Western Australia has legislated a 75 per cent land tax exemption for eligible build-to-rent developments, the highest rate of any state. What it means for the rental pipeline and for builders active in the Perth market.

Western Australia’s parliament has passed legislation lifting the land tax exemption for eligible build-to-rent developments from 50 per cent to 75 per cent. Every other state offering a build-to-rent concession sits at 50 per cent. On that measure, WA now has the highest rate in the country.

The Land Tax Assessment Amendment (Build-to-Rent) Bill 2026 cleared parliament this week. The increased exemption applies to developments that become operational between 1 July 2025 and 30 June 2030. Eligible projects receive the 75 per cent exemption for the first 10 assessment years after completion, then revert to the existing 50 per cent rate for a further 10 years, giving a total concession window of 20 years.

To qualify, developments must meet existing eligibility criteria: at least 40 self-contained dwellings available on minimum three-year residential leases. Expansions to existing build-to-rent developments that become operational within the same window can also access the higher rate. If a development exits the build-to-rent model within the first 15 years, retrospective land tax applies for the years the exemption was received.

The government has put a concrete number on the savings. For land with an unimproved value of $10 million, the increased exemption is expected to deliver more than $1.5 million in savings over 10 years compared to the full rate with no concession.

How the Rate Compares Nationally

NSW, Victoria, Queensland and South Australia all offer a 50 per cent reduction in land value for eligible build-to-rent developments. WA’s 75 per cent rate sits above all of them.

The comparison is not entirely straightforward. NSW moved in its 2026 budget to extend its 50 per cent concession permanently, removing the previous end date of 2039. Victoria’s concession runs for up to 30 years. WA’s total window, at 20 years, is shorter than both. A developer building a long-run feasibility model will weigh rate against duration. On rate, WA leads. On longevity of the concession, NSW and Victoria offer a longer runway. Tasmania, the ACT and the Northern Territory currently offer no build-to-rent concession.

Every other state offering a build-to-rent concession sits at 50 per cent. WA’s 75 per cent rate is the highest in the country. Whether it stays the most competitive position over the long run depends on how investors model the trade-off between rate and duration.

Why Land Tax Is the Lever That Matters

Build-to-rent economics work differently to standard apartment development. In a build-to-sell project, the developer’s land tax exposure is temporary: once units are sold and titles transfer, the holding ends. In a build-to-rent model, the developer or a fund retains the entire building as a managed rental asset. Land tax is not a one-off cost. It is an annual line in the feasibility model for the life of the asset.

For institutional investors, the category most likely to back large-scale build-to-rent projects, that annual cost compounds over time. A 75 per cent exemption shifts the numbers materially, particularly on high-value urban sites in Perth where land values have risen sharply over the past three years.

The reform builds on the $75 million Build-to-Rent Kickstart Fund, covered by TGB when it launched in late 2025. That fund, administered through Keystart, offers low-interest finance to reduce the upfront capital burden on new rental developments. Together, the fund and the tax exemption address two of the main barriers that have historically slowed build-to-rent uptake in WA: access to debt capital and the ongoing tax drag on held assets.

WA’s Rental Market Context

The policy rationale is not hard to find. Perth’s rental vacancy rate has sat near historic lows through 2024 and 2025. Population growth, interstate migration and a constrained supply pipeline have pushed rents up and kept vacancy well below the 3 per cent threshold that signals a healthy market.

Build-to-rent is not a complete answer to that pressure. It targets a specific segment of the market: professionally managed, larger-scale apartment developments in well-located urban areas. It does not replace greenfield housing, social housing construction or planning reform. But it does represent an additional supply pathway that can attract private institutional capital, including superannuation funds and offshore property groups, into the rental market.

The broader picture of housing supply conditions across the country remains constrained. WA has been no exception. The tax settings now in place give developers a clearer investment case than they have had before.

What This Means for Builders

Build-to-rent is not the same as volume residential construction, and builders considering this space should understand what the model demands before pursuing tenders.

The party contracting a builder is also the party managing the building as a long-term asset. Finish quality expectations and defect tolerances reflect that. Handover documentation requirements are typically more rigorous than on comparable build-to-sell apartment projects. For builders already operating to high standards, it is a natural fit. For those used to looser developer relationships, the adjustment is real.

The pipeline opportunity is genuine. As new projects work through investment committee and development approval, construction tenders will follow. The 30 June 2030 operational deadline for accessing the 75 per cent rate sets a meaningful clock. For developers to qualify, construction needs to be underway soon enough to allow for planning approval, design development, procurement and build. That window is workable, but not open-ended.

Builders with experience in multi-residential and apartment delivery, particularly those with established relationships in Perth’s inner suburbs, should be watching this space. The WA build-to-rent sector was already gaining momentum before this legislation passed. The tax settings now give investors a firmer foundation to commit.

FREQUENTLY ASKED QUESTIONS

What is the build-to-rent land tax exemption in Western Australia?

The WA build-to-rent land tax exemption reduces the taxable land value for eligible rental developments, lowering the annual land tax bill for investors who retain and operate the development as long-term rental housing. The exemption now sits at 75 per cent for the first 10 years after completion, then reverts to 50 per cent for the following 10 years, giving eligible projects a 20-year concession window in total.

How does WA’s build-to-rent concession compare to other states?

NSW, Victoria, Queensland and South Australia all offer a 50 per cent land tax reduction for eligible build-to-rent developments. WA’s 75 per cent rate is the highest in the country. The comparison is not straightforward on duration, though: NSW has extended its 50 per cent concession permanently, and Victoria offers up to 30 years. WA’s 20-year total window is shorter than both, so investors modelling long-run returns will weigh rate against longevity. Tasmania, the ACT and the Northern Territory currently offer no build-to-rent concession.

What developments qualify for the 75 per cent land tax exemption in WA?

To access the increased exemption, a development must become operational between 1 July 2025 and 30 June 2030. It must also meet the existing eligibility criteria: at least 40 self-contained dwellings available on minimum three-year residential leases, owned and managed by the same entity. Expansions to existing build-to-rent developments that become operational within the same window can also qualify. Land used for non-residential purposes within a development, such as offices, is excluded from the exemption, though facilities available to residents such as gyms are included.

How long does the WA build-to-rent land tax exemption last?

The total concession window is 20 years. Eligible developments receive the 75 per cent exemption for the first 10 assessment years after completion. After that, the exemption drops to 50 per cent for the following 10 years. If a development exits the build-to-rent model within the first 15 years, retrospective land tax applies for the years the exemption was received.

What is the WA Build-to-Rent Kickstart Fund?

The $75 million Build-to-Rent Kickstart Fund is a separate WA government initiative administered through Keystart. It offers low-interest and no-interest finance to developers to reduce the upfront capital burden on new build-to-rent projects and improve project feasibility. The expression of interest process for the fund has now closed. The fund works alongside the land tax exemption to address two of the main barriers to build-to-rent development in WA: access to debt capital and ongoing tax costs.
