In a major economic speech in Sydney on Monday, Opposition Leader Sussan Ley will point to personal income tax cuts as the centrepiece of the policy offerings she will take to voters.
She will say future tax cuts will be focused on areas where financial burdens are being felt the hardest.
"We'll start where the pressure is greatest: low- and middle-income earners who are feeling the squeeze from higher prices and rising living costs," she will tell the Centre for Independent Studies.
"This is not a passing policy preference.Â
"It is more than just a commitment to lower taxes."
However, the scale of any potential tax cuts is yet to be determined, and firm details will only be announced closer to the next federal election.
The promise of tax cuts is one of the first policy priorities to be announced by Ms Ley since she took over as opposition leader after the coalition's worst-ever election loss to Labor in May.
Under then-leader Peter Dutton, the coalition opposed modest tax cuts flagged by Labor in its March budget.
The coalition's policies have been under review since its defeat, with areas such as energy and climate still to be determined amid internal party tensions.
Ms Ley will say any economic policy taken to the next election would have a firm focus.
"Every time we say no to Labor's waste, we will look first to return those savings to taxpayers or to strengthen the nation's finances," she will say.
"Every instinct in my being tells me that Australians should keep more of what they earn."
Ahead of Ms Ley's speech, Labor Treasurer Jim Chalmers attacked the coalition, saying it has "no costings, no details and no idea".
"When we legislated two more tax cuts for every taxpayer, the Liberals and Nationals voted against them and promised to repeal them," he said on Monday.
"If they won the election and had their way, income taxes would be going up, not down."
Dr Chalmers also accused the opposition of planning "savage cuts to Medicare" - a familiar Labor argument - under its ongoing promise to cut government spending and reduce the budget deficit.
"Labor is the only party delivering tax cuts for every taxpayer, including more tax cuts next year and the year after," he added.
The opposition leader will also use her speech to call for generational fairness for younger Australians and outline priorities in industrial relations.
She will say flexibility for workers remains important.
"Flexibility does not mean stripping away worker protections; it means giving workers more choice in how they balance work and life, and giving businesses the ability to test new ideas, attract talent, and reward merit," she will say.
"A fair and balanced industrial relations system would create more jobs and more productivity gains."
