Common questions
What others asks before signing up?
How much is stamp duty in NSW, VIC and QLD?
Stamp duty (transfer duty) is a state tax based on your property's dutiable value. As a rough guide, a $750,000 purchase costs around $28,800 in NSW, $40,070 in VIC (investor) and $19,600 in QLD (owner-occupier). Enter your details above for an instant estimate — the final figure is confirmed by your broker or conveyancer.
Do first home buyers pay stamp duty?
Often not. NSW exempts eligible first home buyers up to $800,000, VIC up to $600,000, and QLD charges no duty on homes up to $700,000 — and no duty at any price on a brand-new first home from 1 May 2025. This calculator applies the right concession automatically to produce your estimate.
How accurate is this stamp duty calculator?
It uses the current 2025-26 transfer duty brackets published by Revenue NSW, the Victorian SRO and the Queensland Revenue Office. It produces an estimate — your broker or conveyancer confirms the final figure after reviewing your circumstances, as concessions and surcharges can vary.
Is the foreign buyer surcharge included?
Yes. The calculator adds the foreign purchaser surcharge where relevant — 9% in NSW and 8% in VIC and QLD — on top of standard duty.
Can I add this calculator to my website?
Yes. Embed it on WordPress, Webflow, Squarespace, Wix or Shopify with a single snippet, or share your free Leadkit-hosted page if you don't have a site.
What do I get when a buyer uses it?
Every submission lands in your dashboard as a lead with the buyer's contact details, property value, state and a stamp duty estimate — plus an automatic branded email to you and the buyer.
Is Leadkit really free?
Yes. Free lets you add up to 3 calculators to your website and receive 10 leads per month — no credit card. Every lead beyond the cap is still captured and held for you; upgrading to Pro ($29/mo) opens them all retroactively and removes the cap.
Do I need to know how to code?
No. You get an embed code (one line of HTML). Paste it into your website builder — Wix, Squarespace, WordPress, or any custom site. That's it.
How accurate are the price estimates?
You configure the calculator formulas to match your actual pricing. Leadkit provides the framework; you set the numbers. Estimates can be as detailed or as rough as you like.
What happens with lead data?
All lead data is stored securely in your workspace. You own it. We never sell or share your leads with anyone.
Can I use Leadkit as an agency for multiple clients?
Yes — our Agency plan lets you create and manage separate workspaces for each of your clients, all from one dashboard.
What's the difference between the plans?
Free: up to 3 calculators, 10 leads/month (over-cap leads held + locked until upgrade). Pro: unlimited leads, unlimited calculators, white-label, branded email sending, analytics, email templates. Agency: everything in Pro plus multi-workspace management.

How it works
How your stamp duty estimate is calculated
This calculator applies each state's published transfer duty brackets to your property value, then adjusts for owner-occupier and first home concessions and any foreign purchaser surcharge. It produces an estimate, not a binding quote.
GST handling: Stamp duty is itself a state tax — GST does not apply to transfer duty.
1
Find your state's duty brackets
NSW, VIC and QLD each set their own progressive transfer duty scale. We apply the bracket rates to your property's dutiable value.
duty = sum(bracket_portion × bracket_rate)
2
Apply owner-occupier concessions
Victoria offers concessional principal-place-of-residence rates up to $550,000, and Queensland a home concession on the first $350,000 for owner-occupiers.
3
Apply first home buyer concessions
Eligible first home buyers receive exemptions or reductions — a full NSW exemption to $800k, VIC to $600k, and no QLD duty to $700k (any price for a new first home).
final_duty = max(0, base_duty − concession)
4
Add any foreign purchaser surcharge
Foreign buyers pay an extra 9% (NSW) or 8% (VIC, QLD) of the property value on top of standard duty.
Indicative transfer duty for an owner-occupier (not a first home buyer) at common price points. First home and foreign buyer adjustments change these figures.
Sydney and Melbourne purchases sit at the higher end given median prices above $1M; regional NSW, VIC and QLD purchases typically fall in lower brackets. First home and new-home concessions can reduce duty to nil.
