Montana Overtime Calculator

Overtime in Montana is withheld on at your normal federal rate: there is no separate overtime tax rate. Federal law sets overtime at 1.5× your regular hourly rate past 40 hours in a workweek, and those hours face federal income tax, FICA of 7.65%, and Montana's graduated income tax (4.7% to 5.65%) in 2026, though the federal premium is now deductible when you file.

Is overtime taxed in Montana?

Yes, but not at a special rate: overtime in Montana is withheld on in the same federal brackets as regular wages plus Montana's graduated income tax (4.7% to 5.65%). For 2025-2028 the federal premium, the "half" of time-and-a-half, is also deductible when you file, up to $12,500 ($25,000 married filing jointly). Bigger checks can have more withheld up front because withholding is calculated per paycheck, but that evens out on your tax return. Against the 4 states Montana borders, the same ten overtime hours a week is worth $14,177 here: South Dakota keeps $992 more ($15,168), Wyoming keeps $992 more ($15,168), North Dakota keeps $857 more ($15,033) and Idaho leaves $42 less ($14,135). North Dakota, South Dakota and Wyoming are the only borders worth crossing for the tax alone.

How overtime is taxed in Montana

Short answer: no: Montana does not tax overtime at a higher rate, and neither does the IRS. Overtime pay (1.5× your regular rate past 40 hours/week) is withheld on as ordinary income in the same federal and Montana brackets as the rest of your wages. Big overtime checks can have more withheld up front because withholding is calculated per paycheck, but that evens out on your tax return. Here's the full picture.

  • Overtime rate is 1.5× your regular pay: Federal law requires at least 1.5 times your regular hourly rate for hours worked beyond 40 in a workweek. Some states and employers offer higher rates.
  • Withheld as ordinary income: There is no special tax rate for overtime pay. It's added to your regular wages and withheld on through the same federal brackets plus Montana's graduated income tax (4.7% to 5.65%).
  • The premium is deductible federally (2025-2028): When you file, the extra half of time-and-a-half the FLSA requires comes off your federal taxable income: up to $12,500, or $25,000 married filing jointly, phasing out above $150,000 of income. Social Security and Medicare still apply.
  • Higher income can mean higher withholding: Because overtime increases your total paycheck, your employer annualizes the higher amount when calculating withholding, which can result in a higher rate on the overtime portion.
  • You always take home more by working overtime: Even in a high tax bracket, you keep more than 50% of each overtime dollar. Higher taxes on overtime never mean you'd be better off working fewer hours.

Frequently Asked Questions

On your paycheck, overtime in Montana is ordinary wages: there is no special overtime tax rate. It's withheld on through Montana's graduated income tax (4.7% to 5.65%) along with the rest of your wages, and because overtime raises the pay period's total, a larger percentage of each overtime dollar may be withheld. The federal overtime deduction you claim at filing doesn't change Montana's withholding, which still applies to every overtime dollar.

Not fully. For 2025-2028 the federal premium, the "half" of time-and-a-half, is also deductible when you file, up to $12,500 ($25,000 married filing jointly). It's claimed on Schedule 1-A, phases out above $150,000 of income ($300,000 joint), and doesn't reduce Social Security or Medicare. It's a federal deduction, so don't assume Montana income tax follows it. Your employer still withholds on overtime unless you claim the deduction on a new W-4, so for most people it shows up as a bigger refund.

Overtime can push your annualized income into a higher bracket, but only the dollars above the threshold are taxed at the higher rate: you always take home more by working the hours. Priced for Montana: five overtime hours a week is worth $7,376 a year after tax, ten overtime hours a week is worth $14,177 a year after tax, fifteen overtime hours a week is worth $20,485 a year after tax, against $19,500 gross on the middle figure.

Under the Fair Labor Standards Act, non-exempt employees must be paid at least 1.5× their regular rate beyond 40 hours in a workweek. Montana adds no daily-overtime rule on top of that federal floor. The calculator uses the standard 1.5× multiplier.

Montana follows the federal FLSA standard: at least 1.5× your regular rate for hours beyond 40 in a workweek, with no additional daily-overtime requirement. If you believe you're owed overtime, the Montana Department of Labor is the place to check. Our calculator uses the standard 1.5× multiplier.

Add regular earnings (rate × regular hours) to overtime earnings (rate × 1.5 × overtime hours), then subtract federal tax, Montana income tax and FICA. In Montana that leaves about 72.7% of each overtime dollar: $14,177 of the $19,500 that ten overtime hours a week adds over a year.

Against the 4 states Montana borders, the same ten overtime hours a week is worth $14,177 here: South Dakota keeps $992 more ($15,168), Wyoming keeps $992 more ($15,168), North Dakota keeps $857 more ($15,033) and Idaho leaves $42 less ($14,135). North Dakota, South Dakota and Wyoming are the only borders worth crossing for the tax alone.

Montana has no state sales tax (one of five states with no sales tax), which benefits big spenders. However, the state compensates with progressive income tax rates up to 6.75%. Many people moving to Montana for the 'no sales tax' benefit are surprised to find their income tax burden is actually higher than in some sales-tax states. A $75,000 earner pays an effective rate around 5.5%-6% (approximately $4,125-$4,500 annually), while the same earner in a flat-tax state like Pennsylvania would pay $2,300 (3.07% flat, though PA may have local EIT).
