Making a late supplementary declaration

Find out how to submit a supplementary declaration when you've missed the deadline.

If you’re unable to submit your supplementary declaration for the current accounting period by the due date, you’ll need to submit an estimate of the taxes due.

What you’ll need 

As part of the estimate, you’ll need to gather the following information:

  • the sender’s name and position within the company or relationship to the simplified customs declaration process authorisation holder
  • the simplified customs declaration process authorised trader’s name and EORI number
  • the period that will be late, for example, January 2024
  • the total number of supplementary declarations not submitted in time
  • an estimate of the total amount of revenue due but not paid on the outstanding supplementary declarations — this estimate should be broken down into customs duty, excise duty and VAT, unless you confirm that you use postponed VAT accounting (PVA) as applicable
  • the deferment account number (DAN) from which the revenue due should be debited

If you’re acting as an simplified customs declaration process authorised direct or indirect representative for a customer and you require the taxes due to be debited from the customer’s account, you’ll need to provide your:

  • EORI number
  • customer’s EORI number
  • customer’s deferment account number

If there is no revenue due, you must still provide the total number of supplementary declarations which will not be submitted.

When to submit

You must submit an estimate to the Simplified Customs Declaration Process (SCDP) National Assurance Team by the accounting deadline. This is by 5pm on the 10th calendar day of the month following the end of the accounting period, unless you’ve been notified of a different date.  

How to submit

Send your estimate to the SCDP National Assurance Team.
