Brexit - when to remove GB as an EU member in 'ISO Country Codes'

“As from 2021 country code GB is no longer expected to have the checkbox for EU member selected in ISO Code Usage for Countries. From an Intrastat perspective, any EU countries dealing with customers or suppliers using country code GB should no longer report any Intrastat and instead the reporting will be done through normal customs declarations, as for any country outside EU.

For UK companies however, they should still be reporting Intrastat for country GB during 2021 when it comes to Import, but not Export.

The CORE solution is dependent on that the EU member checkbox is selected to even be able to start the Collect Intrastat job. To support companies operating in multiple EU countries, both UK and others, and where it is not an option to temporarily switch on the EU member flag just before collecting Intrastat for country GB, there will be some enhancement done to introduce functionality where the EU member setting for country code GB can be overruled when collecting the Intrastat.

Here the intention is to introduce a new checkbox in the Collect Intrastat dialog that says

"Include Country GB"

This new checkbox will be automatically selected by the system if the Country entered to collect Intrastat for is GB. And if this checkbox is selected, the expected behaviour is that the system will carry on the Intrastat collection just as if the EU member checkbox is selected for GB.

This implies that still both Import and Export transactions are collected. But when submitting the information to the authotirites, only the Import declaration is submitted, since anyway Import and Export are always submitted separately. So it is just that Export is left out to create any file to submit.”
