On 21 August 2026, Slovakia’s Financial Administration (FRSR) confirmed that its e-invoicing and e-reporting infrastructure is fully operational – marking a key milestone ahead of the planned January 2027 mandate.
The mandate requires mandatory e-invoicing and real-time reporting obligations for domestic business-to-business (B2B) and business-to-government (B2G) transactions. In 2030, the mandate will also expand to intra-community EU transactions, aligning with the EU’s VAT in the Digital Age (ViDA) legislation.
A draft amendment to the VAT Act proposes a grace period in the first quarter of 2027 and would postpone the buyer-side digital reporting obligation until the full mandate takes effect in July 2030. The amendment is still pending parliamentary approval.
What this means for businesses
Slovakia’s voluntary adoption window runs from 1 January 2026 through 31 December 2026. With this window closing and the mandate approaching fast, businesses operating in Slovakia should use the time to test their e-invoicing setup, confirm integration requirements, and validate data quality before the 2027 deadline.
