A repair fixes something that has worn out, been damaged or deteriorated while your property is rented. An improvement makes the property better, more valuable or different in character. The Australian Taxation Office (ATO) treats them differently: repairs and maintenance are generally deductible in the income year you incur them, while improvements are capital and are recovered over time. Getting the label right affects your tax return, your records and your maintenance planning.
This guide sets out the test, gives worked examples, covers the traps (initial repairs, full replacements and mixed jobs) and explains what to keep on file. It is general information, not tax advice. For your own return, speak with a registered tax agent or accountant.
TL;DR
- A repair restores something damaged or worn from renting the property. It is generally deductible in the year you pay for it.
- An improvement, renovation, extension or complete replacement is capital. It is claimed over several years, not at once.
- Fixing damage that existed when you bought the property is an initial repair. It is not an immediate deduction, even if you did not know about the damage.
- Mixed jobs need an itemised invoice so each part can be claimed correctly.
- Keep dates, costs, contractor details and photos for every job, repair or improvement.

The test the ATO applies
The ATO draws three lines. A repair restores a defective, damaged or deteriorated item. Maintenance prevents or fixes deterioration and keeps the property tenantable. An improvement makes the property better, more valuable or more desirable, changes its character, or is a renovation.
In practice, ask four questions about any job:
- Is the work fixing something that broke or wore out?
- Did that damage or wear happen while the property was rented or available for rent?
- Does the result simply return the item to its earlier working condition?
- Or does it add something new, extend the property's life, or lift it above its previous standard?
Yes to the first three points towards a repair. Yes to the fourth points towards a capital improvement. The ATO's capital expenses guidance describes capital work as providing something new, furthering the property's income-producing ability or expected life, or going beyond restoring efficient function.
Our own quick-reference version of this test is in our guide to capital works vs repairs for SA landlords.
Repair, maintenance or improvement: examples side by side
The ATO publishes a table of rental upkeep categories. The examples below follow it.
| Job | Category | Usual treatment |
|---|---|---|
| Replacing the storm-damaged section of a fence | Repair | Deductible in the year incurred |
| Fixing a leaking tap | Repair | Deductible in the year incurred |
| Repainting faded interior walls | Maintenance | Deductible in the year incurred |
| Re-oiling a deck | Maintenance | Deductible in the year incurred |
| Replacing an entire fence | Capital works | Claimed over time |
| Adding a carport | Capital works | Claimed over time |
| Renovating a bathroom | Capital works | Claimed over time |
| Installing a new dishwasher | Depreciating asset | Claimed as decline in value |
| Installing new blinds | Depreciating asset | Claimed as decline in value |
The pattern is consistent. Part of something is usually a repair. The whole of something is usually capital. The ATO's Rental properties guide 2025 states that replacing an entire structure or unit, such as a complete fence, stove, kitchen cupboards or curtains, is capital rather than repair or maintenance.
Maintenance is part of holding the asset well
Maintenance is the routine work that stops small problems becoming large ones: servicing, clearing gutters, resealing, repainting worn surfaces. The ATO says repairs and maintenance cover keeping the property tenantable and fixing wear, tear or damage that occurs while it is rented. Planned maintenance also protects rental appeal, which is why we build it into budgets. Our piece on the rental maintenance budget Adelaide landlords use covers how to set aside funds for it.
The condition that catches landlords out: the property must be rented
A repair is deductible when the work relates to wear, tear or damage arising while the property was rented, and the property remains rented or genuinely available for rent on commercial terms. If you repair a property and then move in, or you hold it off the market at a rent no one would pay, the deduction is at risk.
Two more points from the ATO:
- Your own labour is not deductible. Qualifying materials you buy for the job may be.
- If an insurer pays for the repair, you cannot claim it. The ATO's Rental properties guide 2026 also says insurance or compensation received for work you previously claimed must be included in your income.
If you are weighing up a claim against your policy, see our walkthrough of the landlord insurance claim process for SA owners.
Initial repairs: damage that existed when you bought
This is the most common source of mistakes among new investors. The ATO treats work that corrects damage, defects or deterioration existing when you purchased the property as an initial repair. It is not an immediate deduction, even if you did not know about the problem. Qualifying building or structural initial repairs may generally be claimed as capital works over 40 years.
The ATO's 2025 example is useful. A landlord repainted dirty walls, replaced broken light fittings, repaired doors and replaced termite-damaged floorboards before the first tenants moved in. The work was capital in nature, because it made the property suitable to rent rather than resulting from income-producing use.
For Adelaide investors, this matters at purchase. Think of an older character home in Prospect or Norwood with tired floors and worn fittings, or a coastal unit at Glenelg or Semaphore with weathered balcony timber. If the defects were there at settlement, the clean-up is not a same-year repair. A pre-purchase building inspection gives you a dated record of the property's condition, which helps separate initial repairs from later wear.
The same logic applies to newly built homes. Defects present at handover are a builder or warranty matter first, not a repair expense. Our guide to new build rental defects for South Australian landlords explains how to handle them.
Replacing a whole item versus repairing part of it
Scale decides many cases. Patching a section of fence is a repair. Replacing the whole fence is capital works. Fixing a stove element is a repair. Replacing the stove is a different category.
The ATO treats these replacements in two ways:
- Structural items (a fence, carport, kitchen cupboards, a bathroom) fall under capital works, generally claimed at a set rate over 40 years from completion. The ATO's capital works guidance says this is limited to income-producing use.
- Depreciating assets (appliances, blinds, carpet that can be removed, air conditioners) are claimed through decline-in-value rules over each asset's effective life.
There is a further wrinkle. The Rental properties guide 2026 says that replacing an entire depreciating asset, such as a stove or air conditioner, may trigger a balancing adjustment event, while the replacement asset may qualify for its own decline-in-value deductions. Your accountant should handle the balancing adjustment, so tell them when an old appliance is removed.
Mixed jobs and why the invoice matters
Many jobs are part repair, part improvement. The ATO's example: replacing an entire toilet is claimed as capital works, while replastering and painting the surrounding wall to restore it is an immediate repair. An itemised invoice is needed to separate the two claims.
The practical lesson is to brief contractors before work starts. Ask for quotes and invoices that list each task and its price separately: demolition, new fixtures, making good, painting. A single line reading "bathroom works" leaves your accountant guessing and weakens your position if the ATO asks questions.
What happens to improvements over time
Improvements are not lost money for tax purposes. They are recovered differently.
- Capital works deductions. Structural costs may generally be claimed over 40 years from completion, limited to income-producing use.
- Decline-in-value deductions. Eligible depreciating assets are written off over their effective life.
- Capital gains tax (CGT) cost base. The Rental properties guide 2026 says capital expenses may form part of the property's CGT cost base, generally excluding amounts for which capital-works deductions have been or can be claimed.
The ATO's overview of rental expenses groups everything into three buckets: deductions now, deductions over several years, and expenses you cannot claim. Repairs and maintenance sit in the first bucket. Capital works and depreciation sit in the second.
For how improvements relate to long-term returns, see our explainer on rental property capital growth for investors. For the wider picture of what South Australian owners must report, see our SA rental property tax obligations guide.
Records to keep for every job
For capital works, the ATO says to keep construction details: the type of construction, commencement and completion dates, the construction cost, who carried out the work and the period the property was used to produce income. The ATO's capital works page makes this central because the deduction period and eligibility depend on those dates, costs and income-producing use.
A simple file for each job should hold:
- The quote, the itemised tax invoice and proof of payment
- The contractor's name and business details
- Dates the work started and finished
- Photos before, during and after
- The reason for the work (tenant report, inspection finding, storm damage, purchase condition)
- Any insurer correspondence
The reason for the work matters most. A routine inspection note saying "gutter rusted through after winter storms" supports a repair claim. A note saying "owner upgrading kitchen" supports a capital one. Good records are also the base of a sound maintenance history, which we cover in our examples of well-maintained rental properties.
Repairs, improvements and your tenant
The tax label is one question. The tenancy obligation is another. Urgent faults, such as a failed hot water service or a gas leak, cannot wait for a tax decision. Non-urgent items still need a clear process and timeframe. Our guide to non-urgent repairs in SA for 2026 sets out how to handle them. If a repair dispute with a tenant cannot be resolved, South Australian landlords can take it to SACAT, so keep your records tidy from the start. Repairs completed promptly and documented well protect the asset and the tenancy.
One more point for owners who pay GST on works: residential rent is input-taxed, so there are no GST credits on it. We explain the position in our note on GST and residential rent.
Our perspective
Most repair-versus-improvement problems start before the tradesperson arrives. The owner approves a job without a clear description, the invoice is vague, and the tax category is guessed at the end of the year.
Because we focus exclusively on property management, not sales, maintenance control is part of our daily work. We coordinate maintenance, run routine inspections and keep job records in one place. Our 24/7 owner portal is designed to give you visibility of what was done and when.
Our advice to Adelaide landlords is consistent. Decide the purpose of the work first: restore, maintain or upgrade. Ask for itemised quotes. Photograph the condition before work begins. Then give your accountant a complete file.
For interstate and overseas investors, this discipline matters even more. You cannot walk the property, so the record has to carry the proof.
HOSO
How HOSO supports your maintenance decisions
We manage Adelaide rentals with inspections, maintenance coordination and compliance management, and we screen tenants through our 4-layer system to help protect the asset from the start. If you want a property manager who documents every job properly, see our property management services. If you are unsure what your property should earn before you invest in upgrades, start with a rental appraisal.
Planning upgrades that earn their place
Once the repairs are done, upgrades are a business decision. Before you commit, consider:
- Tenant demand. Which features do renters in your suburb pay for: efficient cooling, secure parking, low-maintenance yards, modern bathrooms?
- Durability. Choose finishes that stand up to tenancy wear, and avoid fragile ones.
- Timing. Schedule larger works between tenancies where possible, so the property is not disrupted and vacancy is limited.
- Tax treatment. Know in advance that an upgrade is claimed over time, not in one year. Plan cash flow accordingly.
- Compliance. Confirm that new fittings and works meet current requirements before the tenant moves in.
When you can, pair upgrades with repairs in the same visit, but invoice them separately. That keeps the claims clean and the owner reports readable.
FAQ
Can I claim a repair in the same year I pay for it?
Generally yes, when the work fixes wear, tear or damage that arose while the property was rented or available for rent. The ATO says eligible repair and maintenance costs are generally deductible in the income year incurred. Initial repairs and improvements are treated differently.
Is painting a repair or an improvement?
Repainting faded or worn walls is maintenance, so it is generally deductible. Painting as part of a renovation, or to fix damage that existed at purchase, is capital. The ATO's examples list faded interior walls as maintenance and renovating as capital works.
What if I replace an appliance?
A brand-new dishwasher is a depreciating asset, so you claim its decline in value over time. Replacing an entire appliance such as a stove or air conditioner may also trigger a balancing adjustment event for the old one. Ask your accountant how to treat both.
Can I claim the cost of doing the work myself?
No. The ATO says your own labour is not deductible. Qualifying materials you buy may be, depending on the nature of the work.
How long should I keep records?
Keep them for as long as you own the property, and for the period the ATO requires after your final claim or sale. For capital works, the dates, costs and contractor details matter for decades because deductions run up to 40 years. Confirm current retention periods with your tax agent.
