Payment of insurance premiums

The payment of social security premiums and contributions to the state employment policy is regulated by Act No 589/1992 Coll., on social security insurance premiums and contributions to the state employment policy, as amended. More about insurance premium rates.

A self-employed person pays:

• pension insurance premiums; or
• advances payments on insurance premiums and supplementary payments of these insurance premiums; and
• sickness insurance premiums, if he or she voluntarily participates in sickness insurance.

A self-employed person pays insurance premiums to the account of the competent social security administration. Information about individual accounts DSSA are here. A self-employed person will also receive the above and other information in an informative letter from the competent DSSA on the basis of a notification of commencement of self-employment on the prescribed form. The payment of the insurance premium must also be marked with a variable symbol.

Self-employed person’s variable symbol

For the payment of pension insurance premiums, the self-employed person shall indicate an 8-digit variable symbol, which the DSSA assigns to self-employed persons upon notification of the commencement of self-employment. This is a unique identifier of a self-employed persons in the records of the DSSA. Only with the indication of this variable symbol is it possible to post the payment to the relevant account of the payer of the insurance premium.

The variable symbol for the payment of sickness insurance premiums for self-employed persons is the birth number. If the self-employed person does not have a birth number, the variable symbol is the insurance registration number assigned by the DSSA.

The day of payment of the insurance premium is considered to be the day when the insurance premium is credited to the account of the competent DSSA.

Pension insurance premiums

Pension insurance premiums must be paid by any self-employed person who, in the previous year:

• pursued major activity as a self-employed person;
• pursued subsidiary activity as a self-employed person and became a member of the pension scheme;
• pursued subsidiary activity as a self-employed person and applied to become a member of the pension scheme.

The advance payment is 29.2% of the monthly assessment basis. The minimum amount of the advance payment is determined annually from the assessment basis, which is 55% of the average tax basis achieved in the previous calendar year (in accordance with the Income Tax Act). The minimum assessment basis is regulated annually by a regulation of the Government of the Czech Republic and it differs for major and subsidiary activity as a self-employed person (more in Czech).

The advance payment can be paid from the 1st to the last day of the calendar month for which the advance payment is paid. This means that the advance payment for January is due from 1 January to 31 January, etc. The advance payment is 29.2% of the monthly assessment basis. The advance payment for the calendar month in which the activity as a self-employed person was started may be paid until the end of the following month.

Supplementary payments of pension insurance premiums

The supplementary payment is the difference between the total pension insurance premium for a given year and the advances paid for the given calendar year. The supplement is calculated by the self-employed person in the Statement on Income and Expenses for the calendar year or it is determined by the locally competent DSSA in the calculation of the insurance premium for the given calendar year.

Pension insurance premiums and contributions to the state employment policy, as well as the supplementary payments for these premiums for a given calendar year, are payable no later than eight days after the day on which the Statement on Income and Expenses of a self-employed person was or should have been submitted. In the event of a failure to comply with the said deadline, a statutory late payment interest arises in the amount of 0.05% of the outstanding premium amount for each day of delay.

Self-employed persons applying a flat-rate scheme

Effective from 1 January 2021, Act No. 586/1992 Coll., on income tax, as amended, has been amended to allow the self-employed persons to apply the flat-rate scheme, subject to the conditions laid down in the amended Act, thus becoming payers applying a flat-rate scheme. From 1 January 2025, the income limit in a given calendar year is set at CZK 2.000.000.

CSSA is not authorised to provide any information concerning the entry and conditions for participation in the flat-rate scheme, therefore we recommend to follow the website of the tax administration - the Financial Administration authorities.

Notification of the  commencement or the  termination of self-employment upon entry into or exit from the flat-rate  scheme
Self-employed persons notify the Financial Administration authorities of the commencement of their activities and entry into the flat-rate scheme. Together with the notification of entry into the flat-rate scheme, a self-employed person can register for sickness insurance.The transfer of data by a tax administrator to the CSSA is considered to be compliance with the reporting obligation and submission of an application for sickness insurance. A self-employed person who is a taxpayer under the flat-rate scheme notifies the financial administration authorities of the termination of this flat-rate scheme. This notification may also be accompanied by a notification of termination of self-employment.

Flat-rate tax and flat-rate premiums shall be paid to the Financial Administration authorities in the form of monthly flat-rate advances, which will include: an advance on health insurance, an advance on pension insurance and an advance on personal income tax amount of each of the advances is subject to annual change.

The self-employed person shall not file the statement of income and expenses for the calendar year for which their personal income tax is equal to the flat-rate tax. If any of the flat-rate scheme conditions is violated, even during the period in which the self-employed person participates in the flat-rate mode, the obligation to file the statement will arise.

If self-employed person is subject to the social security legislation of another state (application of other legislation has been determined), the self-employed person shall be treated as a flat-rate taxpayer for the purposes of the payment of advances on premiums until the end of the calendar month in which they were subject to the Czech social security legislation most recently. However, such person shall be required to file the statement for such calendar year.

From 2023, a self-employed person who has met the conditions for participation in the flat-rate scheme will choose from three flat-rate bands when entering the flat-rate scheme, according to which the amount of the flat-rate advance payment is determined. However, the choice of a flat rate band depends on the income from self-employment that the self-employed person had in the previous calendar year and also on the activity from which this income derives.

Flat-rate bands for 2024 giving flat-rate advances
Band I  - CZK 7.498
Band II - CZK 16.745
Band III - CZK 27.139 

Flat-rate bands for 2025 giving flat-rate advances
Band I  - CZK 8.765
Band II - CZK 16.745
Band III - CZK 27.139 

A self-employed person who was already a taxpayer in the flat-rate scheme in 2024 and continues to be so in 2025 may notify the Financial Administration authorities of a change in the flat-rate band no later than 10 January 2025. If they fail to do so, the flat rate band from the previous year remains in force. A self-employed person may, or must (if their income for the previous tax period has exceeded the amount of income applicable to the selected flat-rate tax band) change the flat-rate tax band for each tax period (if they are already a taxpayer in the flat-rate scheme, and always by 10 January of the following calendar year).
A taxpayer under the flat-rate  scheme whose income tax for a given calendar year is equal to the flat-rate tax, does not submit a tax return or a summary of self-employed income and expenses (the "summary") to the relevant DSSA and the relevant  sickness insurance company. In the event of failure to comply with any of the conditions of the flat-rate regime, even during the period in which the self-employed person participates in the flat-rate scheme, there will be an obligation to submit the summary.

The following are considered to be breaches of the conditions:

• the self-employed person has failed to meet the conditions for joining the flat-rate;
• scheme,the self-employed person has taxable income from self-employment exceeding CZK 2,000,000;
• the self-employed person has become a VAT payer or has become subject to VAT registration;
• the self-employed person has become a partner in a publicly traded company or a limited partnership company.

A self-employed persons may apply for voluntary sickness insurance, either while giving their notification to tax authorities of their application of the flat-rate scheme or at any time during the period for which they apply the flat-rate scheme. If the self-employed person has already participated in sickness insurance before entering the flat-rate scheme, their participation remain unchanged. Sickness insurance payments are not part of the flat-rate advances paid monthly by the self-employed person applying the flat-rate scheme to the tax administration, but should be paid independently by the due date to the account of the relevant DSSA with the right identification (variable symbol). The maximum payment for self-employed sickness insurance in the flat-rate scheme varies depending on the selected flat-rate band.
