Legislation signed into law on December 27, 2020, fixed the rate for the 30% present value low-income housing tax credit (LIHTC), which had dropped to a historic low of 3.07 in 2020, at 4% (the 4% Floor). Congress hopes that the 4% Floor will increase the supply of affordable rental housing in 2021 and beyond by reducing the need for other types of financing and subsidies for qualified LIHTC projects.
