The ACT will become the first state or territory to abolish stamp duty for first home buyers in the centrepiece measure of a housing-centric budget.
Set to be unveiled in the territory budget on Wednesday, exemptions will be extended to every resident entering the property market from July 1.
Currently, only homes under $1 million are exempt and purchasers must be below income eligibility thresholds.
"It's the result of a long-term plan to remove what is an inefficient and unfair tax, whilst, of course, continuing a progressive removal of stamp duty across the entire system," Chief Minister Andrew Barr told ABC Radio.
Stamp duty will also be dumped for pensioners, some National Disability Insurance Scheme recipients, anyone who has not owned a property for five years and owner-occupiers purchasing new builds.
