What Taxes Does OTR Handle?
MyTax.DC.gov supports a broad range of District tax accounts. The exact options shown to you depend on the tax type and whether you are paying, filing, registering or reviewing an existing account.
The available portal functions can vary by tax program. Follow the instructions for the specific return, notice or account you are handling.
What Happens if DC Real Property Tax Is Paid Late?
For real property, OTR states that a late payment can trigger a penalty equal to 10% of the tax and interest of 1.5% per month. Because the balance can increase after a deadline, check the current amount shown by OTR before making a late payment.
Common DC Tax Payment Problems
Check the spelling of the address and, for real property, try the Square and Lot identifiers. Confirm that you are using the official MyTax.DC.gov real-property search.
If the assessment itself is correct but the amount billed appears incorrect, OTR directs taxpayers to contact customer service and ask for the real-property billing section.
Call the e-services unit at 202-759-1946 for portal assistance. For account-specific questions, log in when possible and use the secure message function.
Do not assume no tax is due. Check the current property account through OTR and confirm whether a bill was delayed or whether the mailing information needs attention.
Keep the portal reference or confirmation number. Use it when contacting OTR if the payment does not appear on the account as expected.
Use the contact information printed on the official notice or contact OTR’s Collection and Enforcement Administration before sending additional payments.
What to Have Before Contacting the DC Tax Office
The information you need depends on the tax type, but having the account details from your notice or bill can make the call or office visit more efficient.
