FAQs

Does South Dakota tax Social Security?

Does South Dakota tax retirement income?

South Dakota doesn’t tax retirement income. This means all retirement income, including pension payments, Social Security benefits, and withdrawals from 401(k) plans and IRAs, is free from state taxes.

Do you need to file a tax return in South Dakota?

You don’t need to file a personal South Dakota state income tax return, since the state does not have an income tax. However, many residents will still need to file a federal tax return if their income meets the IRS tax filing threshold (and may be able to claim a federal refund).

However, if you purchased items from unlicensed vendors, you may need to file and pay use tax. For example, say you made an online purchase from an out-of-state retailer that is not licensed to collect South Dakota state and local taxes. In this situation, individual taxpayers are responsible for remitting the use tax. Learn more about South Dakota use tax.

Does South Dakota have a sales tax?

Yes, South Dakota has a state sales and use tax rate of 4.2%. Many municipalities also have their own local sales tax, so the combined total sales tax rate varies by location.

The bottom line

There are no personal South Dakota state refunds because South Dakota doesn’t have a state income tax. Residents don’t have to file a personal state return for this reason. However, you may need to file a federal tax return, and depending on your situation, you may owe other South Dakota taxes, such as sales and use tax or property tax.
