SECTION B: FICA & Federal Deductions in Montana
Regardless of state residency, every worker in Montana must contribute to federal taxation and Social Security / Medicare security programs under the Federal Insurance Contributions Act (FICA):
- Federal Income Tax (IRS 2026): Calculated using 2026 IRS withholding tables after subtracting the 2026 Federal Standard Deduction ($15,000 for single filers; $30,000 for married filing jointly). On an $85,000 single salary, federal income tax equals $10,314.00 annually ($396.69 bi-weekly).

- Medicare Tax (FICA): Assessed at 1.45% on all earned wages without an income cap. On an $85,000 salary, Medicare withholding equals $1,232.50 per year ($47.40 bi-weekly). High earners with income exceeding $200,000 ($250,000 for married joint filers) are subject to an Additional Medicare Tax of 0.9%.

SECTION D: Form W-4 & Montana State Withholding Guidance
To ensure your employer accurately withholds state and federal taxes from your paychecks in Montana:
- State Withholding Document: Montana uses Form MW-4 to establish state income tax withholding. You should complete Form MW-4 upon hire or when updating your filing status to select correct state exemption allowances.
- Pre-Tax Deduction Offsets: Electing pre-tax 401(k) contributions (up to $23,500 in 2026), Health Savings Account (HSA) contributions, or pre-tax health insurance premiums lowers your taxable wage baseline for federal tax and Montana state tax.
