South Dakota does not have a state income tax

South Dakota is one of nine states with no state income tax on wages, salaries, or investment income. This means you will not owe South Dakota state income tax on money you earn, regardless of how much you make or what type of work you do. If you live and work in South Dakota, you skip the state income tax return that residents of other states file.

However, no state income tax does not mean no state taxes at all. South Dakota funds its government through other sources, primarily sales tax, property tax, and excise taxes. Understanding what you do and do not owe is important for budgeting and tax planning, especially if you moved to South Dakota from a state that does collect income tax.

Key Takeaways

  • South Dakota has no state income tax on wages, salaries, self-employment income, or investment gains.
  • You still owe federal income tax to the IRS, and South Dakota still collects sales tax and property tax.
  • If you moved to South Dakota from another state, you may no longer need to file a state income tax return, but you should confirm your residency status with the South Dakota Department of Revenue.
  • Retirees and investors may find South Dakota's tax structure favorable because retirement income and capital gains are not taxed at the state level.
  • South Dakota's sales tax rate is 4.5 percent statewide, though cities and counties add local sales taxes that can raise the total to 8 percent or higher.

What taxes South Dakota does collect

Without an income tax, South Dakota relies on a sales tax to fund state services. The statewide sales tax rate is 4.5 percent on most goods and services. Many cities and counties layer on additional local sales taxes, so the total rate you pay at checkout can range from 4.5 percent to over 8 percent depending on where you shop. Groceries are taxed at a lower rate of 2 percent in South Dakota.

South Dakota also collects property tax, which is assessed by county and varies widely by location. Property tax funds schools, local government, and other services. The state does not set a uniform rate; each county and municipality sets its own. If you own a home or land in South Dakota, you will receive a property tax bill from your county assessor.

The state also charges excise taxes on specific items like gasoline, cigarettes, and alcohol. These are smaller taxes added to the purchase price and are often invisible at the register, but they contribute to state revenue.

Federal income tax still applies to you

Living in South Dakota does not exempt you from federal income tax. You still owe the IRS on all income you earn, and you must file a federal tax return each year if your income exceeds the threshold set by the IRS. For 2024, that threshold is $14,600 for a single filer under age 65, though it varies by filing status and age.

Many people confuse state and federal taxes. The IRS collects federal income tax from every state, including those with no state income tax. South Dakota straightforward does not add its own layer on top of what you owe the federal government.

How to confirm your residency status for tax purposes

If you recently moved to South Dakota from another state, you should confirm your residency status with the South Dakota Department of Revenue. Residency determines which state can tax your income. Generally, you are a South Dakota resident for tax purposes if you live in the state for more than half the year or if you have a permanent home there.

If you moved mid-year, you may owe income tax to your previous state for the months you lived there. Contact that state's revenue department to find out whether you need to file a part-year return. Some states have reciprocal agreements that simplify this process, while others require you to file separately.

The South Dakota Department of Revenue can be reached through its website, and staff can answer questions about residency and whether you need to file any state returns. Having clear documentation of your move date — such as a lease, utility bill, or driver's license — helps establish when you became a South Dakota resident.

Retirement income and investment gains in South Dakota

One advantage of South Dakota's tax structure is that retirement income is not taxed at the state level. If you receive Social Security, pension payments, or distributions from a 401(k) or IRA, South Dakota does not tax those funds. You still owe federal tax on most retirement income, but the state does not take a cut.

Similarly, capital gains — profits from selling stocks, real estate, or other investments — are not taxed by South Dakota. You owe federal capital gains tax, but not a state tax. This structure can make South Dakota attractive to retirees and investors, though you should consider the higher sales and property taxes when evaluating the overall tax burden.

Moving to South Dakota for tax reasons

Some people move to South Dakota specifically because of the lack of state income tax. If you are considering a move for tax reasons, remember that the absence of income tax is only one piece of your total tax picture. Sales tax and property tax rates vary by county and can be substantial, especially if you own property or spend heavily on taxable goods.

Additionally, you must actually live in South Dakota to benefit from its tax structure. You cannot straightforward claim residency to avoid taxes in your home state. The IRS and state revenue departments scrutinize residency claims, and falsely claiming residency can result in penalties and back taxes. If you move to South Dakota, you should establish genuine residency by obtaining a driver's license, registering to vote, and maintaining a home there.
