Thank you for contacting the Community.
If you use the standard 20% VAT code this will hit Box 1 and Box 6 on your return for sales. It will not however hit box 8. 0.0%ECG will hit boxes 6 and 8 for sales. At the moment we do not have a code that will hit boxes 1,6 and 8 at the same time.
As my colleague mentioned I would recommend to visit HMRC's website or give them a call to fully understand which VAT code to use and when whilst dealing with EU sales.
Thanks, Carly. :)
