Who this affects

Slovak businesses preparing for the mandatory B2B and B2G eFaktura regime, and the certified delivery service providers listed on the Financial Administration website.

What to do

The change

On 21 August 2026 the Slovak Financial Administration announced that the state eFaktura communication infrastructure is complete and fully operational, enabling automated transmission of invoice tax data without separate manual transcription. Full-value eFaktury can now be exchanged through certified delivery service providers listed on the Financial Administration website. The infrastructure is live for voluntary use during the transition period that precedes Slovakia's mandatory B2B and B2G eFaktura regime.

What it means

Voluntary use is the cheap window. Once the mandate starts, a failed integration is a compliance failure; right now it is a test result. The infrastructure supports automated transmission of invoice tax data without separate manual transcription, which is the part worth proving out before it is compulsory.
