About VatVolt

VatVolt builds free, practical VAT tools for freelancers, expats and small businesses working across Europe. EU VAT rules — reverse charge, autoliquidation, inversión del sujeto pasivo, omvänd skattskyldighet — are confusing enough in your own language, let alone in a foreign one. Our calculators turn those rules into simple questions with correct, ready-to-use invoices.

Every tool is free, needs no signup, and generates invoices with the legal wording each country's tax authority expects. Rates and rules are checked against current sources and stamped with their last-update date. Start with the tools or read the guides to understand the rules behind them.

VatVolt is an independent information project. It is not affiliated with any tax authority, and nothing here is professional tax advice — when in doubt, check with a qualified accountant.
