Montana sales tax: baseline & example
Montana has no general statewide sales tax; resort and special taxes may apply. Ordinary income brackets differ from long-term capital gains rates.
For a $100 general taxable purchase, the 0% baseline produces $0.00 of tax and a $100.00 total before any additional local rate. This example assumes the purchase is fully taxable and no special caps or exemptions apply.
For your location, check the Montana tax authority, then enter only the additional rate above this page’s baseline. Statewide, county, city, and special district components must not be counted twice.
Montana income tax brackets
These schedules apply to taxable ordinary income after the applicable deductions and exemptions. They do not apply a top rate to every dollar. Source coverage: 2026-02-11.
| Single: income above | Rate | Joint: income above | Rate |
|---|---|---|---|
| $0.00 | 4.7% | $0.00 | 4.7% |
| $47,500.00 | 5.65% | $95,000.00 | 5.65% |
Worked example: $50,000 of state taxable income
At $50,000 of Montana taxable ordinary income, the stored schedule gives $2,373.75 for a single filer and $2,350.00 for a married couple filing jointly, before credits and excluded adjustments. These amounts use the same taxable income to illustrate the schedules; actual household deductions can differ. Federal tax is calculated separately in the tool.
What this Montana estimate leaves out
The sales estimate excludes product-specific rates, holidays, exemption certificates, shipping rules, and per-item caps. The income estimate excludes payroll and local income taxes, tax credits, capital gains, AMT, and AGI-based recapture, minimum taxes, or phaseouts. Entering gross salary as taxable income can overstate bracket tax. Use the linked state instructions to determine taxable income first.
