Maintenance vs Depreciation: Why Ignoring Your Rental Is a Tax and Asset Mistake

TL;DR
Spending money on your rental isn't just a cost, it's how you protect the asset and, in the case of repairs and maintenance, claim deductions that reduce your tax. Understanding the difference between deductible repairs and capital improvements, and what can and can't be depreciated, is core to running a rental properly. This post clears up the confusion. Confirm current depreciation rules with your accountant, as they've changed.
Plenty of investors treat maintenance as a grudge cost to minimise. That's a double mistake.
Underspending on a rental degrades the asset, which costs you far more in value and vacancy than the maintenance ever would. And it misunderstands the tax treatment, because genuine repairs and maintenance are deductible, reducing your tax bill. Ignoring your rental is both an asset mistake and a tax mistake.
Repairs and Maintenance vs Capital Improvements
This distinction drives the tax treatment, and it's where people get confused.
Repairs and maintenance restore the property to its existing condition. Fixing a leak, repainting, replacing a broken appliance with a similar one, servicing the heat pump. These are generally deductible in the year you incur them, reducing your taxable rental income.
Capital improvements make the property better than it was, or add something new. Adding a deck, renovating a kitchen to a higher standard, extending the dwelling. These aren't immediately deductible, they're capital, and they're treated differently.
The line between them isn't always obvious, and it's worth getting right because the tax treatment differs significantly. A like-for-like replacement is usually a repair. An upgrade is usually capital. When in doubt, ask your accountant before the work, not after.
The Depreciation Picture
Depreciation is where the rules have changed and confusion is common.
Depreciation on residential buildings has been set at 0% for years, you can't depreciate the building itself. This is an area that has shifted with policy, so it's worth confirming the current position, but the building structure has not been depreciable for residential rentals.
Chattels, the separate, identifiable items like carpets, curtains, appliances, and some fit-out, can generally still be depreciated over their useful life. This is a genuine, often underused deduction. Many investors don't apportion chattels properly at purchase and miss the depreciation they're entitled to.
Because these rules have moved, confirm the current treatment with your accountant. The principle holds though: the building isn't depreciable, qualifying chattels generally are.
Why Underspending Costs You
Beyond tax, neglecting maintenance is an asset mistake:
A poorly maintained property leases for less and sits vacant longer
Small unaddressed problems become big expensive ones (a minor leak becomes rot)
The property's value erodes relative to well-maintained comparable stock
Healthy Homes and other compliance obligations don't wait
The money you "save" by underspending shows up later as lower rent, longer vacancy, bigger repair bills, and weaker sale value. It's a false economy.
The Smart Approach
Maintain proactively, it's cheaper than reactive repairs and it protects rent and value
Keep clear records, repairs and maintenance are deductible and you need the paper trail
Get the repair-versus-capital classification right (ask before major work)
Apportion and claim chattels depreciation properly at purchase
Treat maintenance spending as protecting your asset and your deductions, not as dead money
Where This Leaves You
Spending sensibly on your rental protects the asset and, for genuine repairs, reduces your tax. Underspending degrades the property and costs you more than you saved. And depreciation, while gone on the building, is still available on chattels and often underclaimed.
Maintain the asset, classify the spending correctly, claim what you're entitled to, and confirm the current depreciation rules with your accountant.
