Mateusz Morawiecki told reporters that help would be available to a wider range of sectors hit by a lockdown.
He added that government support to help businesses survive the virus crisis so far totalled over PLN 200 billion.
Morawiecki announced the latest aid plan as Poland reported a new record daily rise in coronavirus infections, confirming 35,251 new cases on Thursday, the most since the pandemic hit the country more than a year ago.
Poland’s authorities in March last year unveiled a EUR 47 billion stimulus package to shield the country from the coronavirus outbreak.
Morawiecki in November pledged further billions in help for firms hit by COVID-19 curbs amid a second wave of the pandemic.
A stimulus package known as Financial Shield 2.0 was expanded in February to cover a further nine industries, among them education, retail and entertainment.
Help includes non-refundable subsidies, downtime pay, exemptions from social insurance contributions and additional social security benefits for employees, according to officials.
