Tax and invoicing
First Day Online is a service provided from Spain, a member state of the European Union. Which tax rules apply depends on your status:
- Business customers with a valid EU VAT number: the invoice is issued without VAT. The reverse-charge mechanism applies, so you account for the VAT yourself in your own country.
- Private customers, or businesses without a valid EU VAT number: Spanish VAT applies under the rules in force. Prices are shown excluding tax. Tax added at checkout where it applies.
