Construction, the 10% test, and getting to 8609 — Missouri

The clocks you are now running against

This phase starts once the Firm Commitment is signed and the Carryover Allocation Agreement is executed — the calendar stops being about scoring and becomes a pure function of that execution date. Missouri's clock runs off a single document, the Federal Carryover Allocation Agreement, not the earlier Conditional Reservation or the later closing, so the effective date on that one agreement is what every other deadline in this phase counts from.

The unit of measure matters the same way it does under the federal statute everywhere. The placed-in-service deadline is a calendar-year boundary, not a rolling 24-month window. A Carryover Allocation executed in December gets barely more than a year of practical runway to place the last building in service by the following year's close; one executed in January gets nearly a full extra year on the same nominal "second calendar year" rule. Schedule against the actual December 31 date, not a mental "2 years from Carryover."

No published, Missouri-specific distribution of construction, lease-up, or Carryover-to-8609 durations was located for this guide. MHDC's internal award data may exist, but nothing publicly available joins Carryover Allocation dates to placed-in-service or 8609-issuance dates the way a defensible duration benchmark would require. Schedule this phase against your own completed-deal history in Missouri, not an imported range from another state's practitioner folklore.

The 10% Test: what MHDC actually requires

The federal standard is the one every state applies: the taxpayer's basis in the project as of the date one year after the Carryover Allocation must exceed 10 percent of the reasonably expected basis as of the close of the second calendar year following the allocation year (IRC Section 42(h)(1)(E)(ii)). MHDC doesn't layer a separate timing rule on top of the statute the way some states' own regulations do — it requires the same 12-month showing, with a one-month grace period for the paperwork to actually reach MHDC's desk.

There's a second "10 percent" in Missouri's process that has nothing to do with this test, and the two are easy to conflate. The "Maximum Credit Amount" the Commission can award without additional Board approval is the Initial Approval Amount plus 10 percent of that amount — a credit-increase ceiling, not a basis-incurred test. Clearing the 10% Test says nothing about whether a later credit increase falls inside that separate 10 percent cushion, and staying under the Maximum Credit Amount says nothing about whether the 10% Test itself has been met.

MHDC's carryover language is also more open-ended about consequences than an enumerated relief list would be. Missing the 10% Test triggers recapture, and MHDC staff "may, in its sole discretion, rescind the Carryover Allocation and use the recaptured credits for other developments" — full stop. Nothing in the 2027 QAP names the circumstances in which that discretion will be exercised leniently.

A second state agency runs the bond track

On a 4% bond deal, MHDC is not the only agency in the room. MHDC allocates the LIHTC and makes the federal Section 42(m) determination of credit necessity, but the private activity bond volume cap that makes the 4% Credit possible at all is allocated separately by the Missouri Department of Economic Development (DED), under its Private Activity Bond Allocation Program. A 4% deal has to clear both agencies' processes, on two different tracks, before it closes.

To earn the full 4% Credit on a bond deal, a development's eligible basis has to be sufficiently financed by the tax-exempt bonds — and the currently adopted 2027 QAP (adopted December 9, 2025) does not state that threshold as any specific percentage at all; it does not restate an aggregate-basis figure anywhere in its own text, a change from the outgoing 2027 QAP, which had stated a 50 percent test directly. Only MHDC's 2027 Developer's Guide states a figure, and it states 25 percent. Federal law itself preserves both numbers: IRC § 42(h)(4)(B), as amended in 2025, leaves the original 50 percent test in place at any time, and separately added a lower 25 percent alternative that a development can use only if at least one bond within the issue (1) has an issue date after December 31, 2025, and (2) itself finances at least 5 percent of the building's aggregate basis. In practice, a deal whose bonds are all issued before that date has only the 50 percent path available; one with a qualifying post-2025 bond tranche can use the easier 25 percent path instead — but the 50 percent path never goes away, and the 25 percent path isn't automatic just because the calendar turned. Because the QAP itself is silent, the Developer's Guide's 25 percent figure and the amended statute are the only two places to check — not a QAP citation that no longer exists.

What this guide could not independently confirm is a Missouri-specific statutory or administrative citation for the deadline to close bonds once DED issues a volume-cap reservation, or for a carryforward election procedure comparable to what other states publish. DED's own program page describes the application cycle and the cap amount but does not itself state a closing deadline or carryforward mechanism; that detail likely lives in the individual reservation letter DED issues, or relies on bond counsel's own tracking of the federal three-year carryforward rule, rather than in a published Missouri rule this research located.

Placing in service is a filing event, not a construction event

A certificate of occupancy gets a Missouri deal nothing on its own. MHDC will not issue IRS Form 8609(s) or the Missouri Eligibility Statement — "no exceptions will be made" — until every item on a nine-point list is satisfied, and the list runs well past "the building is done."

Then the federal step every state's owners forget. The owner must certify first-year information to the IRS following the close of the first taxable year of the credit period, and no credit is allowable for any taxable year ending before that certification is made (IRC Section 42(l)(1)). Missouri adds its own enforcement hook behind that federal rule: a copy of the executed Form 8609 Part II, as filed with the IRS, must reach MHDC's Asset Management Department within 90 days after the end of the first credit-period year. If MHDC never receives it, the property doesn't get the benefit of the doubt — it's required to remain in the compliance-monitoring program through December 31 of the 16th year after the date the final building was placed in service, regardless of when the actual 15-year compliance period would otherwise have run out.

One more milestone sits inside this window for any development built with MHDC construction-loan financing: the Latent Defect Inspection. MHDC inspects the property for latent defects within nine months of the reported final construction date, and the owner or general contractor has 45 days from the inspection report to document that cited deficiencies have been corrected — failure results in an IRS Form 8823. This is a construction-loan-financed requirement, not a universal Missouri LIHTC milestone; a 4% bond deal financed entirely outside MHDC's own loan programs may not run through the same LDI process an MHDC-financed 9% deal does.

Lease-up decides the credit, permanently

The core mechanic is identical to every other LIHTC state because it's federal, not state, law: qualified basis is the applicable fraction times eligible basis, and the applicable fraction is redetermined as of the close of every taxable year, not frozen once and forgotten (IRC § 42(c)(1)); the credit for the first year of the credit period is itself specially prorated based on how many full months each unit was actually in service that year (IRC § 42(f)(2)). A household that was never income-qualified at initial occupancy makes that unit non-qualifying for as long as it stays occupied by that household — depressing the applicable fraction in every year that follows — and the only cure is a Next Available Unit Rule transfer to a qualifying household (IRC § 42(g)(2)(D)), not the passage of time. A lease-up mistake is not a one-year cost; it re-bills itself every year until it's actually fixed.

The LURA carrying that 30-year minimum has to be recorded ahead of construction financing, not after. Federal law requires the extended low-income housing commitment to bind even through foreclosure or a deed in lieu of foreclosure for a three-year tail (IRC Section 42(h)(6)(E)(ii)), and MHDC's practice has the title company record the LURA before any deed of trust or other first-lien encumbrance — the priority recording is what makes that federal tenant-protection tail enforceable against later lienholders.

Full-time student status has to be checked for every household, and it doesn't relax just because a property is 100 percent affordable. A household in which every member is a full-time student is not LIHTC-eligible, subject only to five narrow statutory exceptions referenced against IRC Section 152 (married couples entitled to file jointly, single parents with a dependent child not claimed by another taxpayer, students receiving TANF assistance, and similarly specific carve-outs).

One federal compliance change Missouri has already absorbed, where other states are still phasing it in: MHDC's compliance guidance treats HOTMA's Section 102 income-review provisions as in effect for LIHTC, HOME, and National Housing Trust Fund units since January 1, 2024, with its own MHDC HOTMA Manual already published. A building leasing up now is not waiting on a future mandatory date the way it might be elsewhere — Missouri's version of that requirement is already live.

Missing a date, and the narrow ways out

Missouri's QAP does not publish anything resembling an enumerated relief list. There's no Reservation Exchange-style catalog of qualifying circumstances and no Force Majeure provision with defined proof requirements. What exists instead is a single sentence of open-ended agency discretion: MHDC retains the right, "in its sole discretion," to modify or waive any provision of the QAP not required by the Code, and to rescind a Carryover Allocation and reallocate the recaptured credits when conditions and deadlines aren't met. That gives a developer facing a genuine hardship somewhere to ask — but nothing in the published QAP says in advance what MHDC will actually accept.

The Correction Period itself is capped at 90 days from the date MHDC sends a notice of noncompliance, and MHDC may extend it up to six months — but only where MHDC determines there is good cause, the same undefined-discretion pattern as the Carryover Allocation deadlines (2027 QAP, "Compliance Monitoring").

A separate, construction-phase-specific exposure sits outside Section 42 entirely. MHDC's Workforce Eligibility Policy requires every contracting party performing labor on an MHDC-funded development — LIHTC deals included — to enroll and actively participate in E-Verify, and every person performing construction labor must complete OSHA-10 training within 60 days of starting work. A violation is sanctioned independently of any tax-credit compliance issue: suspension or revocation of MHDC funding, rescission of tax credits, and suspension and debarment from MHDC programs, citing Mo. Rev. Stat. Sections 285.530(1), 285.233, 285.234, 285.500 through 285.515, and 285.550.

There's also a slower-moving consequence that never shows up as a point deduction on this application, only on the next one. MHDC's scoring evaluates "performance regarding MHDC deadlines for previous funding awards, including significant cost increases, additional funding requests, responsiveness, timeliness, adherence to MHDC requirements, and overall performance of previously funded properties" as part of every future application's Development Team Characteristics review, and any team member "not in good standing with MHDC or its programs will not be approved for funding." A missed deadline on this deal is underwriting risk on the next one.

What the sources do not settle

Four things are genuinely open here, and a Missouri schedule built on this phase should treat them as inputs, not settled facts.

No verified Missouri-specific construction, lease-up, or Carryover-to-8609 duration benchmark exists. Nothing publicly available joins MHDC's Carryover Allocation dates to its own placed-in-service or 8609-issuance dates the way a defensible distribution would require.

MHDC's own internal processing time — from a complete cost certification and Tax Credit Issuance checklist submission to actual 8609 issuance — is not published. That gap sits directly between the final construction draw and the investor's first-year credit.

Whether MHDC's "sole discretion" language has produced any consistent, predictable pattern of relief for good-faith construction delays — weather, supply chain, a lender default — was not something this research could confirm one way or the other. No published guidance, memo, or precedent list was located describing what MHDC has actually granted in practice.

A Missouri-specific statutory or administrative citation for the deadline to close bonds after a DED volume-cap reservation, and for any carryforward election procedure, was not located in the documents reviewed for this guide. That detail may sit in DED's individual reservation letters or rely entirely on the federal carryforward rule, rather than in a published Missouri rule.
