What We Do

The Department of Tax Administration's (DTA) Real Estate Division is tasked with collecting data for all real property in Fairfax County. DTA uses that data to annually assess real property in a fair and uniform manner at estimated fair market value as of January 1 of each year. The tax rate, set by the Board of Supervisors, is applied to that value to determine the tax amount due. Real estate taxes are paid annually in two installments due July 28 and December 5.
