VATCalc combines artificial intelligence with its legislative-coded tax engine to simplify global VAT compliance, from implementation and data mapping through to VAT determination, e-invoicing and reporting.
AI interprets data, identifies issues and automates workflows. VATCalc’s deterministic tax engine applies the legislation, ensuring consistent, explainable and auditable VAT outcomes.
AI makes compliance easier. VATCalc gets the tax right.

VATCalc Copilot is a natural language interface to our platform
Instead of learning menus, screens and workflows, simply tell Copilot what you want to achieve

We’ve added VATCalc Copilot to our platform, the first agentic Artificial Intelligence assistant built directly into VAT determination, returns, audits and workflows
It doesn’t just answer questions like a typical chatbot.
Instead, Copilot has controlled access to your data, VATCalc’s tax engine, reporting, e-invoicing and platform capabilities.
It retrieves live VAT returns, tasks, audit results and company information, invokes VAT determinations, and takes you directly to the information or workflow you need.
So, rather than asking AI to “know” VAT, we’ve taught it how to use VATCalc.
Real-time item classification for VAT calculations, e-invoicing, Accounts Payable processing and VAT return submissions

Correct VAT starts with knowing what is actually being supplied.
But ERP data, supplier invoices and product catalogues rarely arrive neatly classified for indirect tax. Descriptions can be technical, abbreviated or ambiguous. Traditionally, tax teams have had to map products manually or build rules around vendors, GL accounts, projects and cost centres.
AI Mapping Studio: faster implementation, less manual data preparation
One of the biggest costs in implementing VAT automation isn’t configuring tax rules. It’s mapping customer transaction data.
Mapping translates each customer’s unique ERP export into the standard data structure needed for automated VAT determination and reporting.
Many software vendors and advisory firms, including the Big Four, are introducing AI-powered mapping tools. But most stop once the data has been mapped.

Watch AI produce VAT advice on complex, cross-border transactions
You can now use our VAT Advisor product, based on our global tax engine, to produce tax advice to review, edit and share with colleagues, customers and counterparties. This helps ensure you can all agree on the correct transaction tax treatment, including:
