Accace - Corporate income tax return in the Czech Republic

Filing a corporate income tax return is an important obligation for every company operating in the Czech Republic. This article summarises basic information on the deadlines, conditions and extension options for filing.

Basic deadlines for filing corporate income tax return in the Czech Republic

The deadline for filing a corporate income tax return in the Czech Republic depends on the tax year. The tax year may be either a calendar year or a fiscal year that starts on the first day of a calendar month other than January. The deadline for filing the tax return is identical for Czech tax residents and Czech tax non-residents.

  • General deadline: the tax return must be filed within three months after the end of the tax year. Therefore, if the tax year ends on 31 December 2024, the deadline for filing the return is 1 April 2025.
  • Electronic filing: If the taxpayer files the tax return electronically, the deadline for filing the tax return is extended by one month. Thus, in the example above, the deadline would be 2 May 2025.

Extension of time by tax adviser, statutory audit

Taxpayers can take advantage of the extension of time to file their return by granting a power of attorney to a certified tax advisor authorizing the filing of the return. In this case, the deadline is extended to six months after the end of the tax year.

  • Extended deadline: if the tax year ends on 31 December 2024, the deadline for filing the return is 1 July 2025.
  • This option also applies to companies subject to statutory audit.

Payment of tax liability

Income tax is due no later than the last day of the tax return filing period. This means that if the deadline is, for example, 1 April 2025, the tax must be paid no later than that date. In the case of an extended deadline, the due date for payment of the tax is also postponed.
