Greece’s Tax Bill Signals Immediate VAT Changes, Retroactive Relief and Rate Cuts

Greece’s omnibus tax bill (gazetted 15 May 2026) bundles VAT changes with Pillar Two, DAC8, and DAC9, but is not yet enacted.
Most VAT measures are expected to apply immediately on publication in the Official Gazette, with some article-specific retroactivity or carve-outs.
Reverse charge rules for construction services are likely to be tightened quickly, requiring fast ERP and contractor flow updates.
A reduced 6% VAT rate may apply to certain electricity transmission services, likely with a specific start date or otherwise from publication.
Penalty relief for nil/credit VAT returns and late withholding filings is explicitly retroactive to April 2024, while rebate clarifications are likely effective immediately.
