How it works
Methodology & disclaimers
DutyStack is a free consumer calculator for stamp duty and funds to complete. It is not a broker lead service and does not sell products on this site.
What we calculate
Stamp duty, foreign surcharges where applicable, typical government fees, FHB concessions, FHOG eligibility notes, deposit scenarios (5% Scheme / 10% / 20%), LVR, and an LMI applicability flag. We never invent an LMI premium dollar amount.
Rate table version: 2026-07-ftc. When legislation changes, we ship a new version. Always verify with the state revenue office before you buy.
What this is not
- Not credit advice under the NCCP
- Not a Revenue Office assessment or settlement quote
- Not a lead form — we do not ask for your contact details to run the calculator
