What Is the Low-Income Housing Tax Credit Program?
The Low-Income Housing Tax Credit (LIHTC) program is a federal initiative created in 1986 that encourages developers and investors to build and maintain affordable rental housing for people with lower incomes. Rather than providing direct money to renters, the program works by offering tax credits to individuals and companies that finance affordable housing construction and renovation projects.

Think of a tax credit as a reduction in the taxes someone owes. If a real estate developer builds a 50-unit apartment building designed for people earning modest incomes, they receive tax credits spread over 10 years. These credits make the project financially viable and allow developers to offer below-market rents. Without these credits, many developers would build market-rate housing instead, which generates higher profits.
The program operates through state housing finance agencies in all 50 states. Each state receives a pool of credits annually to distribute to qualifying projects. Since 1986, the LIHTC program has produced more than 3 million affordable rental homes across the United States, according to the National Housing Law Project. This makes it one of the largest federal programs supporting affordable housing development.
The housing created through LIHTC serves households earning between 30% and 60% of the area median income (AMI), depending on the specific project. In practical terms, this means the program serves teachers, nurses, grocery store workers, and other working families who struggle to find affordable places to live in their communities.
Practical Takeaway: Understanding how LIHTC works helps renters recognize that properties displaying "LIHTC" or "affordable housing" signage operate under specific federal rules designed to keep rents lower than market rates for a set period, typically 15 to 30 years.
How the Tax Credit Process Works for Developers and Investors
The LIHTC program follows a specific process that begins with state housing agencies announcing a funding cycle. Developers interested in building or rehabilitating affordable housing submit detailed project proposals to their state's housing finance agency. These proposals include information about the property location, number of units, construction timeline, tenant populations served, and financial projections.

State housing agencies review proposals and award credits through a competitive selection process. The agency considers factors such as whether the project serves extremely low-income residents, if it is located in an area with housing shortages, whether it includes supportive services, and if the developer has a strong track record. This competitive process ensures that limited tax credits go to the most impactful projects.
Once a developer receives credits, they must work with investors or investment groups willing to invest in the project. Here's why: tax credits are valuable because investors can use them to reduce their tax burden. An investor might put money into a limited partnership that develops affordable housing, claim the tax credits in return, and reduce what they owe to the IRS. This arrangement gives developers the upfront capital needed for construction or renovation without borrowing the entire amount from banks.
The process involves several key steps:
- Project design and financial planning
- Submission of application to state housing agency
- Competitive review and award notification
- Finding qualified investors or investment firms
- Construction or rehabilitation of the property
- Occupancy and rent-up of the building
- Compliance monitoring over 15 years (minimum)
Compliance monitoring is critical to the program's structure. Once the building opens, the state housing agency or a compliance monitor ensures that rents stay affordable, that tenants meet income requirements, and that the property maintains quality standards. This oversight continues for at least 15 years, though many projects maintain affordability longer through deed restrictions.
Practical Takeaway: If you are searching for an apartment and discover the building received LIHTC funding, the property must meet specific affordability and quality standards, and those standards are monitored by a state agency to protect your rights as a tenant.
Income Requirements and Rent Restrictions in LIHTC Properties
To live in a Low-Income Housing Tax Credit property, a household's income must fall within limits set by the program. Most LIHTC properties serve people earning up to 60% of the area median income. Some properties target lower-income households earning 30% to 50% of AMI. A small percentage of units in each building may serve households earning up to 80% of AMI.

Area median income varies significantly by location. According to the U.S. Department of Housing and Urban Development, the median income for a family of four in San Francisco is approximately $138,850, while in rural Mississippi it is approximately $64,250. Because LIHTC income limits are based on these regional figures, a household that qualifies for an affordable apartment in one state might exceed income limits in a higher-cost area.
Here are examples of how income limits work in different locations:
- In Denver, Colorado, a single person with 60% AMI income might have a limit around $47,500 annually
- In rural North Carolina, the same percentage might equal approximately $35,000
- In New York City, 60% AMI for a family of four could be $87,600
- In a small Kansas town, the equivalent figure might be $54,000
Rent restrictions are equally important. LIHTC regulations require that rent (including utilities) cannot exceed 30% of the income limit for the property. If a property is designated for households at 60% AMI, the rent must be affordable to someone earning that income level and spending no more than 30% on housing. This calculation ensures that people living in LIHTC housing maintain money for other necessities like food, transportation, and childcare.
Property owners must verify tenant income when people first move in and periodically thereafter. Tenants provide documentation such as pay stubs, tax returns, or benefit statements. If a household's income rises significantly, they may face a rent increase or could eventually move above the income limit, though many properties allow existing tenants to remain even if income increases.
Practical Takeaway: Before pursuing an apartment in an LIHTC property, gather recent income documentation and confirm with the property that your household income falls within their specific limits. Income limits change annually, so current-year figures should be verified with the state housing finance agency.
Finding and Understanding LIHTC Properties in Your Community
Locating Low-Income Housing Tax Credit properties requires knowing where to look. Most properties do not advertise as "LIHTC housing," so many renters never realize they are living in tax credit-financed apartments. Property managers, local housing authorities, and state housing agencies maintain lists of properties receiving LIHTC funding in their areas.

Several resources can help you find these properties:
- Your state's housing finance agency website, which often maintains a directory of LIHTC properties
- Local public housing authorities, which may list affordable housing options in your county or city
- HUD's Affordable Housing Search tool at hud.gov, which includes some LIHTC properties
- Nonprofit housing organizations in your area, which frequently work with LIHTC developers
- Community action agencies, which offer housing search information
- Local 211 services, which provide information about community resources including housing
When you find a potential property, ask the property manager directly whether it is an LIHTC project. If it is, request information about current income limits, rent amounts, lease terms, and required documentation. Reputable LIHTC properties maintain clear information about their affordability restrictions and welcome tenant inquiries.
Understanding what LIHTC status means for your tenancy is important. LIHTC properties must maintain affordable rents and serve lower-income households, but they operate as regular rental properties in most other respects. You sign a lease, pay rent on time, and follow standard lease agreements. The main difference is that rent levels are controlled, property management is monitored for compliance, and income verification occurs during the application process.
Be cautious of misleading claims. Some properties advertise as "affordable" without being LIHTC-funded or may claim affordability status they do not actually
