Can I reuse a previous R&D tax credit claim?

It’s natural for R&D projects to take a few years to complete. You cannot reuse a previous R&D tax credit claim. You cannot recycle or reuse a previous research and development (R&D) tax credit claim. Each claim must be assessed independently, considering the eligibility of your qualifying R&D activities and expenditures. However, if your work is ongoing and continues to address technological or scientific uncertainties, a single project can span multiple years for claiming purposes.
