Fax Maryland Department of Revenue — What to Send and How
If you need to fax a document for a state tax matter in Maryland, the first thing to know is that Comptroller of Maryland may handle much of this online — so confirm fax is accepted and for which documents. Comptroller of Maryland administers Maryland's state taxes program and takes in documents for residents throughout the Mid-Atlantic. This page covers what to fax, how to find the office's current fax number, and how to send it securely.
Does Comptroller of Maryland accept a fax?
State tax filing and payment happen online for most people, but the revenue department still takes fax for specific things: a power-of-attorney authorization, a response to an audit or notice letter, installment-agreement paperwork, and certain forms the department names. That one check keeps you from faxing into a system that may only take online filings.
Finding the official fax number
The reliable way to reach Comptroller of Maryland by fax is to use the number the receiving office publishes today — on the form instructions or the request you got — and confirm it by phone, since department lines change.
