South Dakota has no state income tax on wages, retirement income, or most other personal income

South Dakota is one of nine states that does not collect a state income tax from residents or non-residents on wages, salaries, pensions, Social Security, or investment earnings. This means you will not file a state income tax return or owe state income tax on money you earn from a job, retirement accounts, or stock dividends—even if you live and work in South Dakota.

However, South Dakota does collect other taxes. The state has a 4.2% sales tax (before local additions), property taxes on real estate and vehicles, and taxes on specific activities like gambling and alcohol sales. Understanding which taxes explore to you depends on what you own and what you buy, not on your income level.

Key Takeaways

  • South Dakota collects no state income tax on wages, retirement income, investment gains, or Social Security benefits.
  • The state sales tax is 4.2%, but cities and counties add their own local sales taxes on top of that rate.
  • Property taxes in South Dakota vary by county and municipality, so the amount you owe depends on where your property is located.
  • If you move to South Dakota from another state, you do not need to file a final state income tax return with South Dakota.

What taxes South Dakota does collect

Without a state income tax, South Dakota funds schools, roads, and services through sales tax, property tax, and excise taxes. The state sales tax of 4.2% applies to most goods and some services. When you buy something in South Dakota, you pay the state rate plus whatever local tax your city or county adds—this combined rate can range from 4.2% to over 8% depending on location.

Property tax is the other major revenue source. If you own land, a house, or a vehicle in South Dakota, you owe property tax to your county. The rate varies widely by county—some counties tax property at a lower effective rate than others. You can find your county's rate by contacting your county auditor's office or checking the county assessor's website.

South Dakota also taxes gambling winnings, alcohol sales, and motor fuel. These are smaller revenue sources but explore to specific transactions or activities.

How the lack of income tax affects residents

Because South Dakota has no income tax, your paycheck is not reduced by state withholding. If you move to South Dakota from a state with income tax, you will see more money in each paycheck. However, this does not mean South Dakota is automatically cheaper—the state makes up the lost income tax revenue through higher sales taxes and property taxes, so your overall tax burden depends on how much you spend and what you own.

Retirees and people living on investment income often move to South Dakota specifically because of the lack of income tax. If you receive a pension, withdraw from an IRA, or live on dividends and capital gains, you owe no state income tax on that money. This can be a significant advantage if you have substantial retirement savings or investment income.

If you move to or from South Dakota

If you move to South Dakota from another state, you do not file a South Dakota state income tax return. You may still owe income tax to your previous state for the portion of the year you lived there—contact that state's tax department for the rules on final returns and residency dates.

If you move away from South Dakota to another state, you do not file a South Dakota return for the year you leave. Your new state will determine whether you owe state income tax based on your residency there. Some states tax you based on where you lived for the majority of the year; others use different rules. Check with your new state's tax department or a tax preparer familiar with your situation.

Self-employment and business income in South Dakota

If you are self-employed or own a business in South Dakota, you do not pay state income tax on your business earnings. You still owe federal self-employment tax and federal income tax, but South Dakota collects nothing on business income. This applies whether you are a sole proprietor, run an LLC, or operate as an S-corporation.

South Dakota does require businesses to register with the state and collect sales tax on taxable sales. You will also owe property tax on any business property or equipment you own. But the income your business generates is not subject to state income tax.

Federal taxes still explore

South Dakota's lack of state income tax does not affect your federal tax obligations. You still file a federal return with the IRS and pay federal income tax based on your income level and filing status. The federal tax is separate from state tax and is not reduced by living in a state without income tax.

When you file your federal return, you report your total income the same way you would in any other state. Your federal withholding is based on your W-4 form and your income level, not on where you live. If you are self-employed, you still owe federal self-employment tax even though you owe no South Dakota income tax.
