RSTP4003 - Interest on late payment of penalties

RSTPA guidance on the circumstances in which Revenue Scotland can charge interest for late payment of penalties.

We will charge you interest on the amount of any unpaid penalty (but not a penalty for failing to make a required repayment to us – see RSTP3003) from the date on which the penalty is due to be paid until you pay it. See RSTP3001 for further guidance on penalties.

‘Unpaid penalty’ means a penalty which you have not paid to us in full by the due date.

The percentage per annum interest rate we charge for late payment of a penalty is the Bank of England rate + 2.5%.

Please see the ‘Interest Rates’ table on the following page for full details of the current and historical rates of interest - RSTP4001 - Interest | Revenue Scotland.

The interest charged is simple interest, not compound interest. This means that late payment interest is only calculated on the amount of the unpaid penalty and not also on late payment interest that has already been charged or accrued.
