Free VAT Tools for EU Businesses

Access a set of free VAT tools built on the same engine as VIESAC: validate EU VAT numbers via VIES, calculate VAT and gross price, check if the reverse charge mechanism applies and look up standard and reduced VAT rates across EU member states.

Step 1 · Validate VAT

EU VAT Number Validator (VIES)

Validate EU VAT numbers against the official VIES system before you issue invoices or approve 0% VAT for intra‑EU B2B supplies. Get a quick VALID / INVALID status for VAT IDs in all EU member states.

EU VAT Validator

Ideal for first‑line VAT number checks before onboarding customers or applying VAT exemption.

Step 2 · Check amounts

EU VAT Calculator — Net, VAT & Gross

Calculate VAT amount and gross price from a net price for any EU country using standard VAT rates and local VAT abbreviations (MwSt, TVA, IVA, BTW). Perfect for quick invoice and quote checks.

VAT Calculator

Use as a quick EU VAT calculator when reviewing invoices, pricing scenarios or reverse charge cases.

Step 3 · Reverse charge

Reverse Charge Checker — 0% VAT

See if the EU reverse charge mechanism is likely to apply for a cross‑border B2B transaction. Compare seller and buyer countries and transaction type to understand when 0% VAT on the invoice is appropriate.

Reverse Charge Checker

Helpful when deciding if reverse charge applies and which VAT rate should appear on the invoice.

Step 4 · VAT rates

VAT Rate Finder — Standard & Reduced Rates

Quickly see standard and reduced VAT rates for EU countries. Reference typical VAT percentages when checking invoices or configuring tax rules in your invoicing, ERP or ecommerce systems.

VAT Rate Finder

Use as a quick VAT rate reference for standard and reduced rates maintained in your VIESAC account.

How these free VAT tools fit into your compliance workflow

Start with the EU VAT Number Validator to confirm that your customer has a valid EU VAT number in VIES. Use the VAT Calculator to check the VAT amount and gross price for the country‑specific VAT rate. When you sell cross‑border B2B, the Reverse Charge Checker helps you understand if 0% VAT and reverse charge are likely to apply. Finally, the VAT Rate Finder gives you a quick view of standard and reduced VAT rates per country.

All tools are designed as convenient entry points into VIESAC. For full audit trails, certificates and long‑term storage of your VAT checks, you can create a free VIESAC account and connect these workflows with your invoicing and ERP systems.
