Division context — Protocol 10, Green Line, jurisdiction
This page covers, strictly factually and neutrally, a point with concrete bearing on invoicing: Cyprus's particular situation under European Union law. The Republic of Cyprus has been an EU member since 2004. However, under Protocol 10 of its Accession Treaty, the application of the EU acquis (including VAT and e-invoicing rules) is suspended in those areas where the government of the Republic does not exercise effective control. For a company, this determines which VAT regime and which identifiers apply. The subject is presented here purely from a legal and operational angle, based on EU texts.
History — Protocol 10 of the 2003 Accession Treaty
On Cyprus's accession to the EU, the 2003 Accession Treaty included a specific Protocol 10. Its Article 1 provides that the application of the EU acquis is suspended in those areas of the Republic of Cyprus where its government does not exercise effective control. This suspension is a legal mechanism: it does not alter the membership status of the Republic of Cyprus, which remains the member state for the whole island under Union law, but it acknowledges that in practice the acquis cannot be implemented there. The Council may lift the suspension.
Governance — where the EU acquis applies
Question | Answer per EU legal sources
--------------------|-------------------------------------------------------
EU member | The Republic of Cyprus (the whole island de jure)
EU acquis applied | In areas under the effective control of the government
Acquis suspended | In areas where the government does not exercise
| effective control (Protocol 10 of the Accession Treaty)
Trade across line | Governed by Regulation (EC) No 866/2004 "Green Line"
VAT / PEPPOL | The ΦΠΑ system + CY PEPPOL = Republic of CyprusFrom an e-invoicing and VAT standpoint, the consequence is direct: the obligations described in the other pages of this dossier (ΦΠΑ VAT, B2G PEPPOL, TAXISnet, CY identifiers) belong to the Republic of Cyprus and apply in the areas under its effective control. Where the acquis is suspended, these systems are not operated by the EU.
The Green Line Regulation 866/2004
Regulation (EC) No 866/2004, the "Green Line Regulation", was adopted by the Council to govern the movement of persons and goods across the dividing line, pending a settlement of the Cyprus question. It sets out, among other things, the conditions under which certain goods may cross the line, the applicable controls and the accompanying documents. It is regularly updated by Commission implementing regulations.
Consequences for invoicing
- VAT identifier: the
CY+ 8 digits + letter number is issued by the Republic of Cyprus Tax Department and recognised in VIES. - E-invoice rail: B2G PEPPOL and the Treasury portal are those of the Republic of Cyprus.
- Crossing the line: movements of goods across the line follow the documents and controls set by Regulation 866/2004, distinct from a classic intra-EU supply.
- Documentary caution: where the applicable jurisdiction of an operation is in doubt, refer to EU texts and the competent tax administration.
VAT, identifiers and jurisdiction
- Simple rule: a
CYidentifier valid in VIES and a CY PEPPOL connection point back to the Republic of Cyprus framework. - Specific trade: any flow crossing the line is to be handled under Regulation 866/2004, not as ordinary intra-EU trade.
- Neutrality: this note is limited to the legal and operational aspects of invoicing, with no political assessment.
Common pitfalls
- Treating a line crossing as an ordinary intra-EU supply. The applicable regime is that of Regulation 866/2004, with its own documents.
- Assuming a "CY" VAT number where the acquis is suspended. The ΦΠΑ system belongs to the Republic of Cyprus; a valid CY number is verified in VIES.
- Editorialising. Documentarily, sticking to EU texts (Protocol 10, Regulation 866/2004) avoids any ambiguity or bias.
