Low-Income Housing Tax Credit (LIHTC)

What Is the Low-Income Housing Tax Credit (LIHTC)?

The Low-Income Housing Tax Credit, or LIHTC, is a federal tax incentive used to finance the construction and rehabilitation of income-restricted rental housing. Instead of directly operating housing, the program uses tax credits to attract private capital into affordable rental development.

LIHTC is one of the main production tools for affordable rental housing in the United States. It sits on the supply side of housing policy, which makes it different from tenant-based assistance such as vouchers or short-term emergency rent aid.

Key Takeaways

• LIHTC is a federal tax-credit program that supports affordable rental housing development.
• It is aimed at producing or preserving income-restricted rental units.
• The program uses private capital rather than direct federal ownership of the housing.
• LIHTC is a supply-side housing tool, not a tenant voucher.
• It is one of the most important financing structures for affordable rental housing in the U.S.

How LIHTC Works

States allocate housing tax credits to qualifying affordable-housing projects, and developers use those credits to attract investors. In exchange, the projects must meet income-restriction and rent-restriction requirements for a defined period. The result is a financing structure that lowers the cost of creating or preserving affordable rental units.

That mechanism is why LIHTC often appears in discussions of housing supply rather than direct rent relief. The goal is to expand the stock of below-market or income-restricted housing, not to directly subsidize an individual tenant's current rent bill.

How LIHTC Supports Affordable Housing Supply

LIHTC supports affordable housing supply because housing affordability problems are often rooted in limited supply as well as weak household purchasing power. A program that helps finance more affordable units can affect the market in a different way from vouchers, public housing, or rent regulations.

A large share of affordable-housing development also depends on complex capital stacks, and LIHTC is often one of the central financing layers in those deals.

The Bottom Line

The Low-Income Housing Tax Credit is a federal tax incentive used to finance affordable rental housing development. It is one of the country's main tools for producing and preserving income-restricted housing.
