The year 2026 will bring significant changes for self-employed workers, particularly in terms of tax and contribution costs. The increase in the minimum monthly wage from 20,800 CZK to 22,400 CZK will directly impact mandatory health and social security contributions. This parameter serves as the basis for calculating minimum payments, which will automatically rise. As a result, even businesses with lower profits will face higher expenses. Additionally, overall labor costs will increase, making it more expensive to offer jobs at the minimum wage.
Health and Social Contributions: New Amounts
In 2026, self-employed individuals will need to adjust to new minimum contribution levels. The minimum monthly health insurance payment will increase from 3,143 CZK to 3,306 CZK, starting from January. This amount represents the minimum threshold regardless of income, although the actual contribution depends on declared profits. The health insurance rate remains at 13.5% of the tax base.
Regarding social security, the minimum monthly payment will rise from 4,759 CZK to 5,720 CZK, calculated based on 40% of the average wage with a rate of 29.2%. However, a legislative proposal may keep the calculation at 35%, which would reduce the minimum to 5,005 CZK. In that case, any higher payments would be treated as overpayments.
Income Tax and Tax Benefits
The tax system for 2026 retains two income tax rates: 15% for the lower bracket and 23% for income exceeding 1,762,812 CZK, a higher threshold compared to the previous year. Taxpayers can reduce their tax liability through various tax credits and deductions.
Key benefits include a basic taxpayer credit of 30,840 CZK per year and a spouse allowance of up to 24,840 CZK, which doubles in cases of disability. There are also child tax credits, increasing from the first to the third child, along with additional benefits for disability. These tools can significantly reduce the overall tax burden.
Tax Bonuses, New Rules, and Deadlines
The increase in the minimum wage also affects eligibility for the child tax bonus. To qualify, annual income must reach at least six times the minimum wage, raising the threshold to 134,400 CZK in 2026. At the same time, the tax-exempt limit for pensions increases to 806,400 CZK annually.
New rules also clarify who is required to file a tax return. Newly included groups include certain foreign workers with high earnings and individuals who leave the flat-rate tax regime. Finally, the main deadlines are set for April 1, 2026, for paper submissions and May 4, 2026, for electronic filing, with an extension until July 1 for those using a tax advisor.
