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 email@example.com.
The Application has 2 methods of completion:
- online form - this is an ideal option for submitting small amounts of data using Arrival and Dispatch forms
- offline option - this is the preferred option for submitting larger amounts of data, and uses a pre-prepared Excel spreadsheet
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.
