I’m a Tax Expert: 5 Smart Moves To Prepare For Tax Changes Under Trump’s Big Beautiful Bill

The 'One Big Beautiful Bill' introduces significant, retroactive tax changes impacting various taxpayers, including new permanent deductions for tips, overtime, and an increased state and local tax (SALT) deduction cap, alongside a permanent 20% small-business deduction. Small businesses can also claim retroactive relief for R&D expenses under Section 174, while energy-efficient building and renewable energy projects face accelerated deadlines for full credit benefits. These provisions necessitate updated tax estimates and strategic planning to optimize benefits, though some high-income earners will see SALT deduction advantages phase out above a $500,000 adjusted gross income.

Analysis

The "One Big Beautiful Bill" (OBBB) introduces significant, retroactive tax provisions impacting various taxpayer segments. Key changes include new permanent deductions for tips and overtime pay, an increased State and Local Tax (SALT) deduction cap of $40,000 (inflation-adjusted), and the permanent reinstatement of the 20% small-business deduction. These measures aim to meaningfully reduce taxable income for eligible individuals and businesses, with some changes already active.

Small-business owners particularly benefit from the permanent 20% Qualified Business Income (QBI) deduction and the removal of limits on the pass-through entity tax (PTET) deduction. Businesses with under $31 million in receipts also gain retroactive relief under Section 174 for R&D expenses, offering refund claim opportunities for 2022 and 2023. Manufacturers are set to benefit from a permanent 100% bonus depreciation on new industrial facilities if construction is timed within qualifying windows.

The bill also incentivizes energy-efficient projects, urging taxpayers to accelerate qualifying 45L and 179D projects before June 30, 2026, and wind/solar projects by the end of 2027 for full benefits. While high-income taxpayers in high-tax states will see some relief from the increased SALT cap, these benefits begin to phase out once adjusted gross income (AGI) exceeds $500,000, indicating a targeted approach to tax relief.

Key Decisions for Investors

• Investors and businesses should immediately update 2026 tax estimates to incorporate new permanent deductions, such as for tips, overtime, and the 20% QBI deduction, to optimize withholding and avoid overpayments.
• High-income taxpayers in high-tax states should re-evaluate the benefits of itemizing deductions versus the standard deduction, considering the new $40,000 SALT cap and the AGI phase-out above $500,000.
• Companies involved in energy-efficient building or renewable energy projects should accelerate qualifying investments to meet critical deadlines (e.g., June 30, 2026, for 45L/179D; end of 2027 for wind/solar) to maximize available tax credits.
• Small business owners should actively pursue retroactive relief opportunities for 2022 and 2023 R&D expenses under Section 174 and leverage the permanent QBI deduction and increased PTET flexibility.
