Selling goods to customers in the European Union (EU) from outside the EU presents unique VAT challenges. Fortunately, the Import One-Stop Shop (IOSS) scheme simplifies VAT compliance for distance sales of low-value goods. But how do you obtain an IOSS number?

As a registered IOSS intermediary based in Slovakia, LumioPro is here to guide you through the process and manage VAT compliance on your behalf.

What is the IOSS?

The Import One-Stop Shop (IOSS) is a system introduced by the EU to simplify VAT reporting for businesses selling goods with a value of €150 or less to EU consumers. These goods must be shipped from outside the EU and sold directly to end customers.

By registering for the IOSS, sellers can collect VAT at the point of sale and report it through a single monthly return—eliminating unexpected charges or delays for the customer at delivery.

Who Needs an IOSS Number?

An IOSS number is essential if:

You are a non-EU business selling goods valued under €150 to customers in the EU,
The goods are shipped from outside the EU,
You are not using an online marketplace that handles VAT on your behalf.
