Small and medium sized businesses strongly oppose a Capital Gains Tax, according to industry research conducted in March.
MYOB's annual business monitor shows 67 per cent of the 1000 small businesses surveyed said they were against the Tax Working Group's proposal.
Around 48 per cent of those surveyed said they were strongly against the proposed introduction of a tax on profits made from the sale of assets including land, shares, investment property, business and intellectual property.
An additional 19 per cent said they were against the proposal.
Just 20 per cent of small firms said they supported it.
