The first 8611 I reviewed arrived as a quick estimate the partner needed before lunch. The building had been disposed of in November, the seller assumed the deal was clean because of a continued-operation covenant, and the workpaper blended prior credits from two owners on Line 1. Once we unwound the prior-owner credits, set Line 6 to 1.000, and applied the right Line 4 decimal, the recapture exposure tripled after per-year interest was layered in.
Form 8611 recaptures the Low-Income Housing Credit when qualified basis drops during the 15-year compliance period or a building is disposed of without meeting an exception. The Line 4 recapture percentage is year-specific, running from 0.333 in Years 2 through 11 down to 0.067 in Year 15, and Line 11 interest compounds daily at the IRC 6621 overpayment rate. The math is mechanical once the inputs across Forms 8586, 8609, and 8609-A reconcile by BIN, year, and qualified basis.
Key Takeaways
- You file one Form 8611 per building when qualified basis drops during the 15‑year compliance period or when you dispose of the building or an interest in it and do not meet an exception. Always match the BIN, address, and placed‑in‑service date to Form 8609.
- The Line 4 recapture percentage is year specific, Years 2–11, 0.333, Year 12, 0.267, Year 13, 0.200, Year 14, 0.133, Year 15, 0.067.
- For a sale or a minimum set‑aside failure, use 1.000 on Line 6 because the percentage decrease in qualified basis is treated as full. Exceptions can apply if continued compliance is reasonably expected and documented.
- Interest is computed at the IRS overpayment rate under IRC 6621, compounded daily under IRC 6622 and its regulations, through the earlier of the recapture‑year due date or the payment date. Keep a year‑by‑year worksheet.
- Section 42(j)(5) partnerships compute recapture at the entity level and report allocations to partners on Schedule K‑1. Partners do not file Form 8611 for that building.
What Form 8611 does and when it applies
Form 8611 is the IRS form you use to compute and report LIHTC recapture when a building’s qualified basis decreases during the 15‑year compliance period, or when you dispose of a building or an interest in it and you do not meet the procedures that would have avoided recapture. The form anchors to one building at a time, so you will prepare a separate 8611 for each affected property and you must use the exact BIN, address, and placed‑in‑service date shown on Form 8609.
Common triggers include nonqualified or vacant units that break rent restrictions, units not suitable for occupancy, a minimum set‑aside failure, unrepaired casualty outside a reasonable period, and dispositions. Disposing of a building generally triggers recapture unless it is reasonably expected that the building will continue to operate as a qualified low‑income building for the rest of the compliance period. Keep documentation for the expectation test and any covenants that support it.
Under IRC 42(j), the recapture amount equals two parts, the “accelerated portion” of credit from prior years that would not have been allowed if the 10‑year credit were spread ratably over 15 years, plus interest at the IRS overpayment rate, computed for each affected prior year. This statutory structure is why Line 4 uses a table of percentages and Line 11 requires a separate interest computation.
Pro tip, match your building data to Form 8609 and Form 8609‑A first. A wrong BIN or placed‑in‑service date can break the trail between 8611, 8586, and 8609‑A and slow the review.
The “year of recapture” percentage you will use
The form’s table gives you the Line 4 decimal. Use 0.333 for years 2–11, then it declines in years 12–15. This represents the accelerated share of the credit that is still “at risk” in that year. You will multiply that accelerated portion by the percentage decrease in qualified basis on Line 6 to arrive at the amount to recapture before offsets and interest.
Why dispositions often show 1.000 on Line 6
Line 6 is the percentage decrease in qualified basis. For a complete disposition, the decrease is generally treated as full, so 1.000, unless a documented expectation of continued compliance applies. For minimum set‑aside failures, the decrease is also treated as full. The Line 4 year percentage still applies, so do not replace the table with 100, set 1.000 only on Line 6 when appropriate.
Who this guide is for
You will get the most value if you are a tax partner, controller, or senior manager responsible for LIHTC compliance and reviews. If your firm has production crunches, rotating teams, or workpaper inconsistencies, use the checklists and examples below to standardize how your team prepares and reviews 8611 packages. And if your team is buried, you will find a short section at the end on where an offshore delivery partner can take on the prep work while you keep review control.
A quick “map” of the filing process
- Confirm the trigger and the recapture year, check for exceptions.
- Pull the building’s 8609, all 8609‑A schedules, and the 8586 history for that BIN.
- Reconcile total credits claimed, identify credits tied to post–first‑year additions, and compute the accelerated portion using the Line 4 table.
- Measure the percentage decrease in qualified basis, dispositions typically use 1.000.
- Apply offsets, then compute interest per year at IRC 6621 with daily compounding.
- For §42(j)(5) partnerships, complete Lines 1 through 7 at the entity level, skip Lines 8 through 15, and complete Lines 16 and 17 for entity‑level reporting and K‑1 allocations.
Gather everything that ties directly to the form and label it clearly. This keeps review time down and reduces back‑and‑forth with partners.
- Form 8609 to verify BIN, address, and placed‑in‑service date that must match Items C, D, and E on Form 8611.
- All Forms 8609‑A for the compliance period and any predecessor schedules to document qualified basis year by year.
- A complete Form 8586 history, by building, to support Line 1 and to isolate credits tied to post–first‑year additions for Line 2.
- Documentation for the specific trigger, for example a sale agreement, minimum set‑aside test, or casualty restoration proof.
- Worksheets for the annual interest calculation under IRC 6621 with daily compounding under IRC 6622 and 26 CFR 301.6622‑1.
Keep a single PDF workpaper per building with tabbed sections, 8609, 8609‑A by year, 8586 history, Line 4 table, Line 6 percentage support, and Line 11 interest worksheet. Future you will thank you at review time.
Step by step, how to complete Form 8611
Follow the lines in order. The form is short, but the math depends on clean inputs.
- Items A–F. Enter taxpayer name and TIN, the building’s street address, BIN, and placed‑in‑service date, all exactly as shown on Form 8609. If financed with tax‑exempt bonds, complete Item F as instructed.
- Line 1. Enter total LIHTC reported on Form 8586 in prior years for this building, before any reduction due to the tax liability limit. Do not include credits claimed by a prior owner.
- Line 2. Enter credits included on Line 1 that are attributable to additions to qualified basis after the first year, completing a separate Line 2 Worksheet for each prior year in which line 7 of Form 8609‑A (or predecessor Schedule A) was completed.
- Line 3. Subtract Line 2 from Line 1. This is the portion subject to recapture.
- Line 4. Enter the recapture percentage for the recapture year, Years 2–11, 0.333, Year 12, 0.267, Year 13, 0.200, Year 14, 0.133, Year 15, 0.067. Carry to at least three decimals.
- Line 5. Multiply Line 3 by Line 4 to get the accelerated portion of credit.
- Line 6. Enter the percentage decrease in qualified basis as a decimal carried to at least three places. For a complete disposition or a full minimum set‑aside failure, enter 1.000 unless an exception applies (and note, if the 40‑60 test was elected for this building you cannot switch to the 20‑50 test or the average income test to cure a failure, falling below 40% requires full recapture of the Line 5 amount).
- Line 7. Multiply Line 5 by Line 6. This is the accelerated portion recaptured (if accelerated credits were previously recaptured on this building in an earlier year, exclude that amount so it is not recaptured a second time). For flow‑throughs other than §42(j)(5) partnerships, the recipient skips Lines 1 through 7 and enters the passed‑through recapture directly on Line 8. Section 42(j)(5) partnerships go to Line 16 later.
- Line 8. If recapture is passed through from a flow‑through entity, enter that amount here.
- Line 9. Enter the unused portion of the accelerated amount from Line 7 as instructed. This is where prior unused credits can reduce the current recapture.
- Line 10. Subtract Line 9 from Line 7 or Line 8. If less than zero, enter 0.
- Line 11. Compute interest on the Line 10 recapture amount. Use the IRS overpayment rate under IRC 6621 for each affected prior year and compound daily under IRC 6622. Interest runs from the original due date for each prior year’s return to the earlier of the recapture‑year due date or the filing and full payment date. Include your year‑by‑year support.
- Lines 12–15. Add Line 10 and Line 11 for the total amount subject to recapture, reduce by any remaining unused credits, then compute recapture tax and any carryforward left.
- Lines 16–17, Section 42(j)(5) partnerships only. Compute entity‑level interest on Line 7, then total recapture on Line 17. Allocate to partners on Schedule K‑1.
A quick numerical example
Assume prior credits for Building A total 300,000 on Line 1. Additions to qualified basis after year one generated 30,000 of those credits, so Line 2 is 30,000 and Line 3 is 270,000. The recapture year is year 12, so Line 4 is 0.267. The accelerated portion on Line 5 is 72,090. You sold the building and did not meet an exception, so Line 6 is 1.000. Line 7 is 72,090. You have 10,000 of unused credits that tie to the accelerated portion, so Line 9 is 10,000, Line 10 is 62,090. You then compute Line 11 interest by year at the IRC 6621 overpayment rates with daily compounding, from each original due date through the earlier of the year‑of‑recapture due date or payment.
Always save the annual interest table you used. If an examiner asks how you got Line 11, you can produce the quarter‑by‑quarter rates and the daily compounding method on the spot.
The math behind recapture and interest, explained simply
The LIHTC is allowed over ten years, but the law treats the full benefit as if it were spread evenly over fifteen. The difference, one third in years 1–10, is the accelerated portion that can be recaptured if qualified basis drops during the 15‑year compliance period. That is why Line 4 uses a fixed table in years 2–11, then steps down in years 12–15 as the accelerated benefit “burns off.”
The Line 4 table you will reference
| Recapture year | Line 4 decimal |
| Years 2–11 | 0.333 |
| Year 12 | 0.267 |
| Year 13 | 0.200 |
| Year 14 | 0.133 |
| Year 15 | 0.067 |
| Use this table exactly as printed in the IRS form instructions. |
How to think about Line 6
Line 6 measures the percentage decrease in qualified basis. A complete sale usually means a full decrease, so 1.000, unless you satisfy the continued compliance expectation. If the drop is partial, compute the decimal decrease, then apply it to the accelerated portion from Line 5. Track any post–first‑year additions, since those can offset a decrease and avoid recapture for the net change.
Interest, the part many teams underestimate
Interest is not optional and it is not simple annual interest. The IRS compounds interest daily under IRC 6622, using the overpayment rate set quarterly under IRC 6621. For each prior year affected, start on that year’s original due date, run to the earlier of the current return’s due date or the filing and payment date, and document the math. Publishing notices list the quarterly rates, and the Internal Revenue Manual explains daily compounding.
Quick check, if your Line 11 is one line with a single percentage, it is probably wrong. Build a per‑year schedule with the applicable quarterly rates.
Special rules for partnerships and dispositions
If your partnership qualifies under Section 42(j)(5), meaning it has at least 35 partners (a married couple and their estates count as one partner for this test) and has not previously elected out, you compute recapture at the partnership level, not at the partner level. The partnership completes Form 8611, then allocates the amounts on Schedule K‑1. Partners generally do not file Form 8611 for that building, they report what flows through on the K‑1. This centralizes control and helps keep partner returns clean.
On a building sale, recapture generally applies unless you can document a reasonable expectation of continued compliance for the balance of the 15‑year period. This is where extended use agreements, binding covenants, and buyer representations matter. Keep that evidence with your workpapers.
Disposition and casualty exceptions you should know
- Qualified transfer with documented, reasonable expectation of continued compliance, no recapture.
- Section 42(j)(5) partnership interest transfer, recapture shifts to the partnership’s entity‑level computation.
- Casualty loss restored or replaced within a reasonable period, no recapture.
- Decreases in qualified basis fully offset by post–first‑year additions that generated allowable credits, no net recapture.
Workflow setup that shortens review time
- Keep a building‑level binder with 8609, all 8609‑A schedules, 8586 history, and prior 8611s.
- Standardize file names and version control so reviewers can trace Line 1 and Line 2 in minutes.
- Build an interest template that pulls IRC 6621 rates by quarter and applies daily compounding automatically.
- For §42(j)(5) entities, add a K‑1 mapping sheet so allocations land in the right boxes every time.
If your firm lives in QuickBooks and CCH Axcess or ProConnect for tax, add a simple index at the front of each PDF. It sounds small, but it saves real partner time during March and April.
Filing tips and common errors to avoid
- Do not mix buildings. File one Form 8611 per BIN and match the address and placed‑in‑service date to Form 8609.
- Do not skip the Line 2 worksheet. You must remove credits from post–first‑year additions before you compute the accelerated portion.
- Do not use 100 on Line 4 for a sale. Use the table on the form, set 1.000 on Line 6 when the decrease is full.
- Do not guess on interest. Use the IRC 6621 overpayment rates and apply daily compounding under IRC 6622, with a per‑year schedule.
- Do not push partner‑level 8611s when §42(j)(5) applies. Compute at the entity and allocate on K‑1.

Common Mistakes We See Every Season
Six mistakes show up on nearly every 8611 we review. Five come from sloppy documentation, one from misreading the table on Line 4.
Reusable Checklists
Each checklist below is built to drop into a firm SOP. Copy the markup, paste it into your engagement template, and adapt the wording to your software stack.
Pre-prep evidence packet
- Pull Form 8609 for each affected building and verify BIN, address, and placed-in-service date match Items C, D, and E on Form 8611.
- Pull every Form 8609-A filed during the compliance period and flag each year where line 7 was completed.
- Compile the current owner’s full Form 8586 history for the building, gross of the tax liability limit; exclude any credits taken by a prior owner.
- Identify the trigger in writing (qualified-basis decrease, disposition, set-aside failure, casualty within or outside a reasonable restoration period, or an at-risk change).
- For dispositions, document the “reasonable expectation of continued operation” test if you intend to rely on the recapture exception.
- Check whether the building is tax-exempt bond financed; if so, gather Item F data (bond-issuer name, date of issue, name of issue, and CUSIP or “None” if no CUSIP exists).
- If the decrease is at-risk driven, queue the IRC 42(k) recalculation memo before any Line 5 work begins.
Recapture math review (per building)
- Confirm Line 1 totals only the current owner’s prior-year credits, gross of the tax liability limit.
- Run the Line 2 Worksheet separately for each prior year that completed line 7 of Form 8609-A; in step b, multiply line 10 of Form 8609-A by 2.
- Select the Line 4 decimal from the year table: 0.333 for years 2 through 11, 0.267 in year 12, 0.200 in year 13, 0.133 in year 14, 0.067 in year 15. Carry to at least three decimal places.
- Enter 1.000 on Line 6 for a disposition without an avoidance exception or for a minimum set-aside failure; otherwise compute the percentage decrease in qualified basis to at least three decimal places, comparing first to any post-first-year additions.
- Reduce the Line 7 amount for any accelerated credits previously recaptured on the building so the same dollars are not recaptured twice.
- Compute Line 11 interest year by year at the IRC 6621(a)(1) overpayment rate with daily compounding, using Rev. Proc. 95-17 daily factors plus the quarterly IRB rates that apply after December 31, 2019.
- Aggregate Line 14 across all building forms and report the total on Schedule 2 (Form 1040), line 16 for individuals or Form 1120, Schedule J, line 9b for corporations.
Section 42(j)(5) partnership handoff
- Confirm the partnership has at least 35 partners; count each spousal pair and their estates as one partner.
- Complete Lines 1 through 7 at the partnership level; the partnership is treated as the taxpayer to which the credit was allowed.
- Compute Line 16 interest at the entity level, then total Lines 7 and 16 on Line 17.
- Attach Form 8611 to Form 1065 and allocate the Line 17 amount to partners on Schedule K-1 in the same ratio as taxable income.
- For partners receiving a section 42(j)(5) recapture amount, enter 0 on their Line 11 and write “Section 42(j)(5)” to the left of the entry space; the partnership has already included interest in the reported amount.
- Share Items C, D, E, and F data with every partner who receives an allocation.
- Retain copies of Forms 8586, 8609, 8609-A, 8611, and 8693 for three years after the 15-year compliance period ends.
Keep 8611 Season From Stalling
Form 8611 is a low-volume, high-stakes filing. Most firms see one or two recapture events in a given year, often tied to a November or December disposition or a compliance audit finding, and the file lands on a senior with a stale workpaper template and no live memory of the prior-year math. By the time the preparer reconciles the BIN trail across Forms 8586, 8609, and 8609-A, the partner review window is already shrinking.
The fix is not more hands on the file. It is a standing 8611 protocol the team can run when the trigger hits, with the per-building math, the per-year interest computation, and the K-1 allocations all separated into reviewable artifacts that the partner can sign off on without rebuilding the case from scratch.
- Anchor every workpaper to one BIN with the placed-in-service date and the elected set-aside test (20-50, 40-60, or average income) printed on the cover sheet.
- Lock the Line 4 decimal as a year-driven input from the published table so a preparer cannot type a flat 0.333 over a late-cycle year.
- Keep a year-by-year interest schedule referencing Rev. Proc. 95-17 daily factors plus the quarterly IRB rates that apply after December 31, 2019, with each prior year recaptured on its own row.
- For section 42(j)(5) partnerships, separate the entity-level Lines 1 through 7 and 16 through 17 from the K-1 partner-level reporting so the entity computation and the allocation are reviewed independently.
- Attach the trigger memo (disposition, set-aside failure, at-risk change, casualty restoration timing) to every Form 8611 workpaper so reviewers can audit the recapture path without rebuilding the underlying case.
Accountably handles the per-building prep, the per-year interest math, and the workpaper documentation so your team keeps partner-level review and the client conversation. See how the offshore prep model works on our U.S. tax outsourcing services page.
FAQs
When do I have to file Form 8611?
You file for any year in the 15‑year compliance period when the building’s qualified basis at year end is less than it was at the end of the prior year, or when you dispose of a building or an interest in it and you do not meet an exception. You file one form per building.
What recapture percentage do I use in the twelfth year?
Use 0.267 on Line 4 for year 12. For years 2–11 use 0.333, then 0.200 in year 13, 0.133 in year 14, and 0.067 in year 15.
How do I calculate the interest on Line 11?
Compute interest separately for each prior year at the IRC 6621 overpayment rate, with daily compounding under IRC 6622. Run interest from each original return due date to the earlier of the current return’s due date or the date you file and fully pay. Attach or retain the year‑by‑year support.
Does a sale always cause recapture?
A sale usually results in recapture unless you can document a reasonable expectation that the property will continue to be a qualified low‑income building for the rest of the compliance period. Keep the purchase agreement, extended use restrictions, and any buyer certifications with your file.
For a §42(j)(5) partnership, who files Form 8611?
The partnership computes the recapture and interest on Form 8611 and allocates amounts on Schedule K‑1. Partners do not file Form 8611 for that building.
