Tax Depreciation: What Property Investors Risk Missing Out On
At MIX Property Group, we’re big believers that successful property investing doesn’t stop at purchase.
While securing the right property is important, it’s what happens after settlement that often makes the biggest difference to long-term performance. One of the most commonly overlooked opportunities we see with investors is tax depreciation — a simple but powerful way to improve cash flow and overall returns.
One thing that often stands out is how much effort goes into getting into a deal… and how little goes into optimising it afterwards.
We obsess over the purchase — the suburb, the price, the growth story, the yield. Then we settle, secure a tenant, and it’s easy to let the property run on autopilot.
Meanwhile, sitting quietly in the background is one of the easiest ways to improve the performance of that asset: tax depreciation.
Not because it’s difficult — but because it’s often misunderstood or simply not front of mind.
At a basic level, tax depreciation is the ATO recognising that your investment property is wearing out over time. The building ages, carpets deteriorate, and appliances don’t last forever. Even though you’re not replacing these items every year, they are still losing value.
The tax system allows you to claim that loss in value as a deduction.
The key benefit? It’s a non-cash deduction. You’re not actually spending the money each year, but you still receive the tax benefit.
That’s where it becomes powerful.
For example, if your depreciation claim is $10,000 in a year and you’re on a 37% marginal tax rate, that’s around $3,700 back in your pocket — without increasing rent or making changes to the property.
When you zoom out, the impact becomes even more significant.
Over five, ten, or fifteen years, these benefits compound. They can improve cash flow, reduce holding costs, and in some cases make a property far more comfortable to retain long-term.
Most investors focus on rent, interest rates, and expenses — but the real performance is what happens after tax.
Two properties may look identical on paper, but once depreciation is factored in, one can perform noticeably better from a cash flow perspective.
What Can You Actually Claim?
There are two main components:
1. The Building (Capital Works)
This typically depreciates at 2.5% per year based on construction cost.
2. Plant & Equipment
This includes items like carpets, blinds, appliances, and air conditioning. These depreciate faster and often drive higher deductions in the early years.
However, an important rule applies. Since 9 May 2017, investors generally cannot claim depreciation on second-hand plant and equipment in residential properties.
This means:
• Established property = existing assets usually not claimable
• New property or newly installed assets = claimable
So the opportunity is still there — it just depends on how and when assets were acquired.
“My Property Is Too Old” — Not Necessarily
A common misconception is that older properties don’t qualify.
In reality, many still do.
Even if the original structure doesn’t apply, renovations, upgrades, or newer components often can. It’s not unusual for older properties to still generate meaningful deductions once properly assessed.
Timing Matters
Depreciation benefits are typically strongest in the earlier years of ownership.
Delaying a depreciation schedule doesn’t mean you lose it entirely, but you may miss out on the timing advantages that help improve early cash flow.
What About Capital Gains Tax?
Depreciation (particularly on the building) can reduce your cost base, which may increase your capital gain when selling.
However, in most cases, you’ve already benefited from improved cash flow over many years. When factoring in the time value of money, investors are generally still in a stronger position overall.
The Bigger Picture
Property investing is often framed around the big decisions — when to buy, when to sell, and where to invest.
But much of the real performance comes from the smaller, often overlooked optimisations.
Tax depreciation is one of those.
It doesn’t change the property or the market — but it can significantly change your outcome.
And if it’s not being done properly, that’s where investors risk missing out.
