Section 174 R&D Capitalization and Section 174A: 2026 CPA Guide

Section 174 planning did not disappear; it changed. Software companies still need to reconcile 2022-2024 specified research expenditure capitalization, current domestic research deduction rules, foreign research cost recovery, Section 41 credit support, and Section 280C reductions before the tax return is filed.

What Still Needs to Be Modeled

For 2022-2024 tax years, many taxpayers had to capitalize and amortize specified research and experimental expenditures rather than deducting them currently. Those legacy positions can still affect amended returns, method changes, deferred taxes, and credit support.

For 2026 planning, IRS Form 6765 instructions now reference Section 174A for domestic research or experimental expenditures and explain that taxpayers who do not elect the reduced Section 280C credit generally must reduce domestic research or experimental expenditures otherwise deducted or capitalized by the amount of the research credit.

That means the planning question is no longer only "deduct or capitalize?" It is whether the R&D credit calculation, Section 280C election, domestic research deduction, foreign research treatment, and financial statement reporting all reconcile.

What Counts as SRE

The rule applies broadly to expenditures incurred in connection with the taxpayer's trade or business that represent research and development costs in the experimental or laboratory sense. The IRS expanded the scope to explicitly include:

• Software development costs — all of them, regardless of whether they would have been deductible under prior guidance.

• Wages, salaries, and benefits of personnel performing R&D activities.

• Cost of supplies and materials used in research.

• Contract research expenses (with limitations).

• Patent costs incurred in connection with R&D.

The inclusion of all software development was the bombshell. SaaS companies, app developers, fintech startups, AI labs, and gaming studios saw their primary expense category transformed from a current deduction into a five-year amortization.

Cash-Flow and Return-Position Impact

Legacy Section 174 capitalization could create taxable income even when the company had weak or negative operating cash flow. Current-year planning should still model cash tax, credits, net operating loss use, and deferred tax balances rather than treating R&D as a single-line deduction.

For startups and software companies, the practical question is whether engineering payroll, contractors, cloud costs, prototypes, and foreign development teams are classified consistently across the tax return, R&D credit study, and financial statements.

The R&D Tax Credit Interaction

The R&D tax credit under Section 41 remains available, and for many companies, it partially offsets the cash flow damage from Section 174. However, the credit is reduced for amounts capitalized — there is a basis adjustment requirement that prevents double-counting. The interaction is technical and requires careful coordination.

Foreign R&D Penalty

The 15-year amortization for foreign SRE expenditures is punitive — designed to discourage offshoring of R&D. Companies with development teams in India, Eastern Europe, Latin America, or Asia face a 15-year cost recovery for those wages. For a company spending $1M annually on offshore engineering, only about $33,000 is deductible in year 1.

2026 Planning: Section 174A, Section 41, and Section 280C

IRS Form 6765 now makes the coordination visible. A company that claims a research credit needs the QRE calculation, domestic research expense treatment, and Section 280C position to tell the same story.

For the IRS filing framework, see the Instructions for Form 6765, which address qualified research credits, payroll-tax elections, Section 174A references, and Section 280C coordination.

Foreign research costs, controlled-group allocations, and software development projects should be reviewed separately because the credit, deduction, and capitalization rules may not produce the same result for every cost pool.

What Companies Should Do Now

1. Document SRE expenditures rigorously by category, vendor, and geography. The split between domestic and foreign matters enormously.

2. Coordinate with the R&D tax credit study to optimize the interaction.

3. Model multi-year cash tax projections assuming both the current rule and any pending relief.

4. Consider Section 280C(c)(2) reduced credit election to avoid the basis reduction adjustment.

5. Refresh 2022-2024 positions for amended-return, method-change, or financial-statement implications.

Audit Implications for SEC Registrants

For audited companies, Section 174 capitalization creates significant deferred tax balances on the balance sheet. Auditors are scrutinizing:

• Identification of SRE costs and proper allocation.

• Domestic versus foreign classification.

• Coordination with R&D credit calculations.

• ASC 740 deferred tax assets and valuation allowance considerations.

• Proper disclosure in MD&A and the financial statement footnotes.

The Bottom Line

Section 174 and Section 174A planning is now a coordination exercise. R&D-heavy companies should align the credit study, domestic and foreign research cost treatment, Section 280C election, payroll-tax election, and financial reporting before filing.
