Přechod na funkční měnu v rozsahu českých účetních předpisů

The diploma thesis deals with the issue of transition to a functional currency in the context of Czech accounting regulations, following legislative changes effective from 2024. The aim of the thesis is to analyze the legal, accounting, and tax aspects of maintaining accounting records in a functional currency and to assess the impact of this change on the faithful representation of financial reporting. The thesis compares the Czech framework with the rules of International Accounting Standard IAS 21 and evaluates the benefits and risks of a voluntary transition to a functional currency. The theoretical part defines key terms, conditions, and procedures related to the change of accounting currency. The practical part is based on a case study of a model company, in which a currency analysis is carried out, the functional currency is determined, and a subsequent restatement of financial statements is performed. The results show that keeping accounts in a functional currency enables a more faithful representation of economic reality, helps eliminate foreign exchange differences, and enhances the informative value of financial statements. The thesis concludes with recommendations for entities considering the adoption of a functional currency.
