OOTS go-live announcement - Croatia

Croatia currently offers e-Government procedures that help Croatians and EU citizens move freely between Croatia and the wider EU using the Once-Only Technical System (OOTS). This includes 19 out of the 21 procedures covered in the Single Digital Gateway (SDG) regulation.

Cross-border procedures are essential administrative steps when moving to, or doing business in another EU country, like notifying business permits, arranging tax affairs or applying to study.

The Croatian e-Citizens platform is an informative portal of electronic cross-border services of the Republic of Croatia. The e-Citizens Platform currently hosts 31 e-Services, the 21 SDG procedures and a catalogue of evidence types currently accepted when completing an SDG procedure. Croatia currently offers 19 out of the 21 SDG procedures for EU citizens moving to Croatia (as long as they have a valid electronic ID, or eID). Out of these, e-Government services helping people to study, submit their tax returns and set-up a business are among the most popular.

Thanks to a procedure’s integration with the Once-Only Technical System, users can:

  • authenticate themselves via their digital identity;
  • authorise the automatic retrieval of their data already registered with the authorities in their country of origin;
  • avoid manually uploading documents and certificates that are already available digitally in public administrations, wherever possible.

All this without duplicating information already provided, in the spirit of ‘Once Only’.

You can visit the Croatian e-Citizens platform to learn more about e-Government services in Croatia. You can visit the European Commission’s Once-Only hub to learn more about ‘Once-Only’ and see the 21 procedures included in the SDG regulation.
