How LLC Owners Save on Taxes in 2026

Montana 2026 Tax Changes — What the One Big Beautiful Bill Act (OBBBA ) and State Tax Cuts Mean for Residents

On January 1, 2026, the tax landscape for Montanans will undergo a historic and positive transformation. At the federal level, the One Big Beautiful Bill Act (OBBBA) has made the popular 2017 TCJA tax cuts permanent and introduced new benefits, avoiding the feared “tax cliff.”
This federal relief is amplified by Montana’s own recent tax cuts, which simplified the state’s brackets and lowered the top income tax rate to 5.9% starting in 2024. This creates a powerful “one-two punch” of tax savings for residents, ranchers, and business owners across Big Sky Country.
This guide provides a clear, localized breakdown of how these permanent federal and state tax laws will impact your income, business, and financial strategy in 2026 and beyond.

The Double Win: Federal and State Tax Relief

Permanent Federal Relief from OBBBA

OBBBA has made the federal tax picture much brighter for all Americans, including Montanans.

Montana’s New, Lower State Tax Rates

While not new for 2026, Montana’s recent tax reform is a critical piece of the puzzle. The state replaced its old, multi-bracket system with a simpler two-bracket system and lowered the top rate from 6.75% to 5.9%.

👉 Montana Impact: This state-level tax cut provides significant, permanent relief. When combined with the permanent federal cuts from OBBBA, it means Montanans will keep more of their hard-earned money at both the state and federal level.

New Federal Tax Breaks for Montana Residents

OBBBA also introduced several new federal deductions that will directly benefit many in Montana:

Montana-Specific Tax Considerations for 2026

A Major Win for Ranching, Agriculture, and Tourism

The permanent 20% federal QBI deduction is a huge benefit for Montana’s core industries. Ranchers, farmers, outfitters, guides, and other tourism-based businesses can continue to rely on this powerful federal deduction to lower their tax burden. This provides much- needed certainty for businesses that are the lifeblood of the Montana economy.

Real Estate and STRs in High-Growth Areas

For property owners in booming markets like Bozeman, Missoula, Kalispell, and Big Sky, OBBBA brings welcome news. The 100% bonus depreciation for qualified property is now permanent.  This allows real estate investors and STR hosts to immediately write off the cost of certain assets on their federal return, making strategies like cost segregation incredibly powerful.

Retirement Income in Montana

Montana taxes most forms of retirement income, including IRA and 401(k) distributions. The good news is that the permanent lower federal tax rates under OBBBA, combined with Montana’s new lower state rates, reduce the overall tax burden on these withdrawals, leaving more money in your pocket during your retirement years.
