Re-checked 2026-09-09: vmi.lt/evmi/pelno-mokestis is reachable but is a collapsed navigation menu with no extractable article text on quarterly advance payments this session.

Placeholder – no application date exists. Commission proposal COM(2023) 533 remains open: Parliament adopted its position in April 2024, but the file is classified 'Blocked' by the European Parliament's Legislative Train Schedule (no Council progress for 9+ months, as of Aug 2026) and 'Ongoing' by the EUR-Lex procedure tracker — not withdrawn, despite some secondary sources claiming so.

Lithuania: mandatory domestic B2B e-invoicing remains an unofficial expectation, not an adopted or announced plan

CORRECTED 2026-09-08: no official Lithuanian source (e-Seimas, e-TAR, Ministry of Finance, or VMI) confirms an adopted law, a bill before the Seimas, or even a published government target date for a domestic B2B e-invoicing mandate. The '2028' date in this entry is carried over only as the European Commission's own tracking estimate (not an LT government commitment) and should be treated as unconfirmed. What IS confirmed officially: B2G invoicing to public-sector bodies has been mandatory via the state's SABIS platform since it replaced the earlier 'E. Sąskaita' system on 2024-07-01, and VMI guidance (2024-09-10) references SABIS for VAT invoicing, including reverse-charge cases under PVM įstatymo 96 str. B2B e-invoicing remains voluntary. Any future domestic B2B mandate will also need to align with the EU's adopted ViDA package, which sets an EU-wide cross-border digital VAT reporting/e-invoicing requirement from 2030-07-01 regardless of national timing.

Public-sector suppliers already (B2G via SABIS, mandatory). No B2B-invoicing business is yet legally required to change anything, but VAT-registered businesses issuing B2B invoices would be affected if/when a mandate is adopted.

ViDA: mandatory e-invoicing and near-real-time digital reporting for intra-EU B2B transactions

Every VAT-registered business that sells goods or services to businesses in other EU countries, whatever its size.

ViDA: national e-invoicing/reporting systems must be interoperable with the EU standard

Businesses operating in several EU countries with different national e-invoicing regimes.
