Czech Freelancer Tax & Income Calculator 2025

The Czech Freelance Tax Calculator helps you calculate your net income after all mandatory deductions, including income tax, health insurance, and social security. The tool automatically applies the standard taxpayer discount (CZK 30,840 in 2025), which reduces income tax if your taxable income is below that amount. Just enter your yearly gross income and personal details to see your complete tax breakdown.

Yes — if you're freelancing in the Czech Republic, you need to register a trade license (Živnostenský list) to operate legally and invoice clients. This license allows you to declare self-employed income, register your business activity, and receive a tax ID and business ID.

Once registered, you can issue proper Czech invoices. Need help? Use Pexpats’ free Online Invoice Generator to create invoices automatically.

There are two tax rates for Czech freelancers in 2025: the standard 15 percent, and the progressive 23 percent. Which tax rate you pay depends on your annual clean income. In 2025, the income limit for the 23% tax rate is average gross salary multiplied by 36. That is CZK 46 557 (average gross) x 36 = CZK 1 676 052. For earnings of this amount or lower, the 15% tax rate applies. Any clean income over this amount then has a 23 percent tax rate.

In the first year of freelancing, you pay only the minimum monthly social security and health insurance deposits. At the end of the year, you may then need to pay a balance depending on the amount of income earned. In 2025, social security will require 29.2% from fifty-five percent of annual clean income. Health insurance will be 13.5% from fifty-five percent of annual clean income.

Thus, if your earnings are higher than what the minimum deposits cover, it’s advisable to pay higher deposits voluntarily. This will help to offset any final balance remaining at the end of the year.

The 60/40 method provides an expense allowance for 60% of gross annual income to taxpayers. In this case, the taxpayer will not need to provide any invoices to prove real expenses. Instead, they simply deduct 60% from gross income, and the remaining 40% is taxable. Note that this method is only applicable to earnings under CZK 2 million per year.

It’s possible to deduct any business expenses from your income tax report, but only if filing ‘real expenses’. In this case, you cannot file using the 60/40 method. Thus, it’s always best to consider whether your real expenses are higher than 60% of your gross income. Usually, this will not be the case, especially for freelancers in consultancy, sales, and IT industries. These workers tend to have less business expenses and find the 60/40 method more affordable.

To find net income from crypto or from capital gains, use: sale price - purchase / investment price - transaction costs = tax base. For crypto, this might also include any transaction fees, which are deductible from the final sale price. The remainder is the taxable profit (tax base), which then carries 15% or 23% tax rates.

“Tax discounts” are any deductibles which reduce a taxpayer’s total income tax. Take for examples the standard taxpayers’ discount, life insurance payments, mortgage interest rates, and claiming a spouse with lower income. Each of these events reduces the total taxable net income on the tax return. A tax credit on the other hand is a refund amount from the financial office depending on your income.

One of the most common tax credits is claiming a child under 21 years old. Taxpayers may also use tax credits in replace of tax discounts when filing.

Freelancers in the Czech Republic can deduct up to CZK 150,000 per year from their taxable income for mortgage interest payments. This tax relief lowers your income tax because the mortgage interest is subtracted from your tax base before the tax is calculated.

You can only claim this deduction for the months when you were making mortgage payments in the previous year.

Taxpayers are also eligible to claim tax deductibles for any investments into private life insurance, or private pension and retirement funds. For life insurance, there is a maximum deductible of CZK 24,000. The same amount applies to claims for private pension and retirement savings (within the non-government sector).

Yes. You should have a Czech bank account for receiving payments for all invoices. It’s also more convenient for keeping track and calculating trade license taxes, insurance, and your social security contributions. You can also use Revolut or Wise for invoicing your clients.

There is no law stating that you must have a business bank account. However, having one can make tax reporting much easier. This is especially true if you do not want to use the 60/40 method, and instead will file taxes declaring real expenses. In this case, having a business bank account can save not only time but also reduce costs in accountancy fees. It also makes it easier to keep track of all business-related expenses in general, including contributions to social security and health insurance.

Yes - it is possible to invoice in EUR or in USD, but always add a note onto the invoice stating the exchange rate from CNB on the date of issue. For example, a note on the invoice would say: “on 1.1.2025, the exchange rate of EUR 1 = CZK 24,48.

If you are a student freelancer in the Czech Republic and earn less than CZK 111,736 per year, you don’t pay income tax or social security contributions. But you must still pay for health insurance.

For students earning more than that threshold, taxes are calculated like this:

• Income Tax = (40% of gross income using 60/40 expense method) × 0.15 − CZK 30,840 (standard taxpayer discount)

• Health Insurance = (40% of gross income) × 50% × 0.135

Meet Alex, a freelancer marketing consultant earning CZK 600 000 per year and using the 60/40 tax reporting method. In this case, Alex reports:

• 60% of CZK 600,000 = CZK 360 000 (expenses), and 

• 40% of CZK 600,000 = CZK 240,000 (tax base).

Additionally, Alex has a wife, Kate. She is on parental leave, and she and Alex are raising two children together. Meanwhile, Kate’s income does not surpass CZK 68 000, so Alex claims a wife with lower income on the tax return. On top of this, Alex is paying a mortgage interest rate of CZK 50,000 annually.

What discounts can Alex claim? Let’s look:

• Standard taxpayer’s discount = CZK 30,840 

• Spouse with income below 68 000 CZK annual = CZK 24,840 

• Tax discount for the first child = CZK 15,204 

• Tax discount for the second child = CZK 22,320 

But what about the payments in mortgage interest fees? These can also reduce the tax base! The final calculation then becomes:

• CZK 240,000 – 50,000 = CZK 190,000

Now, Alex is looking at:

• 15% tax rate on CZK 190,000 = CZK 28,500 income tax (before discounts)

• CZK 28,500 - 30,840 (the standard taxpayer’s discount) - CZK 24,840 (additional tax relief) = Zero income tax owed.

• Also, as Alex’s discounts total more than the income tax he should pay, he is entitled to a tax bonus of CZK 15,204 + 22,320 = CZK 37,524.

Not only has Alex reduced his income tax to zero in this case, he claims money back in his tax return.
