What is a VAT Number and Why Do You Need One? (EU & UK)

What is a VAT Number and Why Do You Need One? (EU & UK)

Overview

  1. A VAT number (Value Added Tax number) is a unique identifier issued by a tax authority to businesses that are registered to collect and pay VAT (Value Added Tax).
  2. VAT is a consumption tax applied to most goods and services sold in the EU and UK.
  3. Vat registration is a legal requirement - As a seller, you don’t want to be hit with hefty fines and legal issues, as tax authorities impose significant penalties on businesses that fail to register for VAT when required. These fines can accumulate quickly, especially if the oversight continues for an extended period.
  4. Operating without a VAT number in countries where it is mandatory is illegal. This can lead to legal actions against your business, including potential criminal charges.

Why do you need a VAT number?

If you are selling into the EU or UK, a VAT number is essential for legal trading, tax compliance, and marketplace operations.
You will typically need a VAT number to:
1. Charge and Collect VAT
You must charge VAT on applicable sales and report this to the relevant tax authority (e.g. HM Revenue & Customs in the UK).
2. Import Goods into the EU or UK
If you are shipping goods into these regions, a VAT number is often required to:
  1. Clear customs
  2. Pay import VAT
  3. Act as the importer of record
Without it, your goods may be delayed or held at the border.
3. Sell on Online Marketplaces
Most major platforms—such as Amazon, eBay, and Shopify—require VAT details to:
  1. List products in certain regions
  2. Remain compliant with local tax laws
  3. Avoid account restrictions
4. Store Inventory in the EU or UK
  1. If you use fulfilment centres (e.g. Amazon FBA or third-party logistics providers), you will need a VAT number in the country where your stock is stored.
5. Reclaim VAT on Business Costs
With a VAT number, you may be able to reclaim VAT paid on:
  1. Imports
  2. Supplier invoices
  3. Logistics and fulfilment services

When do you need to register?

You may need to register for VAT if you:
  1. Are based outside the EU or UK and selling into these regions
  2. Import goods into the EU or UK
  3. Store inventory in an EU or UK warehouse
  4. Exceed distance selling thresholds (EU) or meet UK VAT obligations
  5. Sell directly to consumers (B2C)
In the EU, you may also use schemes like the One-Stop Shop (OSS) to simplify VAT reporting across multiple countries.

EU vs UK VAT – What’s the difference?

Since Brexit, the EU and UK operate separate VAT systems:
UK VAT: Managed by HM Revenue & Customs
EU VAT: Managed individually by each EU Member State
This means:
  1. You may need multiple VAT registrations in the EU
  2. You may also need a separate UK VAT number

What happens if you don’t have a VAT number?

If required and not obtained, you may face:
  1. Shipment delays or customs holds - this can result in fines that amount to £100's per day that the goods are held
  2. Marketplace listing restrictions and inability to sell your products in the region
  3. Financial penalties or backdated tax liabilities
  4. Inability to legally sell in certain regions

To summarise

A VAT number is essential for selling goods in the EU and UK. It ensures you can import products, sell through marketplaces, remain compliant with tax laws, and avoid costly disruptions.
