Working Families Tax Cut Act Signed Into Law, Extending Key Deductions for Montana SMBs

WASHINGTON – A sweeping federal tax package known as the Working Family Tax Cuts was signed into law on July 4, following its passage in the House of Representatives on July 3. The legislation, also referred to by supporters as the One Big Beautiful Bill (OBBB), delivers significant changes for Montana’s small and mid-sized businesses by making key provisions of the 2017 Tax Cuts and Jobs Act (TCJA) permanent and introducing new incentives. For Montana’s business community, one of the most impactful elements of the new law is the extension of the Section 199A small business tax deduction. According to an announcement from Representative Ryan Zinke’s office, this provision is expected to benefit approximately 29,000 Montana firms, which constitutes nearly 45% of all businesses in the state. The law also restores full, immediate expensing for domestic research and development costs, a change praised by business leaders for freeing up cash flow. During an April 15, 2026, hearing before the U.S. House Committee on Small Business, Traci Tapani, Co-President of Wyoming Machine, Inc., testified that the permanence of key provisions gives owners the certainty needed for long-term investment. Similarly, Natalie Kaddas, CEO of Kaddas Enterprises in Utah, noted that the previous requirement to amortize R&D costs had tied up capital and increased her company's estimated tax liability by 35%. The restoration of immediate expensing is seen as critical for maintaining a competitive advantage. The law also makes the Opportunity Zone program permanent. Montana has 25 designated Opportunity Zones, which have been credited with creating 3,000 jobs and 500 new housing units. By solidifying the program, the legislation aims to encourage continued investment in these economically distressed communities. Additionally, the bill includes targeted incentives to support Montana’s manufacturing sector, an industry that accounts for 5% of the state's total employment. Proponents argue the legislation will prevent a substantial tax increase that was looming for both individuals and businesses. According to analysis from the Flathead Beacon, the law spares the average Montana family from a $2,500 annual tax hike and prevents a nearly $1,200 increase for the state's small businesses. Supporters also project that the tax cuts will lead to significant wage growth in Montana, with inflation-adjusted wages expected to rise by $3,400 to $6,100 over the next four years. "From protecting Montana jobs to increasing take-home pay and supporting small businesses, the One Big Beautiful Bill will deliver real results for Montana," Rep. Zinke stated in a press release. "This bill not only prevented the largest tax hike in American history but expanded tax relief for Social Security recipients, overtime earners, and tipped service industry workers." Beyond direct tax provisions, the law contains measures aimed at boosting domestic energy production by reducing regulatory hurdles and opening more federal lands and offshore areas to oil and natural gas leases. The bill also allocates resources to enhance border security with the stated goal of combating the flow of illicit drugs like fentanyl. The federal action complements a broader push for tax reduction at the state level. Montana Governor Greg Gianforte has championed a state budget that lowers the income tax rate most residents pay from 6.5% to 5.9% and expands the business equipment tax exemption from $300,000 to $1 million. This state-level reform is estimated to eliminate the business equipment tax for over 5,000 small businesses, farms, and ranches. While the extension of popular provisions like the 199A deduction and immediate R&D expensing offers clear benefits, the interplay of new federal law with Montana's evolving state tax code introduces significant complexity for business owners. Our experience shows that translating legislative changes into tangible bottom-line savings requires careful, proactive planning. Many businesses fail to fully capitalize on incentives like Opportunity Zones or manufacturing credits simply because they are unaware of the specific documentation and strategic decisions required to qualify. A comprehensive review of a company's financial structure and operations is essential to align with the new rules and maximize after-tax income. For businesses navigating these updates, professional guidance on tax preparation and compliance is not a luxury but a necessity for ensuring every available deduction is claimed correctly.
