What information should you have ready when calling the VAT helpline?

When reaching out to the VAT helpline, having your VAT registration number and postcode readily available is crucial. The VAT registration number uniquely identifies your business within the tax system, and it helps the helpline staff quickly access your tax records and account details. Providing your postcode also helps in verifying the address associated with your business, ensuring that the service provided is accurate and efficient.

While other information such as a National Insurance number, bank account details, and company registration number may be relevant in different contexts, they are not specifically necessary for VAT inquiries. The VAT registration number and postcode are directly linked to your VAT obligations, making option B the most relevant and effective choice when seeking assistance from the VAT helpline.
