Many property investors who hold residential real estate inside a family trust wonder whether they need to register their trust for GST. It is a fair question, trusts can be complex, and the GST rules around property are some of the most misunderstood in Australian tax law.

The short answer is: in most cases, no. A family trust that earns only residential rental income does not need to register for GST. But there are exceptions, and getting this wrong can create compliance headaches with the ATO. This article explains when GST registration applies, and when it does not, for a family trust holding residential investment property.

At Pinnacle Accounting & Advisory, we work with Melbourne property investors and business owners who use family trusts to hold and grow their asset portfolios. Understanding how GST interacts with your trust structure is an important part of managing your obligations correctly.

What Is Residential Rent for GST Purposes?

Residential rent is the income a landlord receives from renting out residential premises, a house, apartment, unit, or townhouse used for accommodation. Under the GST Act, this type of supply is specifically classified as an input-taxed supply.

Input-taxed does not mean exempt in the traditional sense. It is a specific GST treatment with two consequences:

• The landlord does not charge GST on the rent
• The landlord cannot claim GST credits (input tax credits) on expenses related to the property, such as property management fees, repairs, and maintenance

This applies whether the landlord is an individual, a company, or a family trust. The legal entity holding the property does not change how the rent is classified for GST purposes.

The GST Registration Threshold and Rental Income

Businesses with a GST turnover of $75,000 or more per year are generally required to register for GST. Many landlords with high rental income assume this threshold means they need to register, particularly if their property generates $75,000 or more in annual rent.

However, the threshold only applies to taxable supplies. Because residential rent is an input-taxed supply, it does not count toward the $75,000 GST registration threshold.

This means a family trust that earns only residential rental income, even if that income exceeds $75,000 per year, is generally not required to register for GST. The ATO confirms this position: residential rent is not subject to GST.

When a Family Trust Does Need to Register for GST

There are several situations where a family trust holding residential property might need to register for GST, or where the GST treatment becomes more complex. These are worth understanding before assuming you are in the clear.

The Trust Has Other Business Income

If the family trust conducts business activities beyond residential property rental, for example, running a trading business, providing services, or holding commercial property, those activities may generate taxable supplies. If the combined taxable supplies from those other activities reach $75,000 or more per year, the trust must register for GST.

Once registered, the trust must charge GST on its taxable supplies and lodge BAS returns. However, the residential rent component remains input-taxed. The trust cannot claim GST credits on rental property expenses just because it is registered for GST in relation to a separate business activity.

The Trust Sells a New Residential Property

This is the most commonly overlooked exception. If the family trust sells new residential premises, a property that has never been sold as a residential premises before, or one that has been substantially renovated, the sale is generally a taxable supply for GST purposes.

A substantially renovated property is one where the renovations have removed or replaced substantially all of the building’s internal or external structural components. If the trust engages in property development or sells new dwellings, GST registration may be required and GST must be remitted on the sale price, typically one-eleventh of the contract price.

Commercial Residential Property

Commercial residential premises, such as hotels, motels, boarding houses, and residential parks, are treated differently to ordinary residential premises. Rent from these properties is a taxable supply, not an input-taxed supply. If the family trust owns and operates commercial residential property and the income exceeds the $75,000 threshold, GST registration is required.

Short-Term Holiday Letting

The ATO’s position on short-term accommodation, such as properties listed on holiday rental platforms, is that it may or may not be input-taxed, depending on the circumstances. Continuous residential accommodation (standard long-term tenants) is input-taxed. High-volume short-term holiday letting may be treated as a taxable supply if the property is considered commercial residential premises. If a family trust operates a holiday rental at scale, specialist advice is warranted before assuming the income is input-taxed.

What Happens If Your Trust Is Registered for GST?

If the family trust is registered for GST, either because of other business activities or because it meets the threshold through taxable supplies, here is what that means in practice:

• The trust must lodge Business Activity Statements (BAS) quarterly or monthly
• GST collected on taxable supplies must be remitted to the ATO
• The trust can claim GST credits on expenses related to taxable supplies
• Residential rental income remains input-taxed, no GST is charged to tenants, and no credits can be claimed on rental property costs

Running a trust with both taxable business income and input-taxed rental income requires careful record-keeping to correctly apportion expenses. Many property investors underestimate the administrative complexity this creates, particularly at BAS time.

Should You Voluntarily Register for GST?

Voluntary GST registration is possible even if the trust’s income falls below the $75,000 threshold. However, for a family trust holding only residential rental property, voluntary registration rarely makes sense:

• Residential rent is input-taxed, so registration does not allow the trust to claim GST credits on property expenses
• Registration creates an ongoing BAS lodgement obligation with no corresponding benefit
• There is no GST to collect on residential rent, so the administrative burden outweighs any advantage

The position is different if the trust also engages in taxable business activities. In that case, voluntary registration may allow the trust to claim credits earlier or manage cash flow more effectively. This is worth discussing with a registered tax agent before making the decision.

How This Interacts With Negative Gearing

It is worth clarifying how GST treatment relates to negative gearing. Negative gearing is an income tax concept, it refers to claiming a deduction for a net rental loss (where expenses exceed income) against other assessable income. GST and income tax are separate systems that operate independently.

Because residential rent is input-taxed for GST, the trust cannot claim GST credits on property expenses. However, those same expenses, property management fees, loan interest, repairs, maintenance, and depreciation, are generally deductible for income tax purposes under the ordinary negative gearing rules. The two systems do not affect each other.
