About MyStampDutyCalculator.com.au

Australia's independent, free, and accurate stamp duty calculator — built to help every property buyer make informed decisions with confidence.

flagOur Mission

MyStampDutyCalculator.com.au was created with a single, clear mission: to provide every Australian property buyer — whether purchasing their first home, upgrading, or investing — with fast, free, and reliable stamp duty estimates at their fingertips.

Buying property is one of the most significant financial decisions in life. Yet stamp duty (officially called "transfer duty" in most states) is often an afterthought, surprising buyers with costs they hadn't budgeted for. We set out to change that.

calculateWhat Our Calculator Does

lightbulbWhy We Built This Tool

We recognised that many existing stamp duty calculators were:

close Cluttered with real estate agent branding or referral links
close Outdated, using last financial year's tax thresholds
close Missing key factors like foreign buyer surcharges or FHB concessions
close Difficult to use on mobile devices

Our tool is completely independent — we have no affiliation with any real estate agency, bank, mortgage broker, or conveyancer. We do not earn referral fees for directing you to any service provider. Our only goal is to give you an accurate number so you can plan your finances with confidence.

scienceHow Our Calculations Work

Our calculator uses the official tax brackets, rates, and thresholds published by each state and territory's revenue authority. We reference the following official sources:

link NSW: Revenue NSW
link VIC: State Revenue Office Victoria
link QLD: Queensland Revenue Office
link WA: RevenueWA
link SA: RevenueSA
link TAS: State Revenue Office Tasmania
link ACT: ACT Revenue Office
link NT: Territory Revenue Office NT

Important: Our calculations are estimates for budgeting purposes only and do not constitute financial or legal advice. Tax rates and thresholds may change after a state budget. Always verify your final duty amount with the relevant state revenue authority or a licensed conveyancer.
