My client in the EC has overpaid, and his invoices are processed using EC reverse charge VAT.
The VAT Return period is ending this month, and Quickfile’s calculations show a prepayment in Box 6 and the corresponding VAT in Box 1.
However, this client has another invoice outstanding and still is an EC customer (i.e. EC reverse charge VAT applies) I think this is an error in calculations and, if I were to file using Quickfile, errorneous.
I just called HMRC and explained the situation, and they suggested it might be a bug, and to file manually for this quarter instead.
I will check this in more detail tomorrow morning alongside a developer to ensure everything is working as expected.
However, we always recommend you download the calculations before submitting to HMRC. VAT is a bit of a minefield with various schemes in play!
You can still submit through QuickFile if you wish, but apply any manual adjustments before submitting it. If in doubt about the figures or calculations, I would check them with your accountant to be sure everything is correct.
