Montana Paycheck Calculator (Hourly)

How the Montana Paycheck Calculator Works

This Montana paycheck calculator hourly tool estimates your take-home pay by subtracting federal income tax, Montana state income tax (progressive rates of 4.7% and 5.9% for 2026), and FICA (Social Security plus Medicare) from your gross earnings. Montana is one of only five states with no sales tax, meaning your calculated take-home pay represents true purchasing power without an additional consumption tax eroding your paycheck at the register.

The core formula:

Take-Home = Gross Pay - Federal Tax - Montana State Tax - Social Security - Medicare $$P_{\text{net}}=P_{\text{gross}}-T_{\text{fed}}-T_{\text{MT}}-T_{\text{SS}}-T_{\text{Med}}$$

Annual gross pay equals your hourly wage multiplied by hours per week multiplied by 52 weeks. To convert that annual figure into per-period amounts, divide by 52 for weekly, 26 for biweekly, 24 for semi-monthly, or 12 for monthly pay. Use our salary calculator to translate between hourly and annual figures if you need to compare a job offer stated as an annual salary against your current hourly rate.

Federal income tax uses the 2026 progressive brackets. For a single filer, the first $11,925 of taxable income is taxed at 10%, income from $11,925 to $48,475 at 12%, income from $48,475 to $103,350 at 22%, income from $103,350 to $197,300 at 24%, income from $197,300 to $250,525 at 32%, and income from $250,525 to $626,350 at 35%. For married filing jointly, the bracket thresholds double through the 22% bracket ($23,850, $96,950, $206,700). The 2026 standard deduction is $15,000 for single filers, $30,000 for married filing jointly, and $22,500 for head of household. Montana state tax applies its own two-bracket progressive system to Montana taxable income (gross minus the Montana standard deduction, which matches federal amounts, minus any pre-tax retirement contributions). Social Security is 6.2% on wages up to $176,100, and Medicare is 1.45% with an additional 0.9% surtax on wages above $200,000 (single) or $250,000 (married).

Montana Hourly Paycheck Tax Breakdown

Montana consolidated its income tax from seven brackets (ranging from 1% to 6.75%) down to two brackets under Senate Bill 399 in 2023. The current structure taxes the first $20,500 of taxable income at 4.7% and everything above $20,500 at 5.9%. This simplification was part of Governor Gianforte's broader tax reform agenda, which also included increasing the standard deduction to match federal levels and eliminating several itemized deduction categories unique to the old Montana code.

Montana's economy is distinctly shaped by its geography — the fourth-largest state by area with just over 1.1 million residents, giving it one of the lowest population densities in the nation. The state's major economic drivers include:

• Agriculture and ranching: Montana ranks in the top five nationally for wheat production, with over 5.3 million acres harvested annually. Cattle ranching is the largest agricultural revenue source, with approximately 2.6 million head of cattle across the state. The Billings area serves as the commercial hub for Montana's agricultural economy, and many ranch workers earn seasonal wages that fluctuate significantly between summer grazing and winter feeding operations.
• Mining: Montana has a storied mining history dating to the Butte copper boom of the late 1800s. Today the state produces gold, silver, copper, palladium, and platinum. The Stillwater Mine near Nye is the only palladium and platinum mine in the United States, employing over 1,500 workers. Mining wages in Montana typically range from $25 to $55 per hour depending on the mineral and the worker's specialization.
• Tourism: Glacier National Park drew over 2.9 million visitors in 2023, and Montana's portion of Yellowstone National Park (the north and northeast entrances via Gardiner and Cooke City) generates substantial seasonal employment. Big Sky Resort, Whitefish Mountain Resort, and the charming towns along the Rocky Mountain Front employ thousands of seasonal workers in hospitality, guiding, and outdoor recreation. Tourism jobs often pay $14 to $22 per hour with seasonal variability.
• Oil and gas: The Bakken formation in eastern Montana (extending into North Dakota) produces significant oil revenue. Roughnecks and drilling technicians in the Sidney and Glendive area earn $28 to $65 per hour during active drilling seasons. The Bakken boom brought rapid wage growth to eastern Montana communities starting around 2010.
• Military: Malmstrom Air Force Base near Great Falls is one of three U.S. intercontinental ballistic missile bases, employing approximately 3,500 military and 800 civilian personnel. Military wages follow federal GS and military pay scales, exempt from Montana state tax for active-duty members but subject to Montana tax for civilian employees.

Your Montana paycheck deductions come from:

• Federal income tax: Progressive 2026 brackets; estimate your full-year federal liability with our income tax calculator.
• Montana state income tax: 4.7% on the first $20,500 of taxable income, 5.9% on income above $20,500 (after the standard deduction).
• Social Security: 6.2% on wages up to $176,100.
• Medicare: 1.45% on all wages, plus 0.9% surtax above $200,000 single or $250,000 married.

Variable Definitions

Hourly Wage: Your gross pay per hour before any deductions. Montana hourly workers span a wide range: the state minimum wage of $10.55 is common in rural retail and food service, a Stillwater Mine palladium miner earns roughly $35 to $45 per hour, a registered nurse at Billings Clinic averages about $38 per hour, a Bakken oil field technician earns $30 to $55 per hour depending on the rig and role, a lumber mill worker in western Montana earns approximately $22 per hour, and a seasonal Glacier National Park lodge worker earns $15 to $19 per hour plus housing. All face the same two-bracket Montana rate structure but land in different federal brackets.

Hours per Week: Total hours worked each week. Standard full-time is 40 hours. Montana follows federal Fair Labor Standards Act overtime rules requiring 1.5x pay above 40 hours per week for non-exempt workers. Agricultural workers are generally exempt from overtime requirements under both federal and Montana law, which affects a significant portion of the Montana workforce given the state's heavy reliance on farming and ranching. Oil field workers in the Bakken region frequently log 60 to 84 hours per week during drilling operations, with overtime pay substantially boosting their effective annual earnings.

Pay Frequency: How often you receive a paycheck. Weekly equals 52 paychecks per year, biweekly equals 26, semi-monthly equals 24, and monthly equals 12. Montana law requires employers to pay employees at least twice per month. Biweekly is the most common frequency for hourly workers. A $22/hour worker at 40 hours per week earns $45,760 annually regardless of frequency, but per-paycheck gross is $880 weekly versus $1,760 biweekly versus approximately $1,907 semi-monthly.

Filing Status: Your federal tax filing status, which determines your standard deduction and bracket thresholds for both federal and Montana purposes. Single filers use the $15,000 standard deduction for both federal and Montana. Married filing jointly uses $30,000 for both. Head of household uses $22,500 for both. Montana's standard deduction now matches federal amounts exactly, which simplifies the calculation and means your Montana taxable income equals your federal taxable income for most workers without complex itemized deductions.

Pre-Tax Deduction: Percentage of gross pay contributed to 401(k), 403(b), traditional IRA, or HSA. Montana follows federal treatment, so each dollar contributed reduces both federal and Montana taxable income. For a Billings Clinic nurse earning $79,000 contributing 6% ($4,740), federal tax savings of approximately $1,043 (at the 22% marginal rate) plus Montana savings of roughly $280 (at the 5.9% marginal rate) total about $1,323 in annual combined tax savings. Montana also offers a contribution deduction for the Achieve Montana 529 education savings plan, with up to $3,000 per contributor ($6,000 married) deductible on the Montana return.

Worked Example 1: Montana Hourly Paycheck at $18/Hour

A single filer earning $18/hour, working 40 hours/week, biweekly pay, with a 5% pre-tax 401(k) contribution. This profile fits a seasonal worker at a Glacier National Park concessionaire or an entry-level warehouse worker in Billings:

1. Annual gross: $18 x 40 x 52 = $37,440
2. Pre-tax 401(k): $37,440 x 5% = $1,872
3. Adjusted gross: $37,440 - $1,872 = $35,568
4. Federal taxable income: $35,568 - $15,000 (standard deduction) = $20,568
5. Federal tax: ($11,925 x 10%) + ($8,643 x 12%) = $1,192.50 + $1,037.16 = $2,229.66
6. Montana taxable income: $35,568 - $15,000 (MT standard deduction) = $20,568
7. Montana state tax: $20,500 x 4.7% + $68 x 5.9% = $963.50 + $4.01 = $967.51
8. Social Security: $35,568 x 6.2% = $2,205.22
9. Medicare: $35,568 x 1.45% = $515.74
10. Total deductions: $1,872 + $2,229.66 + $967.51 + $2,205.22 + $515.74 = $7,790.13
11. Annual take-home: $37,440 - $7,790.13 = $29,649.87
12. Biweekly take-home: $29,649.87 / 26 = $1,140.38

Worked Example 2: Montana Hourly Paycheck at $45/Hour

A married filing jointly worker earning $45/hour, working 40 hours/week, biweekly pay, with a 10% pre-tax 401(k) contribution. This profile fits an experienced Bakken oil field technician, a senior mining engineer at the Stillwater Mine, or a physician assistant at a Billings or Missoula hospital:

1. Annual gross: $45 x 40 x 52 = $93,600
2. Pre-tax 401(k): $93,600 x 10% = $9,360
3. Adjusted gross: $93,600 - $9,360 = $84,240
4. Federal taxable income: $84,240 - $30,000 (married standard deduction) = $54,240
5. Federal tax (married brackets): ($23,850 x 10%) + ($30,390 x 12%) = $2,385 + $3,646.80 = $6,031.80
6. Montana taxable income: $84,240 - $30,000 (MT married standard deduction) = $54,240
7. Montana state tax: ($20,500 x 4.7%) + ($33,740 x 5.9%) = $963.50 + $1,990.66 = $2,954.16
8. Social Security: $84,240 x 6.2% = $5,222.88
9. Medicare: $84,240 x 1.45% = $1,221.48
10. Total deductions: $9,360 + $6,031.80 + $2,954.16 + $5,222.88 + $1,221.48 = $24,790.32
11. Annual take-home: $93,600 - $24,790.32 = $68,809.68
12. Biweekly take-home: $68,809.68 / 26 = $2,646.53

This couple's effective Montana state rate is approximately 3.16% of gross income ($2,954.16 / $93,600). The 10% 401(k) contribution saves them approximately $1,123 in federal tax and $552 in Montana state tax annually. Because Montana has no sales tax, this family's $68,810 take-home is not further eroded by consumption taxes on groceries, clothing, or household goods, unlike in neighboring Idaho where a 6% sales tax applies to most purchases.

Edge Cases and Advanced Scenarios

No sales tax offset — Montana's hidden advantage: When comparing Montana's 4.7%-5.9% income tax to states with lower or no income tax, it is essential to account for Montana's zero sales tax. A family earning $70,000 and spending $40,000 annually on taxable goods would pay $2,400 in sales tax in Idaho (6%), $2,000 in North Dakota (5%), or $1,600 in Wyoming (4% state rate, often 5-6% with local additions). Montana's income tax on $70,000 (single, after the $15,000 deduction) is approximately $3,290. After subtracting the sales tax savings of $1,600 to $2,400, Montana's effective total tax disadvantage versus a no-income-tax state like Wyoming shrinks to roughly $900 to $1,700 — far less than the income tax alone suggests. Use our federal income tax percentage calculator to see how federal taxes layer on top of state obligations.

Seasonal tourism workers and variable hours: Montana's tourism industry employs tens of thousands of seasonal workers, particularly from May through September in the Glacier and Yellowstone gateway communities (West Yellowstone, Gardiner, Whitefish, East Glacier Park). These workers often earn $15 to $22 per hour during the season but may work only 20 to 30 weeks per year. A seasonal worker earning $18/hour for 24 weeks at 45 hours/week earns $19,440 gross for the season. After the $15,000 standard deduction, Montana taxable income is just $4,440, taxed entirely in the 4.7% bracket for a Montana tax of $209. Many seasonal tourism workers effectively pay very low Montana state tax because their annual earnings fall mostly within the standard deduction. Workers should enter their average annualized hours rather than peak-season hours for the most accurate take-home estimate.

Cross-border workers commuting to Wyoming or South Dakota: Montana residents who commute across the border to work in Wyoming or South Dakota owe no state income tax on those wages because neither state levies an income tax. However, the reverse is common as well: Wyoming and South Dakota residents working in Montana do owe Montana income tax on their Montana-source wages. A Sheridan, Wyoming resident commuting to Billings for work must file a Montana nonresident return and pay Montana's 4.7%-5.9% tax on their Billings wages. Montana does not have reciprocal agreements with any neighboring state. Workers in the Sidney-Williston corridor straddling the Montana-North Dakota border should compare both states' obligations using this calculator and the North Dakota paycheck calculator — North Dakota's flat 1.95% rate is significantly lower than Montana's rates.

Social Security wage base cap and high-earning Montana professionals: Workers earning above $176,100 annually stop paying the 6.2% Social Security tax on excess wages. This is relevant for Montana's higher-paid professionals — senior mining engineers, oil field managers, experienced physicians at Billings Clinic or St. Patrick Hospital in Missoula, and senior faculty at the University of Montana or Montana State University. A mining manager earning $200,000 pays Social Security of $10,918.20 (capped at the $176,100 threshold) rather than $12,400. The remaining $23,900 above the cap avoids the 6.2% charge but is still subject to the 1.45% Medicare tax plus the 0.9% Additional Medicare Tax surtax since it exceeds the $200,000 single threshold.

Agricultural and ranch workers: Montana's agricultural sector employs a significant workforce that faces unique payroll considerations. Farm and ranch workers are generally exempt from federal overtime requirements under the FLSA agricultural exemption, meaning they can work 50 to 70 hours per week during calving, haying, and harvest seasons without overtime premium pay. A ranch hand earning $16/hour working 60 hours per week earns $960 per week at straight time (no overtime), not $1,120 as a non-exempt worker would. Additionally, small farm employers (those who used fewer than 500 person-days of agricultural labor in any calendar quarter of the preceding year) are exempt from federal minimum wage requirements, though Montana's state minimum wage of $10.55 still applies. These workers should enter their actual straight-time hours and wage rate for accurate Montana paycheck calculations.

What to Do with Your Montana Paycheck Result

• Compare your Montana take-home to what you would earn in neighboring states. Use the Idaho paycheck calculator to compare Idaho's flat 5.695% rate, but remember that Idaho charges 6% sales tax while Montana charges none.
• If you are considering a move to Wyoming or South Dakota for tax savings, calculate the true difference by factoring in Montana's zero sales tax advantage against those states' sales taxes (4% Wyoming, 4.5% South Dakota) and potentially higher property taxes or costs of living.
• Use our federal income tax percentage calculator to check your effective federal rate, then combine it with your Montana effective rate to understand your total income tax burden.
• If you work seasonal hours in tourism, agriculture, or oil and gas, run the calculator for your actual annualized income rather than your peak-season hourly rate to avoid overestimating your tax obligations.
