Executive Summary
Many foreign businesses trading in the UK incorrectly assume they can rely on the standard UK VAT registration threshold of £90,000. In reality, overseas businesses often have to register for UK VAT from their first taxable sale.
Whether you are importing goods, operating an ecommerce business, storing inventory in the UK or selling through a UK subsidiary, understanding your VAT obligations is essential to avoid penalties, unexpected tax liabilities and disruption to your operations.
This guide explains when foreign companies must register for UK VAT, the most common compliance mistakes and the practical steps needed to remain compliant in 2026.
When Does a Foreign Business Need to Register for UK VAT?
A foreign business may need UK VAT registration if it:
- Imports goods into the UK.
- Stores inventory in a UK warehouse.
- Sells goods located in the UK.
- Makes taxable supplies in the UK.
- Operates through fulfilment centres such as Amazon FBA.
- Carries out certain construction or property-related activities.
VAT Registration Thresholds
| Business Type | VAT Registration Threshold |
| UK-established business | £90,000 |
| Overseas business (NETP) | £NIL (they most registered regardless of the number of sales. |
A Non-Established Taxable Person (NETP) is a business that is not established in the UK but makes taxable supplies in the UK. In many cases, registration is required immediately rather than once a turnover threshold is reached.
Common Scenarios Requiring VAT Registration
Ecommerce Businesses
A US company storing products in a UK fulfilment centre and selling through Shopify or Amazon will generally require UK VAT registration before trading begins.
Importing Goods
A foreign company importing products into the UK as importer of record will often need a VAT number to recover import VAT and comply with HMRC requirements.
International Group Structures
Many groups assume their UK subsidiary covers all VAT obligations. However, VAT registration applies to the entity making the sale, importing the goods or owning the inventory.
Most Common VAT Compliance Mistakes
1. Assuming the £90,000 Threshold Applies
This is the most frequent error made by overseas businesses and often results in late registrations. There is no threshold for overseas entities trading in the UK.
2. Registering Too Late
HMRC can backdate VAT registrations and assess VAT on historic sales, even if VAT was not charged to customers.
3. Incorrect Import Procedures
Common issues include:
- Wrong importer of record.
- Missing customs documentation.
- Failure to use Postponed VAT Accounting correctly.
4. Recovering VAT Without Valid Evidence
HMRC requires proper VAT invoices and import documentation to support VAT recovery claims.
5. Poor Record Keeping
Under Making Tax Digital (MTD), businesses must maintain digital VAT records and submit VAT returns electronically.
Risks and Penalties
Failure to comply can result in:
- Backdated VAT liabilities.
- Interest charges.
- Financial penalties.
- HMRC investigations.
- Delays during audits, fundraising or business sales.
A foreign business that discovers a VAT issue after several years may face a substantial liability that cannot be recovered from customers.
Practical Example
A US ecommerce company imports products into the UK and stores them in a Birmingham warehouse before selling to UK consumers.
The company:
✓ Requires UK VAT registration.
✓ Must submit VAT returns.
✓ Must maintain digital records.
✓ May reclaim import VAT if compliant documentation is retained.
Without registration, HMRC could assess VAT on historic sales and impose penalties.
