R&D relief guidance

This guidance explains what R&D is and the different types of relief you can claim.

R&D relief for small or medium-sized enterprises (SMEs)

You can claim SME R&D relief if you’re a SME with:

  • less than 500 staff
  • a turnover of under 100 million euros or a balance sheet total under 86 million euros

You can find information about this relief in our ‘Making R&D easier for small companies guide’.

SMEs that have not claimed R&D relief before can apply for Advance Assurance.

Research and Development Expenditure Credit

Any company can claim Research and Development Expenditure Credit (RDEC) for working on R&D projects.

It can also be claimed by SMEs and large companies who have been subcontracted to do R&D work by a large company.
