Australia: An update on the new GST withholding regime for the sale of residential premises

Last Updated: 23 August 2018
Article by Ian Miller

On 1 July 2018, the Treasury Law Amendment (2018 Measures No) Bill 2018 came into effect.
The Bill introduced changes affecting both vendors and purchasers of all residential property. It is particularly relevant to the sale and purchase of off-the-plan units and house and land packages.

As a result, it is now more important than ever to consider the GST implications when buying or selling residential real estate.

Executive summary

The major implications of these legislative changes are:

  • Vendors of all residential property must notify the purchaser whether the sale falls under the new GST withholding regime.
  • If so, the purchaser is required to withhold part of the purchase price on settlement and remit to the ATO.
  • Substantial penalties may apply to both purchasers and vendors for failure to comply.
  • The new rules apply to all residential property supplies made from 1 July 2018 (subject to some transitional provisions).
  • Contracts for sale/purchase must give special attention to these new rules. The Law Society 2018 Contract includes the relevant provisions.

Read on for a comprehensive summary of the changes and their practical implications.


Ordinarily, the sale of second-hand residential premises is "input-taxed", which means that the vendor is not required to collect GST on the sale.

However, the sale of new residential premises and potential residential land does not have the benefit of this exemption and therefore is normally subject to GST (ie a "taxable supply"), unless the vendor can show that the sale is not part of an enterprise which they carry on, or that he/she is neither registered nor required to be registered for GST.

Prior to 1 July 2018, purchasers would simply pay any GST to the vendor, and the vendor would be responsible for remitting the GST to the ATO when completing their quarterly Business Activity Statement (BAS).

The fundamental change introduced by the regime is that purchasers of new residential premises or potential residential land must now withhold a given amount on completion of the sale on account of GST and pay that sum to the ATO, rather than the developer. The withholding amount is then applied as a credit to the vendor's BAS.

It is important to note here that these changes do not introduce anything new to the application of GST to the sale of residential property. Rather, the changes are essentially a compliance measure, introduced in response to incidences of "phoenix activity", whereby unscrupulous developers were dissolving their businesses without lodging the required BAS.

The ATO's motive here is comparable to the Foreign Resident Capital Gains Withholding regime introduced in 2016. As is the case for that regime, these new rules essentially impose the role of tax collector on the purchaser, the vendor and their respective lawyers/conveyancers.

When is withholding required?

The new withholding regime applies to a taxable supply of the following (either by sale or "long-term lease"):

  • "new residential premises" (except those created through "substantial renovation" and "commercial residential premises") and
  • certain subdivisions of "potential residential land", where the subdivision does not contain any buildings used for a commercial purpose.

Whilst the meaning of these terms is already well-traversed in GST law, the application of them is not always straightforward. Legal advice should be obtained if there is any uncertainty as to whether a sale falls into either of these categories or whether the sale is indeed a taxable supply.

Generally, "new residential premises" are premises that have not previously been sold as residential premises and have not previously been the subject of a long-term lease. However, if the premises have been continuously leased for at least five years since construction, they will normally cease to be treated as "new".

At this point, it is important to note that the regime is not limited to sales by large-scale property developers, but can also apply to one-off projects, such as subdividing the backyard of the family home.

There are very limited exceptions to the withholding requirement (eg commercial residential premises such as hotels, new residential premises created by substantial renovations, and sales to GST-registered purchasers entitled to an input tax credit).

The withholding obligations

The new regime creates obligations on both the vendor and the purchaser.

As mentioned above, the core obligation under the regime is for purchasers to withhold part of the purchase price on settlement of the acquisition and remit that amount to the ATO. To be clear, this amount is not to be paid in addition to the purchase price but rather deducted from it.

The amount to be withheld on settlement is either:

  • 1/11th of the GST-inclusive contract price in most cases or
  • 7% of the contract price if the margin scheme applies or
  • 10% of the GST-exclusive market value if the supply is made between associates (eg for non-market value consideration).

Prior to this, however, the vendor (or "supplier") must give the purchaser a notification as to whether the purchaser is required to withhold. At this point, the supplier must also give the purchaser certain information required by the ATO when the purchaser makes the withholding payment.

If the purchaser is required to withhold, then the purchaser must complete and submit two forms to the ATO online:

  • Form 1 which notifies ATO of the sale. This can be given any time after entering into the contract but should be done as soon as possible.
  • Form 2 which notifies ATO of the settlement date. This can be lodged at or before completion of the sale.

Upon settlement, the purchaser must then make the withholding payment, normally by either cheque or, if setting electronically, via the PEXA platform.

Developers and other suppliers of new residential premises or potential residential land must consider the cash flow impacts of the GST component not being available on settlement. Foreign resident suppliers could also be subject to 12.5% withholding under the Foreign Resident Capital Gains Withholding regime.

Purchasers must consider the consequences of failing to withhold in light of the penalties which may apply.


There are substantial penalties applicable in the event of a failure by the supplier or the purchaser to meet their respective obligations.

Most notably, if a purchaser fails to pay the necessary withholding amount, he/she may be liable to a penalty equal to that amount.If a supplier fails to give the required notification to the purchaser, the supplier can be liable for penalties of up to $21,000 for an individual, or $105,000 for a corporation.

Importantly, a purchaser cannot blindly accept a supplier's notification that withholding is not required. On the contrary, a level of scepticism is required. If there are circumstances or disclosures in the contract which would make it unreasonable for the purchaser to believe that the supplier's notification is correct (eg if the property is clearly marketed as an off-the-plan unit or a house and land package), then the purchaser may still be liable for penalties for failing to withhold.

Transitional arrangements

The new withholding regime applies to all contracts entered into from 1 July 2018.

For contracts entered before this date, the regime will not apply if payment (other than a deposit) is made before 1 July 2020. This represents a grace period for contracts entered into prior to 1 July 2018.

Initial observations

The Law Society of NSW has responded by amending its standard contract for the sale/purchase of land to reflect these new obligations on both purchasers and vendors. In doing so, it has included an area for the supplier to complete the appropriate supplier notification.

Initial indications are that some purchasers and vendors are not entirely satisfied with the Law Society's standard conditions, and some are instructing their lawyers to draft special conditions which alter the standard withholding procedure.

Naturally, vendors want assurance that the ATO will promptly receive the withholding amount so that the appropriate credit is applied to their BAS. Purchasers, on the other hand, need assurance that they will be protected from penalties. Sound legal advice is required to balance these competing interests and find an appropriate solution.
