Changes to capital gains taxes should still be broad to ensure one issue with the housing market isn't replaced by another, Treasurer Jim Chalmers says, despite business groups urging the reforms apply only to property.
The federal government will introduce its changes to the taxes to parliament on Thursday, in a bid to make it easier for more first home buyers to enter the market.
Under the changes, the 50 per cent discount on capital gains tax will be replaced from July 2027 with a rate based on inflation.
The government is still consulting with industry groups about potential carve-outs from the capital gains tax regime for startups, which could face their top marginal tax rate doubling to near 47 per cent when they sell their business.
