If you’re running a business that sells goods or services in the UK—even as a overseas company—you’ve probably asked yourself: how to apply for a UK VAT number? 🤔 The process may look complicated at first, but once you know the requirements and steps, it becomes much easier.

For international businesses, applying for a UK VAT number is not only about tax compliance—it also improves credibility with customers and partners. Many companies also combine VAT registration with opening a CBiBank corporate account, which helps manage VAT payments, refunds, and global transactions efficiently.

Let’s go through the process step by step.

1. What Is a UK VAT Number?

A UK VAT (Value Added Tax) number is a unique identifier issued by HMRC (Her Majesty’s Revenue and Customs). It allows businesses to charge, collect, and remit VAT on taxable goods and services.

Format: GB followed by nine digits (e.g., GB123456789)

Purpose: To comply with UK tax law and operate legally in the market

⚠️ Reminder: Even foreign businesses may need a VAT number if they sell to UK customers.

2. Who Needs to Apply for a UK VAT Number?

You must register if:

Your UK sales exceed £85,000 in a rolling 12-month period.

You expect to exceed that threshold in the next 30 days.

You are a non-UK business selling goods or services into the UK.

You sell through platforms like Amazon UK or eBay UK.

💡 Many overseas sellers pair VAT registration with a CBiBank account, so they can collect revenues from marketplaces and handle VAT settlements seamlessly.

3. Documents Required for UK VAT Application

When applying, HMRC usually requires:

Company registration documents (e.g., certificate of incorporation)

Articles of association

Evidence of business activities (contracts, invoices, or service agreements)

Identification documents for directors/shareholders

Bank details for payments/refunds (a CBiBank corporate account is commonly used here because of its multi-currency support)

5. Common Challenges and Mistakes to Avoid

⚠️ Incomplete Applications: Missing details delay approval.

⚠️ Late Registration: Can lead to fines and backdated VAT liability.

⚠️ Banking Problems: Many UK banks reject overseas companies, which is why CBiBank is often chosen for cross-border sellers.

⚠️ Ignoring VAT Rules: Even without a UK office, selling into the UK still requires compliance.

6. After Receiving Your UK VAT Number

Once registered, you must:

Charge VAT on taxable sales.

Submit quarterly VAT returns to HMRC.

💡 Many businesses use CBiBank corporate accounts for VAT returns, payroll, and supplier payments since it supports multi-currency transfers and fast settlements.
