Montana’s Progressive Income Tax Rates and Brackets for 2025
Knudsen Law Firm, PLLC explains that Montana’s progressive income tax system for 2025 operates through two distinct brackets. Taxpayers are subject to a 4.7% rate on taxable income up to $21,100 for single filers or $42,200 for married filing jointly.
Any income above these thresholds incurs a 5.9% tax rate. The firm advises that these rates apply after accounting for standard or itemized deductions. Montana incorporates the federal standard deduction into its income starting point, which can significantly reduce taxable income for many residents. While certain tax-exempt investments may avoid these rates, ordinary income is taxed progressively through these brackets. Audit defense services are available for taxpayers who need assistance with state or federal tax examinations.
For example, on a $350,000 income, the tax liability would be approximately $992 for the first $21,100 (at 4.7%) plus $19,405 for the remaining $328,900 (at 5.9%), resulting in a total tax of $20,397 before applying any credits.
Standard and Itemized Deductions for Montana Taxpayers
Knudsen Law Firm, PLLC recognizes that Montana taxpayers calculate their state taxable income using their federal taxable income as a starting point, which includes the federal standard deduction amounts of $15,000 (single), $30,000 (married filing jointly), or $22,500 (head of household). While Montana doesn’t provide its own standard deduction, taxpayers aged 65 or older qualify for an additional age-based subtraction of $5,500 per person. This age-based subtraction will be adjusted annually for inflation beginning in 2025.
For itemized deductions, Montana follows federal guidelines—taxpayers who itemize on their federal returns will apply those same deductions to their Montana returns, subject to certain state-specific modifications. Our experienced tax attorneys can assist with navigating these deductions and ensuring compliance with both federal and state requirements.
Standard Deduction Amounts
Knudsen Law Firm, PLLC helps clients understand and navigate Montana’s two key deduction types: standard deduction and itemized deductions. The standard deduction reduces taxable income without documentation requirements. Montana’s deduction amounts differ from federal levels:
| Filing Status | Montana | Federal |
|---|---|---|
| Single | $4,500 | $15,000 |
| Married Filing Jointly | $11,500 | $30,000 |
| Senior (65+) Single | $10,000* | $16,850 |
| Senior (65+) Married | $22,500* | $33,700 |
| Head of Household | $4,500 | $22,500 |
*Includes senior subtraction
As your tax advisors since 2016, we emphasize that Montana’s standard amounts remain fixed, unlike federal deductions, with only the senior subtraction receiving inflation adjustments starting 2025. Our experienced attorneys ensure proper Montana residency verification and filing status selection. We guide clients through Form 2 completion, helping reduce state taxable income before Montana’s 4.7% or 5.9% tax rates apply. Contact our team for personalized assistance with IRS disputes, audits, and strategic tax planning. Taxpayers choosing itemized deductions must carefully track qualifying expenses such as mortgage interest, medical costs, and charitable contributions to maximize their Montana state tax refund.
Common Itemized Expenses
When should you itemize deductions instead of claiming Montana’s standard deduction? According to Knudsen Law Firm, PLLC, taxpayers benefit from itemizing when their total deductions exceed the standard amount. As tax law specialists since 2016, we help clients identify various Montana deductions that can significantly reduce taxable income.
Key itemized expenses include:
- Medical expenses – Long-term care premiums and health insurance costs
- Federal taxes – Up to $5,000 ($10,000 joint) of federal income tax paid
- Interest payments – Mortgage interest on acquisition debt up to $750,000
- State-specific deductions – Montana 529 plans, ABLE accounts, and first-time homebuyer savings accounts
Our experienced tax attorneys can also help you identify additional deductible expenses such as workers’ compensation benefits and unemployment compensation. State income tax refunds become deductible if they’re taxable federally. Our team provides personalized guidance to help maximize your Montana tax savings through careful calculation and strategic planning.
How Capital Gains Are Taxed in Montana
How Capital Gains Are Taxed in Montana
According to Knudsen Law Firm, PLLC, Montana taxes capital gains as ordinary income, with rates ranging from 3.0% to 4.1% based on income level. The first $21,100 of capital gains minus ordinary income is taxed at 3.0%, with amounts above this threshold subject to progressively higher rates up to 4.1%.
The firm notes that Montana’s tax treatment differs from federal regulations by not distinguishing between short-term and long-term gains. Taxpayers must pay federal capital gains tax before calculating Montana’s state tax on those gains.
Knudsen Law Firm, PLLC explains that Montana’s capital gains tax rates fall in the middle range compared to other states—higher than states without capital gains tax like Florida but significantly lower than California’s 14%. Their tax attorneys recommend strategic tax planning approaches, including carefully timed asset sales and loss harvesting to reduce combined federal and state tax liability.
Recent Tax Rate Changes and Historical Trends
At Knudsen Law Firm, PLLC, we’ve observed Montana’s top income tax rate decrease from 6.9% to 5.9% over the past four years, representing a major change in state tax policy. Our tax attorneys are monitoring Governor Gianforte’s 2025 budget proposal, which would further reduce the top rate to 4.9%, placing Montana at a competitive advantage compared to Idaho’s 5.8% rate.
As tax law specialists, we help clients navigate these ongoing changes while working within Montana’s two-tier progressive structure, which maintains brackets at $21,100 for single filers and $42,200 for married couples filing jointly. Our experienced legal team assists clients in understanding how these tax reforms affect their financial planning and compliance obligations.

Montana’s Earned Income Tax Credit Expansion

Comparing Montana’s Tax Rates to Neighboring States
Knudsen Law Firm, PLLC observes that Montana’s progressive income tax rates range from 4.7% to 5.9% for most taxpayers in 2025, positioning the state’s tax burden between its neighbors’ widely varying approaches. We assist clients in understanding these tax environment comparisons to make informed financial decisions.
Montana’s 4.7%-5.9% income tax rates position the state between Wyoming’s zero-tax advantage and Idaho’s higher burden.
Our tax attorneys analyze the following state income tax comparisons:
- Wyoming: No state income tax versus Montana’s 4.7%-5.9% rates
- North Dakota: 1.1%-2.9% rates significantly undercut Montana’s structure
- Idaho: 1.125%-6.5% rates exceed Montana’s top marginal rate
- Capital gains: Montana’s 3% preferential rate beats Idaho’s ordinary income treatment
Knudsen Law Firm’s tax specialists note that Montana’s tax structure proves more favorable than Idaho’s but less competitive than Wyoming’s zero-tax environment or North Dakota’s lower rates. Our firm helps clients leverage Montana’s capital gains advantage for strategic planning opportunities unavailable in neighboring states.
Filing Status Options and Their Impact on Tax Obligations
At Knudsen Law Firm, PLLC, we understand how filing status affects your Montana tax obligations—impacting tax rates, deductions, and overall liability. Since 2024, Montana requires your filing status to match your federal return, with options including Single, Married Filing Jointly, Married Filing Separately, Head of Household, or Qualifying Surviving Spouse.
Our tax attorneys regularly assist clients with filing status decisions, particularly regarding joint versus separate filing options. While married filing separately involves additional complexity through dual returns, limited deductions, and reduced credits compared to joint filing, we can help determine if Montana’s “Married Filing Separately – Spouse Not Filing” status applies for nonresident spouses without Montana-source income.
The Knudsen Law Firm team evaluates how your selected status affects standard deduction amounts, itemized deduction eligibility, and underpayment interest calculations. Our experienced attorneys work to identify the filing status that minimizes your total tax liability while ensuring compliance with both federal and state requirements. Contact our office, established in 2016, for personalized assistance with your tax planning needs.
