Residency guide
Becoming a South Dakota resident on the road.
South Dakota welcomes full-time travelers: there’s no state income tax, and the state has a process built for people who live on the road. You qualify if you live full time in an RV or camper, travel full time for work, or have a physical address in South Dakota. Here’s how DJ's Post fits in.
This is not tax or legal advice.
DJ's Post is a mail service, not a tax adviser or law firm. This guide is general information about South Dakota’s process, and it may not fit your situation. Talk to a qualified tax professional or attorney about your own situation before you act on it.
Step 1
Get your South Dakota address
Open a DJ's Post account and complete USPS Form 1583. For your license you'll need one document showing your name and PMB address: a receipt from us, or a piece of mail sent to your PMB.
Step 2
Spend a night in South Dakota
Stay at least one night at a South Dakota hotel, motel, campground or RV park within the year before you apply. Keep the receipt: it must show your name.
Step 3
Sign your affidavit and visit
Fill out the state's Residency Affidavit, but don't sign it yet: you can sign it in front of the driver license examiner when you visit, or in front of a notary beforehand. Bring it with your identity documents, your PMB document, your stay receipt and the application. Expect a vision test, and you'll turn in your old state's license. Driving a big rig? The Sioux Falls station has no parking for RVs or long trailers.
Step 4
Keep it current
Renewals also need a new affidavit (signed in front of an examiner, or a notary if you renew by mail or online) and a South Dakota stay receipt from the past year. You can often renew online or by mail every other time; the state's page explains when you can. With your license you can title and register vehicles through the county treasurer and update your insurance and benefits.
Voting with a PMB address
Since January 1, 2026, South Dakota registers a voter who gives only a mail service or post office box address, with no description of where they live, as a federal voter: their ballot lists only president, U.S. Senate and U.S. House. Ask your county auditor what you need to vote in state and local elections. See House Bill 1208 (opens in a new tab).
Check the current rules before you go
Requirements change, and the state has the final word. Read the South Dakota Department of Public Safety’s page for full-time travelers (opens in a new tab) for the forms, what to bring and how renewals work, or call them at (605) 773-6883. Banks and other businesses set their own address rules; some want a residential address, which a home base gives you. Curious what the move could save? Try the tax savings calculator.
