Retiring in South Dakota: how your income is taxed
South Dakota is very tax-friendly for retirees. On a typical retirement income it ranks tied for #1 of 51 with 18 other states for the lowest state income tax.
Assumptions behind this comparison
The ranking uses a full-year resident, single filer age 67, with $30,000 Social Security, $20,000 private defined-benefit pension, $20,000 traditional IRA withdrawals under 2026 rules. It models a general private pension and traditional IRA withdrawals. Public or military pension exceptions, early-distribution penalties and itemized deductions require separate checking. Maryland and Indiana estimates include an approximate statewide-average county income tax; other local income taxes are not modeled. A state with no income tax differs from a state that exempts only specified retirement income.
The joint table uses two spouses age 67, with each income category split equally between them. Personal exclusions follow each spouse's own eligible income; some states instead allow a joint cap. The calculator initially assigns household income to you and lets you enter your spouse's actual age and share. Read the source instructions for your pension type.
The rules in South Dakota

State income tax in South Dakota: $0 a year
In South Dakota, qualifying employer-plan withdrawals can receive the pension exclusion while traditional IRA withdrawals do not. Keep each account in its own field when changing state; the calculator applies the state-specific treatment.
The employer-plan field supports federally taxable private 401(k) / 403(b) retirement distributions owned by someone aged 60 or older. Earlier distributions and Hawaii, Mississippi or Pennsylvania employer-plan scenarios are not calculated; funding or plan retirement eligibility needs a separate check. Enter each amount once; do not include completed rollovers, Roth payments or special public/military plans.
Older shared links did not identify employer-plan withdrawals separately. Pension and IRA amounts have been left unchanged. If an old amount includes 401(k) or 403(b) withdrawals, move that portion into the employer-plan field before comparing states; the tool cannot infer the original account type.
Household totals include taxable private pensions and traditional retirement withdrawals. Other ordinary income means taxable interest and ordinary dividends; capital gains, qualified dividends, tax-exempt interest, wages, Roth distributions and special public or military pension rules need a separate calculation. Disability and survivor eligibility are not assessed by this tool. Age bands represent the listed ages for the full year; midyear eligibility and birth-date exceptions need checking.
Local income taxes are not modeled here, except the approximate statewide-average county rates included when you select Maryland or Indiana.
In South Dakota you'd pay about $0 in state income tax and $4,336 in federal income tax on $70,000 of retirement income, keeping $65,664 (6.2% total).
