Intrastat - step by step process

Intrastat step two: how to complete your Intrastat Supplementary declaration


This step outlines basic information on completing each box on the Intrastat Supplementary Declaration (SD) which you must complete monthly if your trade in goods within the European Union (EU) exceeds the Intrastat threshold, whether for Arrivals or Dispatches, or both.

Sending your data to HMRC

Please be aware you will require a separate username and password from the one you have to submit your EC Sales List and VAT Returns.

Register for E Submissions. This process takes up to 24 hours for you to receive your username and password via email. When you register to submit online, please make sure you register as the trader. An Agent can submit a declaration on your behalf but must use their own UK VAT registration in the 'Agent' box on the SD.

If you have not received a username and password within 48 hours, please email

The Application has 2 methods of completion:

Electronic Data Interchange (EDI)

To submit data electronically by email attachment, the file must be converted into the message format 'Electronic Data Interchange for Commerce and Transport (EDIFACT)' which is a United Nations International Standard.

An internet application demonstration is available by following the Electronic Submissions link at step 5.
