LIHTC Recapture: Triggers, Accelerated Portion, and Interest

LIHTC recapture is the IRS clawing back part of the Low-Income Housing Tax Credits you already claimed, plus interest, when a project falls out of compliance during its 15-year compliance period. The amount clawed back is one-third of the credits you claimed in prior years, known as the accelerated portion. Two events trigger it: disposing of the building or your interest in it, and a drop in the building’s qualified basis from one year-end to the next.¹

What Triggers Recapture

The first trigger is a disposition. Selling the building or transferring a partnership interest during the compliance period puts the credit at risk, even if the property is fully occupied by qualifying tenants and running smoothly.² There is one carve-out. Recapture does not apply if the building is reasonably expected to keep operating as a qualified low-income project for the rest of the compliance period.¹ In practice, that means a purchase agreement with a commitment from the buyer to maintain low-income status. Sell without that assurance and you absorb the full recapture plus interest.

The second trigger is a drop in qualified basis. If the qualified basis at the end of a taxable year is lower than it was at the end of the prior year, recapture applies to the difference.¹ Qualified basis falls when units originally set aside for low-income tenants get rented to people who don’t qualify, when vacant units go to higher-income households, or when the available unit rule is broken. Because the measurement date is the last day of the taxable year, a mid-year dip that recovers by December 31 doesn’t cause a hit.

How Much You Owe: The Accelerated Portion

Recapture does not claw back every credit dollar you’ve ever claimed. It targets what the statute calls the accelerated portion, which is one-third of the credits claimed through the date of the violation. The remaining two-thirds represent credits you earned through actual compliance, and those stay with you.

The math comes from the mismatch between the credit period and the compliance period. LIHTC credits are claimed over 10 years, but compliance is required for 15.³ Each year you claim 1/10 of the total credits. Spread evenly over 15 years, you would have claimed 1/15 per year. The difference — 1/10 minus 1/15 — equals 1/30 of total credits per year, or exactly one-third of each year’s actual claim.¹

Recapture applies only to credits tied to the qualified basis that was actually lost. If half the building’s qualified basis dropped out, you recapture one-third of the credits attributable to that half, not to the whole building. Start by pulling total credits claimed on Form 8586 in every prior year, isolate the portion tied to the lost basis, then take one-third of that figure.⁴

A Simplified Example

Say a project generated $100,000 in annual credits over 10 years, and a full recapture event hits at the start of year seven. You’ve claimed $600,000 through year six. The accelerated portion is one-third of that, or $200,000. Interest then accrues on the credit from each individual year, running from that year’s return due date. The final liability is $200,000 plus several years of compounded interest, which pushes the total well above the base amount.

Interest on the Recapture

Interest is not a small add-on. It accrues at the overpayment rate set under Section 6621, which for non-corporate taxpayers is the federal short-term rate plus three percentage points.⁵ For the first quarter of 2026 that rate is 7 percent per year, compounded daily; for the second quarter it dropped to 6 percent.⁶

Interest runs separately for each prior year’s credit, starting from the due date of that year’s return. A recapture event in year eight means you pay interest on year-one credits for seven years, year-two credits for six years, and so on down the line. Getting the year-by-year calculation wrong is a common audit issue, so most owners run the numbers through a tax professional rather than a spreadsheet.

When Recapture Does Not Apply

Some drops in qualified basis are excused. If the loss comes from a casualty such as fire or storm, recapture does not apply as long as the property is restored within a reasonable period.⁷ The statute does not fix a number of months, so the practical standard depends on the damage and local rebuilding timelines. Document restoration efforts carefully in case the IRS later asks whether the timeline was acceptable.

The IRS can also waive recapture on application by the taxpayer for a de minimis error in meeting set-aside requirements.¹ Waivers are not automatic. You have to ask, and you have to show the error was genuinely minor rather than a pattern of loose management. A mid-year dip that reverses by December 31 also avoids recapture, since qualified basis is measured on the last day of the taxable year.

Reporting on Form 8611

Recapture is reported on IRS Form 8611, “Recapture of Low-Income Housing Credit.”⁸ The form walks through the decrease in qualified basis, the accelerated portion of prior-year credits, and the interest. Individual filers carry the total to Schedule 2 of Form 1040; corporate filers use Schedule J of Form 1120. Attach the completed form to the return for the year the recapture event occurred.⁹

The recapture amount is added directly to your tax liability for that year, which can produce a large bill on a sizable project. Failing to file Form 8611 when a recapture event has occurred is effectively underreporting your tax, and the IRS can layer accuracy-related penalties on top of the recapture itself.

The Assessment Clock

If you dispose of a building and the qualified basis later drops, the IRS has three years from the date you notify them of the reduction to assess the recapture tax.¹ The clock starts when you report, not when the violation happens. Delaying notification does not protect you; it extends the window during which the IRS can come after the liability. Prompt filing on Form 8611 is the fastest way to start the limitations period and close out exposure.

Recapture Ends at Year 15, But Affordability Does Not

Recapture risk runs for 15 taxable years, starting with the first year of the credit period. After the 15th year, investors are no longer exposed to recapture.³

Affordability obligations are a different matter. Federal law requires a recorded extended use agreement that keeps the property affordable for at least 30 years from the start of the compliance period, meaning another 15 years past the recapture window.¹ Violating the extended use agreement does not trigger tax credit recapture, but it can cost future credits and draw enforcement from the state housing credit agency that allocated the credits. Recapture exposure ends at year 15. The affordability commitment does not.
