DISTRICT OF COLUMBIA PROPERTY TAX & EQUALIZATION FAQ

STATUTORY REFERENCE
What is the statutory deadline to appeal property taxes in District of Columbia? +
The resolved statutory filing deadline for District of Columbia is April 1, 2027 (First-level appeal to OTR); August 1 to Real Property Tax Appeals Commission. Initial local reviews are filed with the Real Property Tax Appeals Commission (RPTAC), with administrative escalation to the Superior Court of the District of Columbia (Tax Division).
How is residential property assessed in District of Columbia? +
Under District of Columbia law, residential real property is assessed at 100% of fair market value (and commercial property at 100%). Equal and uniform taxation across properties is protected under D.C. Code § 47-820 ("The assessed value of all real property shall be the estimated market value of such property as of January 1").
How does Truth-in-Taxation work during District of Columbia county reappraisals? +
Under D.C. Code § 47-864 (Assessment increase limitation credit), when a county completes a reappraisal cycle (Annual tri-group rolling revaluation by OTR), the taxing authority must calculate a certified revenue-neutral tax rate so the reappraisal itself does not automatically create an unadvertised windfall tax increase.
