If you buy a service or product from an EU country other than Finland, you can add it to bookkeeping. It will be recorded in the accounts without VAT.
Make sure you have a purchase receipt showing both your own VAT number and the seller's VAT ID. For a Finnish company, the VAT identification number consists of the country identifier FI and the business ID number, from which the line between the last two digits has been removed. For example, if the company's business ID is 1234567-8, its VAT ID is FI12345678. The format of the seller's VAT ID may vary depending on the format of the company's domestic business IDs.
Once you have verified that you have a receipt for your purchase showing the VAT IDs of both parties you can record your purchase in the UKKO system. Enter the VAT-free amount from the receipt and specify how the purchase is related to your business.
