Do Amazon, Shopify or Etsy Handle IOSS for You?

Do Amazon, Shopify or Etsy Handle IOSS for You?

One of the most common questions ecommerce businesses ask is:

“Doesn’t Amazon/Shopify/Etsy deal with all of this already?”

And the honest answer is:

…sometimes.

The tricky part is that responsibility depends on how your ecommerce setup actually works.

Do Marketplaces Handle VAT?

In some situations, yes.

Certain online marketplaces are classed as a “deemed supplier” under EU VAT rules.

This means the platform may collect and pay VAT on specific transactions.

However, that does not automatically mean:

• You have no VAT responsibilities
• You don’t need registrations
• You can ignore IOSS entirely

What About Amazon?

Amazon may handle VAT on some EU sales, particularly where:

• Goods are imported into the EU
• Certain B2C transactions apply
• Amazon is treated as the deemed supplier

But businesses still need to consider:

• Where stock is stored
• Whether local VAT registrations are required
• Which sales Amazon is actually covering

If you use FBA, stock locations alone can create additional VAT obligations.

What About Shopify?

Shopify provides tools to help you calculate and charge VAT — but it does not take on your VAT responsibility.

In simple terms:

• Shopify gives you the tools
• You are still responsible for using them correctly

That means ecommerce businesses still need to:

• Configure VAT settings properly
• Understand where VAT applies
• Decide whether IOSS is needed

What About Etsy?

Etsy may collect VAT on certain transactions, particularly low-value imports into the EU.

But sellers still need to be aware of:

• Which transactions Etsy covers
• Whether they sell on other platforms too
• Whether additional VAT obligations exist elsewhere

Multi-channel sellers are especially at risk of assuming everything is covered when it isn’t.

Why Ecommerce Businesses Get Caught Out

A very common pattern we see is:

“We thought the platform handled it.”

Then later discovering:

• VAT was only partially covered
• Their own website wasn’t compliant
• Stock storage triggered extra obligations
• IOSS wasn’t being applied correctly

That’s usually when customs or tax letters arrive.

What Should You Check?

If you sell into the EU, it’s worth reviewing:

• Which platform handles VAT (if any)
• Whether you use multiple sales channels
• Where your stock is physically stored
• Whether checkout VAT settings are correct
• Whether IOSS applies to your setup

Most issues come from assumptions, not intent.
