Form 8582-CR and Form 8810: How Passive Activity Limits Apply When You Buy Tax Credits

When an individual, estate, trust, closely held C corporation or personal service corporation buys a transferable credit under §6418, the passive activity rules usually cap how much of that credit can be used this year. Individuals, estates and trusts figure that cap on Form 8582-CR. Closely held and personal service C corporations use Form 8810. This page is a high-level educational walkthrough of those forms for credit buyers—not a worksheet, not a filing service and not tax advice. Confirm every calculation with your CPA.

Form 8582 vs Form 8582-CR vs Form 8810

• Form 8582 figures the passive activity loss allowed for the year (Pub. 925; IRS About Form 8582). It is about losses, not credits.
• Form 8582-CR is used by noncorporate taxpayers to figure the current-year passive activity credit (including prior-year unallowed credits) and the amount allowed this year (IRS About Form 8582-CR; Instructions for Form 8582-CR, Rev. December 2025).
• Form 8810 is the corporate counterpart: personal service corporations and closely held corporations use it to figure passive activity losses and credits (IRS About Form 8810; Instructions for Form 8810).

A widely held C corporation is generally outside §469 and does not file Form 8810. See closely held C corporations and the passive activity rules and the C corporation §48E buyer guide.

Why a purchased §6418 credit shows up here

The final transfer regulations treat a purchased credit as determined in connection with a trade or business and subject to §469 for the buyer (Treas. Reg. §1.6418-2(f)(3)). Buying the credit does not give you an ownership interest in, or participation in, the seller's project, so for most individual buyers the credit is a passive activity credit.

IRS transferability FAQ Q15 states that individuals, estates and trusts, closely held C corporations and personal service corporations may purchase and claim transferable credits, but "will be subject to the passive activity rules for any purchased credits." Generally, that means they can use purchased credits only against tax attributable to passive income. The same FAQ notes that most taxpayers do not have much passive income tax liability, because it generally does not include tax from most investment (portfolio) activities. Wages and portfolio income cannot be offset; see why W-2 income cannot be offset and the full §469 guide for transferable credits.

§469(d)(2) defines the passive activity credit as the amount by which credits from passive activities exceed the regular tax liability allocated to passive activities. That excess is not lost; it carries forward (§469(b)).

Form 8582-CR in outline (individuals, estates and trusts)

This is a map of the computation, not a substitute for the worksheets in the instructions.

1. Start from net passive income. Generally you have net passive income if Form 8582, line 3, shows income (Instructions for Form 8582-CR, Part I / line 6 discussion). Net passive income is after current passive losses and suspended loss carryovers. If net passive income is zero or you have a net passive loss, there is generally no tax attributable to net passive income against which a purchased credit can be allowed this year (special rental-real-estate allowances, discussed below, usually do not help a purchased §48E credit).
2. Combine passive activity credits in Part I, including prior-year unallowed credits that belong to this computation. If those credits exceed the tax attributable to net passive income, you have a passive activity credit for the year.
3. Figure tax attributable to net passive income. The Form 8582-CR instructions describe this as a comparison of regular tax computed with and without net passive income—the difference is the ceiling for the credit. Your CPA runs this from the actual return, not from a rough tax-rate times income shortcut. See also how purchased credits offset tax on passive income.
4. Apply any special allowance only if it actually applies. Individuals and qualifying estates that actively participated in rental real estate activities may have a special allowance on certain credits (Instructions for Form 8582-CR, lines 1a–1c). That allowance is about credits from those rental activities. A credit you bought under §6418 is generally not a rental-real-estate credit of yours. Do not assume the $25,000 rental allowance increases room for a purchased §48E credit; ask your CPA.
5. Part V figures the passive activity credit allowed for the year. If you have only one type of credit, that allowed amount is what you take to the reporting form. If you have credits from more than one activity or more than one type of credit, the instructions direct you to worksheets that allocate allowed and unallowed amounts. Keep a record of each unallowed credit and the activity to which it belongs so it can be claimed in a later year (Instructions for Form 8582-CR, Part V).
6. Report the allowed amount on Form 3800. The December 2025 instructions say to enter the passive activity general business credits allowed on Form 3800, on the lines that apply (they caution that line numbers may change for tax years beginning after 2025). Then complete the transfer election statement and Form 3800 reporting for the §6418 purchase (registration number, column (f), attached statement).

Form 8810 for closely held and personal service C corporations

Personal service corporations and closely held corporations that have losses or credits (including carryforwards) from passive activities must file Form 8810 (Instructions for Form 8810). A corporation is closely held, for this purpose, if at any time during the last half of the tax year more than 50% in value of its outstanding stock is owned, directly or indirectly, by or for not more than five individuals, and it is not a personal service corporation.

• Personal service corporation: a passive activity credit exists if credits from passive activities (including prior-year unallowed credits) exceed the tax attributable to net passive income—the same style of ceiling that applies to individuals.
• Closely held C corporation (not a PSC): a passive activity credit exists if those credits exceed the sum of the tax attributable to net passive income and the tax attributable to net active income. That broader ceiling comes from §469(e)(2), which lets a closely held C corporation (other than a PSC) treat net active income as available for this purpose. Net active income is taxable income determined without certain items, including net passive income or loss and portfolio income (Instructions for Form 8810, line 2). In educational terms, a closely held operating company may be able to use a purchased credit against tax on its net active business income, not only against tax on passive income. How the numbers flow is a CPA computation; this page does not run Form 8810.

Allowed passive activity credits then flow to Form 3800, just as they do for individuals. See the closely held C corporation guide.

What this means when you size a §48E purchase

1. Document the income that is actually passive (or, for a closely held C corporation, net active income) with your CPA. See how to document passive income and the seven material participation tests.
2. Have your CPA compute the tax attributable to that income on Form 8582-CR or Form 8810, then apply §38(c).
3. Size the purchase to the allowed amount, with a margin if the projection is uncertain. Unused passive activity credit carries forward; it is a backup, not a plan to over-buy. See carryforward rules.
4. Complete the §6418 transfer mechanics (registration number, cash purchase from an unrelated seller, transfer election statement) and report on Form 3800. Start with the §48E buyer guide or the passive-income investor guide.
