Federal income tax withholding (2026)
Federal income tax withholding is calculated using the annualization method from IRS Publication 15-T. Your per-period gross pay is annualized, reduced by the standard deduction ($15,000 single / $30,000 married / $22,500 head of household in 2026), and then taxed at the applicable bracket rates. The resulting annual tax is divided by your number of pay periods.
2026 federal tax brackets
| Taxable Income (Single) | Rate |
|---|---|
| $0 – $11,925 | 10% |
| $11,926 – $48,475 | 12% |
| $48,476 – $103,350 | 22% |
| $103,351 – $197,300 | 24% |
| $197,301 – $250,525 | 32% |
| $250,526 – $626,350 | 35% |
| Over $626,350 | 37% |
FICA: Social Security & Medicare
FICA taxes are the same in every state. Social Security is withheld at 6.2% on wages up to $176,100 (2026 wage base). Once your wages reach that cap in a calendar year, Social Security withholding stops. Medicare is withheld at 1.45% with no wage cap. An additional 0.9% applies to wages above $200,000 (single) or $250,000 (married).
South Dakota vs. high-tax states
A worker earning $75,000 per year in South Dakota saves roughly $3,750–$7,500 annually compared to living in a state with a 5%–10% income tax. For a $100,000 earner, that's $5,000–$10,000 per year — a meaningful difference in take-home pay and long-term wealth accumulation.
Pre-tax deductions and your paycheck
Traditional 401(k) contributions and employer-sponsored health insurance premiums (Section 125/cafeteria plan) reduce your federal and state taxable income, lowering your income tax withholding. However, 401(k) contributions do not reduce FICA (Social Security and Medicare) wages. Health insurance premiums under a Section 125 plan do reduce FICA wages. Use the "Show deductions" section above to model your specific situation.
Frequently asked questions
- South Dakota has no state income tax, so residents pay $0 in state income tax on their wages. You still owe federal income tax and FICA (Social Security + Medicare), which together typically take 20–30% of each paycheck.
- South Dakota has no state income tax, and there is no statewide local income tax system. Your only payroll deductions are federal: income tax, Social Security, and Medicare.
- Start with your gross pay per paycheck. Subtract: (1) federal income tax based on your filing status and 2026 brackets; (2) Social Security at 6.2% up to the $176,100 wage base; (3) Medicare at 1.45%; (4) no state income tax applies in South Dakota. Any pre-tax deductions like 401(k) or health insurance reduce your taxable income further. The calculator above does this math instantly.
