Omnibus Tax Act: Reverse charge tightening; energy VAT cut; softening penalties
Greece’s omnibus tax bill, was gazetted 15 May 2026, bundles VAT amendments alongside Pillar Two, DAC8 and DAC9. It is not yet enacted, but the likely implementation pattern is already clear: most VAT measures will take effect on publication in the Official Gazette, with targeted retroactivity and possible carve-outs by article.
Reverse charge: likely immediate tightening
The now passed bill refines the reverse charge for construction services. As with most anti-fraud measures, expect this to apply from the date of enactment, unless a specific article defers it. Businesses will need to reassess contractor/subcontractor flows quickly, particularly where current ERP logic is hard-coded.
Energy rate cut: possible dated trigger
Certain electricity transmission services move to the reduced 6% rate. Rate changes are more likely than technical fixes to carry a specific start date, but absent that, the default would still be on publication. Either way, invoice mapping and tax code alignment will need updating at speed. See how other countries VAT cuts on Gulf conflict measures work.
Rebates: immediate clarification, ongoing impact
The clarification of volume-based rebates is likely effective immediately as an interpretative measure. This is where VAT errors persist: timing of adjustments, linkage to original supplies, and correct return positions. Expect scrutiny here regardless of formal timing.
Penalties: explicitly retroactive
Greece is reducing or abolishing penalties for nil and credit VAT returns and late withholding filings, with retroactive effect back to April 2024. This is a clear compliance relief measure, but it does not reduce technical audit risk.
