What is VAT OSS?

One portal, one declaration, all of the EU

Since 1 July 2021, the One-Stop Shop (OSS) replaces country-by-country VAT registrations for cross-border B2C sales inside the EU. You charge the buyer’s country VAT rate, declare it once per quarter via your home tax portal, and pay a single amount.

OSS becomes mandatory for distance sales above €10,000 of cross-border B2C revenue per year. Below that threshold you can stay on your home VAT rate or opt in voluntarily.

  • B2B sales: invoiced ex-VAT (reverse charge) after VIES check
  • B2C sales (EU): VAT at the buyer’s country rate, declared via OSS
  • B2C sales (non-EU): exports, ex-VAT
Why it matters

Stay compliant without slowing your team down

A single EU declaration
No more registering for VAT in each Member State — one quarterly OSS return covers all your cross-border B2C sales.
Right rate, every time
The destination-country VAT rate is applied automatically based on the shipping address and product category.
Audit-ready records
A 10-year register per buyer country is built and kept in sync between your store and your invoicing software.
How Order Invoicer helps

OSS automation across your stack

OSS-eligible sales detection
We tag every B2C order shipping to another EU country as OSS, and route it with the correct rate to your invoicing software.
VIES VAT number verification
Buyer VAT numbers are validated against the VIES database so B2B invoices are issued ex-VAT (reverse charge) when applicable.
Country-specific VAT rates
Up-to-date rates per Member State are applied to each invoice — no manual mapping or rate spreadsheets to maintain.
Quarterly OSS report
Export the totals you need (taxable amount, VAT, country) to file your OSS declaration in a few minutes.
