Chad Mangum | Mar 26 2026 15:00

The One Big, Beautiful Bill Act (OBBBA) introduces a wide range of permanent and temporary tax changes that may directly affect individuals and families here in Bozeman and across the Gallatin Valley. This isn’t just another headline—it's new legislation that could reshape your financial plans, whether you’re ranching outside Belgrade, running a small business in Livingston, or raising a family right here in Bozeman. If you’re feeling unsure about what it all means, you’re not alone. Our goal is to help you understand the major changes and consider what steps may make sense moving forward.

Income Tax, Deductions & Credits

The lower income tax brackets originally introduced under the TCJA are now permanent, meaning Bozeman-area residents will continue to benefit from these reduced rates. Income thresholds have also been updated to better reflect today’s economic conditions.

You’ll also see the higher standard deduction remain in place, with annual inflation adjustments—helping preserve its value over time for Montana households.

The Child Tax Credit has been updated with new refundable and nonrefundable portions. Because phaseouts are tied to income, your eligibility may change depending on your household structure and earnings.

A new deduction—up to $10,000 in car loan interest—is available for qualifying vehicles assembled in the United States. With many Montanans driving trucks and SUVs, this could be a meaningful benefit for eligible buyers.

There’s also a temporary tax break on up to $25,000 in tip income. If you work in Bozeman’s hospitality, restaurant, or service industry—where tipped roles are common—this is one worth watching as final details roll out.

The SALT deduction cap has increased to $40,000. While Montana isn’t a high-tax state compared to others, this may matter for residents with property elsewhere or those with higher income levels. Note that the benefit phases out for certain high‑income earners.

Wealth Transfer, Investment & Retiree Provisions

If you’re over a certain age, you may qualify for the temporary $6,000 “Senior Bonus” deduction—an added benefit for eligible older adults across Big Sky Country.

Estate, gift, and generation-skipping transfer tax exemptions have been permanently raised to $15 million. This may offer expanded opportunities for long‑term wealth and estate planning, especially for Bozeman‑area families with farms, ranches, or appreciable real estate holdings.

Capital gains brackets will now be adjusted for inflation, potentially helping Montana investors stay within more favorable tax ranges depending on their portfolio income.

The Alternative Minimum Tax (AMT) relief has been made permanent. However, higher-income earners may still see faster phaseouts of certain benefits.

Other Noteworthy Changes

Medicaid is undergoing major shifts—including funding cuts, new work or volunteer requirements, and tighter eligibility rules. These changes may impact Montanans who rely on the program for healthcare access.

A new savings tool—“Trump Accounts”—has been created for eligible children. These accounts offer tax‑advantaged growth, set contribution limits, and structured investment options designed to help families plan for the future.

Clean energy and electric vehicle credits are being phased out. If you're considering energy‑efficient upgrades for your Bozeman home or thinking about purchasing an EV, acting sooner may help you take advantage of the remaining incentives.

Preparing for What’s Ahead in Montana

The OBBBA affects a wide range of taxpayers—from service workers and young families to ranch owners, retirees, and high‑net‑worth individuals across the Bozeman region. With so many changes to keep track of, it’s important not to wait until tax season to understand how these provisions may affect your financial picture.

This is an ideal time to review your tax strategy and long‑term financial plan. Working with a trusted financial advisor or tax professional can help you navigate both the permanent and temporary rules and determine what adjustments may be right for you and your family.

As always, we’re here in Bozeman to help you think through the numbers, weigh your options, and build a strategy that supports your long‑term goals.
