Montana 401k and retirement tax guide - 2026
How Montana taxes 401k contributions and retirement distributions
Montana retirement tax overview
Montana taxes most retirement income but provides a pension income exemption for qualifying retirees. Montana's natural environment makes it attractive for retirement despite its tax rates.
Montana allows a pension and annuity income exemption of up to $4,370 for qualifying retirees. Montana's relatively high income tax rate means careful tax planning is important for retirees relying on 401k distributions.
Federal 401k rules that apply in Montana
Regardless of Montana state tax treatment, federal rules govern 401k contribution limits. In 2026 the 401k contribution limit is $23,500 per year ($31,000 if age 50 or older with catch-up contributions). Traditional 401k contributions reduce your federal taxable income dollar-for-dollar in the year contributed. You pay ordinary income tax when you withdraw in retirement. Withdrawals before age 59.5 are subject to a 10% federal penalty plus income taxes unless an exception applies.
