South Dakota Overtime Calculator 2026

How overtime pay is taxed in South Dakota for 2026

Under the federal Fair Labor Standards Act (FLSA), non-exempt employees must be paid at least 1.5× their regular rate for every hour worked beyond 40 in a workweek. This calculator takes your base hourly rate and overtime hours, computes the time-and-a-half gross, and then applies 2026 federal income tax, Social Security, Medicare, and your state's income tax to show what actually lands in your bank account — not just the headline gross.

A common myth is that overtime is "taxed higher." It isn't. Overtime dollars are ordinary income taxed at your normal marginal rate; the reason an overtime check can feel over-withheld is that payroll systems often annualize a single large paycheck and withhold as if you earned that much every period. The extra withholding comes back at filing. What genuinely changes for 2026 is the One Big Beautiful Bill Act's new deduction for qualified overtime: you can deduct the FLSA "half" premium portion of your overtime — up to $12,500 (single) or $25,000 (married filing jointly) per year — as an above-the-line deduction for tax years 2025 through 2028. The deduction phases out by $100 for every $1,000 of modified AGI above $150,000 ($300,000 joint), and it applies only to W-2 employees, not 1099 contractors.

Starting in tax year 2026, employers must break out the overtime premium separately on your W-2 in Box 12 using new Code TT, which is the figure that feeds the deduction. Note that some states (California, Alaska, Nevada, and others) also require daily overtime — for example, 1.5× after 8 hours in a single day in California — which federal law does not.

South Dakota is one of the states with no state income tax, so your overtime pay here is shaped only by federal income tax, Social Security, and Medicare — there is no state layer to subtract, which is why take-home in South Dakota runs higher than in most states at the same salary.
