Tax Changes Set to Shape the U.S. Economy in 2026

Major tax changes approved under the “One Big Beautiful Bill Act” are expected to play a central role in shaping the U.S. economy in 2026. The measures affect both individuals and businesses, increasing disposable income for households and encouraging companies to invest more aggressively.

For individuals, the law makes permanent the lower income tax rates introduced in 2017, which were previously set to expire. Standard deductions are extended, while exemptions related to the alternative minimum tax are expanded. The estate tax exemption is also raised from $14 million to $15 million.

Several targeted tax breaks are designed to increase take-home pay. Up to $25,000 in tipped income will be exempt from taxation until 2029, although this benefit gradually phases out for those earning over $150,000 and excludes certain types of tips. Overtime pay receives similar treatment, with up to $12,500 exempted under the same conditions. Seniors aged 65 and over gain access to a new deduction of up to $6,000 through 2029.

Additional relief includes a tax deduction on interest paid on auto loans, capped at $10,000, provided the vehicle is assembled in the United States. The deduction for state and local taxes is also expanded, rising from $10,000 to $40,000 until 2029, a change that particularly benefits homeowners in high-tax states.

On the business side, the reforms focus heavily on boosting investment and productivity. Lower corporate tax rates from the 2017 reform are made permanent, providing long-term certainty for companies. Businesses are also allowed to fully expense certain equipment purchases immediately, reversing a gradual phase-out that began in 2023.

Research and development spending receives strong support, with full expensing allowed for U.S.-based R&D costs. Smaller businesses can even retroactively deduct qualifying expenses incurred since 2022. Tax specialists widely view these provisions as among the most effective tools for stimulating economic growth.

Limits on interest deductions are relaxed as well, expanding the calculation base to include amortization costs. Finally, owners of pass-through businesses, such as freelancers, family-owned firms, professional practices, and investment entities, can deduct up to 20% of their income. While opinions differ on the broader economic impact of this measure, it significantly lowers effective tax rates for many business owners.

Together, these changes are expected to inject additional liquidity into the economy in early 2026, through both higher paychecks and increased refunds, while encouraging businesses to invest and expand.
