The One Big Beautiful Bill (“OB3”) takes a dual approach to business taxes: enhanced deductions for business investments paired with stricter limits on loss deductions. OB3 introduces expanded bonus depreciation and doubled Section 179 limits for equipment and property purchases, while also implementing permanent caps on excess business losses and modifying interest deduction calculations.
Part 2 of our blog series on OB3 focuses on business investment and loss limitation provisions:
1. Bonus Depreciation for Qualified Property
Bonus depreciation has been reinstated for certain new qualified property—including equipment, vehicles, and software—acquired after January 19, 2025. At the federal level, businesses may deduct up to 100% of the cost of qualifying property in the year of acquisition. However, Minnesota does not conform to this federal provision, so the full cost may not be deductible on your Minnesota return.
2. Expensing Limits under IRC Section 179
Section 179 allows businesses to expense personal property and certain qualified real property up to a set limit. OB3 increased the maximum deduction limit from $1 million to $2.5 million. Additionally, the phase-out threshold was increased from $2.5 million to $4 million. These limits will be adjusted for inflation. This applies to property placed in service in taxable years beginning after December 31, 2024.
3. Business Interest Deduction Limitation
IRC Section 163(j), beginning after January 1, 2022, limited interest deductions to 30% of taxable EBIT (Earnings Before Interest and Taxes) for certain businesses. OB3 modifies this limitation by reverting the calculation from Taxable EBIT back to taxable EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) for tax years beginning after December 31, 2024, which will allow more interest to be deducted. For tax years beginning after December 31, 2025, OB3 makes additional changes, including modifying the definition of interest included in the calculation. The revised provision will require taxpayers to include all interest, even capitalized amounts, in the total interest amount when determining the interest limit.
4. Excess Business Losses
The Tax Cuts and Jobs Act (“TCJA”) limited the deductibility of excess business losses for noncorporate taxpayers (including individuals who own a business, trusts, and estates), a limitation that was set to expire in 2028. OB3 made this limitation permanent. An excess business loss is the amount by which the total deductions attributable to all of a noncorporate taxpayer’s trades or businesses exceed their total gross income and gains attributable to those trades or businesses. In other words, if your business losses exceed your business profits by more than a certain limit ($626,000 for married filing jointly or $313,000 for singles in 2025), the excess loss beyond that limit is treated as excess business loss. Any disallowed losses carried over to the next tax year will be treated as net operating losses rather than excess business losses.
Conclusion
OB3’s business provisions create new opportunities for investment-focused deductions while establishing permanent limitations on business loss utilization. These changes will require business owners to adjust their tax planning strategies to navigate the updated depreciation benefits, Section 179 limits, and loss restriction rules as they plan for 2025 and beyond. However, these changes also come with compliance complexities and qualifying criteria that require careful navigation. We encourage you to meet with your CPA or tax advisor to discuss planning strategies that work best for your specific situation.
