Interest: taxes and duties covered

You must check whether, and from which date, the FA 2009 interest rules apply to the tax or duty you are dealing with. See below for full details.

Late payment interest and repayment interest apply to any amount that is payable

  • by a person to HMRC, or
  • to a person by HMRC,


  • that amount is payable ‘under or by virtue of an enactment’, see CH140240, and
  • a Treasury Order has appointed a day from which the interest rules apply for a particular tax.

Eventually, all taxes, duties (other than customs duties), penalties and surcharges will be amounts that are subject to late payment interest and repayment interest because they are all due under or by virtue of an enactment. However, the interest provisions currently only apply to certain taxes and any associated penalties, see below. This is because they are the only taxes for which there is an appointed day from which the rules apply.

What the interest provisions do not apply to

The FA 2009 interest provisions do not currently apply to any taxes or duties that aren’t listed above.

There is no intention to apply the interest provisions to customs duties.

Even once the interest provisions have been extended to all taxes, duties, penalties and surcharges, they will not apply to late payment interest and repayment interest. This means that interest is not charged or paid on interest.
