Maintenance and Repair Deductions
A practical accounting and tax guide to classify property spend correctly: what you can claim now, what must be treated as capital works, and what is plant and equipment to depreciate over time.
Why Classification Matters
For tax purposes, the same invoice can have very different outcomes depending on how it is classified. The three buckets below determine whether you get an immediate deduction, a depreciation claim over time, or a capital-cost-base adjustment.
Immediately Deductible Repairs/Maintenance
Claimed in the year incurred when costs restore an asset to working condition without upgrading.
Capital Improvements (Capital Works)
Generally claimed at 2.5% per year over 40 years where eligible. Also affects CGT cost base.
Plant and Equipment
Depreciated under effective life rules (Division 40), typically over 5–15 years depending on asset type.
Warning: Misclassifying upgrades as immediate repairs can lead to amended returns, penalties, and interest charges. Keep clear evidence for each classification.
Rule of Thumb: If it's restoration, claim it immediately. If it's an improvement, capitalize it (capital works or plant depreciation). If you're replacing like-for-like, claim immediately. If replacing and upgrading, split the invoice and capitalize the upgrade portion.
What Can Be Claimed Immediately
You can generally claim maintenance and repair costs immediately when they restore an existing item to working condition without significantly improving or replacing substantially the whole asset.
Ask Yourself:
- Does it restore the item to its previous working condition without upgrading it?
- Are you replacing a broken part with a similar or equivalent item?
- Is the cost relatively minor compared to replacing the whole asset?
- Did the damage or wear occur after you purchased the property (not a pre-existing defect)?
If yes to all: Generally an immediate deduction.
Common Examples:
- Plumbing repairs: Fixing a leaking tap, unblocking drains, repairing burst pipes
- Electrical repairs: Replacing a broken switch, fixing faulty wiring, repairing light fixtures
- Minor replacements: Replacing broken door handles, damaged locks, cracked tiles (like-for-like)
- Routine maintenance: Servicing air conditioning, clearing gutters, pest control, lawn mowing
- Tenant damage repairs: Patching holes in walls, replacing broken windows, repairing damaged carpet sections
- Painting: Repainting existing surfaces in same or similar color (maintenance, not improvement)
Example - Benchtop Replacement (Tenant Damage):
Tenant burns and damages the kitchen benchtop beyond repair.
Scenario A - Replace with same material/style: $2,500
Tax treatment: Immediately deductible as a repair/maintenance expense. Claim the full $2,500 in the year incurred. (Like-for-like restoration to original condition.)
Scenario B - Replace with premium stone benchtop (upgrade): $2,500
Tax treatment: $1,500 (equivalent replacement) + $1,000 (premium upgrade). Depreciate $1,500 as plant at 10 years; consider $1,000 as capital improvement.
Why: Restoring the asset is depreciation; upgrading beyond original is capital.

Why: Restoring the asset is depreciation; upgrading beyond original is capital.
Mint's Fresh Take
Think “restore” vs “upgrade”. If the spend restores prior condition, it is usually immediate. If it upgrades, extends life materially, or replaces substantially the whole thing, it is usually capital.
What Is Capital Improvement (Capital Works)
Capital improvements are generally structural works or major enhancements that improve, extend, or replace key parts of the building.
Ask Yourself:
- Does it improve the property beyond its original state or function?
- Are you replacing a damaged/failed component to restore function, or replacing the entire system with a new one?
- Does it add something new that didn't exist before (extension, deck, pool)?
- Is it structural work that becomes a permanent part of the building?
- Was the defect present when you purchased the property (initial repair)?
If yes to any: Likely a capital improvement (depreciate at 2.5%/year if eligible, and add to CGT cost base).
Special Case: Like-for-Like vs Upgrade
When you replace a complete asset, the treatment depends on whether you're restoring or improving:
- Like-for-like replacement (restoring): Replacing a failed toilet with an identical model, or a burned benchtop with equivalent material. Immediately deductible as a repair/maintenance expense because it restores to the original condition without improvement.
- Replacement with upgrade: Replacing a toilet with a luxury model, or a basic benchtop with premium stone. The upgrade portion may be capital and need to be capitalized separately.
- Split treatment (replacement + extension): You can split invoices: claim the replacement (like-for-like) portion immediately as a repair, and capitalize the extension/upgrade portion separately.
Example - Split Treatment:
Your fence is damaged. You replace 20m like-for-like AND extend it by 5m new length.
Invoice: $8,000 (20m replacement) + $2,000 (5m extension) = $10,000 total
Tax treatment:
• 20m replacement (fence = plant/structure): Depreciate as capital works at 2.5%/year
• 5m extension (new capital improvement): Depreciate at 2.5%/year + add to CGT base
Both portions are capitalized, but you've correctly separated the like-for-like replacement from the improvement.

• 5m extension (new capital improvement): Depreciate at 2.5%/year + add to CGT base
Both portions are capitalized, but you've correctly separated the like-for-like replacement from the improvement.
Important: Claim replacement separately from upgrade on invoices where possible. Ask your contractor to itemize: "20m fence replacement" vs "5m new fence extension" so classification is clear.
Common Examples:
- Kitchen/bathroom renovations: Structural changes, new cabinetry, retiling, layout changes
- Extensions: Adding new rooms, sunrooms, second stories
- Outdoor structures: Decks, pergolas, retaining walls, carports, sheds
- Major replacements: Complete roof replacement, replacing entire floor system
- Structural upgrades: Replacing windows throughout, new fencing, driveway installation
- Initial repairs: Fixing defects that existed at purchase (often capital, not deductible)
Example - Capital Works:
You renovate the bathroom with new tiles, built-in vanity, structural plumbing changes, and better fixtures.
Invoice: $18,000 (structural work only)
Tax treatment: Add to capital works schedule. Claim 2.5% per year = $450/year for 40 years (if property is post-1987).
Also: Add $18,000 to CGT cost base (minus any depreciation claimed when you sell).
Why: Major structural improvement, not just restoring existing condition.

What Is Plant and Equipment (Depreciated)
Plant and equipment covers removable or mechanical assets with their own effective life. These are usually depreciated under Division 40 rather than claimed in full immediately.
Ask Yourself:
- Is it a removable or mechanical item (not fixed to the building structure)?
- Does it have a defined effective life (appliances, carpets, blinds, fixtures)?
- Could you take it with you if you sold the property (even if you wouldn't)?
- Does it cost more than a few hundred dollars?
If yes to most: Depreciate under Division 40 over its effective life.
Common Examples:
- Floor coverings: Carpets, vinyl, floating timber (effective life typically 8-10 years)
- Window treatments: Blinds, curtains (effective life 5-10 years)
- Appliances: Ovens, cooktops, dishwashers, rangehoods (effective life 8-12 years)
- Climate control: Air conditioners, ceiling fans, heaters (effective life 10-15 years)
- Hot water systems: Gas, electric, solar (effective life 8-12 years)
- Security/safety: Smoke alarms, alarm systems, security cameras (effective life 5-8 years)
Example - Plant & Equipment Depreciation:
You install a new dishwasher and air conditioning unit.
Dishwasher cost: $1,200 (effective life: 8 years)
Air conditioner cost: $3,500 (effective life: 10 years)
Tax treatment:
- Dishwasher: $1,200 ÷ 8 = $150/year depreciation
- Air conditioner: $3,500 ÷ 10 = $350/year depreciation
Total annual deduction: $500/year
Why: These are removable assets with defined effective lives, depreciated under Division 40.

Important: For properties purchased after 9 May 2017, you can only depreciate plant and equipment items you purchase and install yourself (not second-hand items already in the property).

Mint Tip
Always ask contractors to itemize invoices by category (repairs vs structural vs equipment) to make classification easier at tax time.
Accounting Workflow You Can Use Each Year
A practical approach is to classify each invoice at the time you enter it:
- Step 1: Is it restoration only? → classify as immediate repair/maintenance.
- Step 2: Is it structural upgrade or major replacement? → classify as capital works.
- Step 3: Is it a removable asset with an effective life? → classify as plant and equipment depreciation.
- Step 4: Store invoice, date, notes, and before/after photos for support.
Keep records for at least 5 years from lodgement (or longer where relevant to CGT record-keeping).
Common Mistakes to Avoid
- Treating renovations as repairs: Large-scale updates that improve the property are capital expenses.
- Claiming initial repairs: Defects existing at purchase are generally capital, not deductible.
- Upgrading beyond "like for like": Replacing a basic item with a premium version is an improvement.
- Poor documentation: Without invoices and photos, the ATO may disallow your claim.
- Bundling repairs with improvements: Separate invoices for repairs vs improvements to avoid disallowance.

Mint's Takeaway
- Classify every spend into one of three buckets: immediate repair, capital works, or plant and equipment depreciation.
- Immediate deductions are generally for restoration/maintenance, not upgrades.
- Capital improvements are usually claimed over time and can also impact CGT cost base.
- Plant and equipment is depreciated using effective life rules, not usually expensed in full up front.
- Good records (invoice + description + evidence) are essential for defensible tax treatment.
Mint helps you tag each invoice correctly and keep depreciation/capital tracking in one place so tax time is faster and cleaner.
