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.

Start every day knowing exactly what needs your attention
“Which of my outstanding tasks are most urgent, risking fines or other issues?”

Copilot brings together your assigned tasks, upcoming filings and overdue work into a single view, helping you prioritise what matters without searching across multiple screens.
Need to refine the results? Just continue the conversation:
- “Show me all filings due in the next 14 days.”
- “Now just the overdue ones.”
- “Only show Austrian filings.”
- “Any e-reporting submissions missing from filings?”
Find VAT returns in seconds – focus on risk
Whether you’re looking for returns due this month, overdue Belgian filings or high-risk returns awaiting review, Copilot retrieves the information instantly.
- “Show me all the VAT returns due this month.”
- “Now ones assigned to me”
- “Show me the high-value filings I’m reviewing.”
- “What’s the risk score for that Spanish return?”
- “Are all KSeF e-invoices included in Polish VAT return?”
Results are presented in interactive tables, allowing you to open the underlying VAT return with a single click.
If you simply want to check the headline figures before opening the return, Copilot can also provide a filing preview.

Interrogate your VAT data

Copilot doesn’t just retrieve data—it helps you understand it.
- “Show me a summary of audit errors for the last 30 days.”
- “Which upload batches do I have?”
- “Break down the ‘Exports’ errors for me.”
- “Download a sample of those error transactions.”
Because Copilot understands the context of your conversation, you can continue refining your questions without starting again.
Why Copilot is different
Most AI assistants explain VAT. Copilot uses VATCalc.
Behind every conversation is an orchestration layer that securely connects natural language to VATCalc’s tax engine and application services.
The AI understands what you’re trying to achieve.
VATCalc performs the tax and compliance work.
Rather than asking AI to “know” VAT, we’ve taught it how to use VATCalc. The large language model interprets your request, while VATCalc retrieves the live data, invokes the appropriate application service or performs the VAT determination before presenting the results back in plain English.
That allows us to combine the flexibility of conversational AI with the reliability of VATCalc’s proven legislative content, tax engine and compliance workflows.
Enterprise-ready from day one
The first production release has deliberately been designed as read-only.
Copilot can retrieve filings, preview returns, review audit data, locate companies and perform VAT determinations.
It cannot edit records, submit returns or change workflows.
Every request runs under your existing permissions and only within your own tenant, ensuring users only ever see information they are already authorised to access.
