A procedure granting VAT registration for a taxable person non-established in an EU Member State was issued under Decision No. 1152 by the Greek Office Gazette.
Decision No. 1152 explains the following:
To register under the special regime of Article 47c of the VAT code for EU non-residents, they are required to obtain a VAT number for VAT obligations. Given that it did not appoint any tax representative, VAT is granted by submitting the declaration in Annex I of the decision. The implementation took effect on 7 November 2022.
