Can anyone help- I am a Maryland Corp, licensed in DC as contracting firm. I was recently notified that I had not filed a DC Tax return. Strange since I pay MD State.

I have downloaded the form and instructions. and in lookd like I will be taxed in two different states on the same income. I have already filed 2024 and 2023 Taxes with state of MD where my company is located.

Even though your business is located in Maryland, if you're doing any sort of business within the District of Columbia, you are required to file a return in D.C. per this resource.

You may need to amend your Maryland return to apportion your income per the instructions on page 12 here. You would only need to report the income earned in Maryland on your Maryland return, and any income earned in D.C. would be reported on the return for D.C. See this link from the District of Columbia for more details on their filing requirements.
