Housing Credit Program FAQs

Published on March 23, 2026

The Low-Income Housing Tax Credit (Housing Credit) is a federal tax credit created by the Tax Reform Act of 1986 and designed to encourage private-sector investment in the new construction, acquisition, and rehabilitation of rental housing affordable to low-income households. Since its creation, the Housing Credit has become the most successful affordable rental housing production program in history.

The Housing Credit offers a dollar-for-dollar reduction in a taxpayerโ€™s income tax liability in return for making a long-term investment in affordable rental housing. State agencies award Housing Credits to developers, who engage private investors in the propertyโ€™s ownership partnership. The investors provide upfront equity capital to fund the construction and rehabilitation of affordable housing, allowing developers to borrow less money and pass through the savings in lower rents for lowโ€income tenants. Investors, in turn, receive a 10โ€year stream of tax credits based on the cost of constructing or rehabilitating apartments that must be rented to low-income households.

The program allows state Housing Credit agencies to allocate Housing Credits to developments they select pursuant to qualified allocation plans (QAPs) they develop that identify the type, location, and other characteristics of affordable housing needed throughout their states. The QAPs must describe the criteria agencies will apply in allocating the Credit and are subject to regular review through a public hearing and comment process. In this way, the Housing Credit empowers states to respond to the housing needs, priorities, and challenges they consider most important and to respond to changing housing priorities or challenges.
