Your Trusted Partners in R&D Tax Credit Excellence

At Lewis.cpa, our R&D tax credit practice is built on precision, depth, and an unmatched understanding of the tax code’s technical terrain. For over four decades, we’ve worked at the intersection of tax law, finance, and industry-specific innovation, helping identify qualifying activities others routinely miss.

Our team approaches every claim as an investigative process, mapping your projects, processes, and expenditures against the exacting standards of federal and state regulations. We combine this technical mastery with a practical understanding of how businesses operate — whether that means analyzing complex manufacturing workflows, deconstructing software development cycles, or tracing the incremental improvements that qualify under the law.

We don’t simply “prepare” R&D claims — we build airtight, data-backed submissions that withstand scrutiny to provide you with the full value of every eligible credit while minimizing disruption to your operations.

Our Services That Maximize Your R&D Tax Credit Benefits

We provide end-to-end R&D tax credit support — from uncovering hidden opportunities to defending your claim under examination:

For businesses new to the R&D credit or looking to revisit past opportunities, our full-scale analysis of your operations identifies every eligible activity and expense. Our process is built to maximize your benefit while anticipating and addressing potential exam challenges, drawing on up-to-date interpretations of evolving tax law and recent case rulings.

Credit Accuracy & Optimization Reviews

Federal & State Exam Representation

When an IRS or state inquiry arises, we act as your dedicated liaison — managing communications, organizing supporting documentation, and guiding you through the process.

FAQ

  • What is the R&D Tax Credit?

    The R&D Tax Credit is a federal incentive designed to reward businesses for investing in innovation. It allows companies to reduce their tax liability by claiming eligible expenses related to developing new products, processes, or technologies — or improving existing ones.

  • What activities qualify for the R&D tax credit?

    Your research activities must meet four specific IRS criteria, including: developing new or improved business components, eliminating technical uncertainty, using a process of experimentation, and being technological in nature. We help evaluate your activities against these requirements to maximize your qualifying expenses.

  • What expenses can be included in R&D credit calculations?

    Qualified research expenses include employee wages for research staff, supplies consumed in research, contract research payments, and cloud computing costs for research activities. We’ll help you capture all eligible expenditures while avoiding common compliance pitfalls.

  • How much can my business save with the R&D tax credit?

    The potential savings depend on your qualified research expenses and chosen calculation method. The regular credit typically ranges from 6.5% to 13% of qualifying expenses, while the alternative simplified credit provides 14% of expenses exceeding the base amount. Many businesses save tens of thousands to millions annually.

  • What documentation is required for R&D credit claims?

    Essential documentation includes financial records, time tracking data, project documentation, employee wage records, supply receipts, and technical specifications. Lean on our team for help with organization, as we’re here to compile all necessary detailed documentation to support your claims.

  • Can I claim credits for previous tax years?

    Yes, you can typically amend tax returns for up to three years to claim unclaimed credits. Our team specializes in identifying retroactive opportunities and managing the amendment process to maximize your total benefit.

  • How does the alternative minimum tax affect R&D credits?

    The R&D credit can generally be used against both regular tax and alternative minimum tax. However, specific rules apply depending on your business structure and credit year. We analyze your complete tax situation to optimize credit utilization.

  • How long does the R&D credit study process take?

    A typical R&D tax credit study takes 4-8 weeks, with the exact timeline depending on company size, complexity of research activities, and documentation availability. We work efficiently to minimize disruption to your operations while ensuring thorough analysis.
