Montana taxes and cost of living, explained
Montana uses a progressive state income tax, with rates rising to 5.65% for the top bracket. Combined with an average sales tax of 0.00% and an average effective property tax rate of 0.75%, these figures shape most household budgeting decisions in the state — from evaluating a job offer to estimating what home you can afford.
The six calculators below all use Montana's own current rates rather than national averages: paycheck withholding, state income tax, sales tax, property tax, a full mortgage (PITI) payment, and home affordability based on the standard 28/36 lending rule. Montana's minimum wage is $10.85/hour, and the data behind these numbers is sourced from the Tax Foundation, WalletHub, and state revenue departments.
