What Is CGT in Queensland Real Estate? Definition and Agent Guide
Your vendor has just agreed a price. The calls are coming in. Then the seller asks: “What’s this going to cost me in tax?” Capital gains tax (CGT) in Queensland real estate is the federal tax payable on the profit a taxpayer makes from disposing of a property — calculated as the difference between the property’s sale proceeds and its cost base, then added to the vendor’s assessable income for that financial year. Understanding how CGT works, when exemptions apply, and how the rules affect your clients is not optional professional knowledge for a Queensland agent. It shapes pricing conversations, negotiation timing, and how confidently you can advise vendors to see their accountant before they sign anything.
How CGT Works in Queensland Real Estate
In Queensland, CGT follows federal rules set by the Australian Taxation Office (ATO), not state law. It is not a standalone tax. Australia does not have a separate CGT rate — capital gains are added to a taxpayer’s assessable income for the year and taxed at their marginal income tax rate. The practical implication is that the amount of CGT a vendor owes depends entirely on their total taxable income in the year of sale — a vendor who earns $90,000 in salary plus a $150,000 capital gain faces a very different outcome than a retired investor with minimal other income.
The profit subject to CGT is calculated by subtracting the property’s cost base from the capital proceeds. The net capital gain is the sale price minus the cost base, which includes the purchase price, stamp duty, legal fees, selling costs and eligible expenses like renovations or improvements. The rules for what constitutes the cost base are set out in Division 110 of the Income Tax Assessment Act 1997 (ITAA 1997). A correctly calculated cost base — one that captures every legitimate acquisition and ownership cost — can substantially reduce a vendor’s exposure. Agents who understand this can have genuinely useful conversations with clients about record-keeping long before a sale is on the horizon.
The CGT event — the moment the gain is crystallised for tax purposes — is a point that trips up many vendors. If there is a contract to sell the asset, the CGT event happens on the date of the contract, not when you settle. Property sales usually work this way. The capital gain for the property happens on the date of the sale contract, not the date of settlement. For example, if contracts are exchanged on 4 June 2025 and settlement happens on 6 July 2025, the vendor must report the capital gain in the tax return for the financial year ending 30 June 2025. This is a critical planning point for vendors who exchange close to 30 June.
The 50% CGT Discount
The most significant CGT concession available to Queensland property investors is the 50% discount under Division 115 of the ITAA 1997. There is a CGT discount of 50% for Australian resident individuals who own an asset for 12 months or more. This means you pay tax on only half the net capital gain on that asset. Individuals (including sole traders) are entitled to a 50% discount, meaning only half of the net capital gain is included in their assessable income and taxed at their marginal tax rate.
The asset must have been owned for at least 12 months before the CGT event occurs. The 12-month period is calculated from the date of acquisition — usually the contract date, not the settlement date — to the date of the CGT event, which is usually the contract date for the sale. Companies do not receive this 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. This distinction matters when you are working with investors who hold property in corporate structures.
Capital losses interact with the discount in a specific sequence that affects the final outcome. If a vendor has any capital losses from other assets, they must subtract these from their capital gains before applying the discount. If they are entitled to the discount for an asset, they reduce the remaining capital gain by 50% and report this amount in their income tax return. Losses carried forward from prior years are applied first, reducing the base before the 50% discount halves it — maximising the tax benefit in most circumstances.
The Main Residence Exemption
The most complete CGT shelter available in Australian property is the main residence exemption. Your main residence is exempt from CGT 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 have owned it, and it hasn’t 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 don’t pay tax on any capital gain when you sell your home and you ignore any capital loss.
To be your main residence, your property must have a dwelling on it and you must have lived in it. You’re not entitled to the exemption for a vacant block. The land covered by the exemption is capped: your home is fully exempt from CGT if it was your main residence for the entire ownership period, was not used to produce income, and the land is under 2 hectares.
Where a vendor has rented out their former home before selling, a partial or full exemption may still apply under the six-year absence rule. For CGT purposes, you can continue treating a property as your main residence for up to 6 years if you used it to produce income, such as rent — sometimes called the ‘6-year rule’ — or indefinitely if you didn’t use it to produce income. This six-year absence rule operates under section 118-145 of the ITAA 1997 and can eliminate CGT on properties that appreciate significantly while rented. The clock resets each time the owner moves back in, meaning the exemption can be preserved across multiple periods of absence. The owner cannot nominate another property as their main residence during the same period — they can only have one main residence at a time.
Why CGT Matters for Queensland Agents
CGT is not the vendor’s accountant’s problem alone. It affects agent behaviour, negotiation leverage, and how a vendor frames their acceptable sale price. A seller who faces a substantial CGT bill may need a higher net figure to achieve the same financial outcome as a seller who is fully exempt. When you understand that dynamic, you can have more substantive conversations about realistic pricing rather than talking at cross-purposes.
Timing is where agents add the most practical value in a CGT conversation. A vendor who exchanges contracts just before 30 June crystallises the CGT event — and the tax bill — in that financial year. A vendor who waits until July moves the liability into the following year, potentially at a lower marginal rate if circumstances change. Equally, a vendor who has held a property for eleven months has a powerful reason to wait another month before exchanging, given the 50% discount only applies once the 12-month holding period is met. Raising these points — without giving tax advice — and directing the vendor to their accountant is exactly what a thorough, client-focused agent does.
For investment property sales, CGT exposure affects the relationship between the vendor’s asking price and their actual financial outcome more directly than any other single tax factor. A Queensland investor selling a Sunshine Coast unit they purchased for $500,000 and held for eight years may show a paper gain of $300,000. After applying eligible cost base additions and the 50% discount, their taxable gain may be significantly less — but still substantial depending on their income. Agents who help clients understand the difference between gross sale proceeds and net post-tax outcome build the kind of trust that generates referrals and repeat business.
Queensland’s interstate and international investor base adds another layer of complexity. Southeast Queensland, in particular, has attracted significant interstate buyers over the past several years. When those investors later sell, their CGT calculation applies under federal law regardless of which state they reside in — but the mechanics of the transaction, including contract timing and settlement process, are governed by Queensland procedures. Agents who understand both layers are well positioned to service this cohort effectively.
CGT Exemptions, Special Scenarios, and Foreign Vendor Rules
Inherited Property
CGT applies when you dispose of a CGT asset that you inherited, including properties and shares. However, the rules on deceased estates are nuanced. Under section 118-195 of the ITAA 1997, a full exemption can apply on the sale of a dwelling inherited from a deceased individual if the property was the deceased’s main residence just before their death and was not being used to produce income at that time, and either the property is sold within 2 years of the date of death (the Commissioner can extend this period), or the property has been the main residence of the deceased’s spouse, someone granted a right to occupy under the will, or the individual beneficiary who is selling the property from the date of death until the property is sold.
Queensland agents dealing with deceased estate sales should be aware that the two-year window runs from the date of death, not the date of probate or appointment of the estate’s representative. Beneficiaries who are slow to move on a deceased estate sale can inadvertently step outside the exemption period, exposing themselves to a CGT liability on a property they may have assumed was fully exempt.
Granny Flat Arrangements
From 1 July 2021, no CGT event arises to eligible individuals on certain granny flat arrangements if the arrangement satisfies the requirements of the provisions. A granny flat arrangement is a written agreement that gives an eligible person the right to occupy a property for life. The CGT exemption applies to the creation, variation or termination of a granny flat arrangement. This is worth noting in Queensland’s growing retirement-downsizer market, where dual-living configurations and granny flat arrangements are increasingly common.
Capital Losses
Capital losses can be offset against capital gains. Net capital losses in a tax year cannot be offset against normal income, but may be carried forward indefinitely. A vendor who holds both an investment property and a share portfolio that has declined in value may be able to offset property gains against share losses, reducing their net CGT liability. This is a legitimate strategy but one that requires careful coordination between asset classes — and professional tax advice.
Foreign Residents and CGT Withholding
This is the area where Queensland agents face the most operationally significant CGT obligation. Since 1 January 2025, the foreign resident capital gains withholding (FRCGW) regime has been significantly tightened. On and after 1 January 2025, a rate of 15% applies to the value of all property. As of 1 January 2025, FRCGW applies to every property transaction with no minimum threshold. The previous regime — which applied only to properties valued at $750,000 or more, at a 12.5% rate — has been replaced by a universal obligation.
The mechanism works as follows: FRCGW must be applied on all real property sales, unless the vendor is an Australian resident for tax purposes with a valid clearance certificate issued by the ATO at or before settlement, or a foreign resident with a variation notice specifying a reduced rate. The buyer withholds 15% of the gross sale price — not the gain, the full price — and the withheld amount is remitted directly to the ATO at settlement. This withholding is not an additional tax — it is credited against the CGT due. If the withheld amount exceeds the CGT liability, the excess can be refunded after the vendor lodges their Australian tax return.
Under the REIQ Contract for Houses and Residential Land, 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 (clause 2.5(3)).
Foreign residents cannot access the main residence exemption in most circumstances. If you are a foreign resident when a CGT event happens to your residential property in Australia — for example, you sell it — you generally aren’t entitled to claim the main residence exemption. For the 2025–2026 financial year, the applicable CGT discount for foreign residents on Australian real property is 0% — the 50% general discount available to Australian resident individuals does not apply to foreign residents for gains accruing on or after 8 May 2012.
The residency question is less straightforward than it appears. A vendor can hold an Australian passport and still be a foreign resident for tax purposes if they live and work overseas. The ATO cares about where you live, not what’s on your passport. Australian-born vendors who have relocated overseas — a common situation across the Queensland property market — may be caught by the withholding rules even if they consider themselves Australian. Agents should raise the clearance certificate question early in every listing process. The certificate is free and valid for 12 months from the issue date.
What Queensland Agents Need to Know About CGT
The agent’s role in CGT is clearly bounded: raise the right questions, understand enough to have an informed conversation, refer to the right professionals, and ensure that nothing about the timing or preparation of the transaction inadvertently creates a problem for the vendor. This is distinct from giving tax advice, which is the domain of registered tax agents and accountants.
In practical terms, this means building several habits into every vendor engagement. When taking a listing, ask whether the property has been the vendor’s principal place of residence for the entire ownership period. Ask whether it has been rented at any point. Ask whether the vendor is an Australian resident for tax purposes. These questions are not tax advice — they are the kind of due diligence that allows you to flag potential issues and direct the vendor to seek professional guidance before contracts are prepared.
The ATO clearance certificate is now a standard pre-settlement document for every Queensland property transaction, not just high-value sales. The certificate tells the buyer that the seller is an Australian tax resident, so they don’t need to hold back part of the sale price at settlement. In 2025, the rules around buyer withholding became stricter — the rate increased to 15% and the old $750,000 threshold was removed for contracts entered on or after 1 January 2025. That means if a vendor doesn’t provide a valid clearance certificate by settlement, the buyer must withhold 15% of the sale price and pay it to the ATO, even on lower-priced properties. Agents who do not build clearance certificate awareness into their vendor preparation workflow will find it becoming a settlement-day emergency.
Each person on title needs their own clearance certificate. If a vendor and their spouse both own the property, they both need one. If one gets the certificate and the other doesn’t, withholding can still apply to the co-owner who doesn’t have one. This detail frequently catches joint-ownership vendors off guard at settlement. Addressing it weeks in advance is basic professional practice.
On the contract itself, contract date versus settlement date is not an academic distinction. A vendor who exchanges in late June is crystallising a tax event in the current financial year. If that same vendor has other income already pushing them into a high marginal bracket, exchanging in July instead could make a material difference to their net outcome. CGT is calculated from the date of the contract, not the date of settlement — some vendors assume that a sale before 30 June that settles after 30 June pushes the CGT into the following year, which is incorrect. Clarifying this once can prevent a vendor from making a costly assumption.
Queensland agents also operate with a professional privilege that carries responsibility. Agents operating in Queensland are in a unique position — unlike most other states, Queensland law allows licensed real estate agents to prepare contracts for the sale of property. This is a significant professional privilege and with it comes the responsibility to stay informed and act in the best interests of clients. When the contract schedule includes tax-adjacent options — such as how GST is to be treated, or how land tax adjustments are to be applied at settlement — the agent’s responsibility is to obtain clear instructions from the vendor, not to advise them on which option is appropriate. Agents must not provide any advice about which option is most suitable. If the client is unsure, they should be directed to seek advice from their solicitor or accountant. The same principle applies to CGT positions.
For agents working with investors considering their selling timeline, the interaction between CGT and holding period is worth flagging early. A property approaching 12 months of ownership sits in a zone where the 50% discount does not yet apply. Exchanging contracts before the 12-month mark is met can cost a vendor as much as the discount would have saved them. Identifying this scenario and raising it with the vendor — then directing them to their accountant for confirmation — is the kind of value-added service that distinguishes a skilled agent from a transaction processor.
What This Means for Queensland Agents
CGT is a federal tax administered by the ATO, calculated on the profit from disposing of a property, and added to the vendor’s assessable income for the year. In Queensland real estate practice, it affects every investment property sale, most vacant land transactions, and any residential sale where the property has not been the vendor’s continuous principal place of residence. The main residence exemption, the 50% discount for assets held over 12 months under Division 115 of the ITAA 1997, and the six-year absence rule under section 118-145 are the three most commonly relevant provisions in residential practice.
Your operational checklist on every listing should include: confirm whether the vendor is an Australian resident for tax purposes and have they applied for an ATO clearance certificate; establish whether the property has ever been used to produce income; determine whether the 12-month holding period has been met before exchange; and confirm who holds an interest in title so that clearance certificates are obtained for every vendor.
The one thing a Queensland agent should never do is attempt to advise a vendor on their actual CGT position. The rules are complex, circumstances-specific, and subject to professional penalties if an unlicensed person provides tax advice. The agent’s role is to know enough to ask the right questions, recognise when a CGT issue is in play, and refer the vendor to a qualified tax professional early enough that planning remains possible.
Records must be kept for at least five years after the CGT event is reported. Vendors who have owned properties for decades and lack documentation of original purchase costs, capital improvements, and holding expenses face an unnecessary and often avoidable disadvantage at the time of sale. Encouraging your investment property vendors to maintain thorough records is not tax advice — it is sound practical guidance that will be remembered long after the sale is complete.
