Take-Home Pay in Montana: No Sales Tax, and It Taxes Social Security

  • Montana has two brackets, 4.7% and 5.65%, above a standard deduction that matches the federal one at $16,100.
  • On $85,000 a single filer pays $3,442 in Montana income tax and takes home $65,186.
  • Montana is one of only five states with NO general sales tax, which is the largest thing this article's figures do not show.

Montana sits at an unusual intersection. It is one of only five states with no general sales tax — which makes its overall tax burden lighter than its income tax rate suggests. And it is one of only eight states that still tax Social Security — which makes its retirement position heavier than its reputation suggests.

The income tax itself is straightforward: 4.7% and 5.65%, above a standard deduction that matches the federal one at $16,100.

On $85,000 a single filer pays $3,442 and takes home $65,186.

A note before you start. This is general education, not tax advice. Federal figures are tax year 2026, from IRS Revenue Procedure 2025-32 and the Social Security Administration; Montana's rates, deduction, capital gains treatment and retirement rules come from this site's own sourced 50-state dataset, citing MCA Title 15 chapter 30 and the Department of Revenue's Form 2 and Publication 1. Every dollar figure is computed by the same engine the site's calculators use, on a single filer taking the standard deduction with no dependents or pre-tax deferrals unless stated. Property tax is discussed qualitatively.

1. What Montana takes

Across incomes, single filer:

But the figure that matters most is not in that table, because Montana raises no sales tax at all. A household spending $50,000 a year in Montana pays nothing on it that a household in Tennessee or Louisiana would pay several thousand dollars on. That offset is real and it is invisible in every income tax comparison.

2. The brackets

Married-joint thresholds are exactly double: 5.65% begins at $95,000 of taxable income. Head of household sits between, at $71,250.

For a single filer on $85,000: $16,100 sheltered, $68,900 taxable, $47,500 of it at 4.7% and $21,400 at 5.65% — $2,232 plus $1,209, or $3,442.

Two brackets, and the split point is high enough to matter. Unlike Kansas, where the two rates are 0.38 points apart, Montana's differ by nearly a full point, and the threshold sits where a lot of professional salaries land. An $85,000 earner's next raise is taxed at 5.65%; a $55,000 earner's at 4.7%.
