EU VAT in the Digital Age: 2026 Implementation Work and the 2027 Changes

Executive Overview

The European Union's VAT in the Digital Age package was adopted in 2025 and is now moving through phased implementation. During 2026 the European Commission published its implementation work programme and, in July, revised explanatory notes and OSS guidance reflecting the changes that apply from 1 January 2027. The reform is not a single VAT amendment but a structural reorganisation of how cross-border VAT is reported and administered.

Switzerland is not an EU Member State, and the package does not change Swiss domestic VAT. It is nevertheless directly relevant to Swiss businesses, because non-EU establishment does not remove EU VAT obligations where a business has taxable transactions in Member States. For Swiss sellers, platforms and service providers, the question is whether their existing EU VAT footprint is compatible with the reform timeline.

Regulatory Background

The package covers three broad areas: digital reporting and e-invoicing for cross-border business-to-business transactions; a revised VAT treatment for parts of the platform economy; and a Single VAT Registration framework intended to reduce the need for multiple registrations across Member States. Major elements phase in between 2027 and 2030, with further alignment through 2035.

The 2026 work is preparatory. The revised OSS and IOSS guidance issued in July 2026 is intended to support the changes applying from 1 January 2027, and the Commission's work programme sets out the implementation sequence. Because the reform is phased, businesses should distinguish carefully between what applies from 2027 and what is scheduled for later stages, and should avoid restructuring today for obligations that arrive at the end of the decade.

Why It Matters

The reform affects how VAT is reported and where registrations are required, which means it reaches businesses that consider their EU exposure settled.

• Swiss companies selling goods into the EU, whether directly, through distributors or through fulfilment arrangements.
• Swiss service providers with taxable supplies in Member States, including digital and electronically supplied services.
• Businesses using OSS or IOSS, whose reporting and registration approach may be affected by the 2027 changes.
• Companies selling through marketplaces and platforms, where the VAT treatment of the intermediary is part of the reform.
• Groups holding multiple local VAT registrations, for which the Single VAT Registration framework may change the structure.
• Finance and IT functions responsible for invoicing systems, which will need to accommodate digital reporting and e-invoicing requirements.
• Advisers reviewing supply chains, contracts and invoicing flows against the phased timeline.

Practical Issues to Review

1. 01Map the transaction flows: where goods physically move, where services are supplied, who invoices whom and under which VAT registration.
2. 02Identify all current EU VAT registrations and the reason each one exists, distinguishing those driven by physical presence from those driven by reporting requirements.
3. 03Review current OSS and IOSS use against the revised guidance issued in July 2026 and the changes applying from 1 January 2027.
4. 04Assess platform and marketplace relationships to determine who is treated as the supplier for VAT purposes in each flow.
5. 05Examine invoicing systems and data quality against the direction of the digital reporting and e-invoicing requirements.
6. 06Build a phased internal timeline distinguishing 2027 obligations from the later stages through 2030 and 2035.
7. 07Confirm contractual responsibility for VAT compliance with distributors, platforms and logistics providers.

TCC View

Our starting point in this area is always a transaction-flow map rather than a rules summary. Most VAT surprises in cross-border trade originate not in a misunderstanding of the legislation but in a mismatch between what the contracts say, what the logistics actually do and what the invoicing system produces. Once the flows are documented, the ViDA timeline can be overlaid on them and the genuinely affected points become visible, usually a smaller set than expected.

The second point is sequencing. Because the reform phases in over several years, there is a real risk of restructuring prematurely for requirements that are not yet defined in operational detail. The more effective approach is to address the 2027 changes concretely, ensure that invoicing and data systems are capable of supporting structured digital reporting, and keep the later stages under review. Swiss businesses in particular should be clear that their non-EU status is not a shield: it affects how obligations are discharged, not whether they exist.

Planning Note

Before making structural changes, Swiss businesses selling into the EU should complete a transaction-flow map, confirm their current registrations and OSS or IOSS position, and identify the invoicing and data changes that would be required to support digital reporting. Contracts with platforms, distributors and logistics providers should be reviewed for VAT responsibility. The implementation timeline should then be monitored, so that changes are made when the applicable requirements are settled rather than in anticipation of them.
