Czech 2026 Progressive Tax Thresholds:

Change in the average wage and new thresholds for progressive taxation

For 2026, an average wage of CZK 48,967 is used for tax and insurance purposes in the Czech Republic. This amount has a direct impact on the threshold from which the second, increased tax rate applies. Under the consolidation package applicable also for 2026, the threshold for the 23% personal income tax rate is set at 36 times the average wage.

In 2026, this threshold corresponds to CZK 1,762,812 per year. On a monthly basis, this means that for employees with a monthly gross salary exceeding CZK 146,901, the portion of income above this threshold will be taxed at 23%, while the portion up to this limit is subject to the basic 15% rate.

The higher 23% rate applies only to the difference between the actual salary and the limit, while the remaining portion up to the limit is taxed at 15%. The monthly calculation of advance tax for employees is performed as follows: 15% applies to the portion of income up to 3 times the average wage, and 23% to the portion exceeding this threshold.

Related questions on progressive taxation thresholds

1. What is the exact monthly limit for applying the 23% rate in 2026?
The monthly limit is CZK 146,901 (3 times the average wage). From this amount, the higher rate applies to the portion of income that exceeds the limit.

2. Does exceeding the limit mean the rate increases for the entire salary?
No. The higher rate is applied progressively, i.e., only to the portion of income that exceeds the limit. The basic portion of income continues to be taxed at the 15% rate.

3. Does this limit apply to all employees?
Yes, the limit is set by the Czech Income Taxes Act across the board for all individuals, regardless of job title.

Maximum assessment base and the impact on social security contributions

While income tax is progressive, social security contributions are subject to a so-called cap. In 2026, the maximum assessment base is 48 times the average wage, i.e., CZK 2,350,416 per year. No social security contributions are paid on the amount exceeding this annual limit.

This creates the effect of a so-called degression of the overall tax burden for extremely high incomes. A manager with an annual income of CZK 3 million will pay income tax on the entire amount, but will pay social security contributions only on the first CZK 2.35 million.

There is no cap for health insurance contributions, and they are paid on the entire income without limitation. In practice, this means that for top managers, the employer’s payroll cost above the CZK 2.35 million per year threshold is proportionally lower, because the employer’s 24.8% social security contribution on the amount above the cap no longer applies.

Related questions on the assessment base

1. What happens if I exceed the maximum assessment base?
Once, in a calendar year, the total of your assessment bases reaches CZK 2,350,416, both you and your employer stop paying social security contributions on further income in that year.

2. Does the maximum assessment base apply the same way to employees and employers?
Yes, the cap applies to contributions on both sides.

3. Will this affect my future pension?
Yes, only income up to the maximum assessment base is taken into account for pension calculation. Amounts above this cap are not reflected in the pension assessment base.

Employee stock options and shares (ESOP)

In the area of employee share and option plans (ESOP), rules apply in 2026 that mitigate earlier disadvantages. This is a regime that addresses the issue of so-called “taxation without cash”. The current regulation in the Czech Income Taxes Act allows taxation of income from employee options and shares to be deferred until the moment the gain is actually realized.

The income is still considered employment income and is also subject to social security and health insurance contributions; however, the obligation to pay tax and insurance is deferred in time until the moment when the employee typically has funds available. Attorneys at ARROWS advokátní kanceláře help companies set up ESOP plans so that they meet the conditions for this more advantageous deferred-payment regime.

Sale of companies and ownership interests

For managers and investors, taxation of capital income is a key area. In 2026, individuals in the Czech Republic can still benefit from an exemption for income from the sale of securities and ownership interests, provided the so-called time test is met.

For securities (shares, bonds, mutual fund units), the exemption applies if the period between acquisition and sale exceeds 3 years. For ownership interests in a limited liability company (s.r.o.), the holding period must exceed 5 years for the income to be exempt from tax.

If the exempt income exceeds CZK 5,000,000, you are required to file a Notice of Exempt Income with the tax administrator. If you do not meet the time test, the income is taxed at 15% or 23%, depending on the overall tax base.

However, it is necessary to monitor whether the ownership interest was included in the business assets of a self-employed individual, because in such a case the exemption does not apply.

Table of risks and key issues

How your tax calculation will change in practice

Let’s illustrate the impacts with three model examples for 2026. Case 1 concerns middle management with an annual salary of CZK 1,800,000. The higher 23% tax applies only to the fraction of income above the threshold, while social security contributions are paid on the entire amount because it did not exceed the cap.

Case 2 presents a senior manager with an annual salary of CZK 2,500,000. Here, both thresholds already apply. Income tax is calculated progressively, but social security contributions are paid only on the amount of CZK 2,350,416. If an investor met the 5-year time test upon the sale of a company, the income is fully exempt from income tax.

Employee benefits in 2026

In 2026, the trend of tightening the rules for tax-exempt non-cash benefits continues. An important rule is the ban on so-called “salary swap”, i.e., providing benefits in exchange for a reduction in contractual salary. For the exemption of leisure-time benefits, a total annual limit applies in the amount of one half of the average wage.

This single limit aggregates contributions for holidays, pharmacy purchases, theatre tickets, or sports. If an employer provides benefits above this framework, the excess amount is considered taxable income of the employee. Our attorneys in Prague at ARROWS can help set internal policies to avoid additional assessments during an audit.

New obligations for employers

A major administrative change affecting payroll departments is preparation for the introduction of the Single Monthly Employer Report (JMHZ). The aim is to unify reporting for the Czech Social Security Administration and health insurance companies.

The system will require more detailed data on employees and their income in a single submission. For managers and statutory bodies, this means increased pressure on data accuracy in HR systems. We recommend monitoring the current legislative status.

Conclusion

The year 2026 brings new nominal thresholds for taxes and contributions for managers and high-income groups. Knowing the exact limits and the rules for exemption of investment income is essential for effective personal finance management. The key is not to underestimate administrative obligations, such as reporting exempt income.
