Tax season is underway, and the 2026 filing year is shaping up to be one of the most consequential in recent memory for millions of Americans. Major tax law changes tied to the One Big Beautiful Bill Act are set to impact a wide range of taxpayers, including families, seniors, tipped workers, overtime earners, and individuals who purchased a new vehicle over the past year.

The new law introduces adjustments that could significantly alter how households prepare their returns, calculate deductions, and plan their finances. Families may see changes in how deductions apply to dependents and household expenses, while seniors could experience shifts in how retirement income and age-related benefits are treated. For tipped workers and those earning overtime, updated rules may affect how income is reported and what portions qualify for new or expanded deductions.

Car buyers are also among those affected, as the legislation includes provisions that change how certain vehicle-related expenses and credits are handled. These updates make documentation more important than ever, particularly for taxpayers who experienced major life or financial changes during the year.

ARC Seattle co-anchor Steve McCarron recently discussed the upcoming tax season with Mark Steber, Chief Tax Officer for Jackson Hewitt Tax Service, focusing on how taxpayers can best prepare. Steber emphasized the importance of organizing documents early, understanding eligibility for new deductions, and avoiding last-minute filing errors. He also highlighted the advantages of filing early, including faster refunds and more time to address potential issues.

As taxpayers navigate these changes, experts recommend reviewing income statements carefully, tracking qualifying expenses, and seeking professional guidance when needed. With the One Big Beautiful Bill Act reshaping key parts of the tax code, preparation and awareness will be critical to ensuring accuracy and maximizing potential benefits during the 2026 tax season.
