Proposal underway: VAT reporting amendments & e-invoicing tweaks
Croatia moves to fine-tune Fiscalization 2.0. The government proposes changes to the VAT Law to align e-invoicing rules with VAT reporting cycles and simplify administration. Public consultation is open, and adoption is expected before year-end.
The start date stays firm: January 2026. Businesses now need to check how these adjustments affect invoice data flows and reporting processes.
