The Montana payroll calculator at the top of this page was designed to help employers get employee paychecks right. After adding input wage and W-4 information for each employee, it will do the rest of the work for you. And below is more information on MT payroll taxes and state rules you might find helpful. And if you have many hourly workers, you may find our Montana paycheck calculator helpful, too.
Montana payroll calculator that figures federal taxes
First of all, let’s give Uncle Sam his due. Here’s a quick rundown of the components that go into federal tax withholdings. For a more detailed explanation of all of the steps below, we invite you to head on over to our comprehensive step-by-step guide.
- Gross wages, which is simply the amount of money an employee has earned during the last pay period.
- For hourly employees, multiply the number of hours worked by their pay rate — and make sure you don’t forget to take overtime into consideration.
- For salaried employees, divide each employee’s annual salary by the number of pay periods you have over the course of a year.
- Bonuses, commissions, and tips are all part of gross wages as well.
- Subtract any pre-tax withholdings. If your employees have 401(k) accounts, flexible spending accounts (FSA), health savings accounts (HSA), or any other pre-tax withholdings, subtract them from gross wages prior to applying payroll taxes.
- Deduct federal income taxes, which can range from 0% to 37%. We won’t get into the nitty-gritty here, but you can find further withholding information through the IRS Publication 15-T.
- Deduct and match any FICA taxes to cover Social Security and Medicare taxes:
- For Social Security tax, withhold 6.2% of each employee’s taxable wages until they have earned $168,600 in a given calendar year. As an employer, you must match this tax.
- For Medicare tax, withhold 1.45% of each employee’s taxable wages until they have earned $200,000 in a given calendar year. You must also match this tax. For employees who earn more than $200,000 per year, you’ll need to withhold an Additional Medicare Tax of 0.9%, which brings the total employee Medicare withholding above $200,000 to 2.35%. You don’t need to match the Additional Medicare Tax. Only employees are responsible for paying this tax.
- Pay FUTA unemployment taxes, which is 6% of the first $7,000 of each employee’s taxable income. FUTA taxes come with a huge caveat that you should know about. You can claim a tax credit of up to 5.4% for the state unemployment tax you pay, as long as you pay in full and on time. It’s an easy way to save a whopping 90%, so make sure you take advantage! Only you as the employer are responsible for paying FUTA taxes, so you don’t need to withhold FUTA from your employees’ paychecks.
- Subtract any post-tax deductions. Most of your employees won’t have any post-tax deductions, but if they do, you will need to withhold things like court-ordered wage garnishments, child support, etc. Make sure you take these into consideration as well.
Montana state payroll taxes for 2024
Now that we’re done with federal payroll taxes, let’s look at Montana’s state income taxes. Under Montana’s new law, income tax will be be reduced to two brackets, with a 4.7% lower rate and a 5.9% higher rate. Montana doesn’t have any local taxes, so you only have to withhold for state taxes.
Montana state unemployment insurance (SUI)

More payroll calculators for Montana employers
Employers in Montana can use the calculator at the top of this page to quickly calculate their employees’ gross pay, net pay, and deductions in a few clicks. But sometimes a company has to do a little more math before they can cut paychecks. For example, do you own a business where employees earn tips from customers? Keep in mind that you are responsible for withholding taxes from your employees’ paychecks based on the tips they receive. Additionally, if an employee leaves for another employer, you’ll need to calculate their final pay. So, if you need a little more help with the number-crunching, check out some of the calculators below.
