No State Income Tax: What It Actually Saves You in Yankton
By Michelle Maloney, Broker/Owner, Maloney Real Estate · SD License #14315
The short version
South Dakota has no state income tax. Not a low rate, not a flat rate on part of your income. Zero, on wages, salary, business income, retirement income, and investment income, per the South Dakota Department of Revenue. For buyers relocating to Yankton from Minnesota, Iowa, or Nebraska, this is the single largest annual financial difference between where they lived and where they are going. Housing gets most of the headline attention, but the income tax gap is what compounds over 10 or 20 years into a meaningful number.
What does South Dakota's zero income tax actually mean?
South Dakota levies no personal income tax at the state level per the South Dakota Department of Revenue. That applies to all earned income (wages, salary, self-employment), all retirement income (Social Security, pensions, 401(k) and IRA withdrawals), and all investment income (dividends, capital gains, interest). There is no phase-in, no partial exemption, and no threshold. If you earn it in South Dakota or receive it as a South Dakota resident, the state takes zero. The South Dakota sales tax is 4.5 percent state rate plus 2 percent city rate in Yankton, totaling 6.5 percent per the South Dakota Department of Revenue. That is where you notice the tax day to day. The income tax benefit shows up in your paycheck and at year-end.
How much does a Minnesota household save?
Minnesota's state income tax runs 5.35 percent at the lowest bracket and 9.85 percent at the top per the Minnesota Department of Revenue 2026 rates. On a $100,000 household income, a Minnesota family pays roughly $6,800 in state income tax. Moving to Yankton, that bill goes to zero. On $150,000, you save closer to $11,000 per year. On $200,000, closer to $15,000. Over 10 years at $100,000, that is $68,000. That is a paid-off car, a college contribution, or a decade of extra retirement savings just from the tax change. Minnesota also taxes Social Security benefits above certain income thresholds per the Minnesota Department of Revenue. South Dakota does not.
How much does an Iowa household save?
Iowa enacted a 3.8 percent flat income tax rate effective 2025 per the Iowa Department of Revenue. On $100,000 of income, an Iowa household pays roughly $3,800 in state tax. Move to Yankton and that goes to zero. On $150,000, the savings is $5,700. Iowa also taxes retirement income including pensions and 401(k) distributions for some income levels per the Iowa Department of Revenue rules. South Dakota taxes none of it. For retirees moving from Iowa, the combination of zero tax on retirement withdrawals and zero tax on Social Security makes the savings materially larger than the $3,800 figure for working households.
How much does a Nebraska household save?
Nebraska's top marginal income tax rate is 6.64 percent per the Nebraska Department of Revenue. On $100,000 of income, a Nebraska household pays roughly $6,640 in state income tax. South Dakota: zero. On $150,000, you save about $9,960 per year per the Nebraska rate schedule. That is $99,600 over a decade at that income level. Nebraska also taxes Social Security benefits for higher-income households. The income tax savings coming from Omaha or Lincoln are comparable to savings from Minneapolis, which surprises most Nebraska buyers who expected the gap to be smaller.
Retirement income in South Dakota versus everywhere else
This is the part retirees from any state underestimate. In South Dakota, your 401(k) withdrawals are untaxed at the state level. Your pension is untaxed. Your Social Security is untaxed. Your IRA distributions are untaxed. Per the South Dakota Department of Revenue, none of it is subject to state income tax. Compare that to Minnesota, where Social Security is partially taxed for households above certain income thresholds, and where 401(k) and pension income is taxed as ordinary income at the full 5.35 to 9.85 percent rate per the Minnesota Department of Revenue. A retired couple drawing $60,000 from a pension and Social Security saves roughly $3,200 a year just by being South Dakota residents instead of Minnesota residents. Over a 20-year retirement, that is $64,000. Add the lower housing costs in Yankton and the math runs well in your favor.
What is the property tax situation in Yankton?
Property tax in Yankton runs 1.22 percent effective per the City of Yankton. On a $241,000 home, the January 2026 Redfin median, that is about $2,940 per year. Compare that to Minnesota's statewide average effective property tax rate of 1.12 percent per the Minnesota Department of Revenue, which sounds close until you apply it to Minneapolis metro home prices of $385,000 or more (Redfin January 2026). A $385,000 Minnesota home at 1.12 percent runs $4,312 per year. A $241,000 Yankton home at 1.22 percent runs $2,940. You pay a slightly higher rate but on a significantly lower value, and you pocket the income tax difference on top.
What is the full cost of living comparison?
Yankton's cost of living index is 88.1 versus the US average of 100 per Sperling's Best Places. Housing lands at 75 on the same index. A household spending $6,100 per month in Minnesota spends roughly $5,200 per month for the same standard of living in Yankton per Realtor.com county data, about 15 percent less. Groceries are not subject to South Dakota sales tax per state law. Utilities run slightly below the national average, around a 95 index per Sperling's. When you add the income tax savings to the cost of living discount, the effective annual advantage for a $100,000 household relocating from Minnesota is not just $6,800 in tax savings but closer to $7,500 to $9,000 per year after all adjustments. Use the buyer guide to size the mortgage you can afford given your specific income and savings.
Does South Dakota tax capital gains from a home sale?
No. South Dakota levies no state capital gains tax per the South Dakota Department of Revenue. When you sell a Yankton home, you pay no state tax on the profit. Federal capital gains tax still applies if your gain exceeds the $250,000 single filer or $500,000 married filer exclusion under IRS rules. Sellers keep their net proceeds without a state cut. Minnesota taxes capital gains as ordinary income at the full graduated rate per the Minnesota Department of Revenue. Iowa taxes capital gains, though rates vary by holding period per the Iowa Department of Revenue. Nebraska taxes capital gains as ordinary income per the Nebraska Department of Revenue. Moving the sale to South Dakota eliminates the state portion entirely.
How the savings stack with Yankton housing costs
The income tax and housing advantages compound rather than just add. A Minnesota buyer earning $100,000 who buys a $241,000 Yankton home instead of a $385,000 Twin Cities home saves $6,800 per year in income tax and $1,372 per year in property tax compared to a similarly priced Minnesota home. The down payment required is $48,200 on a $241,000 home versus $77,000 on a $385,000 home at the same 20 percent down. The monthly mortgage payment on $241,000 at current 30-year rates is about $400 to $500 less than on $385,000. Every single component runs in the same direction. The Yankton financial case is not one big number. It is five moderate numbers that all point the same way, and they compound every year you stay.

What is the one financial tradeoff to know?
South Dakota sales tax at 6.5 percent in Yankton is real and shows up on large purchases. A $50,000 car purchase has a $3,250 sales tax bill. A $5,000 appliance purchase adds $325. For day-to-day grocery and household spending, South Dakota's grocery exemption from sales tax softens the impact. The sales tax rate is not a reason to avoid the move, but it is the line item that surprises buyers who have only read about the income tax advantage and assumed everything was cheaper. Talk to your CPA about your specific income and spending profile to get an accurate net annual advantage number before you close.
