Business Rates: Transitional Relief April 2026 - March 2028

The Welsh Government will provide transitional relief to all ratepayers whose liabilities will increase by more than £300 following the revaluation. Any such increases will be phased in over two years. Eligible ratepayers will pay 33% of their additional liability in the first year (2026-27) and 66% in the second year (2027-28), before reaching their full liability in the third year (2028-29). £116m will be provided over two years fully to fund this relief, supporting all areas of the tax-base in a consistent and straightforward manner.
