HMRC late payment interest cut by 0.25%

08 Aug 2024

HMRC will reduce late payment and repayment interest rates following the cut to the base rate.

The Bank of England cut the base rate to 5.0% on 1 August, the first reduction for over four years.

This has triggered a cut in HMRC interest rates which are pegged to the base rate.

From 20 August, the late payment interest rate will be cut to 7.5% from 7.75%, where it has been for the last 12 months. The repayment interest rate will reduce to 4.0% from 4.25% from 20 August.

HMRC late payment interest is set at base rate plus 2.5%. Repayment interest is set at base rate minus 1%, with a lower limit - or 'minimum floor' - of 0.5%.

Corporation tax self assessment interest rates relating to interest charged on underpaid quarterly instalment payments will drop to 6.0% from 6.25% from 12 August.

HMRC continues to pay lower interest to taxpayers affected by overpayments of tax at 4.75% from 12 August, down from 5.0%.

The interest paid on overpaid quarterly instalment payments and on early payments of corporation tax not due by instalments is down by 0.25% to 4.75% from 5% from 12 August.
