Here is the honest version of the calendar you came for.

• Annual owner certification — due to your state agency, at a date the agency sets.

• Utility allowance review — at least once each calendar year.

• Income limits — implement when the rule says, which is not a fixed date.

• Utility allowance implementation — 90 days after the change, which is not a fixed date either.

• Recertification and student status — on each household's own anniversary.

• Form 8609-A — annually with the return, by whoever files it.

Six entries. One of them is a date, and even that one is set by your agency rather than by the federal rules.

That is the problem with every printable LIHTC calendar you will find. Most federal deadlines here are triggers, not dates. They fire when something else happens, and a static calendar can only be right by accident.

Here is what actually drives each one, and what to build instead.

The Date That Moves Every Year

The clearest example is the income limits.

HUD releases income limits annually. Under Revenue Ruling 94-57, owners may rely on the previous year's limits until 45 days after HUD releases the new list, or until HUD's effective date for the new list, whichever is later.

Read the second limb. It is not simply 45 days from release. It is the later of two events, which means the implementation deadline depends on HUD's release date and HUD's stated effective date, both of which move.

What that produces in practice. Colorado's housing finance authority, publishing its annual guidance, set the implementation deadline at 16 May in 2024, 16 May in 2025, and 15 June in 2026.

Same rule, three different dates. A calendar with "implement new income limits" pinned to a fixed date in May can become wrong as soon as the underlying HUD schedule changes.

So the entry should not be a date. It should be a standing task: when HUD releases the new limits, calculate the deadline from the rule and diary it then.

The Rule Where Timing Runs From An Event

The utility allowance implementation has the same shape.

Where the applicable utility allowance changes, the new allowance must be used to compute gross rents due 90 days after the change, under 26 CFR 1.42-10.

Two things most calendars miss.

• The federal 90-day rule runs from the applicable change, not simply from the date someone at the property receives or notices the new allowance. The applicable agency or utility-allowance method should determine the operative date, and different methods have different procedural steps.

• The federal rule establishes a 90-day implementation period. Do not assume that receiving or calculating a new allowance authorises an earlier implementation date. State agency procedures may impose additional timing or notice requirements, and some state guidance is explicit that implementation should be neither earlier nor later than the end of that period.

The annual review is a genuine calendar-year obligation. The implementation timing is a trigger. They are two different entries and they are routinely merged into one.

The Dates That Belong To Households

A third category runs off individual households or units, which means it has as many dates as the project has applicable tenancy-level obligations.

1. Recertification anniversaries, where recertification applies. The federal relief for qualifying projects does not remove the initial certification, does not remove student status requirements, and does not override what a state agency may separately require.

2. Student status verification. For each low-income household subject to the requirement, track the anniversary of the original student-status verification rather than relying on a calendar-year reminder. IRS guidance says the verification should be completed within 120 days before that anniversary.

3. Rent-change restrictions tied to other programs or agreements. Some projects have additional rent-change timing or notice requirements under state rules, regulatory agreements, subsidy programs, or other financing documents. Those are project-specific triggers, not a universal federal LIHTC calendar entry.

None of these can sit in a shared calendar. They are per-household fields that generate dates, and flattening them into a January-to-December view will miss most of them.

The One Real Date, And Why It Is Not Yours

The annual owner certification is the closest thing to a fixed entry, and even it belongs to somebody else.

26 CFR 1.42-5(c) requires the owner to certify at least annually to the agency, covering the applicable minimum set-aside test and the other specified matters. The regulation sets the requirement. The agency sets the due date.

Many use 31 January. Not all do — some agencies operate a seasonal schedule tied to placed-in-service year, where 31 January applies to one group of projects and other groups report in April, July or October.

The same applies to monitoring review scheduling, which follows the agency's cycle, and to additional reporting, which varies. Some agencies require an annual self-certification of income even where federal recertification relief applies. Some require utility allowance documentation on a set schedule. Some require both.

The instruction here is simple and unpopular: for each state you operate in, find the agency's current compliance manual, note its date, and extract its deadlines into your own calendar. A national calendar cannot substitute for it.

What To Build Instead

Six entries, and none of them starts with a fixed annual date.

1. A standing task tied to HUD's release, not to a month. When the new limits come out, calculate the implementation deadline under the rule and diary it.

2. A per-building utility allowance record carrying the schedule's effective date, the calculated implementation date, the method used and the supporting document. The review is annual; the implementation date is derived.

3. A per-household field for recertification and student status anniversaries, generating its own reminders rather than sitting in a shared calendar.

4. A per-state sheet of agency-set deadlines, with the date of the manual you took them from. Refresh it annually, because manuals change.

5. A handoff point with whoever files the returns. Form 8609 is the building-level Low-Income Housing Credit Allocation and Certification issued by the housing credit agency, while Form 8609-A is the annual statement filed by the building owner during the 15-year compliance period. Both belong to the tax process rather than site compliance, and the handoff is where they go missing.

6. And a retention register, flagging first-year files separately. First-year credit period records carry a longer retention requirement than the rest, and a standard policy applied across the portfolio will delete them early.

That is not a calendar. It is a set of triggers with owners attached, which is what the regulations actually create. Keeping those against the building and the household rather than in a shared document is the difference between a system that holds and one that depends on somebody remembering.

The Test

Take last year. Pick the three dates that moved: the income limit implementation, any utility allowance change, and your agency's certification deadline.

Ask who calculated each one, and from what.

If the answer is that someone copied last year's calendar forward, the calendar is not tracking the rules. It is tracking itself, and it will keep being right until the year one of the underlying dates moves.

FAQ

1. When do new LIHTC income limits have to be implemented?
Under Revenue Ruling 94-57, owners may rely on the previous year's limits until 45 days after HUD releases the new list, or until HUD's effective date for the new list, whichever is later. The resulting deadline changes year to year.

2. When is the annual owner certification due?
26 CFR 1.42-5(c) requires certification at least annually to the state agency. The due date is set by the agency, and some agencies use a seasonal schedule rather than a single date, so confirm it in your state's current compliance manual.

3. When must a new utility allowance be implemented?
The new allowance must be used to compute gross rents due 90 days after the change. The operative date for the change depends on the applicable agency and utility-allowance method, and state procedures may add timing requirements.

4. How often must utility allowances be reviewed?
At least once during each calendar year, subject to the first-year occupancy rule for new buildings.

5. When is student status verified?
IRS guidance says the verification should be completed within 120 days before the anniversary of the original student-status verification, which makes it a per-household date rather than a calendar-year task.
