Year-end for a Low-Income Housing Tax Credit property isn't one deadline.

It's three documents, going to two different authorities, on different clocks. One is submitted once. One is filed every year for fifteen years. And one is signed by the owner under penalties of perjury, covering twelve months of tenant files, rents, inspections and occupancy decisions that someone else usually made.

Most LIHTC obligations don't fall on fixed dates at all. They're triggered by events, as we explained in the LIHTC compliance calendar that does not exist. Year-end is where the few filings that do recur sit, and it's where the rest of the year's records get tested.

That last point is the one worth dwelling on. The owner signs. The property management team produces the evidence. When the two are disconnected, the signature is only as reliable as a spreadsheet assembled in January.

LIHTC is a US federal program under Section 42 of the Internal Revenue Code. This article is operational guidance for property management teams, not tax or legal advice. Filing positions, elections and credit calculations should be handled with the owner's tax advisors, and each state housing credit agency sets its own procedures.

Three documents, two authorities

The first two are federal tax filings, usually prepared with the owner's tax advisors. The third is where property management carries most of the weight, because almost every item on it is a statement about operations.

Form 8609: the one-time filing that sets the rules for fifteen years

The IRS instructions for Form 8609, revised December 2025, describe a split form. The housing credit agency completes and signs Part I, which records the allocation, and sends the original to the owner. A separate Form 8609 is issued for each building.

The owner then completes Part II, the first-year certification, and makes a one-time submission of the form to the IRS's Low-Income Housing Credit Unit in Philadelphia, no later than the due date, including extensions, of the first tax return filed with Form 8609-A. The IRS notes that the agency may require its own copy of the completed Part II, and that the copy sent to the agency should match the one filed with the IRS.

Part II is short, but several of its answers can't be changed later, and some of them shape how the property must be operated for years.

Line 8b has a practical consequence many teams discover late. At least one state manual notes that if a property didn't elect multiple building project status, a tenant moving between buildings must be treated as a new move-in. A tax election made in year one quietly governs a transfer request in year nine.

Form 8609-A: every year for fifteen years

After the first year, the annual federal filing is Form 8609-A. The IRS describes it as the form a building owner uses to report compliance with the low-income housing provisions for each year of the 15-year compliance period and to calculate the credit. The credit itself is claimed on Form 8586.

Form 8609-A draws on the building's annual compliance and financial information, including its qualified basis and applicable fraction. Property records provide much of the underlying information used to determine those figures, while the owner's tax team handles the tax calculations and filing. If the building's applicable fraction changed during the year, that change can affect both the annual filing and the owner certification.

The annual owner certification: twelve statements about the last twelve months

The owner certification is administered by each state or local agency, under a federal framework. 26 CFR 1.42-5 requires each agency's compliance monitoring procedure to require owners to certify at least annually, under penalties of perjury, covering the preceding twelve-month period. Agencies call the document different things, often an Annual Owner's Certification or Owner's Certificate of Continuing Program Compliance, and many require tenant and unit data alongside it.

Here is what the regulation requires owners to certify, mapped to the records that have to exist for the statement to be true.

Two items deserve particular attention because they're often treated as someone else's problem.

Habitability is on the owner's certification. The owner must state whether a local code violation report was issued, attach a summary or copy if one was, and say whether it has been corrected. Maintenance records are therefore compliance records. Preventive programs and life-safety schedules, which we covered in our annual preventive maintenance calendar and the life-safety inspection schedule, feed directly into a signature.

Fair housing is on it too. A finding of discrimination is part of what the owner certifies against. Leasing practice, including how units are advertised, belongs in the compliance picture, a topic we covered in the fair housing word list you're using hasn't been a federal rule for 30 years.

When it's due depends on the agency. There's no single national due date. Washington, DC's housing agency set May 11 for 2026 certifications, with June 1 as the date after which failure to submit could lead to a notice of noncompliance or an IRS Form 8823, while New York City's HPD reviews certifications submitted by March 1. Others use different dates or seasonal schedules. For a portfolio spanning several states, that means several deadlines, each with its own format and reporting period, and year-end work that has to start in the fourth quarter.

What happens when something's wrong

The regulation sets out the path. When an agency doesn't receive the certification, can't review the required records, or finds noncompliance, it must notify the owner in writing. The owner then has a correction period set by the agency, not exceeding 90 days from the notice, which the agency may extend by up to six months for good cause.

The agency must then file Form 8823 with the IRS, reporting the noncompliance, no later than 45 days after the correction period ends, whether or not it has been corrected, and indicating whether it was. A missing owner certification is itself a reportable failure.

What that means for the owner's credits depends on the nature of the noncompliance and is a question for tax advisors. For property management, the lesson is simpler: the correction period is short, and the report goes to the IRS either way.

Records you'll be asked to keep

Record retention runs longer than most teams expect. The regulation requires agencies' procedures to require owners to keep the compliance records for at least six years after the due date of the tax return for each year. Records for the first year of the credit period must be kept for at least six years beyond the due date of the return for the last year of the compliance period. The IRS separately asks owners to keep their Forms 8609, 8609-A and 8586 for three years after the due date of the return for the year that includes the end of the 15-year compliance period. Agencies may set longer requirements.

In practice, that means tenant files and first-year records from a building's opening year need to be retrievable more than two decades later, often after management companies have changed.

A fourth-quarter checklist for property management

1. Reconcile the rent roll to the tenant files. Every low-income unit should have a current income certification, where required, with supporting documentation.

2. Check rents against the current limits, including utility allowances. When new income limits and allowances take effect is triggered by events rather than fixed dates, as covered in the LIHTC compliance calendar that does not exist.

3. Recount the applicable fraction by building, and flag any change.

4. Review vacancies and move-ins. Confirm the next available unit rule was followed, especially where a tenant's income rose above the allowed limit.

5. Collect code violation notices and evidence of correction for the period.

6. Confirm no fees were charged for tenant facilities included in eligible basis.

7. Note any change in use of common or nonresidential space.

8. Confirm each agency's certification deadline, period and format, and whether it needs tenant-level data.

9. Hand the numbers to the tax team for Form 8609-A.

10. For buildings in their first credit year: coordinate Part II of Form 8609, including the multiple building project statement if applicable, and the one-time IRS submission.

Frequently asked questions

Q1. What is Form 8609?
The Low-Income Housing Credit Allocation and Certification form. The state or local housing credit agency completes Part I to record the allocation for each building, and the owner completes Part II for the first year of the credit period, then makes a one-time submission of the form to the IRS.

Q2. What is the difference between Form 8609 and Form 8609-A?
Form 8609 is submitted to the IRS once, by the due date of the first return filed with Form 8609-A. Form 8609-A is filed every year of the 15-year compliance period to report compliance and calculate the credit.

Q3. What does the LIHTC annual owner certification include?
Under 26 CFR 1.42-5, agencies must require owners to certify, for the preceding twelve months, that the project met its set-aside test, whether the applicable fraction or eligible basis changed, that income certifications were received where required, that units were rent-restricted and suitable for occupancy, that fair housing and general public use requirements were met, and that vacancy and next available unit rules were followed, among other items.

Q4. When is the LIHTC owner certification due?
Each state or local agency sets its own deadline and format. For example, New York City's HPD uses March 1, and for 2026 Washington, DC's housing agency set May 11. Check each agency's current requirements.

Q5. What happens if the owner certification is late?
The agency must notify the owner and allow a correction period of up to 90 days, extendable for good cause. The agency then reports the failure to the IRS on Form 8823, whether or not it has been corrected.

Q6. How long must LIHTC records be kept?
Under the regulation, at least six years after the due date of the return for each year, and first-year records for at least six years beyond the due date of the return for the last year of the compliance period. Agencies may require longer.
