HM Revenue and Customs (HMRC) will raise interest rates for late tax payments and repayments following the Bank of England’s increase in its base rate from 3.75% to 4.00%.
The Bank of England Monetary Policy Committee announced the increase on 5 November 2026. HMRC interest rates are linked to the Bank of England base rate.
The changes will take effect on 16 November 2026 for quarterly instalment payments and on 24 November for non-quarterly instalment payments. Information on payment interest rates will be updated shortly.
