Frequently asked questions

Does $450,000.00 in Western Australia qualify for a first-home concession?

Price alone does not establish eligibility. Buyer history, occupancy, property type and the rules at the contract date can matter. Confirm your circumstances with the revenue office before relying on a reduced amount.

Does this include every purchase cost?

No. Transfer duty is only one part of the budget. Conveyancing, inspections, registration, lender costs and any applicable foreign-buyer surcharge need separate consideration.

Can I use another state's duty result for this purchase?

No. This page uses Western Australia rules. Other jurisdictions have different schedules and concessions; use the state comparison as a comparison, not a substitute for the applicable rules.
