DC’s Office of Tax and Revenue (OTR) uses the income analysis approach (among others) to determine the assessed value of commercial and multi-family real estate. It is important to remember the April 15 deadline for the filing of the appropriate income and expense form. The filing can be done on-line at http://otr/cfo.dc.gov. Select the Forms tab, then Real Property Tax Forms and Publications, then select the I&E report tab and select the form to complete. Alternatively, you can file a paper copy by mailing it certified mail to:

Real Property Assessment Division
Income and Expense Reporting
P.O. Box 71440
Washington, DC 20024

Or delivering by hand to:

OTR Customer Service Center
1101 4th St SW
Suite W270
Washington, DC 20024.

Be sure to note the Square/Suffix/Lot number. Failure to file by April 15 can result in a penalty in the amount of 10% of the tax bill. For information, contact Anthony Daniels at (202) 442-6794 or at anthony.daniels@dc.gov.
