Prime Minister Mateusz Morawiecki, who unveiled the package last week, told reporters on Tuesday that the Cabinet had begun to implement the policies, dubbed "the anti-inflationary shield."
He said that some of the measures still needed to be endorsed by parliament, while others would soon be introduced by a governmental decree.
"The anti-inflationary shield is designed to protect Polish families and Polish household budgets against price increases," Morawiecki added.
Compared to initial plans, the package has been extended to include a decrease in value-added tax on heating from networks from 23 percent to 8 percent, Morawiecki told the media.
The programme also comprises temporary reductions in excise tax on fuels and VAT on gas and electricity, as well as a one-time cost-of-living allowance for 7 million poorer households and a freeze on new government jobs, the PAP news agency reported.
The move comes as a flash estimate from the Polish statistics office showed on Tuesday that year-on-year inflation totalled 7.7 percent in November, above analysts' estimates and at a level not seen since 2000, news outlets reported.
