Penalty interest rate set to rise again
The Bank of England raised its base rate again in June, and HMRC has confirmed the penalty rate of interest on late-paid tax will follow suit. What will the new rate be and when will it start to apply?

The base rate has been increased several times already in 2022 as the Bank of England attempts to exert some control on spiralling inflation. The latest increase (on 16 June) set the rate at 1.25%. This means that HMRC’s penalty interest rate will rise to 3.75% (up from 3.5%). HMRC has confirmed that this will take effect from 27 June for quarterly instalment payments, and from 5 July for everything else.
