Ministers have denied tax-reform measures are being rushed through parliament despite just two days being set aside for an inquiry into the "once-in-a-generation" changes.
Changes limiting negative gearing to new houses from July 2027 and scrapping the 50 per cent capital gains tax discount to a rate based on inflation passed the House of Representatives on Thursday.
But the laws face an uncertain future, with the Greens yet to indicate if they will back the federal budget reforms through the Senate.
A two-day Senate inquiry will scrutinise the laws later in June before they go to the upper house, with the opposition and crossbenchers saying the measures are being rushed.
Assistant Treasurer Daniel Mulino said the laws were not being raced through as issues surrounding tax and housing had been on the agenda for a long period, alongside 17 hours of debate in parliament so far.
