Frequently Asked Questions
Quick answers about our VAT tools and data.
How do I add or remove VAT?
Use VAT Calculator to add VAT to a net price or remove VAT from a gross price. Enter the amount and VAT rate to get net, gross and VAT values instantly.
What is the Reverse VAT Calculator?
It helps you remove VAT from a VAT-inclusive price. Enter the total (gross) and the VAT rate to calculate the net price and VAT amount.
Where do your VAT rates come from?
VAT rates are sourced from official authorities such as the European Commission VAT database and HMRC. We aim to keep them up to date for 2025.
Can I validate VAT numbers?
Yes. Our VAT Number Check supports UK and EU formats. When available, we use official services (e.g., EU VIES) to help verify validity.
What is the UK VAT Threshold Checker?
It estimates whether your rolling 12‑month turnover exceeds the UK VAT registration threshold (£90,000). Always confirm with HMRC or an accountant.
Are results guaranteed to be accurate?
We strive for accuracy but provide results for general guidance only. Always verify with official sources or professionals for compliance‑critical decisions.
Do you store the numbers I enter?
No. Inputs to our calculators are processed in real time and are not stored on our servers. See our Privacy Policy for details.
Which countries are supported?
We support UK, EU and many worldwide VAT rates. Some features, like VAT number validation, focus on UK and EU formats.
Can I use the invoice template for my business?
Yes. The Invoice Generator helps create VAT‑aware invoice templates. Always adapt fields to your local requirements and consult your accountant if needed.
