Construction, the 10% test, and getting to 8609 — New Jersey

The clocks you are now running against

This phase starts once NJHMFA has issued a reservation and executed a carryover allocation agreement. From that execution date — not the reservation date, and not the calendar year of the award — four deadlines run, and NJHMFA states plainly that it "reserves the right to rescind a reservation if a deadline is not met."

Note what the clock is actually pinned to. NJHMFA's rule text ties both the 10-percent test and the placed-in-service deadline to the date it executes the carryover allocation agreement, which typically follows the November 30 filing deadline — not to the reservation announcement and not automatically to the calendar year the credits were reserved. Two projects reserved in the same cycle can end up with different placed-in-service dates depending on when each one's carryover paperwork actually got signed.

The 10% test: NJHMFA runs the six-month clock, not the statute's twelve

The federal statute sets the outer bound: the taxpayer's basis in the project one year after the allocation must exceed 10 percent of reasonably expected basis as of the close of the second calendar year following the allocation year (26 U.S.C. § 42(h)(1)(E)(ii)). But the Treasury regulation implementing that test was never amended after the 2008 HERA amendment moved the statutory deadline to a uniform 12 months — 26 CFR Section 1.42-6(a)(2) still says an allocation made before July 1 must meet the test by the close of that calendar year, and an allocation made after June 30 must meet it within six months. NJHMFA's QAP adopts that six-month figure directly as its own operative rule, without qualification (N.J.A.C. 5:80-33.24(a)). A developer arriving from a state that implements the statute's 12-month reading will be caught short if they schedule against that number instead of NJHMFA's six months.

The NJHMFA form evidencing satisfaction of the test must be completed and certified by an independent certified public accountant (N.J.A.C. 5:80-33.24(a)). Two conditions specific to New Jersey's carryover mechanics attach to it.

NJHMFA's own regulation does not restate the federal mechanics of what counts toward the numerator; those govern by default because the QAP is required to be "construed and administered in a manner consistent with the Code" (N.J.A.C. 5:80-33.1(e)).

Miss NJHMFA's November 30 filing deadline for the underlying carryover package itself, and there is a defined cost: NJHMFA may extend on a case-by-case basis "if the owner can show good cause," but charges $1,000 for each week or part thereof the owner is late, and reserves the right to rescind the reservation outright if the deadline is not met (N.J.A.C. 5:80-33.24(a)).

The volume-cap (4%) track shares NJHMFA's own calendar — there is no separate bond agency

Unlike states that split competitive 9% credits and tax-exempt-bond 4% credits between two agencies, NJHMFA is the housing credit agency for both. If NJHMFA is the bond issuer, it makes the Section 42(m)(2)(D) credit-need determination itself; if a different entity issues the bonds, that issuer must send NJHMFA a letter assigning it that responsibility (N.J.A.C. 5:80-33.9(a)1). There is no separate performance-deposit regime in the QAP for the bond track — NJHMFA's leverage runs through the non-refundable allocation/issuance fee and the negative-points system described below.

One federal input to that 50 percent figure changed after NJHMFA's QAP was last written. The One Big Beautiful Bill Act (Pub. L. 119-21, § 70422(b)(1), enacted July 4, 2025) rewrote 26 U.S.C. § 42(h)(4)(B) to add a second, lower path: 25 percent or more of the aggregate basis financed with tax-exempt bonds now satisfies the volume-cap requirement instead of 50 percent, provided at least one qualifying bond is part of an issue dated after December 31, 2025 and finances at least 5 percent of the aggregate basis. NJHMFA's 2026 QAP, adopted February 2, 2026, states only the flat 50 percent figure at N.J.A.C. 5:80-33.9(a)2 and does not mention the alternative — whether NJHMFA will administer the lower federal threshold or hold applicants to 50 percent as a matter of state policy is not addressed anywhere in the QAP text, and is worth confirming directly with NJHMFA and bond counsel before sizing a bond issuance around the lower figure.

The federal bond-timing traps that catch deals elsewhere apply the same way here, purely as federal law — NJHMFA's QAP does not restate them. Predevelopment spending before the issuer's official-intent resolution generally cannot be reimbursed from bond proceeds unless paid within 60 days beforehand (26 CFR § 1.150-2(d)(1)), and a TEFRA public approval is timely only within one year of the bond issue date (26 CFR § 1.147(f)-1(f)(7)). These are bond counsel's problem to police, not NJHMFA's, but they land on the same file.

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

NJHMFA completes Part I of Form 8609 only after it has received the full request package, conducted its evaluation (including the placed-in-service needs analysis), collected the fee, and the owner or a representative has attended an NJHMFA-sponsored compliance monitoring seminar (N.J.A.C. 5:80-33.26(a)). A certificate of occupancy alone gets a developer nothing.

Then the federal step people 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 year ending before that certification is made (26 U.S.C. § 42(l)(1)). Separately, NJHMFA requires a copy of the completed Form 8609 — Part I completed by NJHMFA, Part II by the owner — within 30 days of filing it with the IRS; missing that window "may constitute noncompliance and may be reported by NJHMFA to the IRS" (N.J.A.C. 5:80-33.32(a)).

Failure to fulfill application representations more broadly can delay or block issuance outright, and NJHMFA's penalty range runs from a financial penalty or credit reduction sized to the violation up to unilateral cancellation of the allocation for severe or persistent violations (N.J.A.C. 5:80-33.26(c)).

Lease-up decides the credit, permanently

Qualified basis and applicable fraction are fixed at the end of the first credit year (26 CFR § 1.42-5(b)(1)(viii)) — a household who shouldn't have qualified, occupying a unit in year one, permanently reduces the applicable fraction for the life of the compliance period.

New Jersey layers on post-construction energy reporting that has no equivalent in the federal rules: new construction projects owe whole-building aggregate utility data for the first three years of occupancy; rehabilitation projects owe one year of data before renovation and two years after, for all common areas and units (N.J.A.C. 5:80-33.12(c)8ii(3)).

For projects of 25 units or more, affirmative marketing is not just a plan on paper — it requires registering the project on the New Jersey Housing Resource Center and posting vacancies, waitlist openings, and lottery drawings, with the owner and rental agent certifying affirmative marketing at the time units are placed in service (N.J.A.C. 5:80-33.12(c)15; N.J.S.A. 52:27D-321.3 et seq.).

Missing a date, and the narrow way out

New Jersey's only named relief from the placed-in-service deadline is the Exchange of Credits, and it is narrower than the enumerated lists other states publish — just two qualifying circumstances, both requiring the Tax Credit Committee's satisfaction.

To qualify, the sponsor must show due diligence toward the original deadline, the specific circumstances causing the delay, and remedial measures attempted (N.J.A.C. 5:80-33.37(b)). The project must also meet current Energy Star requirements and score at least 65 percent of the maximum points under the QAP in effect when the exchange is requested (N.J.A.C. 5:80-33.37(c)). The request itself is due no later than November 1 of the year the project was originally required to place in service (N.J.A.C. 5:80-33.37(f)). A sponsor who receives an exchange — along with any affiliate or related party — is barred from applying for tax credits for a new project for the cycle round following Committee approval, and only one exchange is permitted per project (N.J.A.C. 5:80-33.37(d)–(e)).

New Jersey's real penalty for a bad Phase 10 outcome isn't a same-deal point deduction the way some states structure it — it's a scoring penalty that follows the sponsor into its next New Jersey LIHTC application.

NJHMFA re-runs its needs analysis three times — application, allocation, and placed in service — and "any substantive changes to the project's financing plan or costs shall be explained in detail and may cause the project to be reconsidered" (N.J.A.C. 5:80-33.23). A deal that repriced hard between reservation and carryover close is a re-underwriting risk, not just a budget problem.

What the sources do not settle

A few things are genuinely open, and a schedule built on this phase should treat them as inputs rather than knowns.

No New Jersey-specific distribution of real construction and lease-up durations was located in this research — not even the kind of unverified practitioner-folklore range that circulates for other states. NJHMFA publishes reservation and allocation-award data through its LIHTC Dashboard and allocation-awards archive; joining those to placed-in-service and 8609 dates could produce a defensible empirical distribution, but nobody appears to have assembled it publicly.

NJHMFA's own processing time from a complete 8609 request-package submission to signed 8609 issuance is not published anywhere this research located. That gap sits directly between the final cost certification and the investor's last equity installment.

The QAP text is silent on HOTMA and NSPIRE — no NJHMFA guidance memo equivalent to what other state agencies have issued on either was found in this research. Properties that layer HUD project-based rental assistance on top of LIHTC will pick up HOTMA and NSPIRE obligations directly from HUD, on HUD's own implementation timeline, independent of anything NJHMFA's QAP currently addresses.

The QAP's own penalty provision at N.J.A.C. 5:80-33.26(c) cross-references "minimum expenditures pursuant to N.J.A.C. 5:80-33.15(a)6" as an illustration, but 5:80-33.15(a)6 as adopted in the current QAP (effective February 2, 2026) governs M/WBE ownership-interest points, not an expenditure threshold. That reads as a stale internal cross-reference rather than a live requirement — worth confirming with NJHMFA counsel directly rather than assuming away, and not something this guide treats as a citable expenditure rule.
