Windfall Gains Tax Explained for Victorian Buyers

By the Pearson Chambers Conveyancing.
Published 25th April 2026

We get asked this all the time by buyers looking at blocks on Melbourne's fringe, house and land packages, or small acreages where the agent says the land was 'recently rezoned'. The worry is usually the same: if the land carries a Windfall Gains Tax issue, does that become your problem when you settle?

The short answer: Windfall Gains Tax is a Victorian tax on the increase in land value caused by a rezoning, and it applies to rezonings that took effect from 1 July 2023. Most ordinary Melbourne home buyers never run into it because up to 2 hectares of eligible residential land is exempt, and rezonings to or from the Urban Growth Zone within the GAIC area are excluded. The real risk for buyers is vacant or recently rezoned land outside those settings, especially where tax has been deferred or is still waiting to be assessed.

What is Windfall Gains Tax, and when does it apply?

Windfall Gains Tax applies when a rezoning lifts the value of land by more than $100,000. It is triggered by the rezoning itself, not by the later sale, build, subdivision, or development.

That timing matters. The person who owns the land when the rezoning takes effect is the one assessed for the tax. In Victoria, the rezoning takes effect when the planning scheme amendment is approved and published in the Victorian Government Gazette, unless the notice sets a different start date.

For buyers, that means a block isn't hit with WGT just because prices have gone up or because the suburb has become more popular. A Coburg weatherboard or a townhouse in Reservoir is not suddenly caught just because the market moved. There needs to have been a qualifying rezoning.

The other point that catches people out is that not every planning change counts. If the land stays in the same zone and only the schedule changes, that is not treated as a rezoning for WGT purposes. So the question is not simply, 'Has the planning changed?' It is, 'Has this land actually moved from one zone to another, and did that happen on or after 1 July 2023?'

In plain English, think of WGT as a rezoning tax, not a sale tax. If the land became more valuable because the government changed what could be done with it, the tax rules may step in. If the land has been in the same relevant zone for years, WGT is usually not the issue.

We've had clients come to us in a panic after hearing the phrase 'windfall gains tax' at an inspection, only for the real answer to be much simpler: the land had been residential long before 2023, so WGT was never on the table.

How is Windfall Gains Tax worked out?

The tax is based on the uplift in value caused by the rezoning. In practice, that means the difference between the land's capital improved value before the rezoning and after the rezoning, as determined by the Valuer-General.

The rate bands are where buyers and sellers usually stop and pay attention:

• No tax applies to the first $100,000 of uplift.
• If the uplift is between $100,000 and $500,000, 62.5% applies to the amount above $100,000.
• If the uplift is $500,000 or more, 50% applies to the full uplift.

That last point is a big one. Once the uplift reaches $500,000, the 50% rate applies to the whole uplift, not just the amount above the threshold.

A simple example helps. Say a block near Gisborne is rezoned and the uplift is assessed at $400,000. Only $300,000 is taxed, so the WGT would be $187,500. If the uplift is $600,000, the whole $600,000 is taxed at 50%, so the WGT becomes $300,000.

For most everyday buyers, the calculation itself is not the hardest part. The harder part is working out whether there was a qualifying rezoning, whether an exemption applies, and whether any unpaid or deferred amount is still tied to the land. That is why a good conveyancing check matters more than doing back of the envelope maths on the tram ride home from an inspection.

Does Windfall Gains Tax apply to my Melbourne home?

Usually, no. Most standard Melbourne homes are covered by the residential land exemption, which exempts up to 2 hectares of eligible residential land per planning scheme amendment for the same owner or related owner group.

That covers far more than just a principal place of residence. Eligible residential land can include an owner occupied home, an investment property, a holiday house, and even primary production land with a residence on it, provided it fits the statutory definition.

The two big watch-outs are size and vacancy.

If the land is more than 2 hectares, only the first 2 hectares are exempt. The balance can still be taxed. And the owner does not get to choose which 2 hectares are exempt. The value uplift is apportioned mechanically by size.

If the land is vacant, the residential exemption does not apply. That is the point many first home buyers miss when they move from looking at established homes to looking at vacant blocks in outer suburban or regional fringe areas. A house on a small block in Sunshine West is one thing. A bare lot in a freshly rezoned pocket outside the main growth corridor is another.

That is why the answer is often different for:

• an existing home in Preston
• a townhouse in Brunswick East
• a semi-rural property with a dwelling near the urban fringe
• a vacant block being marketed as a future build site

Most buyers of established Melbourne homes can take a breath. Most buyers of vacant or fringe land should slow down and check the paperwork properly.

What happens in Melbourne's growth corridors?

A lot of growth corridor land is carved out of WGT because of the GAIC rules. Rezonings to or from the Urban Growth Zone within the GAIC area are excluded from Windfall Gains Tax.

That is especially relevant in the municipalities buyers ask us about all the time: Cardinia, Casey, Hume, Melton, Mitchell, Whittlesea and Wyndham. If you are buying in places like Tarneit, Wollert, Officer, Mickleham or Cranbourne South, the WGT question often turns into a GAIC question instead.

That does not mean buyers should stop checking. It means you need to check the right thing.

In those areas, your conveyancer will usually look at whether the land sits in the GAIC contribution area and whether the relevant rezoning is one of the excluded UGZ rezonings. A buyer should not assume 'growth area' always means 'no issue'. It often means the issue sits under a different label.

Outside those areas, the WGT risk becomes more real. We tend to see the sharper questions on:

• vacant land on the peri-urban fringe
• regional fringe blocks that have recently shifted from farming or rural zoning toward residential use
• sites with a developer history or subdivision plan in the background
• small acreages where part of the sales pitch is future development upside

That is why a buyer in Carlton usually worries about owners corporation records and heritage overlays, while a buyer on the edge of Geelong, Gisborne or Bass Coast may need a much closer look at rezoning history and tax charges.

Can the vendor pass Windfall Gains Tax on to me as the buyer?

Not if it is a known liability. Since 1 January 2024, Victorian vendors cannot pass a known WGT liability onto a purchaser under the contract of sale or an option agreement.

A known liability means the assessment has already been issued and served before the contract is signed. If the tax is known in that sense, any clause making the buyer pay all or part of it is void, and including such a clause is an offence.

If you want a broader plain English summary of the 2024 apportionment rules, the key point for buyers is simple: a seller cannot use the contract to dump an already assessed WGT bill on you.

But there is still a grey area buyers need to understand. The ban is about known, assessed liabilities. It does not wipe away every WGT risk connected to land.

Two situations still deserve attention:

1. Deferred WGT
   An owner can defer payment of WGT, with interest, for up to 30 years or until a cessation event. If deferred tax is secured against the land, it can become very relevant at settlement.
2. WGT that is not yet assessed
   A rezoning may already have happened, but the SRO may not yet have issued the assessment. That can leave a buyer exposed if they have not done the right pre-contract checks.

In our practice, this is where the real buyer anxiety sits. It is rarely the dramatic contract clause everyone imagines. More often, it is a quiet issue buried in the tax status of the land, especially with vacant sites and fringe blocks.

How does a conveyancer check Windfall Gains Tax before you sign?

The main tool is a property clearance certificate from the State Revenue Office. If there is one document buyers should remember from this topic, it is that one.

A property clearance certificate can show:

• WGT that is due and unpaid
• WGT that has been deferred, including accrued interest
• WGT that has been assessed but is not yet due
• a WGT event where tax is still yet to be assessed

That last category is the one people often miss. If the certificate says WGT is yet to be assessed, the usual buyer protection cap does not apply. In other words, a clean looking settlement story can still turn messy if the land has already had the rezoning event and the tax has not been worked out yet.

The current application fee is $19.50, and certificates are often issued quickly, though some can take longer.

There are three practical points buyers should know:

1. Order your own certificate

A purchaser should get their own certificate. You should not rely on one the vendor obtained. That protection is tied to the buyer obtaining the certificate themselves.

2. Read the result, not just the headline

A certificate can show more than a simple yes or no. Deferred amounts, accrued interest, and 'yet to be assessed' notes matter. A conveyancer reads those lines very differently from the average buyer glancing at a PDF late at night.

3. Check the tax position alongside the contract documents

The certificate is one piece of the puzzle. A careful conveyancer will also:

1. review the Section 32 vendor statement for any reference to rezoning, WGT, deferred tax, or unusual disclosures
2. check the title and planning history
3. raise requisitions if the tax position is unclear
4. consider a special condition if there is a live risk that needs to be dealt with before settlement

We've seen this come up most often where a buyer is moving fast, the sales pitch leans heavily on future development potential, and no one has paused to ask whether a rezoning has already created a tax charge on the land.

What should first home buyers check before signing?

The best approach is boring, and that is a good thing. Slow down, check the paper trail, and do not let the sales talk race ahead of the legal checks.

Here is the shortlist we use with Melbourne buyers:

• Has the land actually been rezoned on or after 1 July 2023?
  If not, WGT may drop out straight away.
• Is it vacant land or land with a residence already on it?
  Vacant land does not get the residential exemption.
• Is the parcel under or over 2 hectares?
  If it is over 2 hectares, only part may be exempt.
• Is it in one of the GAIC municipalities?
  If so, the question may be whether the rezoning is excluded from WGT because it is to or from the Urban Growth Zone within the GAIC area.
• Does the Section 32 mention rezoning, tax liabilities, or anything unusual?
  Silence is not always reassurance. Sometimes it just means you need another document.
• Has your conveyancer ordered a property clearance certificate in your name?
  That is one of the cleanest ways to flush out deferred or assessed WGT issues.

This is especially worth doing before an auction. Once the contract is signed, you want your diligence already done. Buyers looking at fringe estates, acreage, or regional land should be even more careful, because that is where the WGT questions tend to get more serious.

Frequently asked questions

What is Windfall Gains Tax in Victoria?
Windfall Gains Tax is a Victorian tax on the increase in land value caused by a rezoning. It applies to rezonings that took effect from 1 July 2023 and is assessed against the owner of the land at the time the rezoning happens, not the later buyer.

Does Windfall Gains Tax apply to my home?
Usually not. Up to 2 hectares of eligible residential land is exempt, which covers most established Melbourne homes. The bigger risk is vacant land, because vacant land is not eligible for the residential exemption.

Can a vendor charge me Windfall Gains Tax as the buyer?
A vendor cannot pass on a known WGT liability under a contract signed on or after 1 January 2024. A known liability means it has already been assessed and served before the contract is signed, and any clause trying to shift that liability is void.

How much is Windfall Gains Tax in Victoria?
No tax applies to the first $100,000 of uplift. Between $100,000 and $500,000, 62.5% applies to the amount above $100,000, and at $500,000 or more, 50% applies to the full uplift. The Valuer-General determines the before and after values.

What is a property clearance certificate for Windfall Gains Tax?
It is an SRO certificate that shows whether WGT is due, deferred, assessed but not yet due, or still yet to be assessed for the land. Buyers should obtain their own certificate, because that is what gives them the statutory protection cap if a charge is shown.

Does Windfall Gains Tax apply in Melbourne's growth corridors?
Often no, because rezonings to or from the Urban Growth Zone within the GAIC area are excluded from WGT. That is why growth corridor purchases often need both a WGT check and a GAIC check.

Can Windfall Gains Tax be deferred?
Yes. An owner can defer all or part of a WGT liability, with interest, for up to 30 years or until a cessation event. That matters for buyers because deferred tax can remain tied to the land and affect settlement or a later transfer.
