What Is an R&D Tax Credit Study?
An R&D tax credit study is a structured, detailed analysis of your company’s projects, costs, and documentation designed to quantify and substantiate the federal research credit under Internal Revenue Code Section 41. This study aligns the credit calculation with research and experimental deduction rules under Sections 174 and 174A, particularly critical under post-OBBBA rules effective through 2026.
A modern study is not just a calculation spreadsheet. It’s a defensible narrative plus data built to withstand IRS scrutiny. The R&D tax credit is activity-based and not industry-specific, allowing any company to qualify if their work meets specific IRS criteria. Eligible costs can include wages, supplies, contractor fees, and cloud computing fees for development and testing. Domestic expenses related to qualifying research may also be included.
Typical users include technology companies, manufacturers, life sciences firms, software and SaaS businesses, engineering firms, and startups with limited revenue but intensive development activities. In 2019, $656 billion was spent on R&D in the United States, highlighting the significant investment the credit aims to support.
Main outputs of a study include:
- Qualified research narrative by business component
- QRE (qualified research expense) schedules
- Methodology memo
- Audit-ready documentation file
Current Law: Section 41 Credit and Section 174/174A Rules (2022–2026)
The R&D credit under Section 41 interacts directly with research deduction rules under Sections 174 and 174A. The R&D Tax Credit was originally enacted in 1981 to stimulate domestic innovation and was made permanent by the Protecting Americans from Tax Hikes Act of 2015.
For taxable years beginning on or after January 1, 2022, Section 174 requires that foreign R&E expenditures be capitalized and amortized ratably over a 15-year period. However, on July 4, 2025, the One Big Beautiful Bill Act reinstated and made permanent immediate expensing for domestic R&E expenditures under Section 174A. The OBBBA allows taxpayers to deduct any remaining unamortized domestic R&E costs entirely in 2025 or over a two-year period.
Section 280C(c) coordination remains essential: taxpayers must either reduce the Section 174A deduction or elect a reduced credit. Your study must model both outcomes to maximize tax benefits. IRS Form 6765 reporting, especially new Section G disclosures, becomes mandatory for most filers for tax year 2026, so studies completed now must anticipate these requirements.
What Qualifies: Activities and Expenses to Capture in an R&D Tax Credit Study
The Four-Part Test for qualifying R&D activities under Section 41 includes:
- Permitted Purpose – Intended to develop or improve functionality, quality, reliability, or performance
- Technological in Nature – Fundamentally rely on engineering, physics, chemistry, or computer science
- Elimination of Uncertainty – Must eliminate technical uncertainty regarding capability, method, or design
- Process of Experimentation – Involves systematic trial and error, modeling, or simulation
Research and development tax credits are available to all organizations that engage in activities to develop new or improved products, processes, or techniques, as broadened by the Protecting Americans from Tax Hikes Act of 2015. Research activities must be conducted within the United States to qualify.
Qualifying activities include:
- New or improved product development
- Process optimization on a manufacturing line
- Developing internal-use or customer-facing software
- Prototyping and testing with iterative design
Non-qualifying activities:
- Cosmetic design changes without functional improvement
- Market research and data entry
- Routine quality control
- Reverse engineering without innovation
The IRS defines qualified research expenses as the sum of in-house research expenses and contract research expenses. To qualify, at least 80% of an employee’s services must be related to qualified research activities for their wages to be considered qualifying expenses. Supply costs consumed in experimentation and 65% of payments to third-party contractors also qualify. Employee salaries associated with qualified research activities may also be included in qualifying costs.
Methodology: How to Perform an R&D Tax Credit Study in 2026
This is the practical core for readers needing to act quickly.
Step 1: Scoping and Eligibility Assessment Review 2022–2026 financials and organizational charts. Identify R&D-heavy cost centers and determine whether the regular or alternative simplified credit method is more favorable.
Step 2: Project Identification Use development roadmaps, engineering tickets, Jira boards, or manufacturing change orders from 2023–2025 to build a defensible project list tied to specific business components. Identify each existing business component where qualifying research activities occurred.
Step 3: Technical Interviews Schedule structured interviews with engineers, scientists, and product managers to discover information about uncertainties, experiments, and technological bases. Interview notes become part of your study file.
Step 4: Quantifying QREs Tie payroll data to time allocations by project. Flag employees meeting the 80% rule for full inclusion. Use timesheets, sprint reports, or reasonable estimating methodologies.
Step 5: Credit Calculation Businesses can claim the R&D Credit by filing IRS Form 6765, which requires identifying qualifying expenditures and providing adequate documentation. The Alternative Simplified Credit provides a credit equal to 14% of qualified expenses exceeding 50% of the average QREs from the previous three years. The R&D tax credit typically provides a direct cash savings of 6% to 10% of qualified spending, offering a dollar-for-dollar reduction in federal income tax liability.
Step 6: Documentation Describe your methodology in a formal memo detailing sampling strategies and allocation assumptions, making the study reproducible for IRS review.
Documentation & Audit Readiness for Your R&D Tax Credit Study
With expanded Form 6765 disclosures mandatory for 2026 returns, contemporaneous documentation is central to credit support. QREs must be incurred in connection with the taxpayer’s trade or business.
Key documents to compile:
- Project descriptions and technical design specs
- Test plans, results, and failure analyses
- Sprint backlogs and lab notebooks
- Patent filings and change orders
Financial support needed:
- General ledger extracts for R&D accounts
- Payroll registers with job codes
- Vendor invoices for supplies and testing labs
- Contracts for third-party research
Create a clearly organized electronic audit file by tax year and business component to respond quickly to IRS Information Document Requests and demonstrate the ability to support the claim.
Common Pitfalls in R&D Tax Credit Studies (and How to Avoid Them)
Many IRS disputes stem from weak methodology or missing documentation rather than ineligibility. The R&D credit is historically more effective at promoting incremental innovation rather than radical breakthroughs, so ensure your claims reflect realistic development activities and are properly supported under the four-part test.
Common errors:
- Including non-technical staff without support
- Counting routine bug fixes as qualified projects
- Double-counting foreign R&D still subject to amortization
- Unsupported percentage allocations
Funded research presents particular risk. Grants, customer contracts, and cost-sharing arrangements can reduce eligible QREs if the taxpayer lacks financial risk or rights to results. Many states offer their own incentives with different definitions, so map federal expenses to state programs where you operate.
FAQ: Practical Questions About R&D Tax Credit Studies
Who should consider commissioning a study in 2025–2026?
Companies in tech, manufacturing, biotech, SaaS, engineering, and startups with intensive development work. Small firms and SMEs are often more responsive to tax credits because they are typically more cash constrained.
How far back can we amend claims?
Businesses can claim missed R&D tax credits retroactively by amending prior-year tax returns, generally up to three years back. For calendar-year corporate filers, 2022 returns remain amendable until approximately March 15, 2026. These are commonly referred to as open tax years.
Can startups with little tax liability benefit?
Yes. Qualified small businesses can use up to $500,000 annually of the R&D tax credit to offset the employer portion of Social Security and Medicare payroll taxes.
What happens to unused credits?
Unused R&D tax credits can often be carried forward for up to 20 years under the internal revenue code, preserving their value during lean periods.
How long does a typical study take?
For mid-size companies, expect 6–12 weeks depending on complexity and data quality.
