Issued and received invoices must be reported to the Slovak Financial Administration (Finanฤnรก sprรกva) within 15 days of issuance or receipt, and archived in XML format for 10 years. Non-compliant invoices prevent Slovak buyers from claiming input VAT deductions.

Within 15 days of issuance or receipt, all B2B invoices must be reported to the Slovak Financial Administration (Finanฤnรก sprรกva) once the mandate takes effect in January 2027.
From January 2027, Slovak buyers cannot claim input VAT deductions on invoices that do not comply with the mandatory structured e-invoicing format. Compliance is therefore a direct financial requirement for VAT recovery, not just a technical formality.
All electronic invoices issued and received in Slovakia must be archived in their original structured XML format (Peppol BIS 3.0 UBL 2.1) for a minimum of 10 years to satisfy Slovak tax audit standards.
