How Your South Dakota Paycheck Is Calculated

Every paycheck goes through the same basic pipeline from gross pay to the net amount that hits your bank account:

Gross Pay — Your total earnings for the pay period. For hourly workers this is (hours × rate) plus any overtime or double-time premiums. For salaried employees it’s your annual salary divided by the number of pay periods.
Pre-Tax Deductions — Contributions to 401(k), 403(b), HSA, or FSA are subtracted before income taxes are calculated. These lower your taxable wages but Social Security and Medicare still apply to the full gross in most cases.
Federal Income Tax — Withheld using the IRS Publication 15-T percentage method based on your W-4 filing status, credits, and additional withholding elections. For 2026, rates range from 10% to 37%.
State Income Tax — South Dakota has no state income tax, so nothing is withheld for state income tax from your paycheck.
FICA Taxes — Social Security (6.2% on wages up to $184,500) and Medicare (1.45% on all wages). If your year-to-date earnings exceed the Social Security wage base, that portion stops being withheld.
Net Pay (Take-Home) — What’s left after all taxes and deductions. This is the amount deposited into your account each pay period.

Good to Know

Review your W-4 periodically. If you consistently receive a large refund, you may be over-withholding. Consider reviewing your W-4 Step 3 credits or Step 4(b) deductions to better align your withholding with your actual tax liability. The IRS Tax Withholding Estimator can help.
Benefits of contributing to a 401(k) or 403(b). Pre-tax retirement contributions can reduce your federal and state taxable income for the year. Even a modest percentage — say 3% to 6% — may noticeably lower your tax withholding while building long-term savings. Consult your plan administrator or a financial advisor for guidance.
Benefits of an HSA if you’re eligible. Health Savings Accounts offer a rare triple tax advantage — contributions lower your taxable income now, the balance grows tax-free, and withdrawals for qualified medical expenses are also tax-free. If you’re enrolled in a qualifying high-deductible health plan, an HSA is one of the most tax-efficient savings tools available.
