What is a VAT Registration Number?
A VAT registration number is a unique identifier assigned by HMRC to businesses registered for VAT in the UK. Businesses that exceed the VAT registration threshold of £90,000 in taxable turnover must register for VAT. However, some businesses opt for voluntary registration to benefit from reclaiming VAT on expenses.
A UK VAT number follows a standard format:
- For businesses in England, Scotland, and Wales: GB 123 4567 89 (two-letter country code followed by nine digits)
- For businesses in Northern Ireland: XI 123 4567 89
This number must appear on invoices, receipts, and tax returns to ensure legal compliance.
Why is VAT Registration Important | Help with VAT Returns
Checking if a company is VAT registered is essential for several reasons:
- Legal Compliance: Ensuring a company follows UK tax regulations prevents potential legal issues.
- Fraud Prevention: Verifying VAT numbers helps avoid scams and fraudulent transactions.
- Accurate Invoicing: A VAT-registered company must include its VAT number on invoices to charge VAT correctly.
- VAT Reclamation: If your business is VAT registered, you can reclaim VAT on purchases from other VAT-registered businesses.
- Building Business Trust: A VAT-registered company appears more credible and professional.
How to Check if a Company is VAT Registered
1. Check Invoices and Official Documents | VAT Returns Accounting in Glasgow
A legitimate VAT-registered business must include its VAT number on:
- Invoices
- Receipts
- Credit notes
- Business websites
- Contracts
If the VAT number is missing, it is a red flag that the company might not be VAT registered.
2. Use the HMRC VAT Checker
HMRC provides an online VAT number checker to verify UK VAT numbers. You can access it here:
Simply enter the VAT number, and the system will confirm if it is valid.
3. Contact the Business Directly
If you cannot find the VAT number online or on invoices, contact the business directly. Ask them to provide their VAT registration details.
4. Check the VIES VAT Database for EU Transactions
For businesses trading with the EU, use the VIES VAT number validation system (VAT Information Exchange System). It confirms VAT numbers for companies operating within the EU and Northern Ireland:
5. Call the HMRC VAT Helpline
If the above methods fail, you can call HMRC’s VAT helpline: 0300 200 3700. You will need to provide your VAT number for verification.
Do All Businesses Have VAT Numbers?
No, not all businesses have a VAT registration number. Only businesses registered for VAT receive one. If a company’s turnover is below £90,000, VAT registration is optional. However, some businesses register voluntarily to:
- Reclaim VAT on purchases
- Enhance credibility with suppliers and customers
- Prepare for future growth
Businesses that are not VAT registered cannot charge VAT on sales, which is why checking a company’s VAT status is important before making transactions.
What to Do if a VAT Number is Invalid?
If a company’s VAT number is invalid or cannot be verified:
- Double-check the number – Ensure you have entered it correctly.
- Contact the company – Ask for clarification or an updated VAT number.
- Report suspicious activity to HMRC – If you suspect fraud, report it to HMRC immediately.
When Will You Use Your VAT Registration Number?
If your business is VAT registered, your VAT number will be required for:
- Filing quarterly VAT returns
- Charging VAT on sales
- Claiming VAT refunds on purchases
- Issuing VAT invoices
- Dealing with HMRC VAT correspondence
- Registering with suppliers
- International transactions (especially in the EU)
A VAT number is crucial for tax compliance and ensuring smooth business operations.
How to Find a Business VAT Number
Finding a VAT number is easy if you follow these steps:
- Check the company’s invoices – VAT numbers are typically displayed on all official documents.
- Visit the company’s website – Many businesses list their VAT registration number on their website.
- Use HMRC’s online VAT checker – A quick and accurate way to verify VAT registration.
- Check the VIES system for EU businesses – Essential for international transactions.
- Contact the company – If you cannot find the number, reach out to them directly.
By verifying VAT numbers, you protect your business from tax errors and fraud.
What if a Company is Not VAT Registered?
If a company is not VAT registered:
- They should not charge VAT on sales.
- You cannot reclaim VAT on purchases from them.
- You might want to check if they should be VAT registered (if their turnover is over £90,000 and they haven’t registered, they may be avoiding VAT obligations).
If you frequently deal with a non-VAT-registered business, assess the financial impact of not reclaiming VAT on purchases.
