DMBM401020 - Interest: interest on late payments: due dates

Some content of this manual is being considered for archiving. If there is content you use regularly, please email hmrcmanualsteam@hmrc.gov.uk to let us know as soon as possible.

Due dates for payments are generally a fixed number of days after the end of an income tax year, return period ended or after the issue of a Charge Notification (CN). The number of days can differ across the wide range of charges dealt with by HMRC. The due date for payment is not always the same date from which interest will accrue.

Where the tax or duty is determined on time and the CN is also issued in good time the due date for payment will often be the date from which interest starts to accrue. Where a CN is issued for an earlier year or period then the due date for payment will be a number of days forward in time, for example to allow for an appeal. However the date from which interest starts to accrue can be a much earlier date when the tax/duty should have been paid for the specified year or period.

No interest is payable where a payment is received for an interest bearing charge on the date from which interest starts to accrue.
