HMRC late payment interest rates to be revised after Bank of England increases base rate
It was announced on 11 May 2023 that The Bank of England Monetary Policy Committee would increase the Bank of England base rate to 4.5% from 4.25%.
HMRC interest rates are linked to the Bank of England base rate. Therefore HMRC interest rates for late payment and repayment will increase.
These changes will come into effect on:
22 May 2023 for quarterly instalment payments, and
31 May 2023 for non-quarterly instalments payments.
