HMRC penalties and surcharges are subject to interest charges, as with all other outstanding amounts of tax owed to HMRC.

You should note that if there are still amounts of unpaid tax owed to HMRC, interest will be charged both on the unpaid amounts as well the penalties that have been applied by HMRC. Charges can mount up quickly, so if you have outstanding amounts owed to HMRC you should try and come to an agreement about how to repay those amounts to stop the debt from escalating.

What if I Don’t Agree with the Penalty?

If you don’t agree with the penalty or think you have mitigating reasons for why the penalty should be waived, you should appeal to HMRC using the form they would have sent you with the notice of the penalty. If you still do not agree with HMRC’s decision, you can request for the decision to be reviewed by an independent officer, or appeal to the Tax Tribunal.
