Land tax is one of the more underappreciated compliance obligations affecting property investors, yet the bookkeeping errors it generates — particularly around trust structures and commercial leases — are common enough to warrant a dedicated treatment. Here is what every bookkeeper advising property clients in Australia needs to have across.
What Land Tax Is and Who Administers It
Land tax is an annual state and territory tax on the unimproved capital value (UCV) of land that is not a principal place of residence. There is no federal land tax in Australia — it is administered entirely at the state and territory level, which means rates, thresholds, exemptions, and assessment dates vary significantly across jurisdictions.
Key features by state:
- New South Wales: assessed on 31 December each year; threshold approximately $1,075,000 (2026); principal place of residence exempt; primary production land exempt under certain conditions.
- Victoria: assessed on 31 December; threshold $300,000 (2026) for individuals; discretionary trust holdings assessed with no threshold (see below).
- Queensland: assessed on 30 June; threshold $600,000 for individuals; companies and trustees assessed at higher rates.
- South Australia: no threshold for companies and trusts.
The thresholds aggregate across all assessable land holdings within the relevant state — a taxpayer holding three investment properties in NSW may exceed the threshold when the combined land values are aggregated, even if each individual property falls below it. Bookkeepers advising clients who acquire additional properties mid-year should model the land tax impact on the combined portfolio.
Deductibility for Income Tax Purposes
Land tax is deductible under s.8-1 of the ITAA 1997 to the extent the relevant land is used for income-producing purposes. For an investment property generating rental income, the full land tax assessment is deductible in the year it is paid (or accrued, under the accruals method).
Apportionment is required where land is only partially used for income production. A property that is owner-occupied for part of the year and tenanted for the remainder must apportion the land tax deduction based on the proportion of income-producing use — typically calculated on a time basis (days available to rent divided by total days in the assessment year).
Land tax on vacant land held for future development is not immediately deductible. Where the land is not generating assessable income, no s.8-1 deduction is available. The land tax becomes part of the cost base of the land for CGT purposes under s.110-25, and the deduction is effectively deferred until the CGT event.
Land Tax on Trust-Held Property: The No-Threshold Trap
The most significant practical trap in land tax for bookkeepers is the treatment of discretionary trust holdings. In Victoria, NSW, and South Australia, discretionary trusts that hold investment property are assessed for land tax without the benefit of the individual threshold that would apply if the same individual held the property directly.
In Victoria, for example, an individual investor holding a $400,000 land value investment property pays no land tax (below the $300,000 threshold). The same property held in a family discretionary trust is assessed in full at the trust rate from the first dollar. Depending on the trust's total land holdings, this generates a meaningful annual charge that must be budgeted.
Bookkeepers advising clients with property-holding trusts should calculate the effective land tax exposure on all trust land holdings in each relevant state and ensure it is factored into the trust's annual cash flow. Trustees who are blindsided by land tax assessments — and who cannot meet the assessment from trust income — create cash flow and compliance problems that could have been avoided with adequate planning.
Victorian Surcharge Land Tax on Foreign Owners
Victoria imposes an additional surcharge land tax on foreign persons (non-Australian citizens or non-permanent residents) who hold residential land in Victoria. As at 2026, the surcharge rate is 4% per annum, applied on top of the general land tax. This affects foreign nationals who hold Victorian residential investment property directly or through certain trust and company structures where a foreign beneficiary or shareholder exists.
The definition of "foreign person" for Victorian land tax surcharge purposes broadly follows the FIRB definition in the Foreign Acquisitions and Takeovers Act 1975. Bookkeepers servicing clients with international connections should check whether any residential property held in Victoria triggers the surcharge. The surcharge applies annually and is a separate charge on the same assessment notice as the general land tax.
Land Tax Recovery in Commercial Leases
Commercial property is subject to land tax at the same state-administered rates. A common lease arrangement is for the landlord to include a "land tax recovery" clause that allows the landlord to recover a proportion of the annual land tax from the commercial tenant as part of outgoings.
This recovery is assessable income for the landlord — the receipt of a reimbursement from the tenant is a taxable receipt in the same way as the underlying rent. The original land tax assessment remains deductible against that income. The net effect is tax neutral, but both the income (landlord receives land tax recovery from tenant) and the deduction (landlord pays the land tax assessment) must be recorded. Failing to bring to account the recovery as income — while claiming the deduction — creates an understated income position on the landlord's return.
