Montana Salary Tax Calculator 2026 – Net Pay Estimator
MT 2‑Bracket System: 4.7% – 5.65%
Montana uses the federal standard deduction to compute state taxable income.
How Does the Montana Salary Tax Calculator Work?
This calculator estimates your net (take‑home) pay after subtracting:
- Federal Income Tax – progressive rates from 10% to 37%.
- Montana State Income Tax – two brackets: 4.7% on the first $47,500 (single) / $95,000 (married) / $71,250 (head), and 5.65% on income above those thresholds.
- FICA – Social Security (6.2% up to $184,500) and Medicare (1.45% plus 0.9% additional above $200,000).
Montana uses the federal standard deduction to determine taxable income for both federal and state purposes. The calculator applies the correct deduction based on your filing status.
Formula and Calculation Method
Step 1: Determine Taxable Income
Federal taxable income = Gross salary – Standard deduction (2026 amounts):
| Filing Status | Standard Deduction |
|---|---|
| Single / MFS | $16,100 |
| Married Filing Jointly | $32,200 |
| Head of Household | $24,150 |
Montana uses the same taxable income figure (no separate state deductions).
Step 2: Calculate Federal Income Tax
Apply the 2026 federal brackets to the taxable income. Brackets are progressive, with rates: 10%, 12%, 22%, 24%, 32%, 35%, 37%.
Step 3: Calculate Montana State Income Tax
Montana has two brackets (2026):
- 4.7% on income up to the threshold (based on filing status).
- 5.65% on income exceeding the threshold.
Thresholds:
- Single / MFS: $47,500
- Married Filing Jointly: $95,000
- Head of Household: $71,250
Step 4: Calculate FICA Taxes
- Social Security: 6.2% of gross wages up to $184,500.
- Medicare: 1.45% of all gross wages; an additional 0.9% (total 2.35%) applies to wages over $200,000.
Step 5: Compute Net Pay
Net annual salary = Gross salary – (Federal tax + State tax + Social Security + Medicare).
Then the calculator divides by 12, 26, or 52 to show monthly, bi‑weekly, or weekly amounts.
