In Poland, taxpayers can benefit from various deductions to reduce their income tax for the year 2025, with specific focus on the lesser-known deduction for union membership fees. This deduction, introduced in 2023, allows workers who are members of trade unions to offset their income by the amount of their paid membership fees, providing a potential savings of up to 840 PLN. The eligibility for this deduction is contingent upon actual membership and payment of fees during the taxable year.

The relief is applicable to individuals who file their taxes based on the tax scale and also to those on a lump-sum taxation scheme. This means that both employees with employment contracts and those involved in civil law contracts, as well as entrepreneurs, can take advantage of this deduction. However, it excludes individuals who file under a flat tax rate, unless they also have other income taxed under the scale system.

This tax relief is particularly significant as it encourages union membership and assists workers in offsetting some financial burdens—particularly in times of economic strain. Despite its introduction a few years ago, many taxpayers remain unaware of this benefit, highlighting a need for greater outreach and information dissemination from tax authorities to ensure eligible individuals make informed financial decisions regarding their taxes.
