Land Tax Changes and What Interstate Investors Need to Know

Perth's property market has never been hotter for interstate investors. With median prices hovering around $680,000 and vacancy rates below 1%, rental yields remain among the strongest in the nation. But for investors based in Sydney, Melbourne or Brisbane, recent Western Australian land tax adjustments are creating a new layer of complexity that demands attention before committing capital.

Land tax in WA applies to investors holding multiple properties or those buying investment stock outright. From 1 July 2026, the threshold at which land tax becomes payable has shifted, catching many interstate operators off-guard. For non-residents purchasing in high-growth corridors like Joondalup and Wanneroo—where apartment blocks and townhouse developments are booming—the implications are material.

"The key change affects properties valued above the new threshold," explains the principle simply: interstate investors now need to factor land tax into their yield calculations from day one. A typical $450,000 apartment in Joondalup's central precinct, which might gross 4.5 to 5 per cent in annual rental income, will now carry an additional tax liability that wasn't previously factored in by many Melbourne or Sydney-based buyers doing remote due diligence.

Consider a concrete example. An investor purchasing a two-bedroom townhouse on Lakeside Drive in Joondalup for $520,000 would expect gross rental yield of approximately $24,000 annually. Under the revised thresholds, land tax could add $800–$1,200 per year to holding costs, depending on the property's unimproved land value. For interstate investors juggling portfolios across multiple states, that's a meaningful erosion of net yield.

The impact varies by location. Established suburbs like Nedlands or Dalkeith, where unimproved land values are higher, will see steeper tax bills than emerging growth zones. However, growth suburbs still offer superior yields despite the tax hit—a crucial point for yield-focused investors priced out of eastern capitals.

WA's Property Council and tax advisers recommend interstate buyers engage a local accountant before settlement. The calculation of unimproved land value—the basis for tax assessment—can surprise investors unfamiliar with WA's methodology. Some properties in Wanneroo's new estates, for instance, have unimproved values significantly lower than purchasers anticipate, offering a silver lining.

The broader message: Perth remains genuinely attractive for interstate capital. But the tax environment has shifted. Investors who factor the new thresholds into their modelling upfront will make smarter acquisition decisions and avoid the shock of unexpected annual bills. In a market this tight, that discipline separates winners from disappointed latecomers.
