Taxes in the Czech Republic in 2026

The main deductions are personal income tax, social insurance and health insurance. Entrepreneurs must also monitor minimum monthly advances, the flat-rate tax scheme and the turnover limits for VAT registration.

Foreign residents should determine their Czech tax residence before filing, especially when they receive income from employment, business, rent or investments outside the Czech Republic.

Taxes on salary in 2026

The basic personal income tax rate is 15%. A 23% rate applies only to the part of the monthly tax base exceeding 146,901 CZK, not to the employee’s entire salary.

Employees also pay 7.1% of their assessment base in social insurance and 4.5% in health insurance. Employers pay additional contributions from their own funds. Current rates are published by the Czech Financial Administration and the Ministry of Labour and Social Affairs.

Tax credits for employees

The basic taxpayer credit is 30,840 CZK per year, or 2,570 CZK per month. To claim it monthly, the employee must sign the taxpayer declaration with one employer only.

The annual child tax credits are:

• 15,204 CZK for the first child;
• 22,320 CZK for the second child;
• 27,840 CZK for the third and every additional child.

The spouse tax credit is 24,840 CZK per year. It is available only when the spouses share a household with a dependent child under three and the other spouse’s annual income does not exceed 68,000 CZK. Detailed conditions are listed in the official 2026 tax guidance.

Who must file a tax return?

An employee with one employer, or several employers working consecutively, may usually request an annual tax settlement from the final employer.

A separate return is commonly required when a person works for several employers at the same time, runs a business or receives additional taxable income exceeding 20,000 CZK alongside employment. The general filing obligation also applies when annual taxable income exceeds 50,000 CZK or a tax loss is reported.

The deadlines in 2026 for income earned during 2025 were 1 April for paper filing, 4 May for electronic filing and 1 July when using a tax adviser or where an audit was required. Anyone who missed the applicable deadline should file as soon as possible through the MOJE daně portal. Income earned during 2026 will normally be declared in 2027.

Taxes and insurance for self-employed people

A self-employed person, officially called OSVČ, pays income tax on profit: business income minus recognised expenses. Depending on the activity, the taxpayer may use actual expenses or a statutory expense percentage.

The minimum health insurance advance for a main self-employed activity is 3,306 CZK per month in 2026. Some people with secondary activity or those insured by the state do not have to follow the minimum and may pay according to their actual profit.

The minimum social insurance advance for a main activity was 5,720 CZK at the beginning of 2026. From July, the minimum was reduced to 5,005 CZK for affected entrepreneurs. ČSSZ recalculates the amount according to the person’s previous income, so not every entrepreneur automatically pays the minimum. The change is explained by the Czech Social Security Administration.

Flat-rate tax in 2026

The flat-rate scheme combines income tax, social insurance and health insurance into one monthly payment. Entrepreneurs who meet all conditions usually do not submit a standard tax return or annual insurance reports.

• first band: 9,162 CZK per month;
• second band: 16,745 CZK;
• third band: 27,139 CZK.

The first-band payment was 9,984 CZK from January to June and fell to 9,162 CZK from July. This created an overpayment of 4,932 CZK for people who paid the full amount during the first half of the year. Current payments and conditions are published by the Financial Administration.

VAT registration and tax residence

VAT turnover is calculated for the calendar year. After exceeding 2,000,000 CZK, the business must monitor its registration obligation and normally becomes a VAT payer from the following year. If turnover exceeds 2,536,500 CZK, VAT status begins on the next day. The registration application must be filed within ten working days.

A person is generally a Czech tax resident if they have a permanent home in the country or normally stay there for at least 183 days during the calendar year. Czech residents usually declare worldwide income, while double taxation is addressed under the relevant international treaty.

Employees should check their tax credits and filing obligations, while entrepreneurs must monitor advances, VAT turnover and eligibility for the flat-rate scheme. Anyone with income from several countries should determine tax residence before preparing the return.
