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.

If your business provides a car to an employee (or you’re the business owner/employee using it), there’s a good chance the Fringe Benefits Tax (FBT) rules apply. A car fringe benefit arises when a car owned or leased by an employer is made available for the private use of the business owner, an employee or their associate (such as a family member). “Private use” doesn’t just mean weekend road trips — it can include everyday commuting and even cases where the car is parked at an employee’s home, making it available for personal trips. Understanding how FBT is calculated and what records to keep is essential for compliance — and for avoiding paying more tax than necessary. What counts as a “car” for FBT purposes? The FBT law defines a car as a motor vehicle (except a motorcycle or similar) designed to carry less than one tonne and fewer than nine passengers. From 1 July 2022, some zero or low-emission vehicles are exempt from FBT, provided they meet certain criteria — for example, they must be first held and used after 1 July 2022 and must not have attracted Luxury Car Tax. Electric vehicle running costs, such as charging, are also exempt when the vehicle itself qualifies. Two main methods for calculating FBT on cars There are two ways to calculate the taxable value of a car fringe benefit. 1. Statutory formula method This method applies a flat 20% statutory rate to the base value of the car, adjusted for the number of days in the FBT year the car was available for private use. The formula is: (A × B × C ÷ D) − E A = Base value of the car (cost price plus GST and certain accessories, less registration, stamp duty and eligible reductions) B = Statutory fraction (generally 20%) C = Days available for private use D = Total days in FBT year (365) E = Employee contributions If the car has been owned for at least four full FBT years, the base value can be reduced by one-third. 2. Operating cost method This method calculates the taxable value by applying the private use percentage to the total operating costs of the car (actual and deemed costs). The formula is: Taxable value = [Operating costs × (100% − Business use %)] − Employee contributions Operating costs include: Fuel, oil, repairs, maintenance, registration and insurance Lease costs (for leased cars) Deemed depreciation (25% diminishing value) and deemed interest for owned cars Certain costs, such as tolls, car parking and insurance-funded repairs, are excluded. The business use percentage is determined by odometer readings, logbook records, and a reasonable estimate based on usage patterns. The three-month logbook requirement (operating cost method only). If you use the operating cost method, you must keep a logbook for at least 12 continuous weeks (roughly three months) to record: The date of each trip Odometer readings at the start and end Total kilometres travelled Whether the trip was for business or private purposes The purpose of each business trip This logbook is generally valid for five years, but you must start a new one if usage patterns change significantly (e.g., a role change, relocation or different duties). You also need to record odometer readings at the start and end of each FBT year. Why record-keeping matters. Keeping accurate records can support a higher business use percentage (and therefore a lower FBT bill). They also ensure you claim only legitimate business kilometres and help you provide evidence if the ATO reviews your FBT calculation. Finally, your records help you decide which calculation method (statutory or operating cost) is more tax-effective. Key takeaways for businesses and employees. If a car is available for private use, FBT may apply — even if the car isn’t driven often for personal trips. Electric cars may be FBT-exempt if they meet eligibility criteria, but you may still need to calculate their taxable value for reporting purposes. The operating cost method often works better if business use is high — but only if you have a compliant logbook. Keep odometer readings, expense records and a valid logbook to support your claims. Need help with your FBT obligations? Get it at Ascent Accountants. We guide business owners through every step of FBT compliance — from choosing the right valuation method to maintaining the right records for ATO peace of mind. If you provide cars to employees or use a company vehicle yourself, now is the time to review your FBT position before the next FBT year rolls over. Let’s talk .
