On 24 August 2018, the Ministry of Finance published a draft act amending the Personal Income Tax Act, the Corporate Income Tax Act, the Tax Ordinance Act and certain other acts (hereinafter referred to as the “Draft Amendment”). In the present article, we will focus on the most important planned changes in the Corporate Income Tax Act (hereinafter referred to as the CIT Act), as they can be approached from two perspectives. On the one hand, the Draft provides for considerably simplified procedures and introduces new tax incentives, and on the other hand, it introduces significant restrictions and difficulties for Polish entrepreneurs while boosting tax revenues in an effort to make the tax system more efficient.
