HMRC is decreasing interest rates for late payments for most taxes, after the Bank of England’s decision to reduce the base rate to 5%.
From 12 August 2024, the rate for late paid corporation tax quarterly instalment payments is 6%, while the rate paid on overpaid quarterly instalment payments and on early payments of corporation tax not due by instalments falls to 4.75%.
The new rate for other late paid taxes is 7.5% and repayment interest rate lowers to 4%. These take effect from 20 August 2024.
