About
Alexander Powell is a Washington, DC tax attorney who represents clients in IRS disputes and U.S. Tax Court cases.
The trial and appellate record.
I tried more than 75 cases to verdict as a Maryland prosecutor. I later drafted more than 100 appellate opinions as a staff attorney at the Appellate Court of Maryland. I now represent clients in IRS examinations, collections, penalty disputes, unfiled-return matters, and U.S. Tax Court cases.
I was named a 2026 Elite Lawyer in Tax Law.
For each matter, I identify the deadline, explain the available options, and prepare the response for the IRS, tax authority, or court.
