Labor will seek details of the federal government’s tax reform plans when Senate estimates hearings resume on Monday.
The hearings are expected to dominate the parliamentary week, with the lower house debating budget savings bills.
Prime Minister Malcolm Turnbull on Friday said work on the budget, to be delivered in May, had superceded the tax white paper process set in train by Tony Abbott and Joe Hockey.
But an estimates question on notice tabled this week said the tax white paper work by a Treasury task force had not been suspended and 870 submissions had been received.
“Work on tax reform never stopped,” the Department of Prime Minister and Cabinet said.
“The fundamental objective is to support growth and jobs and the Treasury is working through all options for tax reform methodically.”
