Research & Development Tax Credit FAQs

The R&D Tax Credit is a federal incentive that rewards U.S. companies for developing or improving products, processes, software, formulas, or technology. It provides a dollar-for-dollar reduction in tax liability — not just a deduction against income.

The credit is found in Internal Revenue Code §41 and has existed since 1981. The PATH Act of 2015 made it permanent and expanded access for startups and emerging growth companies.

Many U.S. states offer their own version of the credit on top of the federal benefit, which means the same qualifying activities can generate both federal and state savings.

Eligibility extends well beyond traditional research laboratories. Businesses across many industries qualify if they perform technical work that meets the IRS criteria.

Common qualifying industries include:

• Manufacturing & industrial automation
• Software & technology
• Construction & engineering
• Healthcare & medical devices
• Food science & processing
• Biotechnology & pharmaceuticals
• Energy & clean technology
• Aerospace & defense
• Specialty materials & chemicals

If your company improves products, automates processes, develops technical solutions, or addresses engineering challenges, you likely meet the basic requirements.

Activities that seek to improve function, performance, reliability, or efficiency may qualify. Common examples include:

• Developing new products or technical features
• Creating or improving software applications and systems
• Prototyping and iterative technical testing
• Improving manufacturing processes and production methods
• Experimenting with new materials, tooling, or automation systems
• Designing or refining technical specifications

The two key requirements are technical uncertainty at the start of the work and a systematic process of experimentation to resolve it. The activity does not have to succeed to qualify — failed projects can also count if they meet the criteria.

Per the IRS, all four requirements under IRC §41(d)(1) must be satisfied for an activity to count as qualified research:

• Section 174 Test — Costs must qualify as research and experimental expenditures incurred to eliminate uncertainty in developing or improving a product.
• Technological in Nature — Research must rely on principles of engineering, computer science, mathematics, or the physical or biological sciences.
• Permitted Purpose — Activities must intend to develop or improve the function, performance, reliability, or quality of a business component (product, process, software, technique, formula, or invention).
• Process of Experimentation — Research must involve a systematic process of evaluating alternatives through modeling, simulation, testing, or other methods to eliminate uncertainty.

If any one of these is missing, the activity does not qualify under §41 — even if it feels like "real" R&D in everyday language.

Yes, in many cases. Software development qualifies when it involves technical uncertainty and a systematic process of experimentation. Common qualifying activities include:

• Developing new applications, platforms, or APIs
• Building or improving algorithms, data models, or machine-learning systems
• Integrating disparate technical systems where the integration approach is uncertain
• Optimizing performance, scalability, or reliability of existing software
• Developing firmware, embedded software, or IoT systems

Routine maintenance, content updates, and bug fixes that do not involve technical uncertainty generally do not qualify. Internal-use software has additional requirements under the regulations.

Yes. Process improvements are one of the most commonly overlooked sources of qualifying activity. Examples include:

• Designing or refining production lines and tooling
• Reducing defect rates or improving yield
• Implementing or refining automation, robotics, or sensor systems
• Evaluating new materials or formulations
• Improving energy efficiency or throughput
• Developing custom machinery or fixtures

The work must involve technical uncertainty — meaning that at the start, your team did not know whether or how the improvement would succeed and had to experiment to find out.

Qualified Research Expenses (QREs) generally fall into three categories:

• W-2 Wages — Wages paid to employees for time spent performing, supervising, or directly supporting qualified research activities.
• Supplies — Tangible property (other than land or depreciable assets) consumed during research and experimentation.
• Contract Research — 65% of amounts paid to third parties for qualified research performed on the taxpayer's behalf.

Cloud computing expenses directly related to qualified research can also be included as supplies in many cases. Overhead and indirect expenses do not qualify as QREs under IRS guidance.

Each category has specific allocation and substantiation requirements — for example, wages must be tied to qualifying activities at the project or business component level, not just by job title or cost center.

There are two primary calculation methods, and taxpayers generally choose the one that produces the larger credit:

• Regular Credit — 20% of QREs above a fixed-base amount tied to historical research spending.
• Alternative Simplified Credit (ASC) — 14% of QREs above 50% of the average QREs from the prior three years (or 6% if there are no prior-year QREs).

The ASC is more commonly used because it requires less historical data. The credit typically ranges from 5%–15% of total qualified expenses depending on the calculation method, base period, and company-specific factors.

Taxpayers may also elect a reduced credit under §280C(c)(3) to avoid an add-back to taxable income — but this election must be made on a timely-filed original return.

Yes. More than 35 states offer their own R&D Tax Credit, and many use the same federal qualifying activities and expenses as the starting point. Some state credits are even more generous than the federal credit on a percentage basis.

State credits vary widely in:

• Credit rate and calculation methodology
• Refundability or transferability
• Carryforward periods
• Filing requirements and deadlines

A well-prepared federal study is generally the foundation for capturing both federal and state benefits. Our team identifies applicable state credits during the engagement.

Form 6765, "Credit for Increasing Research Activities," is the IRS form used to calculate and claim the R&D Tax Credit. It is filed with your federal income tax return (Form 1120 for C corporations, Form 1120-S for S corporations, Form 1065 for partnerships, or Form 1040 for sole proprietors).

The form has sections for:

• The regular credit calculation
• The Alternative Simplified Credit (ASC) calculation
• The §280C(c)(3) reduced credit election
• The qualified small business payroll tax election

We prepare complete Form 6765 documentation packages so your CPA can review and file the credit with confidence.

Yes. Most companies can amend the three prior open tax years to claim previously unclaimed R&D credits. Amended returns often produce immediate refunds or reductions of prior-year tax liabilities, which improves cash flow and effective tax rates.

Lookback claims have additional documentation requirements, particularly under recent IRS guidance (the 2022 §41 refund claim rules). The substantiation must be detailed enough to identify the business components, the activities, and the individuals involved.

Our team handles lookback engagements regularly and prepares documentation packages built to satisfy the heightened standard.

Most studies take 2–6 weeks to complete, depending on company size, project complexity, and documentation availability. Larger or multi-entity engagements can take longer.

Our process typically follows four stages:

• Discovery — Initial assessment of qualifying activities and cost structure
• Analysis — Technical interviews and QRE identification at the business component level
• Documentation — Comprehensive study report, credit calculations, and Form 6765 preparation
• Delivery — Final deliverables to your CPA, with audit defense support if needed

We manage the bulk of the documentation work to keep the time burden on your internal teams to a minimum.

Yes. Qualified small businesses can apply the R&D Tax Credit against payroll taxes rather than income taxes — which means startups can benefit even if they are not yet profitable.

To qualify as a "qualified small business" for the payroll offset, a company generally must:

• Have less than $5 million in gross receipts in the credit year, AND
• Have no gross receipts more than 5 years prior to the credit year

This makes the credit one of the most valuable tools available to early-stage companies with significant engineering, software development, or product development spending.

The payroll tax offset election under IRC §41(h) allows qualified small businesses to apply up to $500,000 of their R&D Tax Credit against the employer portion of Social Security and Medicare payroll taxes each year (the cap was increased from $250,000 by the Inflation Reduction Act).

The election is claimed on Form 6765 with the original tax return. The offset is then applied against payroll tax liabilities reported on Form 941 in the quarter following the income tax filing.

For a startup with $1M of qualifying R&D wages, this can mean tens of thousands of dollars of immediate cash savings — well before the company becomes profitable enough to use a regular income tax credit.

The IRS requires clear documentation that connects qualified activities to qualified costs. Per the Audit Techniques Guide, taxpayers must establish a direct nexus between QREs and specific business components.

A defensible study includes:

• Technical project descriptions and narratives
• Business component identification
• Wage allocation methodology and supporting time data
• Supply documentation tied to specific projects
• Contract research substantiation
• Comprehensive financial tie-outs
• Methodology summary aligned with §41 and §174

Contemporaneous records (created during the research) are stronger than reconstructed estimates. We prepare complete, audit-ready documentation packages designed to satisfy IRS scrutiny.

If the IRS opens an examination, having a well-prepared study is the single biggest factor in defending the claim. Our deliverables are designed for examination from day one — not patched together after a notice arrives.

A typical R&D credit examination focuses on:

• Nexus — Whether QREs are tied to specific qualifying business components
• Four-Part Test — Whether activities meet all four IRC §41(d)(1) requirements
• Base Period Consistency — Whether QREs are calculated consistently between credit year and base years
• Substantiation — Whether contemporaneous records support the claim

We provide ongoing audit defense support for clients we have engaged. Our 100% audit-free record on the studies we deliver reflects the rigor we build into every engagement.
