Repairs are immediately deductible, while improvements must be capitalised and claimed over time under ATO rules
For Australian property investors, the distinction between repairs and improvements directly affects how and when you can claim tax deductions. The Australian Taxation Office (ATO) treats repairs as immediately deductible expenses, while improvements must be capitalised and claimed over time under Division 40 or Division 43.
Understanding this distinction is critical to avoid incorrect claims, compliance issues, and unnecessary ATO scrutiny.
Key takeaways
- Repairs restore an asset and are immediately deductible
- Improvements enhance or replace an asset and must be capitalised
- Initial repairs are not deductible
- Replacing an entire asset is usually capital expenditure
- Capital improvements may reduce capital gains tax (CGT) later
What is the difference between repairs and improvements?
A repair restores an asset to its original condition without changing its function, while an improvement enhances, upgrades, or replaces the asset.
Under ATO Tax Ruling TR 97/23, the key distinction is whether the work:
- Restores efficiency or function (repair)
- Improves or upgrades the asset (improvement)
Examples
| Scenario | Treatment |
| Fixing a leaking tap | Repair (immediately deductible) |
| Replacing a broken window (like-for-like) | Repair |
| Renovating an entire kitchen | Improvement (capital) |
| Upgrading carpet to timber flooring | Improvement |
When is a repair immediately deductible?
A repair is immediately deductible when it relates to wear and tear or damage that occurs while the property is producing rental income.
This typically includes work that:
- Fixes damage caused by tenants
- Restores the property to its original condition
- Maintains functionality without upgrading the asset
Examples include:
- Patching walls or repainting damaged areas
- Fixing plumbing or electrical faults
- Repairing part of a roof

What are initial repairs and why are they not deductible?
Initial repairs relate to defects that existed when you first acquired the property.
Even if the work looks like a repair, the ATO treats it as capital because it improves the property’s condition from what you originally purchased.
Common examples include:
- Fixing structural issues present at purchase
- Replacing damaged flooring immediately after acquisition
- Repairing pre-existing plumbing or electrical faults
These costs must be capitalised and cannot be claimed as an immediate deduction.
How does the ATO define an improvement?
An improvement occurs when the work goes beyond restoring the property and instead enhances its value, function, or lifespan.
This includes situations where the work:
- Replaces the entirety of an asset
- Upgrades materials or finishes
- Extends the useful life of the property
- Changes the property’s function or layout
Examples include:
- Full kitchen or bathroom renovations
- Structural extensions or additions
- Replacing laminate surfaces with stone
- Replacing an entire roof
These expenses are claimed over time under:
- Division 43 (Capital Works) for structural elements
- Division 40 (Depreciating Assets) for fixtures and fittings
Does replacing an entire asset count as a repair?
No. Replacing an entire asset is generally treated as a capital improvement.
The ATO applies the concept of an “entirety”:
- Repairing part of an asset → deductible
- Replacing the whole asset → capital
Example
- Replacing a few roof tiles → repair
- Replacing the entire roof → capital improvement
This is one of the most common areas where property investors make incorrect claims.
How do capital improvements affect capital gains tax?
Capital improvements are added to the property’s cost base, which can reduce the capital gain when the property is sold.
This means:
- You do not receive an immediate deduction
- But you may benefit later through a reduced CGT liability

How should property investors classify expenses correctly?
To correctly treat expenses for tax purposes, property investors should:
- Identify whether the work restores or improves the asset
- Assess the condition of the property at the time of purchase
- Determine whether part or all of the asset is being replaced
- Apply the correct ATO treatment (deduction vs capitalisation)
- Keep detailed records and documentation
Correct classification is critical for both compliance and long-term tax outcomes.
