Form 8582: Passive Activity Loss Limitations
Published November 8, 2026
Form 8582 figures how much of a passive activity loss you can deduct this year. Individuals, estates, and trusts use it. Corporations use a different form. See Form 8810: Corporate Passive Activity Loss and Credit Limitations.
This post is general information from the 2025 Form 8582 and its instructions. It does not say how the rules apply to your activities.
What is a passive activity
The instructions say passive activities include two kinds of activities. The first is a trade or business where you did not materially participate during the year. The second is a rental activity. Rentals are passive no matter how much you took part.
Some activities are not passive. A trade or business where you materially participated is one example. A rental real estate activity where you materially participated, under the tests in the instructions, is another.
Why a passive loss may not reduce your income
Passive losses cannot offset nonpassive income. Wages and most investment income are nonpassive. A passive loss that is not allowed this year carries forward to later years.
Other limits come first. The instructions say basis and at-risk limits apply before the passive rules. The passive rules apply only to losses that pass those limits first.
A loss that is not allowed this year is not lost. It can reduce income in a later year, when the same activity has an overall gain. Your prior-year Form 8582 shows the carryover amounts. Keep it with your records.
Prior-year losses and gains
If an activity has an overall gain this year, its prior-year unallowed losses can offset that gain. This applies to the same activity. Only the losses from that activity are used.
Who must file
Form 8582 is generally filed when you have an overall gain from passive activities. It is also filed when you have prior-year unallowed losses. The instructions list an exception. In general, it covers the case where your only passive activities are rental real estate. You must have actively participated in them. Your loss from those activities must not be more than $25,000, or $12,500 if married filing separately. The instructions list other conditions, so read them before you skip the form.
The special allowance for rentals
If you actively participated in a rental real estate activity, you may deduct up to $25,000 of the loss. You can deduct it against nonpassive income. For married filing separately, the limit is $12,500. Active participation is a less strict test than material participation. It includes management decisions, such as deciding on rental terms.
The allowance phases out as income rises. The instructions say the allowance is reduced by 50% of the amount your modified adjusted gross income is over $100,000. For married filing separately, the threshold is $50,000. If modified adjusted gross income is $150,000 or more, the allowance is zero. For married filing separately, that point is $75,000.
A worked illustration
This is an arithmetic example, not an IRS example. Say your rental loss is $20,000. Your modified adjusted gross income is $120,000. The allowance is $25,000, less 50% of the $20,000 over $100,000. That leaves $15,000. You can deduct $15,000 this year. The other $5,000 is unallowed and carries forward, as the instructions describe.
Where the result goes
The amounts figured on Form 8582 are reported on Schedule E (Form 1040). Read the instructions for the line that fits your activity.
In short
Form 8582 limits losses from passive activities. Losses that are not allowed carry forward. The rental allowance is the main exception to know about.
