E-Invoicing in Finland

In Finland, starting April 1, 2021, based on the e-invoicing act (241/2019) and the implemented European standard 2014/55/EU, all invoices issued to the government must comply with standards for electronic invoicing. 

Invoice formats accepted in Finland are Finvoice 3.0 and TEAPPSXML 3.0. As part of the process of electronic invoice exchange, data on the invoice is validated in relation to the European Standard EN16931.
