Payroll taxes
What are Montana employer payroll taxes on a first employee?
Short answer: on a first Montana employee paid $20 an hour for 40 hours a week, the federal employer payroll taxes are $3,224.40 a year, plus state unemployment tax at the rate on your notice. The federal piece is $3,182.40 of employer FICA plus $42.00 of net FUTA. Montana also charges state unemployment tax on the first $47,300.00 of wages, but the U.S. DOL January 2026 Significant Provisions table (PDF) lists the new-employer rate as an industry average rather than one published percentage, so this page does not invent a SUTA dollar amount. You will also withhold Montana income tax from the employee’s pay and send it to the state. That withheld tax is the employee’s money, not an extra employer cost, so it is left out of the dollar totals below. Workers’ comp and payroll software are extra costs, not payroll taxes.
Key takeaways
- Federal employer Social Security (6.2% up to the 2026 wage base of $184,500), employer Medicare (1.45% of all wages), and net FUTA (usually 0.6% on the first $7,000) apply in Montana the same way they do in every state (IRS Publication 15, IRS Topic 751, IRS Topic 759 (Form 940/FUTA)).
- Montana unemployment tax is administered by Montana Unemployment Insurance Division. The U.S. DOL January 2026 Significant Provisions table (PDF) lists a 2026 taxable wage base of $47,300.00 and a new-employer rate described as an industry average. Enter the rate on your unemployment insurance notice rather than guessing.
- State income-tax withholding is required in Montana. Look up current tables and registration on the Montana tax agency site or the IRS list of state government websites. Withholding is not an employer payroll-tax cost.
- Report the new hire within 20 days of the hire date. The official source is the ACF State New Hire Reporting contacts and program requirements; a reporting page is the ACF new-hire reporting directory.

When you hire a W-2 employee in Montana, the federal employer share has three parts, and they do not change just because the work is in Montana:
- Employer Social Security, 6.2% of wages up to the 2026 Social Security wage base of $184,500 (IRS Publication 15, IRS Topic 751). On $41,600 that is $2,579.20.
- Employer Medicare, 1.45% of all wages, with no wage-base cap. On $41,600 that is $603.20.
- FUTA, which is 6.0% on the first $7,000 of wages, usually reduced to a net 0.6% when you pay state unemployment tax on time (IRS Topic 759 (Form 940/FUTA)). For one employee that is $42.00. Credit-reduction states can owe more; check the current IRS credit-reduction list if you are unsure.
Together, those federal employer taxes are $3,224.40 on this $20-an-hour, full-year example. You also withhold the employee share of FICA and any federal income tax; those withheld amounts are the employee’s money, not an extra employer cost.
Montana unemployment tax (SUTA)
State unemployment insurance is administered by Montana Unemployment Insurance Division. The wage base and new-employer rate below come from the U.S. DOL January 2026 Significant Provisions table (PDF), which is the same source used in this site’s calculator. The DOL directory of state unemployment tax agencies is the official contact list if the agency URL changes.
The official DOL table lists a 2026 Montana taxable wage base of $47,300.00. It does not publish a single new-employer percentage; it describes the rate as an industry average. DOL lists Montana's new-employer rate as an industry average. Enter the rate on your state notice. On $41,600 of wages, SUTA would apply only to the first $47,300.00. Without a verified percentage, this page does not show a SUTA dollar total.
State income-tax withholding
Employers in Montana withhold state income tax from employee wages and send it to the state. The employee completes a state withholding form (or the federal W-4, where Montana uses it). The withheld amount is not an employer payroll tax, and this page does not invent a withholding dollar amount because it depends on the employee’s elections and current official tables. Register with the Montana tax agency. The IRS list of state government websites is a second official starting point if you need the department’s home page.
Disability, paid leave, and other state payroll contributions
Unlike states that publish one new-employer percentage in the DOL table, Montana’s new-employer rate is listed as an industry average. The wage base of $47,300.00 is official and is used in the calculator. Leave the SUTA rate blank until you have the notice, or type the percentage your agency assigned.
DOL lists Montana's new-employer rate as an industry average. Enter the rate on your state notice.
Montana employers withhold state income tax from employee wages. The amount depends on the employee’s withholding certificate and the current official tables, so this page does not invent a withholding dollar figure. Register and file with the Montana tax agency.
This page does not list a statewide disability or paid-family-leave payroll tax for Montana because no official 2026 employer rate was verified here for a separate program. If your agency notice mentions one, enter that rate as an additional cost; do not treat this omission as legal advice that no such program exists.
New-hire reporting in Montana
The official ACF matrix describes the Montana deadline as within 20 days of the hire date. The website line in that extract was incomplete or ambiguous, so this page links the ACF State New Hire Reporting contacts and program requirements rather than a guessed URL. Federal law requires reporting within 20 days unless the state requires it sooner.
New-hire reporting is a filing requirement, not a tax. It still belongs on a first-hire payroll checklist because missing the deadline can bring state penalties. See also paperwork to hire your first employee.
Worked example: $20 an hour, 40 hours, Montana
This example uses a round $20 wage so you can compare it with the site’s other $20-an-hour pages and with the state payroll taxes for a first employee index. It is not a claim about what helpers in Montana earn, and it leaves out workers’ comp, health coverage, retirement, paid time off, and payroll software.
| Line (one year, 2,080 hours) | Amount |
|---|---|
| Wages at $20.00/hour (2,080 hours) | $41,600.00 |
| Employer Social Security (6.2%) | $2,579.20 |
| Employer Medicare (1.45%) | $603.20 |
| FUTA (0.6% net, first $7,000) | $42.00 |
| Montana SUTA (rate from your notice, first $47,300.00) | Not invented here |
| Employer payroll taxes in this example | $3,224.40 federal + SUTA from your notice |
SUTA and FUTA are front-loaded: you pay them only until each wage base is met, so early pay periods cost more than later ones in the same calendar year. Employer Medicare continues all year, and employer Social Security continues until the federal wage base is met.
What this example leaves out
Workers’ compensation is insurance, not a payroll tax. Premiums vary by Montana class code, carrier, and payroll, and this site only prefills verified Indiana ICRB advisory rates when you select Indiana. See workers’ comp for a first employee. Overtime, bonuses, and benefits also change the total. For the week-by-week federal pattern at this same wage, see payroll taxes on a $20-an-hour employee.
