Understanding Your Tax Burden

At $120,000 gross income in South Dakota, your marginal federal tax bracket is 24% — but your effective federal rate is only 15.3% because the progressive tax system taxes different portions of your income at different rates. As a no-income-tax state, South Dakota saves you significantly compared to high-tax states.

Your total effective tax rate of 22.9% means you keep $92,482 out of every $120,000 earned (77.1%). For strategies to reduce your tax burden, consider maximizing 401(k) contributions ($23,000/year for 2024), HSA contributions, and itemizing deductions if they exceed $14,600.
