At Cross Border VAT, we’re having the same conversation every week: “Will Single VAT Registration really eliminate all my EU VAT registrations?” The short answer is: not quite all of them, but for most businesses, implementation of single VAT registration from July 1, 2028, through OSS extension to all B2C supplies and stock transfers will be transformative.
This isn’t just another regulatory tweak. This is the biggest structural change to EU VAT compliance since the system was created. If you’re still managing multiple EU VAT registrations, your entire compliance approach is about to be upended, and you’ve got less than two and a half years to prepare.
What single VAT registration actually means
Single VAT Registration allows businesses to register for VAT in one country for sales across the EU, with OSS and IOSS schemes enabling businesses to charge VAT based on the customer’s location and pay VAT to a single tax authority.
But here’s what’s revolutionary about the July 2028 expansion: OSS will be extended to supply and install services, goods sold aboard ships, trains, and aircraft, energy through systems, zero-rated supplies, and some exempt suppliers like diplomatic or consular entities.
Currently, OSS works brilliantly for B2C distance sales of goods and digital services. From July 2028, the scope will expand to cover scenarios that currently force businesses into multiple local registrations.
We’re working with a client who maintains VAT registrations in nine EU countries, specifically for installation services. After July 2028, they could collapse all nine into a single OSS registration. The compliance cost savings alone are over £25,000 annually.
The own goods movement revolution
This is the change that’s genuinely game-changing for logistics-intensive businesses. From July 2028, businesses moving their own goods across EU borders can use OSS instead of registering in each country.
Currently, if you’re transferring stock from your UK warehouse to an EU fulfilment centre, or between EU warehouses, you need VAT registrations in both the departure and arrival countries. The administrative burden is massive.
The extension of OSS to own stock movements across EU borders will enable hundreds of thousands of e-commerce sellers and B2B businesses to significantly cut their foreign VAT registrations and associated costs, with the member state of identification for OSS registration being the country of dispatch of goods for non-EU established businesses.
What still requires local registration?
Let’s be honest about the limitations: some activities may still require local VAT registrations, such as B2B domestic supplies and margin schemes.
You’ll Still Need Local Registration For:
- Domestic B2B sales within a member state where you’re not established.
- Supplies under margin schemes.
- Certain exempt supplies.
- Services where the customer isn’t the taxable person.
- Local property transactions.
- Some installation and assembly services with specific characteristics.
Businesses may still need to register locally for domestic B2B sales, especially those outside OSS coverage or involving margin schemes and exempt supplies.
The key is understanding which activities qualify for OSS and which don’t. We’re conducting compliance audits now to help clients map their operations against the 2028 OSS scope and identify which registrations become redundant.
The reverse charge mechanism changes
A mandatory reverse charge mechanism will apply to B2B supplies by non-established and non-identified suppliers where the customer is VAT identified in the Member State of supply, with Member States given discretion to extend this to additional B2B supplies.
This simplifies compliance for foreign businesses supplying registered customers. Instead of needing local VAT registration to invoice properly, the customer accounts for VAT through reverse charge.
But there’s nuance: the proposed harmonisation of non-resident B2B domestic reverse charge rules has been modified to give member states flexibility, required to apply the reverse charge when a non-resident supplier supplies a VAT-registered customer, but with flexibility on whether to adopt different rules.
Translation: while the framework is harmonised, implementation details will vary by country. Your invoicing systems need to handle country-specific reverse charge applications.
Call-off stock simplification is ending
Here’s a significant change most businesses haven’t focused on: the call-off stock simplification will phase out between 30 June 2028 and 30 June 2029, with no new call-off stock arrangements permitted from 1 July 2027.
Currently, call-off stock allows you to transfer goods to another member state without immediate VAT registration, provided specific conditions are met. That facility disappears, replaced by the OSS’s own goods movement capability.
If you’re currently using call-off stock arrangements, you’ve got until mid-2027 to establish new ones, and existing arrangements wind up by mid-2029. You need transition planning now.
The implementation timeline you need to know
From the ViDA package adoption on 11 March 2025: January 1, 2027, brings updates to the e-commerce package and expansion of OSS to include supplies of electricity, gas, and heat; July 1, 2028, sees implementation of single VAT registration with OSS extension to all B2C supplies and stock transfers plus mandatory reverse charge mechanism.
Key Milestones:
Q1-Q2 2026:
A new draft of the Single VAT Registration papers is expected by the end of Q1 2026.
This is when technical specifications and implementation details become clear.
January 2027:
OSS expands to cover energy supplies, electricity, gas, heating, and cooling.
July 2027:
Final date to establish new call-off stock arrangements.
July 2028:
Full Single VAT Registration launch with OSS covering own goods movements and expanded service categories.
The businesses preparing now will transition smoothly. Those waiting until 2027 will be scrambling.
Technology and system requirements
New EU-wide registration data exchange layer, enhanced identification logic for non-established traders, and streamlined lifecycle management for OSS/SVR accounts will mark the point where full operational SVR replacing multiple VAT registrations begins to function.
Your ERP and accounting systems need significant upgrades:
Must Handle:
- Multiple OSS return types (sales, services, own goods movements)
- Country-specific reverse charge applications
- Integration with enhanced EU VAT registration portals
- Tracking which activities qualify for OSS vs. require local registration
- Transition from current registrations to consolidated OSS
Businesses should upgrade IT and invoicing systems to integrate with OSS, IOSS, and e-invoicing requirements, ensuring these platforms support structured invoice data and digital reporting.
Strategic planning opportunities
Large multinationals likely are aware of these upcoming changes, but many SMEs might not yet grasp that, come 2028, they could simplify their VAT setup, with success depending on businesses actually using OSS schemes properly.
Immediate Strategic Actions:
Registration Audit
Map every EU VAT registration you currently maintain against the expanded OSS scope. Which becomes redundant? Which must stay? What’s the transition path?
Supply Chain Analysis
How do your own goods movements affect your operations? Could you restructure inventory management to maximise OSS benefits?
Customer Classification Review
With mandatory reverse charge for B2B supplies, how does your invoicing need to adapt? Which customers trigger reverse charge vs. normal VAT?
Technology Roadmap
What system changes are required? When do you start development? What’s the testing timeline?
The Deregistration Question
Here’s what nobody’s talking about: how do you wind down existing VAT registrations once OSS makes them redundant?
You can’t just stop filing. Each registration requires proper closure:
- Final VAT returns submitted.
- Any outstanding assessments settled.
- Certificates of deregistration obtained.
- Records retention obligations met.
We’re developing deregistration roadmaps for clients, coordinating the wind-down of multiple registrations whilst ensuring continuous OSS coverage. The administrative choreography is complex.
Common misconceptions we’re correcting
OSS will eliminate all my VAT registrations
Not quite. Domestic B2B sales, margin schemes, and certain other activities still require local registration.
I can wait until 2028 to think about this
Absolutely not. System changes, staff training, and strategic planning require 18-24 months minimum.
My current OSS registration automatically extends to the new scope
Partially. Your registration continues, but you’ll need to update systems and processes for your own goods movements and expanded service categories.
Small businesses don’t need to worry about this
Single VAT registration reduces administrative burdens for cross-border businesses, with ViDA reducing VAT fraud by up to €11 billion yearly and lowering annual administrative and compliance costs for EU traders by over €4.1 billion over the next ten years. SMEs benefit proportionally more than large enterprises.
The Cross Border VAT preparation approach
At Cross Border VAT, we’re helping clients prepare through:
SVR Readiness Audits
Analysing current VAT footprint against 2028 OSS scope, identifying which registrations become redundant, and planning transition paths.
System Integration Planning
Working with clients’ IT teams to ensure OSS capabilities are built correctly for own goods movements and expanded service categories.
Transition Project Management
Coordinating the shift from multiple registrations to consolidated OSS, managing deregistrations, and ensuring no compliance gaps.
Ongoing Compliance Under SVR
Preparing systems and processes for expanded OSS returns covering sales, services, and inventory movements through one quarterly filing.
The businesses that will succeed post-2028 aren’t those with the most registrations today; they’re those preparing systematically for the simplification ahead.
People also ask
Q1. Will Single VAT Registration really eliminate all my EU VAT numbers?
A1. Not all of them, but potentially most. From July 2028, OSS covers B2C distance sales, digital services, installation services, own goods movements, and energy supplies. However, you’ll still need local registration for domestic B2B sales within a member state where you’re not established, margin scheme supplies, and certain exempt services.
We’re conducting audits now to help clients identify which of their current registrations become redundant; typically, 60-80% can be eliminated through SVR.
Q2. How do I handle my own goods movements under the new OSS system?
A2. From July 2028, when you transfer inventory between your own warehouses or locations across EU borders, you’ll report these movements through OSS instead of needing VAT registrations in both countries.
You’ll file a quarterly OSS return covering these transfers alongside your B2C sales. The member state of identification for non-EU businesses will be your country of dispatch. This eliminates the current requirement to register locally just for internal stock transfers.
Q3. What happens to my existing call-off stock arrangements after 2028?
A3. Call-off stock simplification is being phased out. No new call-off stock arrangements can be established after 1 July 2027, and existing arrangements must wind up by 30 June 2029. If you currently use call-off stock, you need to transition to the OSS own goods movement system by mid-2028. We’re helping clients plan this transition now to avoid compliance gaps during the changeover period.
Q4. When should I start planning for Single VAT Registration?
A4. Right now. The July 2028 implementation requires significant preparation: system upgrades take 12-18 months, staff training needs 6-12 months, and you’ll want to pilot the new processes before going live. Additionally, if you’re planning to deregister from multiple countries, that process itself can take 6-9 months per jurisdiction.
Businesses starting preparation in 2026 will transition smoothly; those waiting until 2027 will face rushed implementation and potential compliance gaps.
Q5. Will my accounting software automatically handle the expanded OSS scope?
A5. Most won’t without significant updates. Your systems need to distinguish between activities covered by OSS versus those requiring local registration.
They must handle country-specific reverse charge applications, generate expanded OSS return formats including goods movement reporting, and track compliance across the transition period as you wind down local registrations.
Ready to prepare for Single VAT Registration? We’re helping businesses audit their current VAT footprint, plan system transitions, and build roadmaps for the July 2028 implementation.
Let’s ensure you maximise the compliance simplification whilst maintaining proper coverage for activities still requiring local registration.
