2 Important Changes for Businesses under the New Tax Law

Sarah B

The One Big Beautiful Bill Act (OBBBA) introduces a range of tax changes that will impact businesses. Many provisions set to expire this year are now being extended or made permanent. Below is a snapshot of two important changes to help you with tax planning in the fourth quarter of 2025 and going forward.


How the Deduction for R&E Expenses Has Changed

Under the Tax Cuts and Jobs Act (TCJA), businesses had to amortize deductions for Section 174 research and experimentation (R&E) costs over five years for expenses incurred in the United States or 15 years for those incurred abroad. This provision used a mid-year rule that effectively stretched write-offs over six years. The OBBBA changes that by permanently allowing full, immediate deductions for domestic R&E expenses starting in the 2025 tax year. Foreign R&E expenses will still be amortized over 15 years.


In addition, the OBBBA lets “small businesses” (in 2025, those with average annual gross receipts of $31 million or less for the past three years) claim R&E deductions retroactively to 2022. A business of any size with domestic R&E costs from 2022 to 2024 can choose to speed up the remaining deductions for those years over a one- or two-year period.


How the Business Interest Deduction Has Changed

Generally, the TCJA limited business interest deductions to 30% of the taxpayer’s adjusted taxable income (ATI) for the year. Before the OBBBA, ATI generally referred to earnings before interest and taxes. For tax years beginning after December 31, 2024, the OBBBA increases the cap on the business interest deduction by excluding depreciation, amortization and depletion when calculating ATI. This change typically increases ATI, allowing taxpayers to deduct more business interest expense.

But it’s important to note that, in 2025, taxpayers with average annual gross receipts for the last three years that don’t exceed $31 million are exempt from the interest deduction limitation.


Rethink Tax Planning

For business owners, the OBBBA helps resolve tax planning uncertainty. Keep in mind, these are just two of the key changes for businesses in this tax legislation.

Employers seeking to offer family-friendly benefits may want to consider flexible spending accounts (FSAs) for dependent care. These FSAs let employees make pre-tax contributions through payroll withholding to help cover eligible expenses. Because of the major tax bill enacted on July 4, 2025, the annual contribution limit, currently $5,000, will rise to $7,500 in 2026. FSA contributions reduce employees’ income tax and payroll tax and employers’ payroll tax. Withdrawals used to pay qualified expenses are tax-free. These include expenses for care for a child under age 13 or another dependent unable to care for themselves due to physical or mental limitations. Contact the office with questions.
