Poland will reduce copper ore mining tax from 2026

On May 23 (Friday), Polish Finance Minister Andrzej Domanski stated that under the new system, Poland's copper ore mining tax would be reduced starting next year.

The mineral extraction tax, which includes copper, was introduced in 2012. According to the annual report of KGHM, Poland's largest copper ore producer, the company paid 3.87 billion zlotys in taxes in 2024.

Domanski said that the tax reduction and the introduction of investment expenditure deductions would reduce tax revenue by approximately 10 billion zlotys ($2.66 billion) over a decade and lower costs for copper ore producers by the same amount.

Jakub Jaworowski, the Minister of State Assets, stated that, in fact, KGHM is the supplier of approximately 85% of Europe's copper, which is absolutely crucial.
