Filing or Extending Income Tax Return

The Czech Bookkeeping year for SROs, trade licenses and private individuals (employees) runs from the 1st of January till the 31st of December, after which there is a 3-month period to file the last year's Income Tax Return.

Regular Filing of an Income Tax Return

Filing an Income Tax Return for 2018 is possible between 1.1.2019 and 31.03.2019.

After 31.03.2019 there is still a grace period of 5 days for regular filing; the Tax Office will not penalize filing and/or paying taxes during that period. However, after the grace period there will be a penalty with an interest component that grows by the day.

Filing for an Extension - not possible after 31st of March

Filing an Extension for 2018 is possible between 1.1.2019 and 31.03.2019. After 31.03.2019 requests for extension will not be accepted by the Tax Office anymore. There is NO 5-day grace period as with regular filing.

Extending your Tax Return means that we will get 3 months more to file (until 31.06.2019)

Our tax advisor will take over responsibility (from the tax subject) for the correctness of the Tax Return, 2 hours of his time for checking the the tax return are included in the extension fee.

An extension of a Tax Return can be ordered at the same time as the Tax Return itself is ordered - please go to the relevant pages here: - Czech Income Tax Return Service

Absolute Deadlines for Extending the 2019 Income Tax Return

31.03.2019 is a Sunday, which means that The Application for Extension, either sent as paper or electronically, must be in the Tax Office latest by Monday 01.04.2019.
Any Application for Extension that arrives after 01.04.2019 will not be granted by the Tax Office (!)

Since we need time to process the Power of Attorney, The PoA must be returned by Friday 29.3.2018 12:00 to our office, else we canot guarantee we can have it delivered in time at the Tax Office.

Penalties of Authorities

In case you do not file or extend a Tax Return in time, the tax office, social office and public health care will impose penalties, which can range between 500 CZK to several 10.000s of CZK.
These penalties have an interest component, so they grow by the day!

No money to pay the Income Taxes / Social Charges / Health Insurance now? Extend!

In case you do not have the money to pay the income taxes / social charges / health insurance now, then one option is to apply for an Extension, so you will have 3 more months more to generate money.

Another benefit of extending is that penalties and interest do not start running after 31.3.2019.
These can quickly cost more money than the fee for extension.
