Fax Texas Department of Revenue — What to Send and How
Faxing Texas state taxes starts with an honest fact: Texas Comptroller of Public Accounts runs a lot of this online, and fax is usually for specific documents rather than the whole process. For Texas residents in Texas and the Southwest, Texas Comptroller of Public Accounts is the office behind the state's state taxes program. This page covers what to fax, how to find the office's current fax number, and how to send it securely.
Does Texas Comptroller of Public Accounts accept a fax?
You generally file and pay state taxes electronically, yet the department accepts fax for particular documents — a POA form, documents answering a notice, or an offer-in-compromise packet. Use the fax number printed on the letter you received. That one check keeps you from faxing into a system that may only take online filings.
Finding the official fax number
Because Texas Comptroller of Public Accounts handles a state tax matter through different offices, the right fax depends on your document. Check the form's instructions or the notice, verify the line on the official site, and keep it with your file.

What actually gets faxed to a revenue department

The fax number you need comes from the agency itself, not from an old search result. The form's instruction sheet is the most reliable source, since it names the unit that processes it. That two-minute check keeps sensitive documents out of the wrong queue.
