Poland has enacted a 60% windfall tax on excess revenues of oil and gas companies, with the proceeds intended to offset fuel price measures and support lower petrol station prices from November 2026.
Poland’s President Karol Nawrocki signed a windfall tax bill on 1 October 2026 that targets oil and gas companies.
Parliament had already approved the legislation, which aims to recapture profits that energy firms earned from supply disruptions caused by the Middle East conflict.
The tax applies to 2026 revenues that exceed the previous year’s average by 20% or more. Those excess revenues face a 60% tax rate.
Prime Minister Donald Tusk plans to use tax revenue from the bill to cut fuel prices at petrol stations. Finance Minister Andrzej Domanski said prices would drop by PLN 1.2 to 1.3 per litre by the weekend when the legislation takes effect.
Domanski stated he wants the price reduction programme to continue at least through the end of 2026.
The bill will be published today, 2 October 2026, following the president’s signature.
The windfall tax will apply from 1 November 2026, with monthly advance payments beginning in November 2026. The additional revenue will help offset VAT and excise tax losses from fuel price measures.
