Spain’s new ministerial order on electronic invoicing takes effect on 1 October 2026, starting the clock for adaptation periods. Companies with annual turnover above €8 million must be compliant by 1 October 2027, while others must comply by 1 October 2028. The order activates the technical framework set out in Law 18/2022 and Royal Decree 238/2026.

The phased rollout will start on 1 Oct 2027 for large firms (€8 m+ turnover) and extend to all taxpayers by 1 Oct 2028, with payment status reporting added in 2029. The regime requires EN 16931‑UBL invoices, a faithful copy to the public system, and a free public platform built by the Agencia Estatal de Administración Tributaria.

The extension also simplifies authorisation, allowing existing e‑filing powers of attorney to be used for JPK submissions.

Belgium has increased its VAT registration threshold from €25,000 to €30,000, effective 1 January 2026.

The European Commission is advancing a deemed supplier regime for ride‑and‑accommodation platforms, with a voluntary launch in July 2028 and mandatory compliance by 1 January 2030. Draft explanatory notes were issued in Q1 2026, with final notes expected in Q2 2027, and the EC will confirm member‑state conditions by 31 December 2028.

The rule, effective April 1 2026, imposes a final deadline of April 30 2026 for submitting a Notice of Access. The mandate targets a wide range of digital businesses, including foreign operators, and presents significant technical challenges due to the lack of published API specifications.

Vietnam's Ministry of Finance has issued a draft decree to streamline e-invoicing for e-commerce and low-value transactions, shifting invoice issuance to platform operators and allowing small businesses below thresholds to issue consolidated daily invoices.

A June 2024 directive urges the remaining non‑compliant businesses, especially retail outlets, to adopt e‑invoicing, following the successful Phase 2 rollout in 2022 that registered 92 % of obligated taxpayers.
