Low-Income Housing Tax Credit (LIHTC) Rentals: Tenant and Landlord Rules

The Low-Income Housing Tax Credit program governs a large segment of the subsidized rental market in the United States, establishing binding obligations on both property owners and residents that differ substantially from standard market-rate tenancy. Administered through the Internal Revenue Code and implemented by state housing finance agencies, LIHTC creates a compliance framework that persists for a minimum of 30 years per property. Understanding how this framework operates is essential for landlords managing tax credit properties, tenants seeking or occupying affordable units, and researchers examining the landscape of landlord-tenant relationships across the country.

Definition and scope

The Low-Income Housing Tax Credit was established under Section 42 of the Internal Revenue Code, enacted as part of the Tax Reform Act of 1986. The program allocates federal tax credits to developers who build or rehabilitate rental housing reserved for households below specified income thresholds. Credits are not grants — they are dollar-for-dollar reductions in federal tax liability claimed over a 10-year period by investors in qualified projects.

The Internal Revenue Service administers the tax credit itself, while allocation authority rests with state housing finance agencies (HFAs), which distribute credits according to annual Qualified Allocation Plans (QAPs). The total national credit authority is capped by statute. Under 26 U.S.C. § 42, each state receives a per-capita allocation; in 2023, the per-capita amount was $2.75 per resident, with a small-state minimum of $3,185,000 (IRS Revenue Procedure 2022-38).

Two credit rate categories apply: the 9% credit (used for new construction or substantial rehabilitation not federally subsidized) and the 4% credit (used for acquisitions or projects financed with tax-exempt bonds). These rates are not fixed percentages of the credit amount — they reflect the applicable percentage set monthly by the IRS to produce a present value equal to 70% or 30% of qualified basis, respectively.

How it works

LIHTC compliance operates through a layered regulatory structure involving federal requirements, state QAP conditions, and recorded land-use restriction agreements (LURAs) that bind successive property owners.

Core compliance sequence:

1. Application and allocation — A developer applies to the state HFA, which scores proposals against QAP criteria covering location, affordability depth, and design standards.
2. Placed-in-service certification — Once a project reaches occupancy thresholds, the owner submits IRS Form 8609 to establish the credit basis and elected set-aside.
3. Initial qualification of tenants — Each household must be income-certified before move-in. Gross income is compared to area median income (AMI) figures published annually by the U.S. Department of Housing and Urban Development (HUD).
4. Annual recertification — Owners must recertify tenant income annually (or biennially in states that have adopted IRS Notice 2012-18 streamlining) and submit compliance reports to the state HFA.
5. Extended use period — The compliance period runs 15 years; the extended use period adds at least 15 more years, for a 30-year minimum total restriction per 26 U.S.C. § 42(h)(6).
6. State monitoring — HFAs conduct physical inspections and file-review audits. Noncompliance is reported to the IRS on Form 8823, which can trigger credit recapture.

Set-aside elections define the minimum share of units reserved for income-restricted tenants. The two federal minimums are: 20% of units at or below 50% of AMI, or 40% of units at or below 60% of AMI. Many projects elect deeper targeting under state QAP requirements.

Rent limits are calculated as 30% of the applicable income limit divided by 12. A unit restricted at 60% AMI must have a gross rent (including tenant-paid utilities) at or below 30% of 60% of AMI for the household size assumed for the unit. HUD publishes income and rent limits annually at huduser.gov.

Common scenarios

Mixed-income properties: Many LIHTC developments contain both tax credit units and market-rate units within the same building. Only the restricted units count toward set-aside compliance. Market-rate units in the same building are not subject to LIHTC rent caps, though state financing layers may impose broader restrictions.

Layered subsidy: LIHTC frequently coexists with HUD project-based Section 8 contracts, HOME Investment Partnerships Program funds, or state housing trust fund financing. Each layer carries independent compliance requirements. A Section 8 tenant in a LIHTC unit must satisfy income qualification under both programs. Detailed guidance on intersecting subsidy structures appears in HUD's Multifamily Housing Program Regulations at 24 C.F.R. Part 880.

Income increases after move-in: The "available unit rule" under Section 42(g)(2)(D) addresses households whose income rises above 140% of the applicable limit after initial qualification. The rule requires that the next available unit of comparable or smaller size be rented to a qualifying household. Existing over-income tenants may remain; the owner is not required to evict them.

Decision boundaries

The boundary between LIHTC compliance and violation turns on specific numerical thresholds and procedural deadlines. Missing a recertification deadline, failing to report a vacancy on a formerly restricted unit, or allowing a unit to fall below habitability standards can each generate Form 8823 filings. A single IRS finding of noncompliance can trigger recapture of credits taken in prior years, with interest, under the three-year lookback rule at 26 U.S.C. § 42(j).

Tenant protections within the extended use period include a prohibition on eviction without good cause and a right of first refusal for qualified nonprofit organizations to purchase the property at the end of the compliance period. These protections are encoded in the LURA recorded against the property title, making them enforceable against future owners independent of the original developer's involvement.

LIHTC does not create a public housing tenancy. Tenants in LIHTC units hold private leases and are subject to standard state landlord-tenant law on issues not addressed by the federal compliance framework. State-level lease requirements, habitability standards, and security deposit rules apply in full.
