2026 Tax Overview
For tax year 2026, Montana uses two ordinary-income rates: 4. Montana has no general statewide sales tax. For relocation planning, compare the exact tax base, effective year and address rather than relying on a combined ?tax burden? score.
Individual Income Tax
For tax year 2026, Montana uses two ordinary-income rates: 4.7% and 5.65%. Thresholds differ by filing status; taxpayers should use the official 2026 table. Montana also has separate treatment for net long-term capital gains rather than simply excluding all gains. Marginal or statutory rates should not be confused with effective tax after deductions, credits, residency allocation and federal interactions.
Sales, Excise, or Gross Receipts Tax
Montana has no general statewide sales tax. Targeted state and local taxes can still apply to lodging, cannabis, rental vehicles and certain resort-community transactions. Product exemptions, sourcing rules, local additions and special taxes on lodging, vehicles or prepared food can change the final amount.
Property Tax
Montana begins a materially revised property-tax structure in 2026, including distinctions involving homesteads, long-term rentals and other property. Parcel classification and eligibility must be verified through the Property Tax Hub. Before buying, review the current assessment and bill, taxing districts, exemptions, appeal deadlines and whether benefits reset after transfer.
Other Important Taxes
The Montana earned-income tax credit increases to 20% of the federal credit beginning in 2026. Estate, inheritance, fuel, lodging, conveyance and industry-specific taxes should be checked separately; absence from this overview does not imply exemption.
Retirement Considerations
Retirees should verify the state treatment of Social Security, pensions and retirement-account distributions using the final 2026 return instructions. Property relief often depends on age, income, occupancy and filing deadlines. Federal tax, healthcare, insurance and consumption taxes remain part of the relocation calculation.
Relocation Context
A lower headline income-tax rate can be offset by housing, property tax, local consumption taxes or insurance. Remote workers and owners of rental property or businesses may owe tax in more than one jurisdiction. Compare the same household income, filing status, home value and spending pattern across locations.
What to Verify Before Moving
Confirm the final tax-year 2026 form, exact local consumption-tax rate, parcel assessment, residency start date and source-income treatment. Investors should review capital-gains rules; business owners should review entity, gross-receipts, franchise and licensing obligations independently.
Property-use classification is especially important in 2026.
