Total tax burden in South Dakota

Income tax alone is misleading. South Dakota's combined burden (income + sales + property) on a typical household earning $100,000 with a $350,000 home.

Assumes 40% of income goes to taxable purchases. Actual sales tax exposure varies with spending mix (groceries often exempt). Property tax assumes home ownership; renters effectively pay through rent.

vs neighboring states — total burden on $100k

Single-bracket income tax comparisons miss the bigger picture. TX has no income tax but property tax 2-3× higher than CA. This is the apples-to-apples comparison.

Common questions

What is the South Dakota income tax rate for 2025?
South Dakota's top rate is 0.00%. The federal top marginal rate is 37%, applied above the highest bracket. Most filers pay an effective rate well below the top — the brackets only apply to the slice of income inside each band.
When did the 2025 brackets take effect?
Federal brackets are published by the IRS each November in a Revenue Procedure (Rev. Proc.) for the following tax year. They take effect January 1 and apply to income earned that year, filed by April of the following year. State brackets are set by state legislatures and may align with or diverge from the federal calendar.
Are these brackets adjusted for inflation?
Federal: yes — IRS indexes brackets to chained CPI under the TCJA (since 2018). State: varies. Some states (CA, MN, OR, others) index their brackets annually; many do not, which creates "bracket creep" over time as nominal wages grow.
