Employer payroll contributions: a complete overview

When an employer pays a wage, its real cost is always higher than the amount the worker receives in their account. The difference consists mainly of the employer’s payroll contributions, that is, the compulsory payments to the Social Insurance Agency (Sociálna poisťovňa) and the health insurance company that the company must pay on top of the gross wage. Understanding their structure is the basis both for planning personnel costs properly and for error-free payroll processing. When hiring employees, many entrepreneurs underestimate precisely this hidden part of the total labour cost and are later surprised by how much higher the real costs are compared with the agreed gross wage.

What employer payroll contributions consist of

Employer payroll contributions are made up of several items, each calculated as a percentage of the employee’s gross wage. They include health insurance and the individual social insurance funds – sickness, old-age and disability insurance, unemployment insurance, guarantee insurance, accident insurance and the reserve fund. Each fund has its own rate, and together they make up what is known as the total labour cost, that is, the employer’s overall cost. That is precisely why employer payroll contributions must not be confused with the contributions deducted from the employee’s gross wage.

• health insurance paid by the employer,
• the individual social insurance funds,
• accident and guarantee insurance,
• the contribution to the reserve fund.

How contributions are calculated

The calculation starts with the gross wage, from which the employee’s contributions and the advance tax payment are deducted first. The employer then adds its own share of contributions on top of the gross wage. For some funds, minimum and maximum assessment bases apply, which limit the amount from which contributions are calculated. The specific percentages and caps are adjusted and amended over time, so always check the current rates in the legislation in force or with your payroll accountant, so that the result matches reality.

Deadlines and obligations for contributions

Contributions are due on the wage payment date or within the period set by the insurers. The employer files monthly statements with the Social Insurance Agency and with the relevant health insurance companies and must pay the contributions on time; otherwise it faces penalties and late-payment interest. Registering and deregistering the employee correctly and on time is also important, because the obligation to pay contributions is tied to the duration of the insurance relationship. Even a registration that is one day late can mean a penalty.

Specifics of agreements and contribution relief

Employer payroll contributions differ according to the type of employment relationship. For agreements on work performed outside employment, the contribution burden may differ from that of a standard employment relationship, and in some cases there are deductible allowances for contribution purposes or other relief, for example for students or pension recipients. The assessment depends on the employee’s specific situation and the amount of their income, so it is worth evaluating each case individually rather than across the board.

Why it pays to leave payroll to the experts

Payroll administration is prone to errors – incorrect classification into a fund, a late statement or a wrongly set assessment base lead to arrears and penalties. Outsourced payroll processing ensures that employer payroll contributions are calculated correctly and paid on time, and you gain a clear overview of the real labour cost of each employee.

• precise calculation of both the net wage and the company’s costs,
• timely filing of statements and payments,
• handling of changes in legislation,
• less risk of penalties.

Frequently asked questions

Are employer payroll contributions a tax-deductible expense?

Yes, the contributions the employer pays for its employees are a tax-deductible expense of the company, provided the statutory conditions are met. They therefore reduce the tax base, but they must be properly recorded in the accounts and paid.

How do I find out an employee’s total labour cost?

All the employer’s contributions must be added to the gross wage. The sum makes up what is known as the total labour cost, that is, the real cost. The specific percentages change, so check the current rates or have your payroll accountant do the calculation.
