As eCommerce keeps expanding internationally, it’s more crucial than ever to comprehend how VAT (Value Added Tax) affects your company. Recent changes to EU VAT regulations have a direct impact on how you collect, report, and pay tax, regardless of whether you’re selling physical goods, digital goods, or through platforms like Shopify, Amazon, or Etsy.

The European Union (EU) implemented the OSS (One Stop Shop) and IOSS (Import One Stop Shop) as two essential systems to streamline VAT compliance for international commerce. These programs are intended to let online sellers manage VAT across several EU countries without having to register in each separately.

This blog will help you confidently and clearly understand VAT regulations if you’re importing low-value goods or selling to clients in the European Union (EU).

What is VAT for eCommerce?

A consumption tax known as VAT (Value Added Tax) is levied on the sale of goods and services. It is usually charged to clients at the point of sale in eCommerce, particularly when cross-border transactions are involved. Companies are in charge of collecting VAT from clients and sending it to the relevant tax office.

When selling to customers (B2C) in nations where VAT is enforced, such as the European Union, internet retailers frequently have to pay VAT. The destination country determines the tax rate, and if merchants surpass local sales thresholds, they might have to register for VAT in several countries.

Platforms such as OSS (One Stop Shop) and IOSS (Import One Stop Shop) enable vendors to report and pay VAT for several EU nations with a single registration, streamlining compliance. This makes cross-border eCommerce activities easier and eliminates the need for separate VAT registrations in every nation.

Why Do eCommerce Businesses Need It?

eCommerce companies must deal with VAT since they offer products or services in nations where it is required by law. Here is why it is important:

  • Legal Obligation: It is legally necessary for you to collect and pay VAT to the local tax authorities if you sell to clients in countries that charge VAT, such as the EU.
  • Cross-Border Sales Compliance: Complying with the tax laws of the buyer’s jurisdiction is frequently necessary when selling abroad. VAT guarantees that when you ship internationally, you are in compliance.
  • Avoid fines and penalties: Inaccurate VAT registration or reporting may lead to audits, penalties, and even marketplace bans.
  • Marketplace Requirements: To sell in some areas, websites such as Amazon, eBay, and Etsy may demand VAT numbers. If you don’t comply with these requirements, your account may be blocked.
  • Establishing Trust: Accurately displaying VAT charges on invoices at the point of sale demonstrates professionalism and fosters trust among clients, particularly among buyers.
  • Simplified VAT Schemes Are Available: You can save time and cut down on administrative work by registering for OSS or IOSS, which makes managing VAT across several nations easier.

How Does VAT Registration Work?

The process of registering with a nation’s tax office to enable your company to lawfully collect and pay Value Added Tax on sales is known as VAT registration.

Here’s how it works for eCommerce:

  • Check if You Need to Register: Necessary if you meet local sales targets and sell to clients in VAT-collecting nations.
  • Choose a Scheme: To make EU reporting easier, register in each nation or use OSS/IOSS.
  • Apply Online: Send your company’s information to the local tax office.
  • Get a VAT Number: Apply it to tax returns and invoices.
  • Start Charging VAT: Apply the appropriate VAT rate according to the customer’s nation.
  • File Returns: Regularly report sales and pay VAT (typically every quarter).

What is OSS (One-Stop Shop) and How Does it Help You?

One-Stop Shop, or OSS, is a system that streamlines VAT compliance for service providers and online retailers who sell to customers (B2C) in all EU nations.

Businesses that offer goods and some services to customers (B2C) across EU borders can find it easier to report VAT under the One Stop Shop (OSS) VAT program. You can file a single VAT return through one EU member state with OSS rather than registering for VAT in each EU nation where you conduct business.

Understanding the EU OSS VAT Scheme

Introduced in July 2021 with the intention to streamline VAT compliance across the EU, the EU OSS (one Stop Shop) VAT sceheme enables businesses to make corss-border sales, and file and pay for VAT through a single quarterly return – within their own country of registeration.

Let us understand with an example:

Imagine you are kind of a big-shot in handmade ceramic objects. Not only your home country – the UK, loves it, but also they are popular in France, Germany, Spain, and so more and so forth.

Now before 2021, you would have to register for VAT for each country you sold to. Your days would go dealing different tax authorities, navigating different rules, filing multiple returns and more. Thanks to OSS scheme, you just have to register for OSS in UK and the rest of VAT filing becomes streamlined for all countries.

How It Helps You:

  • Makes VAT compliance easier: You can stop registration in each EU nation where you sell.
  • Reduces administrative expenses and effort: One payment, one gateway, and one registration.
  • Maintains your compliance: helps guarantee that, depending on the buyer’s location, you are charging the appropriate VAT rate.
  • Enhances the client experience: There are no unexpected costs for your clients because prices are transparent and include local VAT.

How to Register for OSS?

Registering for the OSS scheme is a straightforward process and can be done online through your local tax authority in the EU country where your business is established.

Step-by-Step Guide

  • Go to Your National Tax Portal: Go to your local tax authority’s official website (for example, in France, Germany, Spain, etc.).
  • Log In to Your Business Account: Use your business tax credentials to access the portal.
  • Select the OSS Registration Option: Look for “Union OSS” if your company is headquartered in the EU and sells to EU customers.
  • If you’re a non-EU company offering digital services to EU clients, choose “Non-Union OSS”.
  • Provide Required Details:
    • Business name and address
    • VAT number
    • Contact person
    • Types of goods/services sold
    • Countries you sell to within the EU
  • Submit the Registration Form: Following submission, you will receive a confirmation (and, if relevant, a unique OSS VAT ID).
  • Start Filing Quarterly OSS Returns: Even if no sales were made, you still have to file VAT reports every quarter after you’re registered.

What is IOSS VAT and Who Should Use It?

An EU system known as IOSS (Import One-Stop Shop) enables vendors to gather, record, and pay VAT on low-value items (valued at €150 or less) that are imported into the EU and subsequently sold to customers. It makes VAT compliance easier by enabling companies to manage all VAT through a single interface, saving customers from unpleasant surprises or delays at customs.

How does IOSS help with Low-Value Sales to the EU?

  • VAT collection during checkout → Clients pay the entire amount up front, with no additional fees due at delivery.
  • Avoid customs delays→Customs delays can be avoided because packages clear customs more quickly because VAT is pre-paid.
  • Reducing administrative burden → Rather than registering in various EU nations, sellers now just need to file one monthly VAT return through a single IOSS registration.
  • Enhancing client happiness → Clear pricing and speedier delivery boost customer confidence.

A bit tough to grasp? Let us understand with an example

Meet Alex, an aspiring entrepreneur who sells phone cases under €150 to EU customers (which is around £130 for UK clients). When he shipped to Maria, a customer in Spain- she thought she just has to pay the value of €20 at checkout. Unexpectedly she was met with a startle, as the delivery company demanded extra VAT charges and customs processing fees.

Though it was not Alex’s fault, she felt misled. Such was the case before July 2021. Now after the EU introduced the Import One Stop Shop (IOSS) scheme, Maria can see the full pricing including EU VAT right on the website. Her goods are shipped faster with fewer hold-ups. As for Alex – he now has to file only one monthly VAT return. Both the sellers and customers are happy.

How to Register for IOSS?

  • Determine Eligibility:
    • You offer products to customers in the EU that cost €150 or less.
    • You sell products online to customers in the EU, with each item priced at €150 or less. Your business may be based either within the EU or in a non-EU country.
  • Choose a Country to Register In: EU companies use their national tax site to register in their nation. Businesses outside of the EU are required to designate an intermediary based in the EU to register on their behalf.
  • Visit the Tax Authority Portal: Visit the EU nation’s official tax website to complete the registration process. Find the section labeled “IOSS Registration.”
  • Submit Registration Application:
    • Business details (name, address, tax ID)
    • Description of goods/services
    • EU countries you sell to
    • Details of your appointed intermediary (if non-EU)
  • Receive Your IOSS Identification Number: After being accepted, you will receive a special IOSS VAT ID that you need to include on invoices and customs paperwork.
  • Start Using IOSS: VAT is charged at the point of sale. Submit monthly IOSS VAT returns to the nation in which you are registered. Send the VAT collected all at once.

What’s the difference between OSS and IOSS?

The OSS (One Stop Shop) is for businesses based in the EU selling goods or digital services to customers in other EU countries. It lets them report and pay VAT in just one country, even if they sell across the EU.

The IOSS (Import One Stop Shop) is for sellers outside the EU (like in the UK or US) who sell low-value goods (under €150) to EU customers. It lets these sellers collect VAT at the time of purchase and file it through a single monthly return, avoiding delays at customs.

What goods are excluded from IOSS?

OSS only applies to low-value goods (under €150) that are sold directly to EU consumers. It does not apply to:
– Goods over €150
– Excise products like alcohol or tobacco
– B2B transactions (sales to businesses with a VAT number)

How often do I need to file OSS or IOSS VAT returns?

– OSS returns are filed every quarter (four times a year).
– IOSS returns must be filed monthly (twelve times a year).

Can I use IOSS for EU-to-EU sales?

No. IOSS is only for non-EU sellers sending low-value goods to the EU.

Is shipping cost included in the €150 IOSS threshold?

Yes, shipping and insurance costs are included in the €150 IOSS threshold (if charged to the customer and included in the customs value).If the total value of the order exceeds €150, IOSS cannot be used, and the customer has to pay import VAT and possible custom duties at delivery.
