Research and Development (R&D) Relief limit for employees

The amount of relief you can claim in any tax year is limited by your effective rate of tax for that year. Your Income Tax payable must be at least 23% of your total income for the claim year. The minimum threshold of 23% applies both before and after claiming the relief.

This also applies each year you carry forward the Research and Development (R&D) Tax Credit.
