Achievement of high quality of accounting information in financial statements requires thorough adherence to generally accepted accounting principles. In connection with deferred tax, this concerns especially the prudence principle and the going concern principle. The deferred tax also has an impact on fiscal sustainability in any given country. The aim of this contribution is to evaluate how information about deferred tax is reported by small and medium sized enterprises in Czech Republic and evaluate quality of such reporting. The research was conducted in the form of a questionnaire survey concerning recognition of deferred tax among accounting units which prepare their financial statements according to IFRS or according to Czech accounting standards. The entities that stated in the questionnaire that they recognize deferred tax were further analysed in more detail. The survey revealed that the standard does not take into consideration that small and medium-sized enterprises would not have to account for deferred tax. The research clearly showed the unwillingness of accounting entities to recognize deferred tax voluntarily.
