The Polish government has approved a draft amendment to the tax act on the extraction of certain minerals, designed to ease the tax burden on copper producers, government spokesman Adam Szłapka announced on Tuesday. The cabinet also adopted draft changes to the acts regulating hard coal mining and personal income tax, paving the way for a gradual restructuring of Poland’s coal sector.
The Ministry of Finance, which prepared the proposal, said the reform aims to support copper producers as they invest in projects crucial for the energy transition, noting copper’s vital role in clean energy technologies. The tax reductions will be implemented in phases: in 2026, the coefficient used to calculate mineral extraction tax will drop from 0.85 to 0.74, followed by a further cut to 0.68 in 2027–2028.
Earlier drafts of the legislation, presented in July, proposed even lower coefficients — 0.71 for 2026 and 0.64 for 2027–2028 — but these were adjusted during consultations. According to ministry estimates, the reduced rates will lower annual state revenues from copper and silver mining taxes by about PLN 0.5 billion (EUR 117.2 million) in 2026, and by PLN 0.75 billion (EUR 175.8 million) per year in 2027–2028.
Separately, the draft amendment to the act on the functioning of hard coal mining and the personal income tax act will enable companies in the support system to gradually close down coal mines and pay social benefits to affected workers — a process previously blocked by legal constraints.
The new regulatory impact assessment projects that closing down Poland’s hard coal mines over the next decade will cost PLN 11.275 billion (EUR 2.6 billion). Earlier estimates placed the cost between PLN 4.182 billion (EUR 980 million) and PLN 9.125 billion (EUR 2.1 billion).
