e-Pension is a service within the HITRO.HR service, by which the Croatian Institute for Pension Insurance offers its user an advanced electronic business method within their modernization and reorganization scheme.

The first e-Pension service is the e-registrations. This service supplements the previous standard method of registering pension insurance, with the option of submitting applications electronically.

When using the e-registrations service, you can do the following electronically:
- register commencement of operation and all changes in course of operation
- register your employees, all changes, and termination of their insurance

The e-registrations service enables employers and persons subject to pension insurance registration easier business operations, time savings and the option of registering faster, directly from the office or home, 24 hours a day, at a time convenient for them.
