Montana has fourteen marginal tax brackets, ranging from 1.00% (the lowest Montana tax bracket) to 6.90% (the highest Montana tax bracket). Each marginal rate only applies to earnings within the applicable marginal tax bracket, which are the same in Montana for single filers and couples filing jointly. The Federal Income Tax, by contrast, has different tax brackets for married, single, and Head of Household taxpayers.

Our Montana tax brackets have been updated for tax year 2013. States often adjust their tax brackets on a yearly basis, so make sure you are using the current 2013 tax brackets!

What is my Montana tax bracket?

Technically, you don't have just one "tax bracket" - you pay all of the Montana marginal tax rates from the lowest tax bracket to the tax bracket in which you earned your last dollar. For comparison purposes, however, your Montana tax bracket is the tax bracket in which your last earned dollar in any given tax period falls.

You can think of the bracketed income tax as a flat amount for all of the money you earned up to your highest tax bracket, plus a marginal percentage of any amount you earned over that.

For earnings between $0.00 and $2,800, you'll pay 1.00%
For earnings between $2,800.00 and $4,900, you'll pay 2.00% plus $28.00
For earnings between $4,900.00 and $7,400, you'll pay 3.00% plus $70.00
For earnings between $7,400.00 and $10,100, you'll pay 4.00% plus $145.00

For earnings between $13,000.00 and $16,700, you'll pay 6.00% plus $398.00

Montana Tax Estimator

You can use the income tax estimator to the left to calculate your approximate Montana and Federal income tax based on the most recent tax brackets.

Keep in mind that this estimator assumes all income is from wages, assumes the standard deduction, and does not account for tax credits.

For a more detailed estimate that takes these factors into account, click "View Detailed Estimate" (this will will redirect to an external website).

Deductions

When calculating your Montana income tax, keep in mind that the Montana state income tax brackets are only applied to your adjusted gross income (AGI) after you have made any qualifying deductions.

Qualifying deductions might include an itemized deduction, the Montana standard deduction, exemptions for dependants, business expenses, etc.

Remember that Montana may have very different deduction laws from the Federal Income Tax, so you may have to write a whole new list of deductions for your Montana income tax return.
