As a single filer, you receive a standard deduction of $16,100 for 2026. Your taxable income is your gross salary minus this deduction. The federal tax brackets for single filers are narrower than for married filers — for example, the 12% bracket ends at $49,850 for single filers vs $99,700 for married filing jointly. This means single filers hit higher marginal rates sooner on the same income.
The effective tax rate for single filers in Montana ranges from 17.9% at $40K to 31.9% at $300K. The progressive bracket system ensures that lower earners keep a higher percentage of their income, while higher earners pay more in both absolute dollars and as a percentage.
How much difference does filing status make? Here’s a side-by-side at three key salary levels (assuming one earner):
| Salary | Single Take-Home | Married Take-Home | Difference | Monthly Diff |
|---|---|---|---|---|
| $75K | $58,783 | $61,868 | +$3,085 | +$257/mo |
| $100K | $75,453 | $81,038 | +$5,585 | +$465/mo |
| $150K | $108,242 | $117,566 | +$9,324 | +$777/mo |
In Montana, married filing jointly consistently results in a marriage bonus at these salary levels, averaging $5,998/year. The bonus is largest at higher incomes because the doubled standard deduction and wider brackets shelter more income from higher marginal rates. This analysis assumes one earner — when both spouses have similar incomes, the bonus shrinks or may become a penalty as combined income pushes into higher brackets.
Montana uses a graduated income tax with rates of 4.7-5.65%. For married filers, Montana’s brackets may be wider than for single filers, similar to the federal system, though the exact ratios vary. With a moderate top rate of 5.65%, the difference between filing statuses is less dramatic at the state level than it is federally. Some states follow federal deductions closely while others have their own state-specific deductions and exemptions.
