Details for intra-Community supply
For a tax-exempt supply to another EU country, the VAT IDs of seller and buyer and a note referring to the tax exemption must be shown on the invoice (Section 14a(3) of the German VAT Act (UStG)).
What to do now
Who has to fix this?
The issuer has to fix this by issuing a corrected invoice. As a recipient you should insist on it: if a mandatory detail is missing, the tax office can refuse the input VAT deduction.
Where this rule comes from
This check does not come from the technical standard but from the German VAT Act (UStG). Section 14(4) lists the details every invoice issued by a German business must contain; Section 14a adds special cases such as reverse charge and intra-Community supplies. Billvox checks them in addition to the standard because a technically valid e-invoice can still be incomplete for tax purposes. Invoices from businesses outside Germany are governed by the law of their own country; this check is not applied to them.
