Our R&D tax credit calculator


Our R&D tax credits calculator only gives a rough estimate of the potential corporation tax saving or R&D tax credit payable that you may be eligible to claim. It is based upon your R&D costs entered. We recommend a thorough review to make sure you identify all qualifying R&D projects and all eligible costs. In our experience, companies that submit their R&D tax relief claims themselves, or through a non-specialist, often end up significantly under-claiming.
