This analysis is primarily conducted through the lens of established administrative court jurisprudence. The provisions of the Tax Ordinance provide for the institution of third-party liability for the tax obligations of corporate income taxpayers. Due to the subsidiary nature of third-party liability, tax authorities are obliged to demonstrate that the primary debtor – the corporate income tax taxpayer – is definitively unable to fulfill their tax payment obligation. This state must be regarded as a positive prerequisite for the mandatory determination of enforcement ineffectiveness. Since third-party tax liability is conditioned upon the ineffectiveness of tax debt enforcement, it is crucial to examine and understand the concepts of partial and complete enforcement ineffectiveness.}, title={Subsydiarny charakter odpowiedzialności podatkowej osób trzecich w podatku dochodowym od osób prawnych a bezskuteczność egzekucji wobec dłużnika pierwotnego}, type={text}, doi={https://doi.org/10.34616/151582}, keywords={administrative proceedings, administrative decision, third-party tax liability, ineffectiveness of enforcement}, }
