How 1099 tax works in Montana
Montana taxes income on 2 graduated brackets for 2026, from 4.7% up to 5.65%. Because 1099 profit stacks on top of any other income, a second source can push part of it into the next bracket.
Montana allows its own standard deduction of $14,000 for a single filer, which is separate from the federal standard deduction.
On top of that sits the federal layer, which is the same wherever you live: self-employment tax plus federal income tax. The 1099 tax calculator hub works through how that half is built.
| Montana taxable income (single) | 2026 rate |
|---|---|
| $0 - $25,000 | 4.7% |
| $25,000 and up | 5.65% |

What the rate alone doesn't tell you about Montana
On the 2026 rate itself: top rate reduced from 5.9% in 2025. Essentially a flat tax with small lower bracket.
Montana is one of the twelve states that still taxes Social Security benefits, which matters if you are drawing benefits alongside self-employment income.
Montana is also one of five states with no general sales tax, so the total tax picture is lighter than the income tax line alone suggests.

Are there local income taxes in Montana?
The estimate above models federal, self-employment and state income tax only, it does not include any city, county or school-district income tax. The 2026 dataset carries no local-tax note for Montana, so check with the municipality where you live and work before relying on the state figure alone.
Does Montana reciprocity help if I do 1099 work across a state line?
Usually not. Montana has wage reciprocity with North Dakota, but reciprocity agreements cover wages paid by an employer, not self-employment income. A 1099 worker with income sourced to another state generally still files there and claims a credit at home.
When are quarterly estimated payments due?
Federal 1040-ES payments for the 2026 tax year are due April 15, 2026, June 16, 2026, September 15, 2026, January 15, 2027. Montana requires its own estimated payments; the 2026 dataset does not yet carry state-specific due dates, so confirm them with the Montana tax agency.
