Above lump-sum reserves of annual income and lump-sum expenditure for the year 2025
Please be aware that the flat tax in the Czech Republic has undergone several changes in 2025. These include: the division of tax rates into tax rate bands according to annual income and deductible expenses, an increase in the total income limit, and a change in the payment amount for each tax bracket.
Tax Rates vs Tax Bands vs Tax Brackets
- A tax rate band is the amount of income which will be taxed at a particular percentage (tax rate). The current tax rates are 40%, 60%, and 80%
- Example: the 60-40 tax reporting method is the most common. Using this method, the taxpayer deducts 60% of annual income, and pays tax on the remaining 40%
- Each tax bracket is a range of income with a different tax rate.
- In the Czech Republic, flat tax brackets are divided into earners up to 1 000 000 CZK, up to 1 500 000 CZK, or up to 2 000 000.
- The flat tax rate bands are further divided by the taxpayer’s reported deductible expenses: either at 40%, 60%, or 80%.
Tax Rates: 40%, 60%, and 80%
The amount of flat-rate expenses depends on the type of trade business. In other words, we calculate expenses as a percentage of revenue, depending on the area of business. We subtract:
- 80% of income from agricultural production, forestry and water management and income from craft trades; however, you can claim expenses up to the amount of 1 600 000 CZK
- 60% of income from trade business; however, you can claim up to 1 200 000 CZK
- 40% of other income from independent activities (with the exception of income according to paragraph 1 letter. (d) and paragraph 6), however, you can claim up to CZK 800 000
- 30% of rental income from commercial property; however, expenses up to CZK 600 000 can be claimed at most.

Switching Between Regular and Flat Tax
You have the option to choose between regular tax and flat tax once a year. This means you can switch from the regular tax method to the flat tax method, or vice versa. However, there are specific rules for when you can make this change:
- Changes can only be made once a year.
- You can make these changes from January 1st to January 11th.
- You must wait until the end of the tax year to make any changes.
When Is the Czech Flat Tax (Paušální Daň) Canceled?
The Czech flat tax (paušální daň) can be canceled for several reasons. Here are the main ones:
- You start qualifying for Czech national VAT. This doesn’t apply if you only qualify for "Light VAT."
- You became a shareholder of teh VOS (veřejná obchodní společnost) corporate.
- You officially declared bankruptcy, and the bankruptcy process wasn’t completed by the end of the tax year.
- Your trade license or other authority registrations were canceled.
- You got a full-time job with a Czech company and your trade license became a secondary income.
- You stopped working as a self-employed person in the Czech Republic and became a tax resident abroad.
Advantages and disadvantages of flat tax reporting
Keep in mind that the flat tax reporting method isn’t always advantageous to the taxpayer. In fact, the flat tax regime usually makes more sense for single entrepreneurs. This is because they often have fewer discounts and bonuses to claim. Take for example those for an unemployed spouse, or for having children.
Sure, there is less paperwork involved with the flat tax, and certainly less legwork and headache. But, if taking on the flat tax regime, there is no access to additional relief, discounts, and bonuses. Signing up for the flat tax can also complicate mortgage applications, and, in some cases, make it impossible to get Czech visa extended.
