Real Property Tax Bill Due Dates and Delayed Tax Bills

Real Property Tax Bills

District of Columbia law provides that all taxable real property in the District is subject to an annual levy of tax. A property owner will receive a property tax bill twice a year. The tax should be paid timely to avoid penalties and interest.

Real Property Tax Bill Payment Due Dates

Real Property tax bill payments are due twice a year, as follows:

  • 1st Half (October 1 – March 31) -- Payment due by March 31
  • 2nd Half (April 1 – September 30) -- Payment due by September 15

** While most real property tax bills are mailed at the same time, a range of issues can delay the mailing of some of these bills. The due date for these delayed real property tax bills is adjusted accordingly.
