Introduction to VAT OSS

📘 What Is VAT OSS?

Overview

VAT OSS (One Stop Shop) is a simplified EU VAT reporting system for UK businesses selling digital services to EU consumers (B2C).

Under these rules, the UK business must charge VAT at the rate applicable in the customer’s EU country - not the UK rate.

VAT OSS allows the business to report and pay all EU VAT in a single return, rather than registering for VAT in multiple EU member states.

🔍 Key Features of VAT OSS

• B2C only: VAT OSS applies only to Business-to-Consumer sales.
  • B2B sales are excluded, as they fall under the reverse charge regime.

• Digital Services:

  Defined by HMRC as services delivered electronically, where minimal human intervention is involved.

  Typical examples include:

  • Software and mobile apps
  • E-books or digital publications
  • Web hosting and cloud services
  • Online courses or streaming
  • Online advertising

Sales of physical goods or consultancy services are not covered by VAT OSS.

• Quarterly Reporting:

  Returns are filed every calendar quarter, with a single payment made to your chosen EU tax authority (many UK businesses choose Ireland, as English is widely used).

  That authority then distributes the VAT to each relevant EU country.

📊 What a VAT OSS Return Looks Like

A VAT OSS return summarises:

• The value of sales made to each EU country.
• The VAT rate and total VAT due per country.

💡 In this example, the total VAT owed across multiple EU countries is £14,962.70. The UK business makes one payment to the chosen EU authority, which then redistributes it appropriately.

🕓 Filing Deadlines

VAT OSS returns follow the calendar quarter, with the following due dates:

All returns and payments must be submitted within 30 days of the quarter end to avoid penalties.

💡 Registration Threshold

You must register for VAT OSS once your EU B2C sales exceed €10,000 per year.

Below this threshold, you can treat your EU customers as if they were based in the UK (charging UK VAT rates, if applicable).

📍 Determining Customer Location

To apply the correct VAT rate, you need to identify where your customer is located.

Businesses must normally obtain two pieces of non-contradictory evidence, such as:

• Customer’s billing address
• IP address of the device used
• Customer’s bank details
• SIM card country code
• Location of fixed landline or access point
• Other commercial data linking the sale to a specific jurisdiction

💡 For UK micro-businesses below the UK VAT threshold, it’s acceptable to rely on one piece of evidence (for example, the billing address or payment provider information).

💡 Selling Through App Stores

If you sell digital products through third-party platforms such as Apple’s App Store or Google Play, you do not need to register for VAT OSS.

These platforms act as the deemed supplier, meaning:

• They handle VAT collection and reporting for all international sales.
• You only need to account for your net revenue received from the platform.

✅ Summary

• VAT OSS simplifies EU VAT reporting for digital B2C services.
• Register once, file quarterly, and pay via a single EU tax authority.
• Registration becomes mandatory once EU sales exceed €10,000 per year.
• Keep clear records of customer location evidence.
• App Store and Google Play sellers are covered by the platform - no VAT OSS required.
