What Is the Section 174 Amortization Fix?
The Section 174 amortization fix refers to proposed or enacted legislative changes to reverse a controversial tax policy change that took effect in 2022, requiring businesses to amortize, rather than immediately deduct, their research and experimental (R&E) expenditures over five years (15 years for foreign research). Prior to 2022, Section 174 of the Internal Revenue Code allowed companies to fully deduct R&E costs in the year they were incurred. The shift to mandatory amortization significantly increased taxable income for many U.S. businesses and reduced the immediate financial benefit of investing in innovation. The “fix” refers to bipartisan legislative efforts to restore the original expensing treatment; either retroactively, prospectively, or both; giving businesses the ability to once again deduct qualifying R&D costs in the year they occur.
Why This Change Matters, and Why It Happened
The mandatory amortization requirement was not a stand-alone policy decision. It was a revenue offset built into the Tax Cuts and Jobs Act of 2017 (TCJA), a delayed provision designed to help pay for other tax cuts by deferring R&D deductions into future years.
For many businesses, especially manufacturers, software developers, and engineering firms, the real-world impact was significant. Companies that had long planned their tax positions around immediate R&D expensing suddenly found themselves carrying higher tax burdens, even when their underlying business activity had not changed. In some cases, companies were taxed on income that did not reflect their actual economic position, paying taxes on dollars that were simultaneously being reinvested into innovation.
The practical result: reduced cash flow, more complex tax planning, and in some cases, a chilling effect on domestic R&D investment.
What a Fix Would Restore
If Congress passes a retroactive fix, which has been a central feature of most proposals, the restoration would allow businesses to:
- Immediately deduct qualifying R&E expenditures in the year incurred, rather than spreading them across five or 15 years
- Potentially file amended returns or claims for refund for tax years affected by the amortization requirement
- Align their tax treatment of R&D costs with the economic reality of how those costs are actually incurred
For businesses with significant R&D activity, the financial impact of a retroactive fix could be substantial, potentially unlocking meaningful cash refunds and reducing future tax liability.
How This Intersects with the R&D Tax Credit
It is important to understand that Section 174 and the R&D Tax Credit under Section 41 are related but distinct. Section 174 governs the deductibility of research and experimental expenditures. Section 41 provides a credit against tax liability based on qualifying research activities.
Under current law, expenses must first qualify as Section 174 R&E expenditures before they can be considered for the Section 41 R&D Tax Credit. The two provisions work in tandem, and changes to Section 174 treatment can directly affect how companies plan and document their R&D credit positions.
For this reason, any legislative fix to Section 174 is not just a deduction story. It has cascading implications for R&D credit planning, documentation strategy, and overall tax positioning.
What Businesses Should Be Doing Now
Whether or not a legislative fix has been enacted by the time you are reading this, R&D-active businesses should be taking a proactive posture:
- Maintain detailed documentation of all qualifying research and experimental activities and expenditures, regardless of how they are ultimately treated
- Assess the magnitude of exposure created by the amortization requirement across affected tax years
- Work with qualified R&D tax specialists to evaluate amended return opportunities and model the impact of various legislative scenarios
- Avoid assuming the status quo: the legislative landscape around Section 174 has remained fluid, and businesses that have positioned themselves conservatively may be well-positioned to act quickly when a fix is enacted
The firms best positioned to benefit from any legislative change are those that have already done the foundational work: accurate identification of qualifying expenditures, clean documentation, and a clear understanding of their credit-eligible activity.

Frequently Asked Questions
Q: What is Section 174? Section 174 of the Internal Revenue Code governs the tax treatment of research and experimental (R&E) expenditures. Prior to 2022, businesses could deduct these costs immediately in the year incurred. Starting in 2022, businesses were required to amortize them over five years (15 years for foreign research).
Q: What does “fix” mean in the context of Section 174? A “fix” refers to legislation that would restore immediate expensing of R&E costs — reversing the amortization requirement that took effect in 2022. Most proposed fixes have included retroactive relief, meaning businesses could potentially recover taxes paid under the amortization rules.
Q: How is Section 174 different from the R&D Tax Credit? Section 174 governs whether and when R&E expenditures can be deducted. The R&D Tax Credit under Section 41 provides a credit against taxes owed for qualifying research activities. The two provisions are related — qualifying under Section 174 is a prerequisite for the R&D Tax Credit — but they function differently and have different financial impacts.
Q: Does a Section 174 fix eliminate the need for the R&D Tax Credit? No. Even with restored expensing under Section 174, the R&D Tax Credit under Section 41 remains a separate and valuable opportunity. Many businesses pursue both strategies in tandem to maximize their overall tax position.
Q: What should my business do while waiting for a legislative fix? Continue documenting R&D activities thoroughly, assess how many tax years have been affected by the amortization requirement, and work with a qualified R&D tax specialist to understand your exposure and model your options. Proactive preparation now means faster action when a fix is enacted.
