How much should freelancers in Montana set aside for taxes?
As an estimate, a self-employed person in Montana with $50,000 of profit should set aside about 24% of that profit, rising to about 27% at $100,000. That covers federal income tax and self-employment tax, plus Montana state income tax. Here's where the numbers come from.

| Montana | |
|---|---|
| Structure | Graduated, 4.7% to 5.65% across 2 brackets |
| Top rate | 5.65% on single-filer income over $47,500 |

| Planning rate at $100,000 profit | 5.2% |
Picking a planning rate for a graduated tax
Montana taxes each slice of income at a higher rate as you earn more, so there isn't one number. Our calculator takes a single state rate, so use your planning rate: the average Montana rate on your income, before state deductions and credits. Because it skips those, it leans slightly high, which is the safe direction for a set-aside.
At $50,000 of profit that's about 4.7%; at $100,000 it's about 5.2%. Don't use the top rate (5.65%) unless your income is above $47,500. It would make you over-save.
| Single-filer taxable income over | Rate |
|---|---|
| $0 | 4.7% |
| $47,500 | 5.65% |

Montana estimated tax payments
Montana expects freelancers who will owe state tax to pay during the year too. Most states use the same four dates as the IRS, but a few don't, so confirm the dates and payment options with the Montana Department of Revenue.
An easy habit: when you make each federal quarterly payment, make the state one the same day.
