Actually, you can! There was a presentation at DEFCON this year (DEFCON 26) showing exactly this:

> "See for yourself first-hand as we give a live demonstration of the first ever full fax exploitation, leading to complete control over the entire device as well as the network, using nothing but a standard telephone line. "

Maybe it's time for you to find another tax preparer. Mine accepts encrypted documents with her public key.

I need my tax guy to be an expert on tax law way more than I need them to be on the cutting edge of computer communications and security.

If he wants to stick to his old-school fax machine and keeps me on the right side of the tax agencies, I can accommodate his preferences on tech.
