Details and caveats

Transaction data is reported to the tax authority's myDATA platform, which pre-fills VAT returns (since 1 Jan 2024) and income tax returns. B2B status is shown as unknown because we could not fetch an official source: on 11 Oct 2026 aade.gr, gov.gr and hellenicparliament.gr refused our requests (HTTP 403) and the Government Gazette download failed; the EC factsheet (re-checked 11 Oct 2026, content last updated Aug 2025) only says Greece plans to amend its legislation after ViDA. Secondary (non-official) reports describe a phased B2B mandate under Law 5222/2025 starting in 2026; we have not verified this. Check aade.gr directly.
