Invoice requirements (rēķina rekvizīti)

Invoice requirements (rēķina rekvizīti) are the details an invoice must contain to be a valid accounting source document and, for a VAT payer, a tax invoice. The basic set comes from Section 11 of the Accounting Law, the extra VAT details from Section 125 of the VAT Law.

Every source document needs the document type, date, number, the issuer's name and registration number or taxpayer code, details of the other party and a description of the transaction with its value in money. No signature is needed where Section 11(7) of the Accounting Law applies, for example when a contract proves the transaction.

A VAT invoice also shows the supplier's VAT number, the buyer's VAT number if it has one, the supply date if it differs from the issue date, the name, quantity and unit of the goods or services, the unit price before VAT, any discounts, the rate applied, the VAT amount and the total before VAT.

Where 0% or an exemption applies, the invoice must refer to its legal basis, such as the relevant section of the VAT Law. Where the buyer pays the VAT, it must carry the words "nodokļa apgrieztā maksāšana" (reverse charge). An invoice from a foreign supplier can be booked with fewer details if it has at least those listed in paragraph 33.1 of Cabinet Regulation No. 877.
