17 March webinar: Tax Year-End Closing for 2025 – Key Issues

A practical webinar for CFOs, Chief Accountants and Tax Teams

Closing the 2025 tax year in CIT is not only about correctly recognising costs and revenues. It also involves technological and process challenges which, in recent months, have been increasingly affecting the day-to-day work of finance and tax departments—particularly in the context of JPK_CIT and the growing expectations of tax authorities regarding the quality of data and documentation.

During the session we will discuss the most important practical areas of the 2025 year-end closing from a CIT perspective. We will present proven approaches that help save time, streamline processes, and identify real opportunities for tax savings when finalising the CIT settlement for the last year.

Date: 17 March 2026
Time: 10:00–12:00
