The Czech tax calculator is an online tool that allows you to estimate how much you can get back in tax from the Czech Republic. Just answer a few simple questions in the calculator's intuitive interface. Once completed, you will see the expected refund you can get back after filing your tax return.

To calculate your tax overpayment, you will need the following information:

Income from employment: the total taxable income from your employer, including certificates of taxable income.

Business income: if you are in business, please include the income from your business and information on tax paid in advance.

Expenses: Choose whether you are applying actual expenses (indicate the total amount) or expenses as a percentage of income.

Tax allowances and benefits: Information on tax allowances such as personal tax allowance, spouse's allowance without own income, children's allowance and other tax allowances.

Entering this information accurately will ensure the most accurate estimate of your tax refund.
