Beginning on January 24, 2022, the D.C. Office of Tax and Revenue exempts at-home COVID-19 tests from the District’s sales and use tax. This means that all retail businesses selling the at-home COVID-19 tests are responsible for no longer collecting sales tax on these items. Additional information can be found by contacting the Office of Tax and Revenue’s Customer Service Center at (202) 727-4829. (D.C. Office of Tax and Revenue, DC Code 47-2005(14), effective January 24, 2022)
