Regulations

Fiscalization 2.0 in PANTHEON

Fiscalization 2.0 is Croatia's new system for exchanging e-invoices between businesses and for fiscalizing invoices, in effect from 1 January 2026. For PANTHEON ERP users, this means setting up e-invoicing through an information intermediary (e-invoicing service provider), fiscalizing issued and received invoices, and e-reporting (eIzvještavanje) on payments.

What changes from 2026

  • E-invoices are mandatory in domestic transactions between VAT-registered taxpayers, for both issuing and receiving.
  • E-invoices are fiscalized too: the software extracts data from the e-invoice and sends a fiscalization message to the Croatian Tax Administration.
  • E-reporting (eIzvještavanje): data on invoice payments is submitted to the Croatian Tax Administration through the system.
  • Information intermediaries connect your PANTHEON to the e-invoice exchange, and the Croatian Tax Administration offers the free FiskAplikacija for reviewing fiscalized data and invoice status.

What to set up in PANTHEON

  1. VATEX texts and VAT categories in the tax code register.
  2. The e-invoice type and business process on the documents you use.
  3. The personal identification number (OIB) of each user (clerk) who issues fiscalized invoices.
  4. Fiscal counters by year.
  5. Current workflows (WF) for your chosen information intermediary.

We publish detailed step-by-step instructions with screenshots in our news.

How we can help

We check your PANTHEON settings, align registers and documents, connect the intermediary, and go through the first month of e-reporting together with you. See also the e-invoicing page.

Frequently asked questions

When does Fiscalization 2.0 take effect?

On 1 January 2026. From then on, VAT-registered taxpayers must issue and receive e-invoices, and taxpayers outside the VAT system must receive them. From 1 January 2027, taxpayers that only received e-invoices in 2026 must also start issuing them.

Are paper invoices between companies still valid?

In domestic transactions between taxpayers, a paper invoice is no longer considered valid, except in exceptional cases defined by law, such as cash payments.

Which version of PANTHEON do I need?

You need a current version with a maintenance agreement, because Datalab delivers regulatory changes through new versions. E-reporting requires version 50.10 or later.

Which information intermediaries does PANTHEON support?

PANTHEON works with several e-invoicing intermediaries, including Moj-eRačun (MER), FINA, PONDI and ZZI. The choice depends on your needs and your contract with the intermediary.

Can you set up Fiscalization 2.0 for us?

Yes. We check your PANTHEON version, set up registers, documents, fiscal counters and workflows for your chosen intermediary, and train your users.
