Does South Dakota Department of Revenue 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. Either way, do not assume fax works everywhere — check the agency's rules for your document first.

Finding the official fax number

The reliable way to reach South Dakota Department of Revenue 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.

Good labeling is the difference between a same-week match and a filing that sits in a queue. Label each page with the notice number so the department can match the response. Keep the transmission confirmation in case you ever need to prove the filing went through on time.

Authorizations and notice responses you fax

The state tax documents that move by fax are authorizations, notice responses, and payment-arrangement paperwork. Send the form or response together with the taxpayer name, the account or notice number, and the documents it requests. Faxing beats mail when a notice's response window is already running.
