What this site does

LandTaxCalculator.com runs two purpose-built calculators, each tailored to its country’s property-tax system:

• Australia land tax calculator — for the annual state-level tax that Australian property owners pay on the unimproved value of their land holdings above a threshold. Covers all 8 states and territories, with separate treatment for individuals, companies, trusts, and foreign owners.
• Canada land transfer tax calculator — for the one-time tax that Canadian home buyers pay on closing, calculated as a percentage of the purchase price. Covers all 10 provinces, plus the Toronto Municipal Land Transfer Tax (including its April 2026 luxury brackets) and Montreal’s welcome tax.

Both calculators are free, load instantly, and run entirely in your browser. No signup, no email capture, no tracking. You can use them once and never come back, or bookmark them for every property you evaluate. Either way, the price stays zero.

Why we built this

Property taxes are the largest line item in most closing statements, and often the most misunderstood. A buyer in Toronto might pay $32,950 in combined land transfer tax on a $1 million home — more than three years of annual property tax on the same property. A Sydney investor might pay $15,000+ in annual land tax on an investment portfolio that seemed to be doing fine on paper. Getting these numbers wrong is expensive; getting them approximately right, early in the process, changes which offers you make.

Yet the online calculators we found before building this one had consistent failings: outdated rates (often three to five years stale), aggressive email capture before showing results, ads weighting the page above the fold, confusing UI that obscured which state or province was being used, and — most importantly — no link back to the government source so you could verify the calculation yourself.

So we built the thing we wanted to use. Fast, ad-free, rate-accurate, and transparent about its math.

How we verify rates

Every rate in both calculators is pulled from the relevant government source — not a third-party summary, not a blog, not an aggregator. That means:

• Australia: Revenue NSW, State Revenue Office Victoria, Queensland Revenue Office, RevenueWA, RevenueSA, Tasmanian State Revenue Office, ACT Revenue Office, and NT Department of Treasury and Finance.
• Canada: Ontario Ministry of Finance (ontario.ca), City of Toronto (toronto.ca), Government of BC (gov.bc.ca), Ville de Montréal (montreal.ca), Manitoba Finance, Service Alberta, and the remaining provincial Land Titles authorities.

Before any calculator is released, it’s tested against the official worked examples published by these governments. Ontario.ca’s $300,000 worked example (which comes to $2,975). Montreal.ca’s $700,000 example (which comes to $9,349). gov.bc.ca’s $3.4 million example (which comes to $88,000). Our calculators match these to the dollar — and if they don’t, they don’t ship.

What we update, and when

Rates move on three predictable schedules and one unpredictable one:

• Annual budget announcements (typically February to May depending on jurisdiction) — where most threshold indexing is announced.
• January 1 indexing — Quebec welcome tax brackets, many Australian land tax thresholds, and CPI-linked adjustments roll over on this date.
• Mid-year rate changes — occasional but meaningful. Toronto’s April 2026 luxury MLTT brackets are a recent example, as was BC’s 2024 threshold doubling for first-time buyers.
• Ad-hoc legislation — less predictable; typically foreign-owner surcharges or one-off surtaxes during housing policy shifts.

When rates change, the calculators are updated as soon as the official source publishes the new figures — usually the same day or the next.

What this site is not

It’s worth being clear about the boundaries:

Not tax advice

Calculations are estimates for general information. Your actual liability depends on circumstances a calculator can’t see — exemptions, concessions, ownership structures, interstate aggregation rules, dates of registration, and more.

Not legal advice

If you’re about to commit hundreds of thousands of dollars on the strength of a closing-cost estimate, confirm the figure with your accountant (Australia) or real estate lawyer (Canada) before closing.

Not a replacement for government tools

Every province and state has an official calculator. Ours is faster and clearer — theirs is authoritative. Use both.

Not an ad-supported product

There are no ads on the site, no affiliate links embedded in results, and no partnerships influencing which calculations you see. If that changes, it will be disclosed clearly.

If a rate looks wrong, a worked example fails, or a bracket doesn’t match your government source, get in touch. Corrections with a link to the official source are especially appreciated — they let us verify, fix, and re-test on the same day.
