All insured persons pay contributions.

All those who are insured with OASI are obliged to pay contributions, with the exception of children and individuals who have reached the official retirement age and have no earned income.

Married persons without any earned income are also obliged to pay contributions. However, their contribution is deemed to have been paid if their employed spouse pays at least double the minimum OASI contribution on his or her income.

The contributions of employees are deducted from every salary payment by the employer and transferred to the compensation office together with the employer's contribution.

The non-working persons' contributions are calculated based on the replacement income and assets.
