Finance Minister Carlos Leitao will present his 2017-2018 budget on March 28 in Quebec City.
With his third consecutive balanced budget Leitao warned last month that his plan will show fiscal prudence.
The government announced investments into education and health last October, with a surplus of $2.2 billion in the 2015-2016 fiscal year.
The plan to abolish the health tax was also moved up to 2017.
With the government on good financial footing, Coalition Avenir Quebec leader Francois Legault is calling for a tax cut.
"To return $1,000 per family in the pockets of these families, I think we need that," said Legault.
He claims Quebecers come behind other provinces when it comes to disposable income.
"Last, 13 out of 13, for the average disposable income, so it means Quebecers, they are the people in Canada having less money in their pocket," said Legault.
Premier Philippe Couillard said Legault is cherry-picking his numbers based on tax brackets.
"It's close to $5000 that Quebecers have in their pockets that Ontarians do not have. So that's something that is also quite significant and I'd rather look at the bottom line number than a partial picture of reality like Mr. Legault wants to portray," said Couillard.
Parti Quebecois leader Jean-Francois Lisée said the Liberals are just pretending to reinvest in health care and education.
"When they Liberals say they're cutting, they cut. But when they say they're reinvesting, they don't," said Lisée.
Last year, the presentation of the government's budget was overshadowed by the simultaneous arrest of two former Liberal cabinet ministers, including Nathalie Normandeau.
The provincial budget comes nearly a week after the federal budget will be tabled, on March 22.
