The monograph addresses the issue of tax disclosure, which represents an essential component of enterprise management systems and their reporting frameworks. Tax reporting is examined in two dimensions: public reporting, which is made available to a broad range of stakeholders, and non-public (confidential) reporting, which is intended for tax administration authorities and submitted in the form of mandatory returns, reports, etc. The publication focuses on the management of the tax function and the reporting of taxation. The conceptual foundation for the analysis is the notion of full transparency in company operations, encompassing tax transparency and the principle of tax compliance. The publication further identifies the components of tax reporting, depending on the regulatory sources—tax law and accounting regulations. The study identifies corporate practices in disclosing tax information and advances the thesis that the current Polish legal and regulatory framework lacks a comprehensive solution for the disclosure of tax information to external users of financial statements. Enterprises disclose tax information primarily when such an obligation arises from tax law, which implies that the main recipients are tax authorities rather than the wider community of company stakeholders. The tax information currently presented in financial statements is confined to only a few aspects. The principal objective of the monograph was to develop a model for reporting tax information as an integral part of company financial statements.
