Any registered business can register for the IOSS through an EU-based IOSS intermediary. Businesses in the EU can register for the IOSS directly, or through an IOSS intermediary.

The most talked about EU VAT scheme is by far the IOSS. The IOSS allows for a simplified customs process and collection of VAT at the time of sale for goods delivered from outside of the EU.

The IOSS registration process depends on whether your company is registered in the EU or not. For an EU company it is a very straightforward process: go to your national tax administration online portal (yes, they all have it), login in, and find the place to register for the IOSS. Should take less than 10 minutes. In digitally advanced countries you will receive the IOSS number immediately, in some by mail.

For a non-EU company, the process looks very different. They will need an Intermediary to handle the IOSS registration. The IOSS number is as much the Intermediary’s as it is the online merchant’s as they are also responsible for the reporting and payment of VAT. This is also why most charge a hefty starting fee for the service. For non-EU companies, the registration country can be chosen by the Intermediary.

Mind you, you have to really be mindful about who and where you disclose the IOSS number: misuse is rampant and can result in you being responsible for someone else’s VAT. And once you register for the IOSS, also zero reports have to be filed.

Because we at EAS believe in automating the difficult, we don’t have to charge you for the IOSS registration or monthly filing. The shipments have to all go through our SaaS for full, credible compliance. Shipments can also be manually entered into the SaaS if they are placed by phone or email. This results in a stress-free, cost-efficient way to handle the scary international compliance.

7. What does IOSS registered mean?

Being IOSS registered means the company can utilise the lighter customs process in EU customs and collect VAT at checkout. It also means a liability to report and pay VAT monthly to the country of registration.

IOSS number tells the customs that there is a VAT liable company somewhere and that they don’t have to collect VAT on the shipment as it will be reported and paid.

It is basically a facilitator for a faster, more cost-efficient delivery and better customer service via single action purchase.

FAQ

What is the additional transaction fee?

The additional transaction fee only applies if you exceed the number of orders included in your EAS plan. The fee is charged only for the orders beyond your plan’s monthly limit.

For example, the IOSS Starter Plan includes 15 IOSS orders per month. If you receive more than 15 orders in a month, a €1.50 fee is applied for each additional order starting from the 16th order onward.

What is the Free online store configuration?

EAS configures your online store to support correct European VAT handling. This includes setting up tax rules, checkout behaviour, and data transmission to ensure compliance.

We provide this configuration service free of charge for natively supported platforms: Shopify, WooCommerce, Wix, and Shopware.

Can I add multiple stores to my EAS account?

Yes, you can connect unlimited stores to your EAS account at no extra cost.

Each IOSS plan includes a set number of free store configurations, where EAS handles the setup of EU tax settings for your online store(s):

Starter – 1 free configuration
Basic – 3 free configurations
Advanced – 4 free configurations
Plus – 5 free configurations
XL – 10 free configurations

If you’d like EAS to configure additional stores beyond what your plan includes, we offer this service for €59 per store.

You can also configure additional stores yourself using our free setup guides, available in the EAS Knowledge Centre.

How can I change my IOSS Plan?

Yes, you can upgrade or downgrade your EAS IOSS plan at any time directly from the EAS Dashboard.

Just log in, navigate to the Pricing section, and choose the plan that fits your current needs. If you make the change before the 25th of the month, the new plan will take effect from the beginning of the following month

What is the IOSS Cancellation Policy?

EAS follows the guidelines set by the European Commission and EU Member State Tax Authorities. When you cancel your IOSS service, we are still required to submit reports for the cancellation month plus the following two full calendar months.

For example, if you cancel on 15 January, we must report for January, February, and March. Your IOSS number will remain active during this time, and EAS will continue to submit the necessary filings until the end of the final reporting period.

Can I use EAS IOSS with Custom Built online store?

Yes, you can. EAS supports custom-built stores through two flexible options.

You can integrate directly via our API for full automation, or if you’re on the IOSS Basic Plan or higher, you can submit your EU sales data using a simple CSV file in the EAS reporting format.

Whichever method you choose, we make it easy to stay compliant and submit accurate reports on time.

What’s the difference between Standard, Premium, and High Priority Support?

All EAS plans come with Standard Support to help you stay compliant. If you’re on the Plus or XL plan, you automatically receive Premium Support, which includes faster onboarding and access to a prioritised support channel.

If you need the fastest response times, dedicated fastlane access, and extended support coverage, you can upgrade to the EAS High Priority Support Package for €149/month. This is our top-tier support option and is available to all customers as an add-on, regardless of your plan.

When are IOSS service fees and taxes invoiced, and what payment methods are available?

The IOSS reporting period always covers full calendar months. At the beginning of each month, we invoice the EAS service fees along with the EU taxes you’ve collected during the previous month.

You can pay via Card Payment, Bank Invoicing, or PayPal, with standard processing fees applied. Additional payment methods are being introduced continuously to give you even more flexibility.

9. Is IOSS number the same as VAT number?

No, the IOSS number is not the same as VAT number. The IOSS allows suppliers selling imported goods to buyers in the EU to collect, declare and pay the VAT to the tax authorities, instead of making the buyer pay the VAT at the moment the goods are imported into the EU

IOSS is a unique number impossible to deduct from any other identifier due to its exposure to risks.

10. Is IOSS compulsory?

No, IOSS is not obligatory.

We do recommend it, however, if your goods fall under the 150€ threshold. Nothing wrong with faster and cheaper delivery and an easier shopping experience for customers.

11. What happens if I don’t register for IOSS?

If you don’t register for IOSS, your customers pay the VAT at the moment the goods are imported into the EU. It causes delays at customs, unexpected handling fees and an unpleasant customer experience.

If you are not registered for IOSS, you cannot take advantage of the simplified IOSS scheme.

Your deliveries cost more, take longer time and can require post-purchase actions from your customers.

12. What are the benefits of IOSS?

Better customer experience
VAT can be charged at checkout, not at arrival
Lower delivery fees
Faster deliveries
Postal delivery possible
No post-purchase actions are required from your customers

13. Does IOSS include shipping costs?

IOSS does not include shipping costs.

IOSS 150€ threshold is calculated from the zero VAT without shipping or other fees.

14. Do I need to be VAT registered to sell in EU?

No, you don’t need VAT registration to sell to the EU.

If you are located outside of the EU, IOSS registration is highly recommended. VAT registration is not required for IOSS registration.

You have to have a company registered in your country, also a sole entrepreneur or similar is sufficient.

As a non-EU company you can, have a VAT registration in the EU, but before you begin stocking goods in the EU you are not obligated to do so.

15. Can I have IOSS registration in UK?

After Brexit, no you can’t.

16. How do I register for IOSS in UK?

You cannot register for IOSS in the UK, you register for IOSS in an EU country

Remember Brexit?

Talk to EAS. We have hundreds of companies from the UK registered for IOSS.

17. What is an IOSS intermediary?

IOSS intermediary acts on behalf of its clients in order to perform all reports and VAT payments to the EU tax authorities.

If businesses are not based in the EU, they need to appoint an EU-established intermediary to fulfil their VAT obligations under IOSS.

18. What to concern about IOSS number?

If you get a random IOSS number from the internet, you will be able to get the goods through the customs and someone else VAT liable – until your tax fraud will be caught and you will be banned from selling to EU. The EU customs collect data on IOSS numbers and tax administrations and then compare the IOSS reporting data.

“Borrowing” IOSS number is also common while being specifically forbidden. The process goes as follows: A party along the delivery chain has registered themselves for IOSS. They insert the IOSS number into the shipping data and collect VAT due from the merchant. The reason why this is specifically forbidden is that the value data is falsified more often than not. In addition, seller data is wrong and does not serve the purpose. A very temporary solution and more expensive than actually being compliant with EAS.
