Salary Calculator Croatia 2026 — Gross to Net, Net to Gross (EUR)

How to change the PK Card (Tax Card) and activate a tax relief?

The golden rule of every salary calculation in Croatia is the following: the employer pays the salary exclusively relying on your current data in the tax card, which it pulls via an online connection and service (Tax Administration) from your file! If a child, a person with zero income, or an established civil disability is not processed and entered by the worker into the centralized tax register, that attribute will not exist at all! Accounting departments are not allowed to handle this themselves. You must provide them with a valid, updated new card!

Option A: Digital path via e-Citizens (Fastest & Recommended)

Absolute recommendation. Today, rarely anyone physically goes to knock on clerks' doors to record changes. The Tax Administration has integrated a very high-quality mechanism that saves you months of time in applications.

Steps from the comfort of your home

Log into the national portal e-Građani using the NIAS system.
Select the Tax Administration system option from the extremely massive long list of services.
Within the highly visible visual central menu of the portal's profile section, select the tab module "Moje porezne kartice / Zahtjev za promjenom" (My tax cards / Request for change).
The system will warn you that you are making a document change (you are not penalized for this). Then click the green option on the form Add Dependent Member, indicate the relationship (e.g., Child 1), enter their identification number, and upload proof attachments (A color PDF scan or high-quality JPG photograph of the birth certificate).
The clerk's office will process this quick request asynchronously within a day or a few days at most. The central system automatically updates the state parameters. An Updated PDF card form arrives as a message in your e-Inbox.
Very Important: You must strictly and urgently forward that refreshed new PDF document via e-mail to the Human Resources department, i.e., payroll at your company/work, and emphasize: "Please pay the salary for the next current date with my new tax card, attached. A child has been added!".

Option B: Physical submission

For foreigners without an issued bank certificate (lack of permission in the digital system), as well as highly traditional taxpayers from rural villages for whom a token is by no means an option - the procedure requires a return to old paper filing at the local branch office of the tax clerk exclusively according to the valid municipality of your current prescribed residence/stay.

Print out the Form, preferably sign it at the bottom with a pen, and bring it.
Attach all birth certificates, registry extracts, and marriage certificates of natural children to the counter at the reception desk for verification by the clerk at the counter.
The clerk immediately stamps the printout of the new extract. Hurry with it directly to the company that same week before the date of the classic accounting closure of operations.

Retroactive period (The year has passed, it's time for tax returns)

Were you late registering your son in March and only reported the card to work in August? The state legally took (in the collection of the existing tax regulation) several increased net installments from you! The answer is fantastic - it's not lost! The procedure for correcting the injustice will occur regularly towards the end of February of the following frozen year when you must submit a special request for the "Annual Declaration of Payment of Surplus". After the summer, the Tax Administration manually corrects the calculations for the entire year and refunds your saved tax difference!
