Man with boxes filling in paperwork

Next month (May) TSS will make an upgrade to its service allowing you to use your own Duty Deferment Account (DDA) to pay any duty calculated in your supplementary declarations.

Using your own DDA provides the cashflow benefit of deferring customs duty, import VAT and excise duty for an average of 30 days.

If you do not currently have a DDA and wish to obtain one for GB to NI movements you should follow these steps:

  1. You will need to apply for a new DDA for movements to NI and for authorisation to use a customs comprehensive guarantee.
  2. Once HMRC has processed your application, you will be told the amount of the guarantee you are required to provide. You will then need to get a guarantor to cover this amount. You should allow plenty of time to complete this process. A Deferment Approval Number (DAN) will be provided to you as part of the approval process
  3. As the account holder, you must authorise TSS to use your DAN, before TSS can use your duty deferment account to add the duty charges. You can do this by logging into the Customs Declaration Service (CDS) dashboard and using the ‘View your customs financial accounts’ service
  4. You will need the TSS EORI number to complete the standing authority on CDS and this can be found on your TSS account profile through the portal 5. Once the standing authority has been granted, you must log back in to your TSS account and complete the YES/NO field against the statement ‘I have provided authorisation to TSS on my CDS account to use my DDA details on my behalf’
    If you do not give TSS authorisation, you will not be able to use your own DDA to make duty payments for declarations made through TSS and instead be required to use the TSS DDA
