II FSK 890/23) rozstrzygnął kwestię podatkowych skutków współfinansowania produkcji filmowej przez osobę fizyczną na podstawie umowy nienazwanej przypominającej spółkę cichą. Kluczowa wątpliwość dotyczyła tego czy wypłaty na rzecz inwestora (zwrot wkładu oraz późniejszy udział w zyskach z dystrybucji filmu) należy kwalifikować jako przychody z kapitałów pieniężnych (odsetki), czy jako przychody z innych źródeł (art. 20 ust. 1 ustawy o PIT).

The beginning of the year is the right time to plan activities related to fulfilling ownership structure reporting obligations applicable to real estate companies. For taxpayers whose tax year corresponds to the calendar year, the deadline for 2024 reporting is 31 March 2025. Nonetheless, it is advisable to begin preparations for meeting these obligations already at this stage.

We would like to remind you that, for taxpayers whose tax year coincides with the calendar year, the CIT settlement for 2024, due by 31 March 2025, will be the first requiring an analysis of whether the taxpayer is subject to the minimum CIT. Accordingly, it is advisable to begin, already at this stage, actions aimed at determining whether the company will be obliged to pay this tax.
