## Timeline

Current and upcoming regulation for Slovakia.

<Update label="Now" tags={["B2B", "B2G"]}>
  **Voluntary transition period**<br />
  Throughout 2026, businesses can voluntarily send e-invoices through a digital postman, if their buyer also has one. The Financial Administration continues to certify digital postmen and publishes the list on its portal. E-invoicing and reporting become mandatory for domestic B2B and B2G transactions on 1 January 2027.
