The One Big Beautiful Bill: What Small Business Owners Need to Know About 2025 Tax Changes

ByReinspired Books

In 2025, small business taxes are undergoing one of the biggest overhauls in years. The newly passed One Big Beautiful Bill (OBBB) includes major updates designed to simplify tax rules, boost investment incentives, and reduce the tax burden on small businesses and individuals. These changes aim to support growth, streamline deductions, and make tax planning easier for business owners. You can review the full legislative text on Congress.gov.

Full Expensing Becomes a Permanent Feature of Small Business Taxes

For businesses investing in property and equipment, the OBBB makes 100% first-year expensing permanent. You can now immediately deduct the full cost of qualified business property in the year it’s placed in service.

Why this matters for small business taxes: Faster deductions = improved cash flow = smarter reinvestment in your business.

Bonus Depreciation

While the bill restores 100% bonus depreciation, it only applies to property acquired after January 19, 2025. Property acquired before that will still follow the previous phase-down schedule (like 40% depreciation in 2025). Unfortunately, the bill does not allow amended returns to retroactively apply the new rules.

Real Property Expensing Expands to Support Production Businesses

New Section 168(n) allows nonresidential real estate used in manufacturing or refining to qualify for 100% bonus depreciation. Traditionally, real estate didn’t qualify under bonus depreciation rules—this is a major shift.

This change to small business tax law is especially beneficial for production-based industries investing in physical infrastructure.

Section 179 Deduction Limits Get a Big Boost

One of the most-used tools in small business taxes, the Section 179 deduction, is getting a major upgrade:

  • Deduction limit: $2.5 million
  • Phase-out threshold: $4 million
  • Full deduction phases out completely after $6.5 million in purchases

Plus, beginning in 2025, inflation adjustments will be based on the 2024 calendar year.

Corporate Charitable Deductions Have a New 1% Floor

If your business is a corporation, take note: charitable contributions now must exceed 1% of taxable income before you can deduct them. The 10% overall limit still applies, but you won’t get credit for the first 1%.

This impacts small business tax planning strategies for mission-driven companies and those that regularly donate.

Domestic Research Gets Immediate Write-Offs

Under new Section 174A, domestic research and experimental (R&E) expenses can now be fully deducted in the year incurred. Foreign R&E remains amortized over 15 years.

This change is a big win for small businesses in innovation-heavy fields, such as product development, technology, and engineering.

Beginning in 2026, small businesses will only need to issue 1099s for payments totaling more than $2,000 per year — up from $600.

QBI-Deduction Becomes More Accessible

Section 199A just got more generous:

  • Expanded phase-in limits: $75K (single) / $150K (joint filers)
  • New guaranteed minimum deduction: $400 for businesses with at least $1,000 in qualified business income (QBI) and material participation

Why this matters: More entrepreneurs—especially small service providers—can now benefit from the QBI deduction, even if income is modest.

🧾 Additional Provisions to Watch

We’ll explore these in future posts:

  • Targeted expansion of the business meals deduction after prior limitations tightened in 2017
  • Green energy tax credits are being revised and expanded
  • Excess business loss (EBL) limitation has been extended
  • Paid Family and Medical Leave (PFML) credit is growing
  • Employer-provided child care tax credit has been enhanced

Final Thoughts on 2025 Small Business Taxes

The OBBB impacts nearly every aspect of small business taxes. Whether you’re purchasing new equipment, expanding real estate, funding R&D, or reviewing your deduction strategy, these changes create opportunities—but also require planning.

Now is the time to:
