Estimate 2026-27 ACT land tax for houses and unit-title properties using current AUV rates and the separate unit entitlement method.
Tax = Base amount (per threshold) + (Land value − Threshold) × Marginal rateInputs
Use your property’s state or territory to apply local thresholds and rates.
ACT unit-title properties use a separate valuation-charge apportionment method.
For an ACT house, use this property's five-year average unimproved value. Do not use the market price.

Land Tax by State Comparison
Important assumption
This estimate applies published land-tax brackets to the taxable land value entered. It does not calculate foreign-owner surcharge land tax, Victorian absentee-owner surcharge, WA Metropolitan Region Improvement Tax, vacant residential land tax, settlement adjustments, exemptions or concessional land classes.
The state bars are not like-for-like liabilities. Valuation dates, aggregation rules and ownership definitions differ. ACT uses each property's five-year average unimproved value and has separate unit-title apportionment, so do not compare its bar with an aggregate holding value entered for another state.
Check the relevant revenue office before relying on an estimate: Revenue NSW, SRO Victoria, Queensland Revenue Office, RevenueWA, RevenueSA and ACT Revenue Office.

ACT land tax source notes
Checked 25 August 2026. This page provides a general estimate only; official assessments can vary with exemptions, ownership structure, valuation rules and surcharges.
- From 1 July 2026, ACT land tax includes a $1,778 fixed charge plus a marginal valuation charge based on average unimproved value.
- For a unit-title property, the valuation schedule applies to the residential AUV of the whole complex before the result is apportioned by unit entitlement.
- ACT assesses whole quarters using the property status at 1 July, 1 October, 1 January and 1 April. This calculator reports a full-year guide.
Unit owners should read the ACT unit-title land tax worked example before entering a complex AUV or unit entitlement.
