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.
