Capital Gain on the sale of a rental property

Selling a rental property in Australia can have significant tax implications, particularly concerning Capital Gains Tax (CGT). Understanding your CGT obligations is crucial for property investors to navigate the financial outcomes of such transactions. This guide delves into the essentials of CGT on rental property sales, providing clarity and guidance to property owners.
 

Understanding Capital Gains Tax (CGT). 


CGT is a tax on the profit (capital gain) you make from selling or disposing of an asset, such as real estate, which has increased in value. The key to CGT is determining whether you've made a capital gain or loss upon the sale of your rental property, which largely depends on when the property was acquired.

 

Properties Acquired Before 20 September 1985

If you purchased your rental property before 20 September 1985, you're in luck. Such properties are exempt from CGT, reflecting the tax's introduction date. However, this exemption comes with a caveat. Any major capital improvements made to the property after 19 September 1985 may be subject to CGT if they meet specific criteria, such as constituting more than 5% of the sale proceeds or exceeding the improvement threshold. 


These improvements are considered separate CGT assets, and their cost base is compared to the attributable sale proceeds to calculate the capital gain or loss.


Properties Acquired On or After 20 September 1985

For properties purchased on or after this date, the scenario changes. You may incur a capital gain or loss when you dispose of the property. The difference between the sale price (capital proceeds) and the cost base (essentially, what you've invested in the property) determines whether you've made a gain or loss. A sale price higher than the cost base results in a capital gain, while a sale price lower than the reduced cost base may lead to a capital loss.



Calculating the Cost Base.

The cost base of a property includes various elements. It's important to note that certain deductions and adjustments apply, especially concerning depreciable assets and capital works deductions, which can affect the cost base and, subsequently, the CGT calculation.

  1. Purchase Cost: The total money or property value given to acquire the asset.
  2. Incidental Costs: Expenses related to acquiring, selling, or disposing of the asset, such as stamp duty and legal fees.
  3. Ownership Costs: Ongoing costs like insurance, rates, and land taxes. However, for CGT purposes, the reduced cost base substitutes ownership costs with the balancing adjustment amount related to depreciable assets.
  4. Improvement Costs: Costs incurred to enhance or preserve the property's value or to install or relocate assets.
  5. Title Defense Costs: Legal fees spent defending your property's ownership, except when they've been claimed or are claimable as tax deductions.


 

Exclusions for Certain Costs

Certain costs associated with your property cannot be included in your CGT calculations if:

  1. For All Properties: You have already claimed, or are eligible to claim, a tax deduction for these costs in any tax year. This eligibility remains as long as the option to amend the relevant income tax assessment has not expired.
  2. For Properties Acquired Before 21 August 1991: In addition to the general exclusion criteria, costs associated with assets acquired before 21 August 1991 are specifically excluded, reflecting historical tax legislation nuances.
  3. For Properties Acquired After 31 May 1997: Costs are excluded if you have claimed, or can claim, a tax deduction for them in any income year. This is particularly pertinent to assets acquired post-31 May 1997, aligning with specific tax rulings introduced at that time.


Calculating the Reduced Cost Base
  1. Incorporate All Cost Base Elements With Modifications. Include all original cost base elements but replace the third element (costs of owning the CGT asset) with the balancing adjustment amount. This adjustment is typically related to the sale of depreciable assets within the property, providing a more accurate reflection of your investment's cost.
  2. Exclude Indexation. Avoid applying indexation to the reduced cost base elements. This simplification ensures a straightforward calculation by maintaining current dollar values without adjusting for inflation over time.


Accounting for Capital Works Deductions

If your property was acquired after 13 May 1997, capital works deductions play a significant role in your CGT calculation. Deduct any capital works deductions you have claimed or are entitled to claim. This adjustment is necessary whether you've already claimed these deductions in any income year or if the option to claim them remains open due to an unexpired amendment period for your tax assessment.


Managing Depreciating Assets

Depreciating assets within your property are treated distinctly from the property itself for CGT purposes. When calculating your capital gain or loss, you must exclude the value of depreciating assets at both the time of purchase and sale from the property's cost base and capital proceeds.

A new way to claim work-related expenses is coming for the 2027 tax return — but there is an important catch. From 1 July 2026, eligible taxpayers can claim a standard deduction of up to $1,000 for certain work-related expenses, without having to substantiate each expense individually. Sounds simple enough. But before you assume you can claim $1,000 on top of everything else, there are a few things you need to know. The $1,000 Is the Maximum The new standard deduction is capped at $1,000. It is designed to cover certain common work-related expenses, such as work-related phone and internet, home office expenses, stationery and some travel expenses. You can't claim the $1,000 and then claim those same expenses again separately. If you have actual work-related expenses of more than $1,000, you can continue to claim your actual expenses under the existing rules, provided you meet the requirements and have the records to support them. Do I Still Need to Keep My Receipts? Yes: and this is where it is worth being organised. If you use the standard deduction, you don't need to substantiate the individual expenses covered by it. But if you think your actual work-related expenses could be more than $1,000, keeping your receipts and records throughout the year will allow you to claim your actual expenses instead. There are also some deductions that aren't covered by the standard deduction and can still be claimed separately if you are eligible. It's for Your 2027 Tax Return The new deduction applies from the 2026–27 financial year, so you won't use it for the tax return you are preparing now. It will first apply to your 2027 tax return, lodged from July 2027. Is the $1,000 a $1,000 Tax Refund? No. The $1,000 is a deduction from your taxable income. It doesn't mean you'll receive an extra $1,000 back from the ATO. The value of the deduction will depend on your individual tax circumstances. What Should You Do Now? The best thing you can do is keep track of your work-related expenses throughout the 2026–27 financial year. When it comes time to prepare your 2027 tax return, we can look at your circumstances and determine whether the standard deduction or claiming your actual expenses is likely to give you the better outcome.  At Ascent Accountants, we can help you make sense of the new rules and make sure you're claiming the deductions you're entitled to: without claiming the same expense twice!
