ViDA, or VAT in the Digital Age, the EU's package of VAT rules for platforms and digital reporting, does not have one transition deadline. Article 6 of Directive (EU) 2025/516 splits the reform into four pieces, each with its own deadline for writing it into national law. The first, and the nearest, is 31 December 2026. By that date, member states have to adopt and publish the changes to Article 2, which take effect from 1 January 2027 and which deal mainly with the VAT role of e-commerce platforms and the OSS/IOSS special schemes, one-stop-shop mechanisms that let a business report VAT across the whole EU through a single return instead of registering in every country it sells into. These changes say nothing about e-invoicing or cross-border digital reporting yet; those come with later deadlines. If you're wondering whether 31 December 2026 means an e-invoicing mandate lands next year, the short answer is no, not because of this deadline.

What are ViDA's four deadlines?

After Article 2 (31 December 2026, in force from 1 January 2027) comes Article 3, which member states must transpose by 30 June 2028 and which covers the single VAT registration reforms, rules meant to cut down on the number of separate VAT registrations a business needs across the EU. The rule making short-term accommodation and passenger-transport platforms responsible for VAT on their sellers' behalf can take effect anywhere from 1 July 2028 up to 1 January 2030 at the latest, depending on each member state's own choice. Article 4 has to be transposed by 30 June 2029. Article 5, the one containing cross-border B2B e-invoicing and digital reporting (B2B meaning business-to-business sales), must be transposed by 30 June 2030 and applies from 1 July 2030.

What's the difference between transposition and application?

A law has to be adopted domestically before the deadline, but the rules themselves only start to bite a little later. Article 2's changes, for example, must be adopted by 31 December 2026 but don't actually apply to businesses until 1 January 2027. The same pattern repeats at every one of the four deadlines: adopt first, apply second. The transposition date and the date your business feels the change are rarely the same day.

Do the regulations need transposing too?

Council Regulation (EU) 2025/517 is binding and directly applicable in every member state as it stands. It takes effect automatically and needs no domestic law to switch it on. So the 31 December 2026 deadline has nothing to do with this regulation. It only concerns the directive and the national laws built on top of it.

Does 1 July 2030 bring a general e-invoicing mandate?

According to the European Commission, the digital reporting rules taking effect from 1 July 2030 cover cross-border B2B transactions specifically. That's not the same as requiring every domestic invoice, or every B2C sale (business-to-consumer), to be issued as an e-invoice. If your business only trades domestically, this particular deadline isn't the one to lose sleep over.

What are Estonia, Latvia and Lithuania already doing?

Estonia's amendment to the Accounting Act gives any company that has registered itself as an e-invoice recipient the right to demand a machine-readable e-invoice from its suppliers. That reform runs on its own schedule, entirely separate from the ViDA calendar above. In Latvia, sending e-invoice data to the State Revenue Service is already mandatory for G2G, B2G and G2B transactions (government-to-government, business-to-government, and government-to-business) from 1 January 2026, with the B2B segment following from 1 January 2028. Lithuania passed VAT Act amendment XV-1036 on 18 June 2026 and published it on 26 June 2026; most provisions apply from 1 January 2027, with a handful not kicking in until 1 July 2029.

Taken together, none of these three countries' current moves are the same thing as ViDA. They're domestic steps that happen to run alongside it. The dates worth marking on your calendar right now are 31 December 2026 for the first EU-wide transposition, and 1 July 2030 for cross-border B2B e-invoicing. Everything else is either a national rule with its own logic, or a later ViDA deadline that hasn't started the clock yet.

FAQ

Does ViDA December 31, 2026 mean an e-accounting obligation in 2027?

No. December 31, 2026 is the transposition deadline for the amendments to Article 2 of the Directive. They will only enter into force on January 1, 2027 and will not yet lead to a general e-invoicing obligation.

What are the four transition periods for ViDA according to Article 6 of the Directive?

According to Article 6, the deadlines are 31 December 2026, 30 June 2028, 30 June 2029 and 30 June 2030. Each will have a separate date of entry into force in national law upon implementation.

What is the difference between adoption and application in the context of ViDA?

Transposition means that a member state must adopt the rules nationally before the deadline. Application means that the rules will apply to businesses at a later date.

Does Council Regulation (EU) 2025/517 need to be transposed?

No. Regulation (EU) 2025/517 is binding and directly applicable in all Member States, so it does not require a separate national transposition act.
