Social security contributions are a significant part of the cost of employing every worker in Poland. Every business that hires staff under an employment contract (umowa o pracę) needs to understand how contributions to ZUS (Social Insurance Institution) are calculated and paid. The system covers several types of insurance with different rates and different ways of financing. ZUS contributions on a contract of mandate are calculated differently, and we cover them separately.
The ZUS contribution system in Poland has a complex structure: part of the cost is borne by the employer and part is deducted directly from the employee's salary. Knowing these rules is key to planning employment costs properly and to meeting the obligations under the social insurance rules.
Compulsory ZUS insurance of employees
Every employee hired under an employment contract is compulsorily insured with ZUS. This obligation arises directly from the Social Insurance System Act (ustawa o systemie ubezpieczeń społecznych) and applies to all forms of employment, regardless of salary or working hours.
ZUS contributions are calculated on the employee's gross salary, which means the base is the full amount of pay before income tax and other contributions are deducted. This keeps contributions proportional to the employee's earnings. However, the annual base for pension and disability contributions is capped at 30 times the forecast average salary - in 2026 this is PLN 282,600 (Article 19(1) of the Social Insurance System Act). Special cases, such as ZUS contributions for a pensioner on a contract of mandate, need to be looked at separately.
The social insurance obligation starts on the day the employment relationship begins and lasts for the whole period of employment. The employer registers the employee for insurance (form ZUS ZUA, the insurance registration form) within 7 days of the obligation arising (Article 36(4) of the Social Insurance System Act)
Contributions currently cover four social insurances (pension, disability, accident and sickness) plus health insurance. In addition, employers pay contributions to the Labour Fund (Fundusz Pracy), the Solidarity Fund (Fundusz Solidarnościowy), the Guaranteed Employee Benefits Fund (FGŚP) and - only for some employees - the Bridging Pension Fund (Fundusz Emerytur Pomostowych). Each of these has its own rate and way of financing.
Each contribution has a different rate. Social insurance rates are set by Article 22 of the Social Insurance System Act, and fund contribution rates by, among others, the budget act for the given year. The different rates reflect the different purposes and types of benefits paid from each fund.
The contributions are also financed from different sources. Some are deducted from the employee's salary, which directly reduces their income, and some are paid by the employer from its own funds as an additional cost of employment
Current ZUS contribution rates in 2026
The rates of social insurance and health contributions, of the Labour Fund, Solidarity Fund and FGŚP contributions, and the way they are financed did not change in 2026 compared with 2025. This stability lets employers predict employment costs and makes budget planning easier.
The pension contribution totals 19.52% of gross salary and is split equally between employer and employee. The employer pays 9.76%, and the same amount is deducted from the employee's salary. The split aims to share the burden of building pension capital fairly.
The pension contribution is fundamental to the employee's future pension. The money is recorded on the insured person's individual account and is the basis for calculating the future pension
The disability contribution is split unevenly. The employer bears the larger share, paying 6.50% of gross salary, while only 1.50% is deducted from the employee's pay. The total disability contribution is therefore 8.00% of the contribution base.
The sickness contribution of 2.45% is borne entirely by the employee through a deduction from salary. The employer does not finance this contribution, but for the first 33 days of illness in a calendar year (14 days for an employee aged 50 or over) it pays the employee sick pay itself (Article 92 § 1 of the Labour Code (Kodeks pracy)); sickness benefit (zasiłek chorobowy) from ZUS is paid for any further period. We include sick pay and contributions deducted from salaries in the payroll of clients who use our payroll services.
The sickness contribution entitles the employee to sickness benefit when they are unable to work due to illness. The amount of the benefit depends on the period of incapacity and on the contribution base
The accident insurance contribution is financed entirely by the employer. A payer that reports no more than 9 insured persons for this insurance pays 1.67%, i.e. 50% of the highest rate set for activity groups (Article 28(1) of the Accident Insurance Act); for larger payers the rate depends on the type of activity and the level of occupational risk. The rate is set for a contribution year that runs from 1 April to 31 March of the following year (Article 2(8) and Article 27(1) of the Accident Insurance Act), in line with the regulation on differentiating the accident insurance contribution rate (consolidated text Dz.U. 2025 poz. 1874).
- The accident contribution is differentiated by activity group and occupational risk category
- Rates for activity groups range from 0.67% to 3.33%
- The rate set for a specific payer can range from 0.40% to 8.12% (Article 22(1)(4) of the Social Insurance System Act)
- The 1.67% rate for payers reporting up to 9 insured persons also applies in the contribution year starting on 1 April 2026
- Before each contribution year (from 1 April) a payer's rate may change
The accident contribution finances benefits related to accidents at work and occupational diseases. Its level depends on the occupational hazards in the activity group and, for payers reporting at least 10 insured persons, also on the accident indicators at that payer, which is meant to motivate employers to improve workplace safety
Health contribution and additional charges
The health contribution is a significant part of the employee's burden, amounting to 9% of the base, i.e. gross salary reduced by the social insurance contributions financed by the employee (Articles 79 and 81 of the Act on Healthcare Services Financed from Public Funds). It is deducted entirely from the employee's salary, which means the employer bears no direct cost for its employees' health insurance.
The health contribution differs from the social contributions in that it goes to the National Health Fund (NFZ). The payer pays it to ZUS together with the other contributions, and ZUS passes it on to the NFZ; it has a different purpose - it finances healthcare for insured persons.
The health contribution entitles the employee and their family members to free healthcare within the public healthcare system. This includes doctor's appointments, diagnostic tests, hospital treatment and specialist care
Employers also bear additional charges in the form of contributions to non-insurance funds. In 2026 the Labour Fund and Solidarity Fund contributions total 2.45% of gross salary (1.00% for the Labour Fund and 1.45% for the Solidarity Fund - Budget Act for 2026, Dz.U. 2026 poz. 62, Articles 25-26), and they are paid entirely by the employer. They are not paid, among others, for an employee whose contribution base, converted to a monthly amount, is lower than the minimum wage (PLN 4,806 in 2026), or for women over 55 and men over 60 (Articles 259 and 261 of the Act on the Labour Market and Employment Services).
The Guaranteed Employee Benefits Fund (FGŚP) contribution is 0.10% of gross salary (Article 27 of the Budget Act for 2026) and is also paid by the employer. This fund protects employees if the employer becomes insolvent, securing payment of outstanding salaries and severance pay.
The Guaranteed Employee Benefits Fund works as insurance against the employer's bankruptcy. Employees can receive outstanding salaries, severance pay and other employee entitlements from this fund up to specified limits
There is also a Bridging Pension Fund contribution of 1.5% (Article 36(1) of the Bridging Pensions Act), which applies only to employees performing work in special conditions or of a special nature. This contribution does not apply to all employees.
Split of costs between employer and employee
An analysis of how ZUS contribution costs are split shows that the burden is divided between employer and employee in different ways. The employer bears the larger share, paying contributions totalling about 20.48% of the employee's gross salary (with an accident contribution of 1.67%).
On the employer's side the charges include the pension contribution of 9.76%, the disability contribution of 6.50%, the accident contribution of 1.67%, the Labour Fund and Solidarity Fund contributions of 2.45% and the FGŚP contribution of 0.10%. In addition, a Bridging Pension Fund contribution of 1.5% may apply for certain occupational groups.
- Pension contribution financed by the employer: 9.76%
- Disability contribution financed by the employer: 6.50%
- Accident contribution paid entirely by the employer: 1.67%
- Labour Fund (1.00%) and Solidarity Fund (1.45%) contributions paid by the employer: 2.45%
- FGŚP contribution paid by the employer: 0.10%
The employee bears the pension contribution of 9.76%, the disability contribution of 1.50%, the sickness contribution of 2.45% and the health contribution of 9%. The employee's social contributions total 13.71% of gross salary, and the health contribution is calculated on salary reduced by those contributions, so the employee's total burden is about 21.48% of gross salary.
Contributions deducted from the employee's salary directly affect their net pay. Here the employer acts as the payer, which collects the contributions and passes them on to the relevant institutions
This split of costs reflects the different nature of each insurance. Pension and disability contributions are shared because they concern long-term benefits, from which both the employee and the employer benefit through the stability of the social system.
For example, with a gross salary of PLN 5,000 the employer pays additional contributions of PLN 1,024 a month (20.48%, with an accident contribution of 1.67% and without PPK), and PLN 1,073.81 is deducted from the employee's salary: PLN 685.50 in social contributions and PLN 388.31 in health contribution. The total cost of employment for the employer is therefore PLN 6,024 a month.
Calculating the total cost of employment
The total cost of employing a worker consists of the gross salary plus all contributions financed by the employer. This calculation is key to planning the staff budget properly and making hiring decisions.
The basic components of the cost of employment are the employee's gross salary, the employer's pension contribution, the employer's disability contribution, the accident contribution, the Labour Fund and Solidarity Fund contributions and the FGŚP contribution. In some cases there may also be a Bridging Pension Fund contribution.
Remember that the total cost of employing a worker consists of the gross salary and the contributions financed by the employer. These additional costs amount to about 20.48% of the employee's gross salary (with an accident contribution of 1.67%)
Calculating the total cost of employment requires taking into account all compulsory contributions and any additional employee benefits. Employers should also remember the cost of HR and payroll services, any additional insurance, and payments to PPK (Employee Capital Plans) if the employee participates (the employer's basic payment is 1.5% of salary - Article 26(1) of the Employee Capital Plans Act).
When planning employment costs, also take into account periodic changes in contributions, such as the annual update of the accident contribution. The accident contribution rate applies for a contribution year (from 1 April to 31 March of the following year), after which it may change.
Employers should regularly monitor changes in ZUS contribution rules, as they may affect the total cost of employment. Changes in the accident contribution are particularly important: rates for activity groups range from 0.67% to 3.33%, and for a specific payer from 0.40% to 8.12%
An accurate calculation of an employee's pay requires taking into account all deductions and contributions. The process involves calculating gross pay, calculating ZUS and health contributions, determining the tax base and calculating personal income tax.
Practical aspects of settling ZUS contributions
Settling ZUS contributions for employees requires a systematic approach and knowledge of the payment deadlines. Employers must transfer contributions to ZUS within set deadlines, and delays may lead to interest and penalties.
ZUS contributions are settled monthly. A payer with legal personality (e.g. a sp. z o.o. (limited liability company)) pays them by the 15th of the following month, while other payers, e.g. a business owner running a JDG (sole proprietorship), pay by the 20th; budgetary units pay by the 5th (Article 47(1) of the Social Insurance System Act). This means that a company must pay contributions for January by 15 February, and a business owner who is a natural person by 20 February, and so on. Keeping to these deadlines is key to avoiding extra costs.
The employer must keep contribution records for each employee, documenting the contribution base, the contributions calculated and the dates they were paid. These records may be checked during a ZUS inspection
Settling contributions also involves filing monthly settlement declarations, in which the employer reports the number of insured employees, the contribution bases and the contributions due. As a rule these documents are submitted electronically (from payroll software or via the ZUS online system); a payer settling contributions for no more than 5 persons may also file them on paper (Article 47a(1)-(2) of the Social Insurance System Act).
- Calculate contributions on each employee's gross salary
- Prepare the monthly settlement declaration
- Transfer the contributions to ZUS by the 15th or 20th of the following month (depending on the type of payer)
- Keep contribution records for each employee
- Archive documents related to settling contributions
Employers must also remember their duty to inform employees about the contributions paid for them. Information on the data in the monthly reports for the previous year, broken down by month, is given to the employee by 28 February of the following year (Article 41(8) of the Social Insurance System Act).
Errors in settling ZUS contributions may require filing a corrected declaration and paying the amounts due with interest. That is why precise records and regular checks of the calculations are so important
Impact of contributions on the employee's net pay
ZUS and health contributions directly affect the net pay the employee receives. Total contribution deductions amount to about 21.48% of gross salary, which is a significant part of the employee's income.
The pension contribution of 9.76%, deducted from gross salary, has the greatest impact on net pay. The next significant charge is the health contribution of 9%, which is deducted entirely from the employee's salary but calculated on the amount reduced by social contributions (about 7.77% of gross salary).
Employees should understand the structure of deductions from their pay so that they can plan their personal finances consciously. Knowing the contribution amounts helps when negotiating salary and planning a household budget
The disability contribution deducted from the employee's salary is 1.50%, and the sickness contribution 2.45%. Although smaller than the pension and health contributions, they also affect the final net pay.
When calculating net pay, also take into account personal income tax, which is calculated on revenue reduced by tax-deductible costs (PLN 250 or PLN 300 a month) and social insurance contributions. Since 2022 the health contribution cannot be deducted from tax.
An employee earning a gross salary of PLN 6,000 will have contributions of PLN 1,288.57 deducted (PLN 822.60 in social contributions and PLN 465.97 in health contribution). After deducting the tax advance (PLN 291 with costs of PLN 250 and a PIT-2 statement submitted, without PPK) their net pay will be PLN 4,420.43, which means that contributions and tax account for about 26% of gross salary.
Changes and outlook
The ZUS contribution system changes from time to time as a result of social insurance reforms and the state's budget needs. The rates of social insurance and health contributions and of contributions to non-insurance funds did not change in 2026 compared with 2025.
This stability benefits both employers and employees, as it makes employment costs predictable and supports financial planning. Nevertheless, employers should follow legislative changes that may affect future contribution charges.
The accident contribution deserves particular attention: for activity groups it ranges from 0.67% to 3.33% depending on the industry and level of occupational risk. The rate set for a payer applies for a contribution year - from 1 April to 31 March of the following year
Employers should also monitor changes in the rules on the contribution base and contribution caps. In 2026 the annual base for pension and disability contributions is capped at PLN 282,600; once it is exceeded these two contributions are no longer charged, while the sickness, accident and health contributions and the Labour Fund and Solidarity Fund contributions continue to be charged (Article 19(1) and Article 20(2) of the Social Insurance System Act, Article 259(1) of the Act on the Labour Market). These factors can significantly affect the total cost of employment, especially for highly paid employees.
Developments in IT may also affect how ZUS contributions are settled. Increasing digitalisation of HR and payroll processes can simplify settlement procedures and reduce the risk of calculation errors.
Employers should invest in modern HR and payroll systems that automate the calculation of ZUS contributions and minimise the risk of errors. Such solutions can also make reporting to ZUS and keeping the required records easier
