First home owners can only get concessions if the property value is $450,000 or less for vacant land; $700,000 or less for homes in the metropolitan or Peel regions; or $750,000 or less for homes outside those regions.

New duty rates apply to first home owners based on the property value and location.

Taxpayers entering multi-tiered or single-tiered schemes must meet specific time periods to get concessions.

Duty concessions for pre-construction and under-construction agreements now depend on specific value thresholds.

The Commissioner can reassess duty for first home owner or off-the-plan transactions if the original assessment happened before the law started.

Off-the-plan agreements are considered complete when the purchaser becomes the legal owner.
