ERIS: Enhanced R&D Intensive Support for UK SMEs – Specialist Guidance from Tax Advisory Partnership
The Enhanced R&D Intensive Support (ERIS) provision delivers extra tax relief for R&D-intensive, loss-making SMEs under the new merged UK R&D tax regime. If your business spends at least 30% of total costs on R&D, you may qualify for this valuable support.
What is ERIS?
ERIS is an enhanced rate within the merged UK R&D tax regime, available to loss-making SMEs whose R&D expenditure is at least 30% of total company costs. It provides a higher tax credit rate than the standard merged scheme, which is based on the R&D Expenditure Credit (RDEC).

- ERIS tax credit rate: Up to 27% of qualifying R&D spend
- Enhanced support: Designed for innovative, high-growth SMEs
