Understanding Section 174:
The Critical Link Between R&D Tax Credit and Treatment of R&E Expenditures

Section 174 and the Research & Development (R&D) Tax Credit work in tandem within the U.S. tax code to help businesses to reduce their tax liability.
Section 174 is a provision of the Internal Revenue Code governing how businesses must treat their research and experimental (R&E) expenses like wages, supplies, and contract research payments for tax purposes. Building upon this foundation, the R&D Tax Credit (Section 41) offers powerful tax reductions for qualifying research activities.
Changes To Section 174 In Recent Years
The Tax Cuts and Jobs Act of 2017 fundamentally changed how businesses handle their research expenses, with these changes taking effect in 2022. Under the new framework, businesses must spread out (amortize) their research deductions over several years (5 years for domestic research and 15 years for foreign research). This marks a stark departure from the previous system where businesses could immediately deduct these expenses in the same tax year they were incurred.
While this law significantly altered the timing of research expense deductions, businesses can still benefit from both the modified Section 174 deductions and the R&D Tax Credit simultaneously.
Consider a technology company investing $100,000 in software development in 2024. Under Section 174, they must spread this deduction over five years, starting with $10,000 in 2024, followed by $20,000 in each of the next four years, with the remaining $10,000 in the final year.
However, this same $100,000 expense can simultaneously qualify for an immediate R&D Tax Credit. If we assume a 10% credit rate, this means an immediate $10,000 tax credit, directly reducing their tax liability in 2024.
While companies will wait to realize the full deduction benefit under Section 174, they can still receive immediate tax savings through the R&D Tax Credit.

Impact Of Changes To Section 174 On Businesses

The modifications to Section 174 have created ripple effects throughout the business community, particularly affecting companies heavily invested in research and development. Companies now face substantially increased tax burdens due to the inability to immediately deduct R&E expenses, leading to higher taxable income in the short term.
This impact is particularly pronounced in the technology and software sectors, where continuous innovation is fundamental to business operations. Small businesses and startups have been especially challenged by these changes, as they often operate with tighter cash flow margins.
The new requirements have also necessitated more sophisticated accounting systems and documentation processes, adding administrative complexity to an already demanding compliance landscape. Many businesses have had to restructure their R&D budgets and timing to accommodate these new tax implications.

Expected Changes To Section 174 - How To Prepare Your Business For The Future
The Section 174 landscape is set for a significant transformation in 2025. The new administration shows strong support for extending key provisions of the Tax Cuts and Jobs Act that would allow business to immediately deduct R&E expenses rather than amortizing over five years. However, businesses shouldn’t wait for these changes before acting.
With 2021 R&D credits approaching expiration this tax season and the potential for significant reductions in quarterly estimated tax payments, delaying your R&D Credit could result in missing out on valuable tax credits & deductions. The key is to balance current compliance requirements with preparation for anticipated changes, ensuring your business is ready to capitalize on tax benefits under both current and future scenarios.
Research Tax Credit — Elections Bring Relief On Amortization
Forward-thinking businesses should take immediate steps to position themselves for these changes while maximizing current benefits. This means implementing robust documentation systems, maintaining detailed records of research activities, and working with tax professionals to identify and document R&D activities. The key is to balance current compliance requirements with preparation for anticipated changes, ensuring your business is ready to capitalize on tax benefits under both current and future scenarios. Remember, waiting for the bill to pass could mean missing out on valuable tax credits and deductions that could immediately impact your bottom line.
