How the Big Beautiful Bill Reshapes R&D Tax Credit Treatment for 2025 and Beyond

On July 4, 2025, President Trump signed the Big Beautiful Bill (BBB) into law. While most headlines focused on the rollback of clean energy incentives, the bill delivered a quiet but significant win for businesses investing in innovation.

With improved expensing rules and refund opportunities for small businesses, the BBB represents one of the most favorable updates to R&D tax treatment in recent years. Here’s what changed—and how your business can benefit.

Before the BBB: The Strain of Section 174

Since 2022, domestic R&D costs have been subject to mandatory capitalization and five-year amortization under Section 174. That meant even pre-revenue startups had to defer deductions, putting pressure on cash flow and complicating tax planning. Foreign R&D is even more restrictive, requiring 15-year amortization.

While the R&D tax credit remained available, it often didn’t fully offset the burden created by delayed deductions—especially for small or early-stage companies.

What the BBB Changes for R&D

The BBB brings relief on multiple fronts, especially for companies engaged in U.S.-based research and development.

1. Immediate Expensing Returns

For tax years beginning after December 31, 2024, businesses now have a choice:

• Immediately deduct domestic R&D expenses in the year incurred
• Or, capitalize and amortize those domestic R&D expenses over their useful life (minimum 60 months)

This added flexibility allows companies to manage taxable income more strategically. It also helps restore some of the pre-2022 simplicity that was lost when full expensing was eliminated.

Note: The treatment of foreign R&D remains unchanged—still amortized over 15 years.

2. Retroactive Relief for Small Businesses

The bill also allows a special refund opportunity for “Small Business Taxpayers,” defined as those with average annual gross receipts of $31 million or less.

These companies can:

• File amended returns to immediately deduct 2022-2024 capitalized R&D costs and claim refunds for taxes paid under the old amortization rules, or
• Accelerate the deduction of remaining unamortized 2022-2024 domestic R&D costs over one or two years, beginning with tax year 2025.

This retroactive fix could result in immediate cash refunds for eligible businesses—and help recover value that would otherwise be spread over multiple years.

3. Partial Relief for Larger Companies

For businesses above the $31M threshold, there’s no retroactive refund path—but there is a faster deduction schedule. They’ll now be able to deduct remaining unamortized 2022–2024 R&D expenses over one or two years, beginning in 2025.

What This Means for You

If you’re a startup or small business, this bill presents both immediate and future opportunities. You can recover past costs, reduce your current tax liability, and continue to leverage credits going forward.

Larger companies may not see direct refunds, but they’ll benefit from faster deductions, creating stronger tax positioning over the next few years.

Whether you’re building new technology, improving internal systems, or solving technical problems for clients, it’s time to re-evaluate your R&D strategy.

Next Steps

To take advantage of the BBB’s updates:

1. Review your prior tax filings to identify any capitalized R&D from 2022–2024.
2. Confirm whether you qualify as a Small Business Taxpayer under the $31M threshold.
3. Talk to your CPA about filing amended returns or deducting remaining unamortized 2022-2024 R&D expenses in 2025/2026.
4. Plan for 2025 and beyond using the new expensing options now available.

Conclusion

The Big Beautiful Bill gives R&D-heavy businesses more flexibility, more clarity, and more cash flow potential. With immediate expensing back on the table and refund options for small businesses, this is one of the most business-friendly updates in recent tax history.
