💰 Montana State Income Tax — What You Actually Pay
Montana has a two-bracket income tax system: 4.7% on lower income and a top rate of 5.65% for 2026 (reduced from 5.9% in 2025). A further reduction to 5.4% is scheduled for 2027. Montana has no state sales tax — one of only five states — which provides significant everyday savings.
📋 Tax Planning Tip for Montana Residents
Montana's zero sales tax is a major financial advantage. A household spending $40,000/year on goods saves $2,400–$3,200 compared to states with 6–8% sales tax. Montana also conforms to the federal standard deduction, providing a generous base exemption. The state recently expanded its Earned Income Tax Credit, which benefits lower and moderate-income working families.
🏦 Best Savings Accounts for Montana Residents
HYSA interest is taxed as ordinary income at both federal and Montana state rates. Your effective after-tax HYSA yield in Montana is approximately ~3.12% on a 4.50% APY account.

🏠 Montana Housing Market & Homebuying
Montana's housing market has seen significant growth driven by transplants from higher-cost states. Billings median home prices range from $320,000–$380,000, while Bozeman and Missoula have surged to $500,000–$650,000+. More affordable options exist in Great Falls, Helena, and Butte ($250,000–$340,000).
Down payment assistance: Montana Board of Housing offers the Bond Loan and MBOH Plus programs with below-market rates and down payment/closing cost assistance for first-time buyers. Income limits apply.
🏠 Montana Homebuyer Tip
Montana recently restructured its property tax system with a progressive split roll — primary residences and long-term rentals receive lower rates, while second homes, cabins, and short-term rentals pay higher rates. This benefits full-time residents but increases costs for vacation property owners. Montana also offers a property tax assistance program for seniors and disabled homeowners.
🏖️ Retirement in Montana — Tax Treatment
Montana taxes Social Security benefits following the federal formula — benefits are partially taxable for higher-income retirees. Pension and retirement income is taxed at Montana's progressive rates. Montana has no estate or inheritance tax. The state offers a property tax assistance program (PTAP) for seniors 62+ with household income under $48,610.
🏖️ Montana Retirement Tip
Montana's tax rates are moderate but the zero sales tax, no estate tax, declining income tax rates, and property tax assistance for seniors help offset the burden. Retirees relocating from high-cost Western states benefit from Montana's lower housing costs (outside Bozeman/Missoula) and dramatically lower consumption taxes — every purchase saves you 6–10% compared to neighboring states.
📚 Tools & Guides
📍 Understanding Personal Finance in Montana
Montana's cost of living varies dramatically by location — Bozeman has become a high-cost tech and outdoor lifestyle hub, while most of the state remains 5–10% below the national average. The state's economy centers on agriculture, energy, tourism, technology (Bozeman's growing tech scene), and outdoor recreation. Montana's zero sales tax makes it a popular shopping destination for residents of neighboring Idaho and Wyoming. The state's declining income tax rates (heading to 5.4% by 2027) and the progressive property tax split roll reflect an evolving approach to taxation that favors primary residents over vacation homeowners.
