South Dakota vs Other Zero-Tax States

State	Income Tax	Minimum Stay Required	Property Ownership Required?	Best For
South Dakota	0%	1 night	No	Digital nomads, RVers, full-time travelers
Florida	0%	183+ days recommended	No, but helpful	Expats, remote workers with ties to FL
Texas	0%	183+ days recommended	No, but helpful	Business owners, tech workers, oil industry
Nevada	0%	183+ days recommended	No, but helpful	California expats, poker players
Tennessee	0%	183+ days recommended	No, but helpful	Music industry, retirees from neighboring states

Bottom line: South Dakota is the easiest zero-tax state to establish domicile in—especially if you're always traveling and can't spend 183+ days in one state.

The 1-Night Requirement: How It Works

South Dakota law requires you to be physically present in the state for at least one night before establishing residency. This is interpreted liberally:

• Spend one night in a hotel, campground, or friend's place
• The next day, apply for your driver's license and register your vehicle
• You've now established South Dakota domicile

No 6-month wait. No 183-day test. Just 1 night.

Why Is South Dakota So Easy?

South Dakota intentionally makes residency easy to attract:

• RVers and full-time travelers: Thousands of Americans live in RVs year-round and need a legal domicile
• Digital nomads: Remote workers who travel constantly
• Wealthy individuals: Seeking zero income tax and strong trust/asset protection laws

The state benefits from vehicle registration fees, sales taxes, and economic activity from these residents—even if they're rarely physically present.

Step-by-Step: Establishing South Dakota Residency

Phase 1: Pre-Visit Preparation

1. Choose a Mail Forwarding Service

You'll need a residential address in South Dakota. Most digital nomads use a mail forwarding service:

Popular South Dakota mail forwarders:

• Dakota Post (Sioux Falls): Most popular, DMV-friendly
• My Dakota Address (Box Elder): Near Rapid City
• Americas Mailbox (Box Elder): Largest, RV-focused

Services provided:

• Residential street address (not a P.O. Box)
• Mail forwarding (scan and email, or ship to you)
• Package receiving
• Physical mailbox you can access when visiting

Cost: ~$10-$20/month for basic service

Alternative: Your Tax Base also offers Florida residency services if you prefer Florida over South Dakota. Florida has warmer weather and better infrastructure but requires 183+ days for strong domicile evidence.

2. Gather Required Documents

Before visiting South Dakota, prepare:

• Proof of identity: Passport or birth certificate + current driver's license
• Social Security card (or documentation if lost)
• Proof of South Dakota residency: Letter from mail forwarding service confirming your address
• Vehicle title and registration (if registering a vehicle)
• Proof of vehicle insurance (South Dakota minimum: 25/50/25)

Phase 2: The Visit (24-48 Hours in South Dakota)

3. Spend At Least One Night in South Dakota

Where to stay:

• Sioux Falls: Largest city, most DMV services, hotels/motels available
• Rapid City: Near Black Hills, more scenic, popular with RVers
• Campgrounds: If you're in an RV, many use campgrounds near Box Elder or Sioux Falls

Keep your receipt: Hotel/campground receipt proves you spent the night.

4. Get Your South Dakota Driver's License

Visit a South Dakota DMV (called "Motor Vehicle" offices) the day after your overnight stay. For office locations, see the SD DMV office locator.

Process:

1. Fill out Application for Driver License (Form DL-00)
2. Present documents: Passport, Social Security card, proof of SD address (mail forwarding letter)
3. Surrender your old driver's license (from your previous state)
4. Pass vision test (no written or road test if you have a valid U.S. license)
5. Pay fee: ~$28 for 5-year license
6. Get your photo taken
7. Receive temporary paper license (permanent license mailed to your SD address within 2 weeks)

No residency waiting period: You can get your license the day after spending one night.

5. Register Your Vehicle(s)

If you have a vehicle, register it in South Dakota at the same DMV visit:

Required documents:

• Vehicle title (must be in your name; if financed, bring lien information)
• Proof of South Dakota insurance
• Proof of SD residency (driver's license or mail forwarding letter)
• Odometer disclosure (if vehicle is less than 10 years old)

Fees:

• Title fee: $10
• Registration fee: Varies by vehicle type/weight (~$50-$150/year for cars)
• License plate fee: $5

No vehicle inspection required: South Dakota doesn't require emissions or safety inspections.

6. Register to Vote (Optional but Recommended)

Registering to vote strengthens your domicile claim:

• Register at DMV when getting your driver's license (they'll ask)
• Or register online at sdsos.gov

Phase 3: Post-Visit (Maintaining South Dakota Residency)

7. Update All Your Accounts and Documents

Change your address to your South Dakota residential address:

• IRS: File Form 8822 (Change of Address) or update on your next tax return
• Banks and credit cards: Update to SD address
• Brokerage/investment accounts
• Insurance policies (auto, health, life)
• Employer/clients: Update W-9 or W-4 with new address
• Social Security Administration
• Passport: Update address (optional, but recommended)
• Professional licenses

8. Close Ties to Your Old State

To avoid your old state claiming you're still a resident:

• Cancel old driver's license: Surrendered when you get SD license
• Cancel old vehicle registration
• Cancel old voter registration: Register in SD instead
• Sell property: If you owned a home, sell or rent it out
• Close bank accounts: In old state (or at minimum, change address)
• Cancel gym/club memberships in old state

9. File Your Final State Tax Return (If Applicable)

In the year you establish South Dakota residency:

• File a part-year resident return in your old state (for income earned before the move)
• No South Dakota return: South Dakota has no state income tax

Maintaining South Dakota Domicile While Traveling

Do I Need to Return to South Dakota?

No minimum stay required after establishment. Once you've established South Dakota residency, you can travel 365 days/year without ever returning.

However, for strong domicile evidence, consider:

• Returning once every 1-2 years (renew license, visit, etc.)
• Voting in SD elections (absentee ballot)
• Maintaining bank account in SD
• Keeping receipts/records of your SD connections

What If I Spend 183+ Days in Another State?

If you spend more than 183 days in a different state (especially one with income tax), that state may claim you're a resident and try to tax your income.

Strategy:

• Keep a daily log of where you spend each night
• Don't spend 183+ days in any single state (if it has income tax)
• If you do, expect to file a non-resident return in that state for income earned there
• Your South Dakota domicile should protect you from being taxed as a resident elsewhere

Mail Forwarding: How It Works

Since you're traveling, you need a way to receive mail. South Dakota mail forwarders offer:

Service Options

• Mail scanning: They open your mail, scan it, and email you PDFs
• Mail forwarding: They ship your mail to you (wherever you are) weekly/monthly
• Mail storage: They hold mail until you visit or request forwarding
• Shred/discard: Junk mail destroyed

Important Considerations

• USPS Form 1583: You'll need to fill out this form (notarized) authorizing the mail forwarder to receive your mail
• Check state laws: Some states (like California) may still claim you're a resident if you have other strong ties

See our U.S. Expat Mail Forwarding guide for more on mail services for digital nomads.

Taxes: What You Need to Know

Federal Taxes

No change: You still file a federal tax return (Form 1040) regardless of which state you live in.

If working abroad: You may qualify for the Foreign Earned Income Exclusion (FEIE) or Foreign Tax Credit (FTC).

South Dakota State Taxes

No state income tax return: South Dakota has no income tax, so you don't file a state return.

Other State Taxes

If you earn income in another state (e.g., work remotely from California for 90 days), that state may tax the income earned during those 90 days:

• File a non-resident return in the state where you worked
• Report only income earned while physically present in that state
• Since South Dakota has no income tax, you don't get a credit in SD (nothing to credit against)

See our Remote Work Tax Guide for multi-state tax scenarios.

Sales Tax

South Dakota has a 4.5% state sales tax (+ up to 2% local), which you pay when purchasing goods/services in SD.

Vehicle Registration and Insurance

Registering Vehicles Remotely

After your initial visit, you can renew registration by mail:

• SD DMV mails renewal notices to your mail forwarding address
• Pay online or by mail
• New registration mailed to your SD address (mail forwarder forwards to you)

Insurance Requirements

South Dakota requires minimum liability insurance:

• Bodily injury: $25,000 per person / $50,000 per accident
• Property damage: $25,000

Getting SD insurance: Most major insurers (GEICO, Progressive, State Farm) offer South Dakota policies. You can get quotes online without being physically in SD.

Driver's License Renewal

South Dakota driver's licenses are valid for 5 years.

Renewing by Mail

You can renew by mail or online if:

• Your license isn't expired more than 1 year
• You're a U.S. citizen

Process:

1. SD DMV mails renewal notice to your address
2. Complete renewal form
3. Pay fee (~$28)
4. New license mailed to your SD address

If you can't renew by mail: You'll need to visit a SD DMV in person (good excuse for a Black Hills trip!).

Frequently Asked Questions (FAQ)

Is the 1-night requirement really enough?

Yes. South Dakota law requires one night of physical presence. Thousands of RVers and digital nomads establish SD residency this way every year without issue.

What if my old state audits me and claims I'm still a resident?

Present evidence of South Dakota domicile:

• SD driver's license (date issued)
• SD vehicle registration
• SD voter registration
• Hotel receipt from your SD visit
• Updated bank accounts, insurance policies with SD address
• Proof you closed ties to old state

If you've properly established SD domicile and severed old state ties, you should prevail. High-tax states (CA, NY) may still challenge, so keep thorough records.

Can I use a P.O. Box as my address?

No. The DMV requires a residential street address. Use a mail forwarding service that provides a physical address (not a P.O. Box).

Do I need to own property in South Dakota?

No. You can use a mail forwarding service address. You do NOT need to own or rent property.

What if I spend 200 days in California while traveling?

California may claim you're a statutory resident if you spend 183+ days there and have a residence available to you. To avoid this:

• Stay in hotels/Airbnbs (not a home you own or rent long-term)
• Keep visits under 183 days/year
• Maintain strong SD ties

See our California Exit Guide.

Can I establish SD residency while living abroad?

You must be physically present in South Dakota for one night to establish residency. You can't do it remotely. However, after establishing SD residency, you can travel/live abroad indefinitely.

Is South Dakota better than Florida for expats?

Depends:

• South Dakota: Easier to establish (1 night), better for full-time travelers who can't spend 183+ days anywhere
• Florida: Warmer weather, better infrastructure, larger cities, more services. Requires 183+ days for strong domicile evidence.

See our Florida Tax Base services and Best States for Tax Domicile comparison.

Will South Dakota's easy residency rules change?

Unlikely. South Dakota's economy benefits significantly from attracting residents (vehicle registrations, sales tax, trust business). The state has maintained these rules for decades and shows no signs of changing them.
