Payroll and Tax Registration for Foreign Employees in Serbia: What Employers Must Set Up Before Day One

A foreign employee's work permit getting approved in Serbia is not the same as that employee being ready to receive a paycheck. Before the first salary payment can legally go out, an employer has to complete a separate set of tax and social insurance registration steps, calculate contributions against 2026's updated thresholds, and meet filing deadlines that run on their own schedule, independent of the immigration timeline. Employers who treat payroll setup as an afterthought once the work permit clears routinely find themselves unable to pay a new hire on time, which creates its own compliance exposure. Here is what has to be in place, and what changed for 2026.

Registration Comes Before the First Payslip

Two separate registrations have to happen before a foreign employee's first working day, and they go to different bodies.

• The employer itself must be registered with the Tax Administration and hold a tax identification number (PIB) if it does not already have one from prior operations in Serbia.
• Each individual worker, Serbian or foreign, must be enrolled with the Central Register of Mandatory Social Insurance before they start work. This registration is what activates pension, health and unemployment insurance coverage, and it is a precondition for legal employment, not a formality that can follow afterward.

Employment contracts for any employee, foreign workers included, must be in writing and in Serbian, though a dual-language version is permitted. The contract must state the identities of both parties, the place of work, the job description, the gross salary, working hours and payment deadlines. An employer without its own registered entity in Serbia generally needs a local payer structure to handle withholding, social insurance enrolment and filings. This is where many foreign employers hiring their first worker in Serbia either set up a local entity earlier than planned or use an Employer of Record arrangement to stay compliant from day one without doing so.

2026 Personal Income Tax: What Changed

Serbia's flat salary tax rate stays at 10 percent for 2026, applied to gross pay after deducting the employee's social contributions and a monthly non-taxable allowance. That non-taxable allowance increased for 2026: under amendments to the Law on Personal Income Tax published in late 2025, the monthly non-taxable amount rose to 34,221 RSD, up from 28,423 RSD, effective 1 January 2026. The next adjustment, tied to the annual consumer price index, is scheduled for early 2027.

For higher earners, Serbia also applies an annual personal income tax return (the PP GPDG) when a person's net income after tax and contributions exceeds three average annual salaries for the relevant year. This filing is separate from the monthly payroll process and falls on the individual, though employers supporting relocating employees typically coordinate the calculation so nothing is missed at year-end.

Social Insurance Contributions and the 2026 Bases

Social insurance contributions are calculated on gross salary and split between employee and employer across three funds.

• Pension and disability insurance (PIO): 14 percent withheld from the employee, 10 percent paid by the employer, 24 percent combined.
• Health insurance: 5.15 percent from the employee and 5.15 percent from the employer, 10.3 percent combined.
• Unemployment insurance: 0.75 percent from the employee only, with no employer-side contribution on this fund.

These percentages apply within a contribution base floor and ceiling that both moved for 2026. The lowest monthly contribution base rose to 51,297 RSD, up from 45,951 RSD, and the highest rose to 732,820 RSD, up from 656,425 RSD. The ceiling is set at five times the average monthly wage, which the relevant official gazette publication put at 146,564 RSD for the calculation. Employers running payroll for foreign hires at the higher end of the pay scale need to apply the updated ceiling, not the 2025 figure, from the first January 2026 payroll run.

Contributions and tax must be calculated and paid before net earnings reach the employee, not after. Filings are submitted electronically through the Tax Administration's portal, and the standard pattern is for the previous month's salary, tax and contributions to be settled by the end of the current month, unless an employment contract or collective agreement sets an earlier date.

The Minimum Wage Floor Employers Need to Plan Around

Serbia's minimum wage for 2026 is set at 371.00 RSD net per working hour, up from 337.00 RSD in 2025, under a rate published in the official gazette and effective 1 January 2026 for the full year. This figure matters directly for payroll setup involving foreign workers in lower-wage roles, such as seasonal agricultural or construction positions, where contracted pay needs to be checked against the new floor before an offer is finalised, not after the employee has already started.

Where Temporary Hiring Incentives Still Apply

Serbia maintains tax and contribution incentives for employers hiring certain categories of new employees, including refunds covering a share of the tax and contributions paid on a new hire's salary. Under the current rules, these incentives can still be used for hires made through 31 December 2026. To qualify, a "newly employed" person generally needs to have been registered with the National Employment Service without interruption for at least 6 months before hiring, or 3 months for trainees. These incentives are tied to registration history with the National Employment Service and are worth checking against a specific candidate's profile before assuming they apply, since not every foreign hire will meet the registration-history condition.

Why the Immigration and Payroll Timelines Need to Run Together

A work permit approval does not pause the payroll clock. Once a foreign employee's permit is granted and their start date is set, the employer has a narrow window to complete tax registration, Central Register enrolment and the first payroll calculation under the correct 2026 thresholds, all before the first salary becomes due. Employers who only start this process after the immigration file closes frequently end up either delaying the employee's start date or making a first payment that has to be corrected retroactively, which creates its own filing and compliance headache with the Tax Administration.

Nestlers Group's Payroll and HR Compliance team manages the full registration sequence for foreign hires in Serbia, from tax identification and Central Register enrolment through monthly payroll calculation against the current contribution bases and non-taxable thresholds. Our Employer of Record service in Serbia gives companies without a registered local entity a compliant route to employ staff immediately, with Nestlers acting as the legal employer for contracts, payroll and statutory filings. Our Tax Services team coordinates the annual PP GPDG filing for relocating employees who cross the income threshold, so the individual-level obligation does not fall through the gap between the immigration process and routine monthly payroll.
