How is the levy calculated?

The levy is applied at 0.25% of the estimated project value, as defined under the Act.

• If your project received Development Approval or started construction BEFORE 1 January 2025:
  The levy is calculated on the estimated project value of building or construction works greater than $40,000 (inc. GST).
• If your project received Development Approval or started construction AFTER 1 January 2025:
  The levy is calculated on the estimated project value of building or construction works greater than $100,000 (excl. GST).

Where there is no construction contract, or the work is carried out by an owner-builder:
The estimated project value is the reasonable market value of the building or construction work and materials required, in accordance with Schedule 1A of the Act. This includes labour, materials, subcontracted works and other costs that would ordinarily form part of a commercial construction contract.
