross income of $100,000 or less ($50,000 married filing separately); and no interest as a limited partner or as a beneficiary of an estate or trust. Then you enter the loss straight on Schedule E.

Questions
What is Form 8582 used for?
Form 8582 is used by individuals, estates and trusts to figure the passive activity loss for the year and to report the use of prior-year unallowed losses. A passive activity loss occurs when total losses, including prior-year unallowed losses, from all passive activities exceed total income from all passive activities (2025 Form 8582 instructions).
Do I have to file Form 8582?
Generally yes if you have passive activity deductions, including prior-year unallowed losses. The exception: you actively participated in rental real estate, it was your only passive activity, you have no prior-year unallowed losses or credits, your total rental loss is not more than $25,000, your modified adjusted gross income is not more than $100,000 and you hold no limited partner or beneficiary rental interests (instructions, 'Who Must File').
Where do suspended losses show up on Form 8582?
You enter prior-year unallowed losses in column (c) of Part IV (rental real estate with active participation) or Part V (other passive activities), which feed Part I lines 1c and 2c. You find them in column (c) of Part VII of last year's Form 8582. Part VII then allocates this year's unallowed loss to each activity, and that figure carries to next year.
What is EDPA?
It stands for entire disposition of passive activity. When you dispose of your entire interest, you enter EDPA next to the entries on the forms and schedules where the gains and losses are reported (instructions).
Does Form 8582 apply to corporations?
No. Corporations subject to the passive activity rules use Form 8810. Passive credits are limited on Form 8582-CR.
Where does a released loss show up?
On the forms you normally use. With an overall loss from the disposition, none of it goes on Form 8582. With an overall gain, the gain and losses are entered in Part IV or V (columns (a), (b) and (c)), and the instructions say all of them are reported on the usual forms and schedules as well, so the net gain can offset losses from other passive activities.
