1. Consider a host of new business expense deductions
For business owners, the biggest changes coming from the OBBBA, signed into law on July 4, 2025, include a series of new or enhanced deductions for new equipment, structures, research and development and more, Navani says. For example:
Equipment purchases. Property acquired or placed in service on or after January 19, 2025 is now eligible for 100% expensing, known as the bonus depreciation deduction, up from 60% in 2024. “If you’re a manufacturer looking to expand a product line or a dentist in need of new chairs, and you’re looking for deductions in 2025, now could be a good time to move forward,” Navani says.
New structures. To promote manufacturing and production, the OBBBA allows for a full deduction for the costs of new factories and structures used for manufacturing. “Normally, if you’re putting up a building, it must be capitalized and depreciated over many years. Now, you can basically expense the whole thing,” Navani says. Construction must begin between January 20, 2025 and the end of 2028, with property placed in service before 2031. And no part of the structures can be used for offices or other non-manufacturing activities.
Research and Development (R&D). The OBBBA allows immediate deductions for domestic R&D expenses incurred from the start of 2025 moving forward. There’s a special provision enabling small businesses to expense R&D costs retroactively to 2022.
Among other new provisions, the OBBBA liberalizes business interest deduction rules, reinstating earnings before interest, taxes, depreciation, and amortization (EBITDA) when calculating interest that can be deducted in a taxable year. Another provision raises the limits on Section 179 expensing for certain depreciable business assets.
Each of these deductions is subject to complex rules and restrictions. And keep in mind that many states don’t follow federal fixed asset deduction rules, so your income for state tax purposes could be higher than income for federal purposes, Navani advises. Be sure to consult your tax advisor before taking action.
