Anthony Albanese has been slammed by taxpayers for delivering a 'rambling' answer to a question about the government's changes to capital gains tax (CGT).

The government last week announced it would scrap the longstanding 50 per cent discount from July 1, 2027. It will be replaced with an inflation-adjusted system for assets held for more than 12 months.

The government has been arguing that the CGT change is about levelling the playing field in the housing market. 

But many investors have questioned why the CGT discount is also being scrapped not just for residential property, but for other assets, such as shares, as well. 

The Prime Minister was gently questioned about the issue by financial influencer Natasha 'Tash Invests' Etschmann, who said she was given three minutes to quiz the PM about the Budget in Canberra.  

'Why were the capital gains tax changes applied to all assets, rather than just residential property?' she asked. 

'Some people feel like it's unfair that it was applied to shares and businesses as well.'

Albanese responded by saying his government wanted to make sure that investment was driven towards more productive sides of the economy. 'Let me be clear,' he said. 

'The way that the system had worked had distorted the market. It had directed the investment much more towards property which is one of the things that contributed to the substantial distortion of the market towards housing rather than investment in equities or some other form,' Albanese said.

Etschmann then asked: 'Yeah, but it still feels like by changing CGT across all of assets still kind of incentivises people to invest in property.'

Albanese responded by giving her a history lesson. 

'There wasn't a tax on capital before 1985. It was then changed by John Howard to have this 50 per cent discount which shouldn't be the purpose.

'The purpose should be that greater equity between investing or receiving income from assets the way that it's treated and assets from work, so it's getting that rebalance there so that having capital gains tax based upon inflation means you're actually taxed based upon the real gain.

'If you get a real gain in your income, you get taxed on it.'

Taxpayers weren't buying Albanese's explanation, with one telling Ms Etschmann 'well done for trying'.

Another viewer added: 'I thought it was a meme using AI, sounded like he had a stroke.' 

A third said: 'Still waiting for the answer to your question.' 

'This is a politician's answer in its purest form,' said scientist Dr Matt Agnew. 

'"Let's be clear"... *proceeds to be unclear*', another viewer said.  

'Wants to "drive investment towards more productive sides of the economy", yet punishes business and shareholders the same as property,' quipped another.

How the old system worked vs. the new system

Since 1999, Australians who sold assets such as shares and investment properties after owning them for more than 12 months have only had to pay tax on 50 per cent of the profit they made.

That meant someone on the top marginal tax rate of 47 per cent effectively paid a maximum capital gains tax rate of 23.5 per cent.

But under Labor's new system, that automatic 50 per cent discount will disappear.

Instead, the government will adjust the original purchase price of an investment for inflation before working out the tax bill.

For example, if someone bought shares for $100,000 and later sold them for $200,000, they currently pay tax on half of the $100,000 profit, or $50,000.

But under the new rules, if inflation meant that original $100,000 investment would be worth $130,000 in today's dollars, they would pay tax on the 'real' $70,000 gain above inflation.

Treasury examples contained in Budget documents show someone earning a typical five per cent annual return on a $500,000 asset over 10 years would pay about $8,075 more tax under the new system compared to the current 50 per cent discount.

But investors earning very strong returns would be hit much harder.

Treasury said someone earning a 7.5 per cent annual return on the same investment over 10 years would pay an extra $58,851 in tax.

By contrast, investors whose returns barely outpace inflation could end up paying less tax than they do now because the inflation adjustment wipes out much of the taxable gain.

One Treasury example showed an investor paying nearly $25,000 less tax under the new rules because their investment only matched inflation.
