Tax Depreciation When Selling an Investment Property in Brisbane

Depreciation deductions you claimed during ownership have direct consequences at sale time. Here is what investors need to understand before they list.

Most property investors understand that depreciation deductions reduce their taxable income during the years they hold a property. What fewer investors appreciate is how those same deductions interact with their capital gains tax liability when they sell. Understanding the connection before you list can prevent surprises at settlement and help you time the sale more effectively from a tax perspective.

This is not a replacement for qualified tax advice. Depreciation and CGT interact in ways that depend on your personal tax situation, ownership structure, and the specific history of the property. But knowing the basics means you can have a more informed conversation with your accountant well before you sign an agency agreement.

What a depreciation schedule actually records

A depreciation schedule prepared by a quantity surveyor documents two separate categories of deductions. The first is plant and equipment depreciation (division 40), which covers removable assets such as appliances, carpet, hot water systems, and air conditioning units. These items have individual effective lives, and investors claim a portion of their value each year as the assets age. The second is capital works deductions (division 43), which covers the structural elements of the building itself, including walls, roofing, concrete, plumbing fixed to the structure, and built-in fittings. Division 43 deductions are typically claimed at a flat rate of 2.5% per year for residential buildings built after September 1987.

Both categories reduce your taxable income during ownership. The distinction matters at sale time because each category is treated differently for tax purposes when you exit the investment.

Plant and equipment: what happens when you sell

For plant and equipment items, depreciation deductions claimed during ownership do not affect your CGT cost base directly. Instead, when you sell the property, the written-down value of each plant and equipment item is considered a balancing adjustment. If you sell the property for a price that allocates value to those items above their written-down value, you may have a taxable balancing charge. If you sell below written-down value, you may have an allowable deduction.

In practice, residential property contracts rarely separate out the value of individual plant and equipment items. The sale is treated as a lump sum, and your accountant will need to work through the depreciation schedule to determine what, if any, balancing adjustments apply. This is one reason why having an up-to-date depreciation schedule available before sale is useful rather than optional.

It is also worth noting that since the 2017 federal budget changes, investors who purchased second-hand residential properties after 9 May 2017 cannot claim depreciation on existing plant and equipment items. If you bought an established property in Brisbane after that date, your plant and equipment claims may be limited or nil, depending on what was replaced or installed after settlement.

Capital works deductions and your CGT cost base

This is where the interaction becomes most significant for most investors. Every division 43 capital works deduction you have claimed during ownership reduces your CGT cost base by an equivalent amount. If you claimed $30,000 in capital works deductions over a ten-year ownership period, your cost base is $30,000 lower than it would have been without those claims. A lower cost base means a larger capital gain when you sell, which means a larger CGT liability.

This is not a mistake or a penalty. The logic is that you have already received the tax benefit of those deductions as income offsets during the years you held the property. Reducing your cost base at sale simply ensures you do not receive a double benefit for the same underlying expenditure. The tax benefit was real during ownership. The CGT implication at sale is the corresponding cost.

For investors who have held Brisbane investment properties for ten years or more and claimed substantial capital works deductions, this can represent a meaningful increase in their taxable capital gain. Your accountant needs your full depreciation history, not just the current year schedule, to calculate this accurately.

Should you get a depreciation report before selling?

If you already have an up-to-date depreciation schedule, you have what you need. If you have been relying on your property manager's records or claiming depreciation without a formal quantity surveyor report, getting one before you sell is worth considering, primarily to ensure your cost base has been calculated correctly throughout the ownership period.

A depreciation report prepared retrospectively can help you identify any deductions you missed claiming, which can be corrected through an amended return with the ATO, subject to time limits. It also gives your accountant a clear reconciliation of what has been claimed and what the corresponding cost base adjustments should be. For properties where significant renovations or capital improvements were made during ownership, the record-keeping around those costs is particularly important.

From a buyer's perspective, a current depreciation schedule can also be a useful marketing document. Buyers who are purchasing for investment can see at a glance what deductions remain available to them going forward. For newer properties or recently renovated ones, this is a genuine selling point.

The difference between your property manager's records and a tax accountant's advice

Property managers keep records of rental income, maintenance costs, and property management fees, which are the inputs for your annual tax return. They are not, and should not be expected to be, the source of truth for your depreciation claims or your cost base calculations. These are accounting and tax functions that sit with your accountant or tax agent.

If you have been filing tax returns with depreciation claims that were prepared by your accountant using a quantity surveyor report, your cost base adjustments are likely to be correct. If you have been estimating depreciation or relying on generic schedules without a site-specific quantity surveyor report, your cost base may be inaccurate. This is a risk worth resolving before you exchange contracts.

The best time to have this conversation with your accountant is before you engage an agent, not after you receive an offer. Understanding your likely CGT liability at the expected sale price helps you make a clearer decision about timing, pricing, and whether a 12-month CGT discount applies to your situation.

Timing considerations for Brisbane investors

If you have owned the property for less than twelve months, you will not qualify for the 50% CGT discount available to individual investors who have held an asset for more than a year. This is a significant factor for investors who purchased during a period of strong growth and are now considering selling. The difference between selling at month eleven and month thirteen can be substantial.

For investors approaching the end of a financial year, timing settlement can also affect which year the capital gain falls into. If the gain is large and your other income for the year is high, deferring settlement by a few weeks to push the gain into the following financial year can reduce the marginal rate at which it is taxed. This kind of timing decision requires specific advice based on your actual income position.

The Brisbane inner east market generally runs to its own calendar. Strong buyer demand in the autumn and spring campaign periods means a well-prepared property can sell quickly. If you need settlement to fall in a specific financial year, tell your agent early so the campaign can be structured accordingly.
