What is the IOSS?
The Import One-Stop Shop (IOSS) is a system set up by the European Union (EU) to make VAT collection easier for businesses selling goods worth up to €150 to customers in the EU. Before this system, businesses had to register for VAT in every EU country they sold to, which was complicated and costly. Now, businesses can register in just one EU country and handle VAT for all their sales across the EU. This makes the process much simpler.
IOSS is especially helpful for businesses outside the EU that want to sell to EU customers without having to register for VAT in each EU country.
How Does IOSS Work?
- Registration Process
First, businesses must register with the tax authority in one EU country. After registering, they’ll receive a unique number to include in customs forms for eligible shipments. Non-EU businesses may need help from an intermediary, like a tax consultant or shipping company. - VAT Collection at Checkout
VAT is charged when a customer buys something, based on where they live. The final price, including VAT, is shown at checkout, so customers know exactly how much they’ll pay before buying. This avoids unexpected VAT charges later, improving customer satisfaction and reducing cart abandonment. - Faster Customs Clearance
Since VAT is paid in advance, goods move through customs more quickly. Without prepaid VAT, shipments can get delayed at customs, which can increase wait times and fees. Prepaid VAT helps shipping services process orders faster, so deliveries are quicker. - VAT Reporting & Payment
Each month, businesses must send a report to the tax authority in the country where they’re registered. This report includes total sales, and the VAT collected. Businesses then send the VAT payment to the same tax authority. This system makes accounting easier by consolidating payments into one report, so businesses don’t have to register in multiple countries. - Smooth Delivery to Customers
With VAT already paid, customers get their orders without any additional VAT or customs fees, making the process smoother. For businesses, this leads to more predictable and faster deliveries, which improves customer experience.
What Are the Benefits of IOSS?

Who Should Use This System?
IOSS is helpful for businesses selling goods worth up to €150 to EU customers. It’s useful for:
- E-commerce stores selling directly to EU customers, even if they are based outside the EU.
- Online marketplaces helping with cross-border sales.
- Shipping companies that manage VAT for businesses.
- Non-EU businesses wanting a simpler way to sell to EU customers.
Import One-Stop Shop vs. One-Stop Shop (OSS):
The Import One-Stop Shop applies to goods valued under €150 being imported into the EU, while the One-Stop Shop (OSS) covers goods or services being sold within the EU. The OSS system applies to businesses selling within the EU, while the Import system focuses on imports. If businesses sell both inside and outside the EU, they might use both systems to manage VAT.
Why Is IOSS This Important for Businesses?
The Import One-Stop Shop helps businesses, especially those outside the EU, by making VAT collection easier. It removes the need for businesses to register for VAT in every EU country. However, businesses must still:
- Correctly charge VAT based on the customer’s location.
- Keep records and file VAT reports on time.
- Avoid common mistakes, like using the wrong VAT rate or missing a registration number in customs forms.
For higher-value goods, businesses still need to follow traditional VAT rules.
How to Register for the IOSS:
- Choose an EU Country for Registration: Pick one EU country to register for IOSS with.
- Apply Through a Tax Authority or an Intermediary: Some businesses outside the EU may need help from an intermediary.
- Get a Registration Number: Once registered, businesses get a unique number to use in customs forms.
