ViDA Single VAT Registration: How the 2028 Changes Cut Foreign VAT Registrations

Most of the attention on VAT in the Digital Age (ViDA) goes to e-invoicing and digital reporting, the pillar that lands at the end of the decade. The pillar that affects more businesses sooner is the quieter one: Single VAT Registration. Its goal is blunt. Cut the number of member states a business has to register in to do cross-border trade in the EU. For a software seller juggling multiple local VAT numbers, or a goods seller moving stock across borders, this is the part of ViDA worth understanding now.

ViDA in one paragraph

ViDA is a package of EU VAT reforms adopted in 2025 and phased in over several years. It rests on three pillars: Digital Reporting Requirements and e-invoicing (the structured-data and intra-EU reporting overhaul that arrives later in the decade), the platform economy rules (deemed-supplier obligations for certain platforms facilitating short-term accommodation and passenger transport), and Single VAT Registration (reducing the need for multiple national VAT registrations). For the foundations, see the ViDA explainer and the 2026 compliance roadmap. This article zooms in on the registration pillar.

The problem it is solving

Today, a non-established business can be dragged into a local VAT registration for reasons that have nothing to do with having an office or staff there. Hold stock in a member state, move your own goods across an internal border, or make certain B2C supplies, and you can end up registered in a handful of countries, each with its own return, language, deadlines, and quirks. The One-Stop Shop (OSS) already removed a lot of this pain for cross-border B2C digital and distance sales, but it never covered everything. Single VAT Registration is OSS philosophy pushed further into the gaps.

The three moving parts

1. A wider One-Stop Shop

ViDA extends the OSS to more supplies that currently force a local registration. The headline extension covers the transfer of own goods across member states: instead of registering in the destination country to account for moving your stock there, you report it through an OSS-style return. The intent is that a far larger share of cross-border activity can be declared through one registration in one member state.

2. Mandatory reverse charge for non-established suppliers

This is the change with the broadest reach. Where a business not established (and not identified for VAT) in a member state makes a B2B supply to a customer who is VAT-registered there, the reverse charge becomes mandatory across the EU. The customer accounts for the VAT; the supplier does not have to register locally just to handle that sale. Today the reverse charge in this situation is optional and applied unevenly between member states, which is exactly what creates accidental registration obligations. Making it mandatory removes a major reason non-established sellers register at all. If the reverse charge mechanism itself is unfamiliar, the reverse charge explainer walks through the mechanics.

3. Extended deemed-supplier and IOSS measures

ViDA broadens the situations where a platform is treated as the deemed supplier and collects the VAT, which shifts the registration and collection burden away from the underlying seller. Alongside this, the Import One-Stop Shop (IOSS) regime is reinforced as the EU continues tightening how VAT on imported goods is collected. The common thread is concentrating the obligation at the point where it can be reported through a single return.

What it means for a SaaS seller

If you sell software and digital services, you may already lean on the OSS for B2C and apply the reverse charge for most B2B sales to EU businesses. The registration pillar mostly hardens what you do today. The mandatory reverse charge removes the edge cases where a member state's optional treatment could otherwise have pulled you into a local registration on a B2B supply. The practical wins for digital sellers are smaller than for goods sellers, because the worst registration traps were always about physical stock. The benefit is fewer surprises, not a wholesale change to your model.

The reminders still apply. Get the B2B versus B2C split right, because it decides whether reverse charge or OSS is even the relevant track, and keep solid customer-location evidence, because none of these mechanisms forgives a misclassified place of supply.

What it means for a goods seller

This is where Single VAT Registration earns its name. A business that holds inventory in several member states, or moves its own stock across internal borders to fulfil orders, currently collects local registrations the way a frequent traveller collects stamps. Extending OSS to transfers of own goods, combined with the mandatory reverse charge on B2B supplies, is aimed squarely at collapsing those multiple registrations toward one. The relief is real, but it is not absolute: certain activities will still require a local number, so the work is identifying which of your flows the new measures actually cover.

How to prepare

1. Map your current EU registrations and why each exists. For every local VAT number, write down the trigger. Stock held there? Own-goods movements? An optional reverse-charge gap? That list tells you which registrations the 2028 measures could let you retire.
2. Pressure-test your reverse-charge handling. If the mechanism becomes mandatory in more places, your invoicing and your buyers' self-assessment both have to be right. Inconsistent reverse-charge treatment today is a liability tomorrow.
3. Do not unwind anything early. The measures phase in on their own timetable. Deregistering before the relevant rule is live, or before you have confirmed a flow is genuinely covered, swaps one compliance problem for another.
4. Track the pillar dates separately. The registration changes and the digital-reporting changes are different timelines. Plan against the one that applies to the specific obligation in front of you.

Frequently asked questions

What is Single VAT Registration under ViDA?

One of ViDA's three pillars. It aims to let a business meet its EU VAT obligations through a single registration instead of several, mainly by widening the One-Stop Shop, making the reverse charge mandatory in more cross-border B2B cases, and extending deemed-supplier and IOSS rules.

When does it take effect?

ViDA was adopted in 2025 and phases in by pillar. The Single VAT Registration measures are scheduled around 2028; the digital reporting and e-invoicing pillar arrives later. Confirm the date for the measure that affects you.

Does it remove foreign VAT registrations entirely?

No. It reduces them. Many supplies that force a local registration today can be handled through an expanded OSS or the mandatory reverse charge, but some situations will still need a local number.

Does it change how SaaS sellers handle EU VAT?

Mostly it reinforces current practice. OSS for B2C and reverse charge for B2B already cover most digital sales; the mandatory reverse charge closes optional-treatment gaps that could otherwise trigger a local registration.
