House Republicans’ Fiscal Year 2025 Budget Resolution, passed on February 25, 2025, is shaking up the tax world with a $4.5 trillion tax-cut blueprint. A key target? Eliminating Section 174 amortization—a rule forcing businesses to spread R&D deductions over five years (15 for foreign costs) since 2022. As of March 05, 2025, this move could unlock immediate expensing and supercharge Section 41 R&D tax credits. Here’s the latest on how it might kill Section 174 amortization, when it could happen, whether it’ll be retroactive, and how businesses stand to gain—backed by hard numbers.
The Current Push: FY 2025 Budget Resolution in Focus
The House Budget Committee’s FY 2025 plan, cleared the House with a razor-thin 218-215 vote, per AP News. It’s a reconciliation bill, meaning it can dodge a Senate filibuster with just 51 votes—crucial with the GOP’s 53-47 Senate edge as of now. The resolution directs the Ways and Means Committee to slash revenue by $4.5 trillion over 10 years, a figure that insiders say includes restoring full R&D expensing. This aligns with President Trump’s tax agenda, which AP News reports aims to extend the 2017 Tax Cuts and Jobs Act (TCJA) and fix provisions like Section 174 that hit businesses hard.
Since 2022, companies have amortized $100 billion in annual U.S. R&D spending (based on National Science Foundation estimates), reducing immediate deductions to roughly $20 billion yearly. The FY 2025 plan could reverse that, letting firms deduct the full $100 billion upfront—a $80 billion annual swing in tax relief before credits.
When Will Section 174 Amortization End?
The timeline is tight but moving fast. House Speaker Mike Johnson, per AP News, wants a full reconciliation bill passed by April 2025—roughly 60 days from now. Committee drafting is already underway, with the Ways and Means Committee tasked to finalize tax details by mid-spring. Senate alignment, balancing border security priorities with the House’s $4.5 trillion cuts, could stretch this to June or July 2025. If all goes smoothly, Trump could sign it by August 2025, though GOP infighting or the $2 trillion in proposed spending cuts (e.g., Medicaid reductions) might push it to late 2025.
Historically, reconciliation bills like the TCJA took 6-9 months from resolution to law. With the FY 2025 resolution already passed, businesses could see Section 174 amortization gone within 5-9 months—potentially as early as August 2025 or as late as December 2025.

Retroactive Relief: A $200 Billion Question
Will the Bill revert full R&D expensing retroactively to 2022, when Section 174 amortization began? The budget resolution doesn’t say, and the legislative text is silent. Since 2022, firms have amortized roughly $300 billion in R&D costs over two tax years (NSF data), locking $240 billion into future deductions. A retroactive repeal could free that $240 billion for immediate expensing, letting companies amend 2022-2024 returns and claim refunds.
The catch: retroactivity spikes costs. Adding $240 billion to the $4.5 trillion package could strain the GOP’s fiscal math, especially with $2 trillion in offsets already debated. The TCJA’s major changes were prospective, starting in 2018, suggesting a January 2026 effective date is more likely. Still, business lobbying—citing $50 billion in lost cash flow annually—might sway lawmakers for a 2022 rollback. It’s a 50-50 shot as of now.
How Reverting Section 174 Boosts Section 41 R&D Credits
Eliminating amortization directly benefits users of the Section 41 R&D tax credit, which offsets 20% of qualified research expenses (QREs) above a base. Estimate your R&D Tax Credit savings in a couple of minutes. Here’s the payoff with numbers:
- Bigger Deductions, Bigger Credits: A firm spending $10 million on R&D in 2025 currently deducts $1 million in the first year under amortization rules, yielding a $210,000 tax savings (at 21%) and a $600,000 Section 41 credit (based on $8 million in QREs above a $5 million base, simplified). This totals an $810,000 tax benefit today. With full expensing, the deduction jumps to $10 million, generating a $2.1 million tax savings, paired with the same $600,000 credit—a $2.7 million tax benefit in all.
- Cash Flow Surge: The IRS estimates 20,000 businesses claim a total of $20 billion in Section 41 credits yearly. Ending amortization could boost that to $30 billion annually, with immediate expensing adding $80 billion in deductions—totaling $110 billion in tax relief vs. $40 billion now.
- Retroactive Windfall: If retroactive, amending 2022-2024 returns could yield $6 billion in extra credits and $240 billion in deductions—a $50 billion cash infusion for R&D firms over three years.
- Growth Fuel: Tech and manufacturing, claiming 70% of credits (IRS data), could reinvest savings, potentially adding 50,000 jobs annually (per industry studies).
What Businesses Should Do Now
As of March 05, 2025, the end of Section 174 amortization is plausible but not locked in. Monitor the Ways and Means Committee’s work this Spring—draft text could drop by May 2025. Prep for two scenarios: a 2026 start (plan cash flow accordingly) or a 2022 retroactive win (audit past returns and prepare to amend). Either way, the $4.5 trillion tax cut, if passed, could hand R&D-driven businesses a $100 billion-plus lifeline. Stay tuned—April 2025 is the next big checkpoint.
