EOR onboarding in Croatia: five stages to the first payslip

Onboarding through an EOR in Croatia starts the moment your candidate says yes, and the first job is to collect the facts the contract will be built from. Getting them right now saves a corrected contract later, and a corrected contract is a new document the employee has to sign again.

We ask you, and then the new hire, for a short set of details:

• full legal name, address and personal identification number (OIB), which appears on the contract and on every payroll report
• nationality, and for anyone from outside the EU, the residence status that lets them work
• the agreed gross monthly salary in euro and any fixed allowances
• the job title, a short description of duties and the usual place of work, home included
• the first working day, weekly hours and whether the role is open-ended or for a fixed term
• whether the person already belongs to a second-pillar pension fund

The pension question sounds minor but changes the payroll from the first month. A member of the second pillar pays 15% into the first pillar and 5% into a personal fund held through REGOS, the Central Registry of Affiliates; someone in the first pillar alone pays the full 20% to the state. The total deducted is the same, yet the split must be right on the first report.

While the details come in, ask the candidate about their notice at their current job. When an employee resigns in Croatia, the same minimum periods apply as for a dismissal, unless a collective agreement or the contract gives the worker something shorter: 2 weeks in the first year, a month after one year, 2 months after five. A candidate with six years at their present employer may therefore owe two months. That figure, rather than any form, tends to decide the first day.

Croatian law wants the employment contract on paper, and wants the employee holding their copy before they do a single hour’s work. Where no written contract exists, the employer must at least confirm the agreed terms in writing ahead of the start; skip that too, and the job counts as open-ended by default.

Article 15 of the Labour Act lists what the document must state. Several of these items, such as leave, notice and pay periods, may point to the Act or a collective agreement instead of spelling out the detail, but they must be there:

• who the parties are, with each OIB, plus where the job is done and what it is called or involves
• the date of the contract and the date work begins
• whether it is open-ended, or else when the fixed term ends and why it is limited
• annual leave, the notice procedure and the notice periods
• gross salary broken into its parts, with the pay dates
• daily or weekly working hours, full-time or part-time
• training rights and the length and terms of any probation

Probation (probni rad) is optional and can last up to 6 months. If you want one, decide its length now: it cannot be added once the person has started, and it cannot be repeated if they later move to the same job under a new contract. If the person does not pass probation, the employer may end the contract on that ground with a minimum of seven days’ notice.

Fixing the term of a contract is only allowed for an objective reason, which has to be stated in the contract itself: cover for a colleague who is away, for example, or a project that ends of its own accord. Without that reason, or if the employee is still at their desk once the agreed term has run out, the law reads the contract as open-ended. Our article on Croatian employment contract rules covers these clauses in more detail.

The new employee must be registered for mandatory pension insurance no later than their first day at work. This is the step that cannot slip. Since the July 2026 amendments to Croatia’s undeclared work legislation took effect on the 7th, anyone working without a pension registration filed by their first morning is working undeclared, signed contract or not.

Registration is made with HZMO, the pension insurance institute, on form M-1P, and health insurance status with HZZO follows from it. Within 8 days of the registration deadline the employee is entitled to a copy of both registrations, which we send with their welcome pack.

The consequences of getting this wrong are set out precisely. A labour inspector from the State Inspectorate (Državni inspektorat) who uncovers undeclared work will assume half a year of full-time work preceded the visit, unless evidence points elsewhere. Registration must then follow within 3 days, and within 15 days the employer pays a set amount to the state: €2,650 the first time, €6,630 the second, and €8,000 per worker from the third finding within 3 years. That is before back pay at the national median wage, with contributions, for each undeclared month.

For an EOR client, the practical rule is simple. Do not let anyone start, even for an informal “meet the team” day, until we confirm the registration has gone through.

A non-EU hire adds one more gate. The Aliens Act (Zakon o strancima) allows such a worker to start only when two things are true: the employer holds the delivered permit confirmation, and pension and health registration is on file. Both conditions, not one, have to be met on the morning they arrive.

Once the person starts, the Labour Act’s working-time rules apply in full. Forty hours is the full-time maximum; extra hours have to be requested in writing and may not take the total beyond 50 in a week, and the annual overtime ceiling is 180 hours unless a collective agreement allows 250.

Every working day of 6 hours or more includes a break of at least 30 minutes, counted as working time. Between two working days the employee must have at least 12 hours of rest, and each week one full uninterrupted day on top of that daily rest, normally a Sunday. We keep the working-time records the Act requires, using the hours you or the employee report.

Annual leave builds from the start. In a first job, or after a break of more than 8 days between jobs, the full entitlement applies after 6 months of continuous work; before then it accrues at one-twelfth for each month. Someone joining in October will therefore have a few days for the rest of 2026 and their full allowance from the spring.

If the employee will work from home permanently, or on more than 7 working days a month, the contract must also cover how their costs are reimbursed. A tax-free lump sum of €4 per home-working day, up to €70 a month, can be paid through payroll.

Croatian salaries are paid in arrears for the month worked, by bank transfer, and the Labour Act fixes the outer payday at the fifteenth of the month that follows. Someone who starts on 1 November is therefore paid for November by 15 December at the latest.

On payroll day we calculate gross to net, withhold the employee’s pension contributions and income tax, and pay the employer’s 16.5% health contribution. Payment of the salary is also the moment the contributions become due. Those same figures feed the JOPPD, which goes to Porezna uprava electronically via ePorezna, and the payments made to the tax authority quote that report’s reference.

The income tax rate on that first payslip depends on where the employee lives. For a single Zagreb resident earning €3,500 a month, with the 23% lower rate and the €600 monthly personal allowance, take-home pay is about €2,294. Move the same person to Split and the figure rises to roughly €2,327; in Rijeka, to roughly €2,360. Our guide to Croatian payroll and the JOPPD report explains each line.

The employee must also receive a written pay statement (obračun plaće) no later than 15 days after payment. We send it electronically so that it is in their hands the day the money arrives.

Any allowances promised in the offer also run through this first payroll. Meal money paid in cash (capped at €1,200 yearly for tax purposes) or the home-working lump sum carries neither tax nor contributions within its limit, yet it is still reported, so it belongs in the offer letter in writing rather than as a vague promise. Above the limit the excess is taxed like salary.

For an EU citizen who already lives in Croatia, the steps fit into a short window, because none of them depends on an outside authority’s decision. A typical order looks like this:

• the candidate accepts, and you send us the details listed in stage one
• we draft the contract and you confirm the job description and any probation
• the employee signs, and gets their countersigned copy ahead of day one
• we register the employee with HZMO no later than day one
• the employee starts, and gets copies of the insurance registrations within 8 days
• payday for the first month arrives, no later than the fifteenth after month end, and the JOPPD goes in
• the pay statement reaches the employee within 15 days of payment

A non-EU hire is different. The stay and work permit comes first, and on the standard route MUP may take as long as 90 days, counted once the file is complete, to reach a decision. No contract start date should be fixed until the permit is in sight.

Whatever the nationality, keep one rule in mind for the timeline: every date after signature is counted from the first working day, so moving that day moves everything else. If a start slips by a week, tell us at once; the registration, the leave accrual and the first payroll all shift with it, and none of them can be backdated to suit the original plan.
