CGT on Queensland Property Sales: What Real Estate Agents Should Be Able to Explain

Your vendor has just asked whether they’ll pay tax on their sale. They own an investment unit on the Sunshine Coast, purchased eight years ago and rented out the entire time. The price has moved considerably. You know this is a question for their accountant — but you also know that walking into that conversation completely blind does not inspire confidence. Understanding how capital gains tax works on Queensland property sales, well enough to frame the issue clearly and direct clients appropriately, is part of doing your job properly.

This is not tax advice. It is factual, legislative context that every working Queensland real estate agent should carry.

The Fundamentals: What CGT Actually Is

Capital gains tax operates by treating net capital gains as taxable income in the tax year in which an asset is sold or otherwise disposed of. It is not a separate tax with its own return — it is folded into the vendor’s income tax assessment for the year in which the CGT event occurs.

The critical point for agents to understand is when the CGT event occurs. If there is a contract to sell the asset, the CGT event happens on the date of the contract, not when settlement occurs. Property sales usually work this way. This matters practically: a vendor who signs a contract on 28 June and settles on 15 August is reporting that gain in the tax year ending 30 June — not the following year. It also has direct implications for the 12-month holding period discussed below.

The CGT law is expressed in terms of 52 CGT events, each specifying results such as gain, loss, or what cost base adjustments are to be made. The most common event is A1, the disposal of an asset. On disposal, a capital gain arises if the proceeds are greater than the cost base; a capital loss arises if they are less than the reduced cost base.

One further baseline: any asset acquired before 20 September 1985 is a pre-CGT asset and generally attracts no CGT liability at all. Estates selling older properties occasionally involve pre-CGT assets — something worth flagging to vendors so they understand why their accountant may be asking about the original acquisition date.

Understanding the Cost Base: Where the Calculation Starts

The cost base is the foundation of every CGT calculation. The cost base of an asset is the total amount it has cost you to acquire, own, and dispose of that asset. When you sell a capital asset, the ATO calculates your capital gain by subtracting the cost base from the capital proceeds. The higher your cost base, the lower your capital gain, and the less tax you pay.

The rules are set out in Division 110 of the Income Tax Assessment Act 1997 (ITAA 1997). The ATO recognises five separate elements that make up the cost base of an asset. For property, these typically work as follows:

• Element 1 — the purchase price itself, plus stamp duty, legal fees, and other costs directly associated with acquiring the asset
• Element 2 — incidental costs of acquisition and disposal, including agent commissions, conveyancing fees, and valuation costs
• Element 3 — costs of owning the asset, including interest on money borrowed to acquire the asset, and costs of maintaining, repairing, or insuring it — but only where those costs were not already claimed as a tax deduction
• Element 4 — capital expenditure the purpose or expected effect of which is to increase or preserve the asset’s value
• Element 5 — capital expenditure to preserve or defend title or rights to the asset

For investment property owners, the interaction between rental deductions and Element 3 of the cost base is a common source of confusion. Costs that have already been deducted against rental income cannot be added to the cost base — you do not get to count the same dollar twice.

Agents who regularly list investment properties should understand this at a conceptual level. When a long-term investor asks “won’t my renovations reduce the tax?”, the correct answer is: capital improvements that were not deductible may increase the cost base, but a client should confirm the treatment with their accountant based on their specific records. Depreciation claims under Division 40 of the ITAA 1997 further complicate the cost base picture, as deductions already taken reduce the effective cost base on disposal.

Any asset acquired before 20 September 1985 is a pre-CGT asset and is generally exempt from capital gains tax entirely. For everything else, the starting point is always: what did this property cost, in the broadest legitimate sense, and what are the proceeds?

The 50% CGT Discount: The Rule That Changes Everything

Most residential and investment property vendors selling after more than a year of ownership are entitled to a significant concession. If an asset is held for at least one year, any gain is first discounted by 50% for individual taxpayers, or by 33.3% for superannuation funds.

The discount is provided under Division 115 of the ITAA 1997. To qualify, you must have held the asset for at least 12 months before the CGT event — usually the date of contract for sale, not settlement. The 12 months is calculated from the day after acquisition to the day of disposal.

The discount is applied after the cost base has been fully calculated and after any capital losses have been applied to reduce the gain. You do not apply the discount to the cost base itself; it reduces the net capital gain that is included in your assessable income.

The practical effect is substantial. Suppose a vendor purchases an investment property for $500,000 (including stamp duty, legal fees, and other cost base elements) and sells it three years later for $700,000. The gross capital gain is $200,000. If they have $20,000 in capital losses from other investments, the net gain is $180,000. Applying the 50% individual discount reduces the taxable amount to $90,000, which is then added to other assessable income and taxed at the marginal rate.

Ownership structure matters significantly here. Companies are not eligible for the CGT discount. A company that makes a capital gain includes the full amount in its assessable income and pays tax at the company rate — currently 25% for base rate entities with aggregated turnover under $50 million, or 30% for other companies. Vendors who hold property through a company do not benefit from the discount at the entity level. Trusts are a different matter: trusts are entitled to a 50% discount, which is generally applied before the net capital gain is distributed to beneficiaries, but the way the discount interacts with trust distributions requires careful planning, and the ATO has specific rules — including section 115-215 of the ITAA 1997 — governing how trustees and beneficiaries apply the discount.

For agents, the takeaway is simple: before assuming a vendor benefits from the 50% discount, confirm how the property is held. A property owned in a company structure requires an accountant’s involvement before the vendor can form any view on their net CGT exposure.

The Main Residence Exemption: Full, Partial, and Gone

The most commonly misunderstood area of CGT for Queensland property agents is the main residence exemption. Vendors regularly believe they are fully exempt when they are not, and occasionally believe they have lost the exemption when it is partially intact.

The main residence exemption applies if you are an Australian resident and the dwelling has been the home of you, your partner, and other dependants for the whole period you owned it, and has not been used to produce income — that is, you have not run a business from it, rented it out, or flipped it. If you meet these conditions, you do not pay tax on any capital gain when you sell your home.

The exemption generally covers the house itself plus a maximum of two hectares of the land it sits on. This land must be used for private, domestic purposes. A rural residential property on five acres, for example, will only receive a partial exemption on the excess land — a scenario agents working in the Scenic Rim, Sunshine Coast hinterland, or regional Queensland need to understand.

Partial Exemptions: The Pro-Rata Calculation

If a vendor does not meet all the conditions for a full exemption, they may still be entitled to a partial exemption. The full exemption is proportionately reduced by reference to the period for which the dwelling was not the taxpayer’s main residence. The taxable capital gain is then calculated as:

Total capital gain × (Non-main residence days ÷ Total ownership days)

The CGT discount may then be applied to further reduce the remaining gain.

This formula catches several very common Queensland scenarios:

• A vendor who purchased an investment property, rented it out for three years, then moved in and eventually sold
• A vendor who lived in the property, then moved away and rented it out beyond the six-year absence period
• A vendor who ran a business from a dedicated portion of the home

The Six-Year Absence Rule

The six-year rule allows Australian property owners to continue treating a former main residence as exempt from CGT for up to six years after moving out, if the property is used to produce income. If the property is not rented or otherwise income-producing, the owner may continue treating it as their main residence indefinitely, without any six-year limit.

The rule is not automatic. It is a choice the vendor makes — they have to continue treating the property as their main residence for tax purposes, even while they are not living there and tenants are. The critical catch: Australian tax law usually allows only one property to be treated as the main residence at any given time. A vendor who moves out, rents their existing home, and buys a new property they also treat as their main residence has a problem — they cannot claim both.

Moving back in and re-establishing the property as the main residence resets the six-year absence period for future use. Vendors who have done this — moved out, rented, moved back, rented again — need careful accountant input to work through the period-by-period calculation.

When the Exemption Disappears: Non-Resident Sellers

This is the area where agents working with international sellers or Australians living abroad need to be particularly alert. If you are a foreign resident when a CGT event happens to your residential property in Australia, you are generally not entitled to claim the main residence exemption.

As of 1 July 2020, a non-resident of Australia for tax purposes cannot claim the main residence exemption even if the requirements of the six-year rule are met. The test is the vendor’s residency status at the time of the CGT event — not where they lived for most of their ownership period.

Foreign residents are eligible for the main residence exemption within six years of becoming a non-resident if a certain life event occurs. Life events include death of a spouse or child under 18, a terminal medical condition, or relationship breakdown. Outside of those narrow circumstances, a non-resident vendor selling their former Australian home faces full CGT exposure on any gain — including the period when they were an Australian resident. This is a significant outcome that vendors are often unprepared for, and it warrants immediate direction to an accountant the moment you understand your vendor is living overseas.

FRCGW: What Agents Need to Know at the Coalface

Foreign Resident Capital Gains Withholding — FRCGW — is an area where real estate agents have a direct, practical role. Understanding it prevents settlement delays and protects vendors from unnecessary surprises.

The FRCGW scheme exists in Subdivision 14D of Schedule 1 to the Taxation Administration Act 1953 (Cth). Its purpose is straightforward: the measures exist so the ATO can collect tax from foreign residents who might otherwise leave Australia without paying CGT.

The Current Rules (Contracts from 1 January 2025)

The change was announced through the 2023–24 Mid-Year Economic and Fiscal Outlook process and legislated via the Treasury Laws Amendment (2024 Tax and Other Measures No. 1) Act 2024. The law lifted the rate from 12.5% to 15% and removed the $750,000 threshold so more transactions are covered. These amendments took effect for contracts entered on or after 1 January 2025.

The practical result: non-residents must remit 15% of the sale price or lease premium to the ATO when selling property in Australia, regardless of the property’s value. Purchasers must pay any amount they withhold to the ATO at or before settlement.

For contracts signed prior to 1 January 2025, the previous rules apply: non-residents were subject to a 12.5% withholding rate, provided the property was valued at $750,000 or more.

The Clearance Certificate: Why Every Australian Vendor Needs One

This is the critical operational point for agents. FRCGW must be withheld on all real property sales unless the vendor is an Australian resident for tax purposes. All Australian residents selling or disposing of Australian real property must have a clearance certificate and give it to the purchaser at or before settlement. Without a clearance certificate, the purchaser must withhold up to 15% of the sale price.

Applications are free and typically processed within a few days, though some may take up to 28 days. Each vendor listed on the property title must apply individually. A property with two registered owners requires two separate clearance certificate applications. The clearance certificate is valid for 12 months from its date of issue.

In Queensland, the Contract for Houses and Residential Land provides that the buyer is authorised to pay the FRCGW to the ATO if the sale is not an excluded transaction and the seller has not given the buyer a clearance certificate or variation on or before settlement. The buyer must lodge the FRCGW Purchaser Notification Form with the ATO on or before settlement.

The risk to an Australian vendor who overlooks this is real. If they do not have their clearance certificates, 15% of the sale price would have to be withheld by the purchaser as FRCGW and paid to the ATO. They would then have to wait until their tax return is lodged and processed for a refund, which could delay purchasing a new residence.

For Genuine Non-Resident Vendors

Where the vendor is actually a foreign resident for tax purposes, FRCGW is not a final tax. Any differences between the amount withheld and the actual tax liability are resolved when the vendor lodges their tax return. A non-resident vendor whose actual CGT liability is less than 15% of the sale price can apply to the ATO for a variation to reduce the withholding rate before settlement. This is an important option for vendors — particularly those with high cost bases or other offsets — and requires early accountant involvement to execute in time.

Importantly, the 50% capital gains tax discount for foreign and temporary resident individuals on taxable Australian real property is no longer available for capital gains accrued after 7:30 pm AEST on 8 May 2012. Non-resident vendors therefore face the full, undiscounted gain being subject to Australian tax — another reason their tax exposure can be significantly higher than an equivalent Australian resident vendor.

Investment Property vs Main Residence: The Scenarios Agents Encounter

The scenarios that generate the most confusion in Queensland transactions are rarely clear-cut. Here are the most common situations, and what they mean practically.

The long-term investor selling an established investment property. The vendor has owned a rental property for ten years, never lived in it. CGT applies to the full gain. The cost base includes the purchase price, stamp duty, legal fees, agent commissions on acquisition and sale, and any capital improvements not previously deducted. The 50% discount applies because the holding period exceeds 12 months. The vendor’s accountant calculates the gain, applies any available capital losses, applies the discount, and includes the resulting figure in assessable income.

The vendor who lived in the property, then rented it, then sold. This is the partial exemption scenario. The period during which the property was the main residence is exempt; the period during which it produced rental income is assessable, subject to the six-year rule if applicable. The 50% discount can still reduce the assessable portion. Accurate records of dates — move-in, move-out, commencement and end of tenancy — are essential and should be in the vendor’s hands before they engage their accountant.

The vendor renting out a room or section of their home. If a vendor rented out part of their home — a spare room through a short-stay platform, for example — while still living there, that portion of the property is no longer fully eligible for the main residence exemption. The proportion of the home used for income-producing purposes generates a partial CGT liability on sale. This is a common scenario in Queensland’s coastal markets where short-term accommodation has been widespread.

The vendor who moved out and bought a new home. If a vendor buys a new home while renting out the old one, they need to decide which property they are treating as their main residence for each income year. Getting the election wrong can cost the exemption on one or both properties. This is a question for their accountant before they list, not after they have exchanged contracts.

The overseas vendor. Confirm residency status for Australian tax purposes as early as possible. FRCGW will apply. The main residence exemption is almost certainly unavailable. The 50% discount may be partially or fully unavailable. Direction to an accountant or tax adviser familiar with non-resident property sales is essential before listing.

What This Means for Queensland Agents

Your role is not to calculate a vendor’s CGT liability. It is to understand the framework well enough to identify issues early, ask the right questions, and direct clients to the right professionals before a problem surfaces at settlement.

Start every listing conversation involving an investment property, a property with mixed use history, or a vendor living overseas with a direct question: have you spoken to your accountant about the CGT position? If they have not, encourage them to do so before you list. A vendor blindsided by a CGT liability after exchange — particularly a non-resident vendor facing a 15% FRCGW withholding — will associate that outcome with their agent, regardless of where the fault lies.

Build the clearance certificate into your standard pre-settlement checklist for every transaction, not just those where you suspect a foreign vendor. The residency test for individuals for taxation purposes is different to that for social security and immigration purposes. A vendor who has been living overseas for two years on a working visa may not identify as a non-resident — but may be one for Australian tax purposes. The clearance certificate resolves the question definitively.

For investment properties, advise vendors early that good record-keeping is the foundation of a defensible CGT calculation. The ATO expects complete records of everything related to the property, from the date of purchase through to the date of sale. For the six-year rule specifically, that means documenting when they moved out, when tenancy began, rental income received, all rental-related expenses, any capital improvements made, and the dates they moved back in if applicable. Vendors without these records face higher accountant fees and less certainty about their final tax position.

Know the key trigger dates. The CGT event happens at contract, not settlement. The 12-month holding period runs from day after acquisition contract to day of disposal contract. FRCGW must be resolved at or before settlement. Clearance certificates are valid for 12 months. A non-resident vendor’s variation application to reduce withholding below 15% takes time — it cannot be lodged the day before settlement.

Finally, stay current. The FRCGW regime changed materially on 1 January 2025. The political conversation around the 50% CGT discount continues. Tax rules affecting property transactions are not static, and the agents who serve their clients best are the ones who notice when the landscape shifts.
