01
A project needs capital.
Affordable rents often cannot support the full cost of acquiring, building or rehabilitating housing.
LIHTC explained
A tax credit became America's affordable-housing workhorse.
LIHTC is powerful because it brings private investment into affordable rental housing. Its weakness is that financing the building and preserving affordability forever are not the same job. Understanding that distinction makes the entire system easier to see.
The short version
LIHTC stands for the Low-Income Housing Tax Credit. Congress created it in 1986. Instead of the federal government simply writing a construction check, the program gives federal tax credits to qualified affordable-housing developments. Those credits are usually sold to investors, whose equity helps finance the project.
LIHTC solved a financing problem. It did not automatically solve the permanence problem.
The federal credit has a 10-year credit period and a 15-year compliance period. For post-1989 projects, federal law generally requires an extended-use commitment that reaches at least 30 years — but states and individual deals can require much longer terms. That is why “Year 30” is a preservation milestone, not a universal legal expiration date for every building.
02
The project receives tax credits.
A state housing credit agency allocates or administers LIHTC under federal rules and its own Qualified Allocation Plan.
03
An investor provides equity.
Investors buy an ownership interest and receive the tax credits and associated tax benefits, reducing the project's need for debt.
04
The property accepts restrictions.
Qualified units must meet income and rent rules, plus whatever longer state/local financing and regulatory commitments apply.
What are the 4% and 9% credits?
They are two financing pathways inside LIHTC. They are not “4%, 9%, or regular LIHTC.” If a database does not identify which type a property used, the honest category is unknown.
4%Often paired with tax-exempt bond financing
- Basic idea
- The 4% credit generally supports projects using federally tax-exempt private-activity bonds. It was historically designed around a smaller present-value subsidy than the 9% credit.
- How New York uses it
- New York HFA frequently uses 4% LIHTC with tax-exempt bond financing; 4% projects can also have other HCR, HPD/HDC or local financing layered into the deal.
- Why we care
- 4% projects can be large and increasingly important to production. Their final affordability term depends on the actual financing/regulatory structure, not the “4%” label alone.
9%Competitively allocated from a state's annual authority
- Basic idea
- The 9% credit generally provides more equity relative to qualified development costs and is commonly awarded through a competitive state allocation process.
- How New York uses it
- DHCR/HCR administers New York's primary 9% program through its QAP and annual multifamily finance competition.
- Why we care
- The state can use allocation rules and term sheets to demand public benefits that go beyond the federal floor — including longer affordability commitments.
A terminology note:
The tax-credit rates are often called “4%” and “9%,” although federal law and rate-floor rules are more technical than the names suggest. For tenants, the practical question is not the tax math; it is what financing and regulatory agreements came with the project and how long those agreements last.
Why do people talk about Year 10, Year 15 and Year 30?
Because several clocks are running at once. Mixing them together is one of the biggest sources of LIHTC confusion.
10
Credit period
The owner/investor claims the LIHTC over a 10-year credit period.
15
Federal compliance period
Owners report compliance through the 15-year federal compliance period. Year 15 is also a major partnership/investor-exit and recapitalization milestone.
30+
Extended use
For post-1989 projects, the federal extended-use period generally reaches at least 30 years. The housing credit agency can require a longer period.
?
Actual governing term
The final answer for a building may be 30, 40, 50, 60 years or another term depending on state/local requirements, financing layers, later preservation deals and recorded agreements.
Does affordability end at Year 15?
Usually, no. Year 15 is a major compliance and ownership/finance milestone. It is not the standard federal extended-use endpoint for post-1989 LIHTC projects.
Does every LIHTC building become market rate at Year 30?
No. Some agreements are longer. Some buildings are preserved or resyndicated. Other subsidies or rent protections may remain. A building-specific document review is necessary.
Then why should tenants care about a 30-year warning?
Because a preservation milestone can change an owner's options, financing strategy or incentives. Early research creates time to organize and influence what happens next.
Can a building receive LIHTC more than once?
Yes. Older LIHTC properties are often recapitalized or resyndicated using new credits and financing for rehabilitation, which can create a new affordability commitment.
LIHTC may be only one layer protecting a home.
A single property can have LIHTC plus Section 8, HOME, an HPD/HCR regulatory agreement, a tax-benefit restriction, rent stabilization, a later preservation transaction, or another covenant. Those layers can have different terms.
Think of a building as a Protection Stack.
If LIHTC reaches an important milestone, the right question is not simply “Did LIHTC end?” It is: What protections still apply to this building and this apartment today?

LIHTC partnerships are often structured so the original tax-credit investor can exit after the federal compliance period. That can lead to several very different outcomes: a nonprofit sponsor may buy out the investor; the property may refinance; the owner may resyndicate with new LIHTC for rehabilitation; the property may be sold; or the ownership structure may become contested.
What happens when an affordability term approaches its end?
There is no one outcome. A mission-driven owner may preserve the property. A for-profit owner may preserve it too — or may have a financial incentive to seek a less restricted future. Government may refinance or acquire the property. Tenants may have rights under another program. A purchase-right law may create leverage if the building is sold. The point of Affordable Forever is to find the building early enough to learn which path is actually developing.
The preservation question is not “Will every building be lost?”
It is: Why should tenants, organizers and public agencies discover the answer at the last possible moment? An early-warning system gives people time to verify the governing documents, organize, secure preservation capital, exercise purchase rights, negotiate an extension, or demand a better public bargain.
The policy question: what should the public get for the subsidy?
LIHTC is indispensable to today's affordable-housing system. Affordable Forever's argument is not “abolish the financing tool.” It is: keep the tool, improve the bargain.
Frequently asked questions
Is LIHTC a voucher?
No. LIHTC primarily finances the property. A tenant in a LIHTC unit may separately have a voucher or live in a property with project-based rental assistance.
Are LIHTC rents based on my individual income?
LIHTC generally sets maximum rents using program income/rent formulas tied to area median income and unit assumptions, not simply a fixed percentage of each individual tenant's actual income. Rental assistance can change what a particular tenant pays.
If my LIHTC record says “Inactive,” am I unprotected?
Not necessarily. “Inactive” describes the LIHTC record in the source database. Other affordability agreements, rental assistance, tax benefits or rent regulation may still apply. Verify the Protection Stack.
If my building is nonprofit-owned, is it safe?
Nonprofit ownership is generally a useful preservation signal, but it is not a guarantee. Nonprofits can refinance, sell, restructure or face financial pressure. Organizers should still verify the plan and governing agreements.
If my building is for-profit-owned, does that mean it will convert?
No. Many for-profit owners preserve affordable housing. But ownership type can affect incentives, so a for-profit property approaching a preservation milestone deserves closer research rather than an automatic conclusion.
Why doesn't Affordable Forever just show “the expiration date”?
Because the public dataset often does not contain the controlling legal date. Showing an estimate as certainty would be misleading. We show the early-warning signal and are building a separate verified-research layer for governing documents.

You do not need to memorize any of this. Search your address, understand the warning signal, and organize early enough to learn the real protection picture together.
