Who is in scope

Taxpayers with seat or residence in Croatia. Foreign suppliers without Croatian establishment and outbound cross-border invoices are out of scope. Ongoing duties: issuer fiscalises in real time; BUYER must fiscalise within 5 working days of receipt; monthly reporting of payments received (by the 20th), of undelivered invoices where the directory lookup failed, and of rejected invoices. VAT return deadline moved to the last day of the following month.

Key dates

  • 1 Sep 2025 Fiscalization Act (Official Gazette 89/2025) in force; voluntary test environment opens, no penalties.
  • 1 Jan 2026 Mandatory: all Croatian-established VAT-registered taxpayers issue, receive and fiscalise e-invoices for domestic B2B and B2G. Non-VAT taxpayers must be able to receive.
  • 1 Jan 2026 B2C fiscalisation extended to all payment methods, not just cash.
  • 1 Jan 2027 Non-VAT taxpayers (small traders, paušalisti, OPG) and public bodies must also issue.
What practitioners get burned by

No grace period — enforcement ran from day one, with fines reported in the EUR 2,650–66,360 range for legal entities. The two requirements foreign-owned groups most often miss are the buyer-side 5-working-day fiscalisation duty and the mandatory 6-digit KPD 2025 product classification codes.
