• Income tax for the self-employed and companies + contribution statements for the self-employed

This year, a new feature is entering our accounting jungle to encourage digitalisation. If you have a data box or an electronic signature, the tax office is now giving you an extra month. 🙂

3.5.2021 – Income tax return for self-employed people in paper form

1.6.2021 – Income tax return for self-employed people and companies in electronic form 

1.7.2021 – Income tax return for self-employed people and companies in any form (paper or electronic) through a tax adviser 

Those of you who have been self-employed for a while know that contribution statements can always be filed a month later than the tax return. So, how will it work now?

1.6.2021 – Statement to the health insurance company

1.7.2021 – Statement to the Social Security Administration

2.8.2021 – Statements to the health insurance company and Social Security Administration through a tax adviser

  • Road tax

This is the first tax deadline postponed this year because of COVID. Returns can be filed until 1.4.2021 instead of 1.2.2021 without any penalties. There is no need to notify anyone that you are using the extension.

  • Withholding tax and advance tax (employees, profit distributions)

1.3.2021 – Advance tax reconciliation in paper form

22.3.2021 – Advance tax reconciliation in electronic form

1.4.2021 – Withholding tax reconciliation


I certainly appreciate the extensions: processing most clients’ affairs in two months can be quite nerve-racking. So these changes bring you not only more time, but also a more pleasant accountant. 😇

An appeal to those who want the deadline extended through a tax adviser: the power of attorney must be filed with the tax office by the standard deadline, as if you were filing the return without an adviser. The price of the extension varies with complexity, at approximately 3 to 5 thousand Kč including VAT.

For my clients, I am working towards the standard deadlines without an extension. Do not worry: I am gradually getting stuck into everything and processing it. If you need your return prepared earlier for any reason (a mortgage, etc.), let me know in good time! 🙂

If you are unsure, feel free to get in touch and we will look at it together. 🙂
