Tax and VAT
Whether a business is registered for VAT decides what goes on the invoice. The answer sits in the Financial Administration registers and, for cross-border trade, in VIES.
Three types of registration
Slovak law distinguishes ordinary VAT payers, entities registered under section 7 and section 7a of the VAT Act. They are three different registers with different consequences for the invoice, and confusing them is a common source of errors.
FirmAPI returns all three plus the registration and deregistration dates, so you can tell what applied on any given day, not just today.
Domestic and cross-border
For a Slovak counterparty the Financial Administration registers are the source of truth. For a customer in another member state you need VIES, the only place that confirms an EU VAT number is valid.
