Diesel mechanic pay in Montana after taxes: what you keep (2026)

The median diesel mechanic in Montana earned $57,060 a year in May 2024, which is $27 an hour for a full-time year, according to the Bureau of Labor Statistics. Half of the 1,110 diesel mechanics the BLS counts in Montana earned more than that and half earned less; the middle half of them sat between $47,390 and $67,050. That is the gross figure, before anyone takes anything. What you keep depends on Montana's tax, and Montana has a progressive state income tax with a top rate of 5.9%.

What the median diesel mechanic keeps in Montana

For a single filer on the median $57,060, taking the standard deduction and no other adjustments:

The state line is 4.1% of gross at this salary, approximated at 70% of the top bracket, which is where a middle income lands in most progressive states. Health insurance, retirement contributions and local taxes are not in it either; they vary by employer and by city.

Where Montana ranks for diesel mechanic pay

Of the 50 states, Montana ranks 40 of 50 on the gross median for diesel mechanics. The highest-paying state is Hawaii at $79,010 and the lowest is Alabama at $49,060. Gross rank is not take-home rank: a state with no income tax climbs several places once the state line is applied, and a high-tax state drops.

Where the diesel mechanic jobs are in Montana

The BLS count of 1,110 diesel mechanics is statewide. The metros with the most of that work are Billings, Missoula, Great Falls and Bozeman, which is where the median is set and where the upper quartile ($67,050 and above) is most often paid. Employers who could not hire locally and have filed with the Department of Labor are listed on the Montana openings page; those filings are the ones already paying to bring people in, and housing or transport is often part of the offer.

What people get wrong about diesel mechanic pay in Montana

• Quoting the mean. The BLS mean for Montana is $27 an hour, pulled up by the top earners. The median ($27) is what the typical diesel mechanic makes.
• Comparing gross across states. A $57,060 offer in Montana is $45,475 in hand; the same number in a no-tax state is $47,832.
• Forgetting the employer's share of insurance. A job that pays $55,060 with full health coverage can beat one that pays $60,060 without it.
• Treating the statewide median as the metro median. Billings pays differently from a rural county; ask for the figure for the place you are actually going.
