As Australia’s 2026 tax season approaches, rental property owners and landlords across Sydney, the Central Coast, and NSW face a critical window of opportunity to maximize legitimate tax deductions. With the Australian Taxation Office (ATO) tightening compliance requirements and introducing clearer guidelines around rental property expenses, understanding exactly what maintenance and repairs you can claim has never been more important.
If you own one or more investment properties, you’re likely already familiar with the financial juggling act of property ownership: mortgage repayments, property management fees, insurance, and the never-ending cycle of maintenance. The good news? Many of these expenses—particularly plumbing, electrical, roofing, hot water systems, and blocked drain repairs—can significantly reduce your taxable income when claimed correctly.
However, the difference between an immediate tax deduction and a capital works claim spread over 40 years often comes down to a single word: repair versus improvement. Misclassifying these expenses can cost you thousands in denied deductions or trigger unwanted ATO audits.
In this comprehensive 2026 guide, WSG Group—trusted plumbing, electrical, and roofing experts since 1947—breaks down everything rental property owners need to know about claiming maintenance and repair rental property tax deductions. We’ll cover:
- What qualifies as an immediate tax deduction vs. capital works
- Specific examples of claimable plumbing, electrical, and roofing expenses
- Common mistakes that trigger ATO red flags
- How to document repairs for bulletproof claims
- Strategic timing for maximum tax benefits
Whether you’re a seasoned property investor or a first-time landlord, this guide will help you navigate the complex landscape of rental property tax deductions with confidence—and potentially save thousands of dollars before the June 30 EOFY deadline.
Understanding the ATO Framework: Repairs, Maintenance, and Capital Improvements
The foundation of claiming rental property tax deductions correctly starts with understanding how the ATO categorizes your expenses. According to the ATO’s Taxation Ruling TR 97/23 and updated 2026 guidance, there are three distinct categories:
1. Repairs (Immediate Deductions)
Repairs are expenses incurred to fix damage, deterioration, or wear and tear that occurred while your property was rented out or genuinely available for rent. These expenses restore something to its previous working condition without improving it beyond its original state.
Examples of immediately deductible repairs include:
- Fixing a leaking tap or burst pipe
- Replacing broken roof tiles (not the entire roof)
- Repairing a faulty electrical outlet or light switch
- Fixing a blocked drain or sewer line
- Replacing damaged sections of guttering
- Repairing a cracked window pane
- Patching holes in walls or ceilings
- Fixing a malfunctioning hot water system thermostat
- Repairing damaged floorboards (not replacing entire flooring)
2. Maintenance (Immediate Deductions)
Maintenance expenses prevent deterioration or address existing deterioration to keep your property in a tenantable condition. These are also immediately deductible.
Examples of deductible maintenance include:
- Repainting faded or damaged walls
- Cleaning gutters and downpipes
- Servicing hot water systems
- Pest control and termite inspections
- Garden maintenance and lawn mowing
- Pressure washing external surfaces
- Oiling decks and timber features
- Pool cleaning and chemical treatment
- HVAC system servicing
- Smoke alarm testing and battery replacement
3. Capital Improvements & Initial Repairs (Depreciated Over Time)
Capital improvements are expenses that improve the property beyond its original condition, increase its value, or extend its useful life. These cannot be claimed immediately but must be depreciated as capital works deductions over 40 years (at 2.5% per year).
Examples of capital improvements include:
- Complete roof replacement
- Full bathroom or kitchen renovation
- Installing a new hot water system (not repairing existing)
- Replacing entire plumbing or electrical systems
- Adding new rooms or structures
- Replacing an entire fence
- Installing air conditioning for the first time
- Replacing all windows or doors
- Complete rewiring of the property
- Structural repairs or extensions
⚠️ Critical Distinction: The “Entirety Test”
The ATO uses the ‘entirety test’ to determine whether you’ve repaired part of something (deductible) or replaced the whole thing (capital). For example:
| ✅ Repair (Immediate Deduction) | ❌ Capital (Depreciated) |
| Replacing 15 broken roof tiles | Replacing the entire roof |
| Fixing one electrical circuit | Complete rewiring of property |
| Repairing a leaking pipe section | Replacing entire plumbing system |
Plumbing Repairs & Maintenance: What You Can Claim
Plumbing issues are among the most common—and costly—maintenance needs for rental properties. Understanding what qualifies as an immediate deduction versus a capital expense is essential for landlords in Sydney and the Central Coast.
Immediately Deductible Plumbing Expenses
- Emergency call-outs for burst pipes or water leaks
- Fixing leaking taps, showers, or toilet cisterns
- Repairing or replacing damaged pipe sections
- Clearing blocked drains and sewer lines
- Fixing water pressure issues
- Repairing leaking hot water systems
- Replacing tap washers and valve components
- Fixing drainage problems in bathrooms or kitchens
- Repairing stormwater drainage systems
- Gas fitting repairs (not new installations)
Capital Plumbing Works (Depreciated)
- Installing a new hot water system (replacing existing)
- Complete repiping of the property
- Installing new plumbing for additions/renovations
- Upgrading from septic to sewer connection
- Installing new bathroom or kitchen plumbing
💡 Pro Tip for Landlords:
Keep detailed records of all plumbing call-outs, including invoices that clearly describe the work performed. If emergency repairs lead to discovering additional damage, ensure your plumber provides an itemized invoice separating repair costs from any improvement work.
Electrical Repairs & Maintenance: Deduction Guidelines
Electrical safety is paramount in rental properties, and fortunately, most routine electrical repairs qualify as immediate tax deductions. However, major electrical upgrades fall into the capital works category.
Immediately Deductible Electrical Expenses
- Repairing faulty power outlets and switches
- Fixing electrical safety hazards
- Replacing damaged light fixtures
- Repairing electrical appliances (oven, dishwasher, etc.)
- Safety switch testing and repairs
- Fixing wiring faults in specific circuits
- Replacing blown fuses or circuit breakers
- Repairing external lighting
- Fixing hot water system electrical components
- Emergency electrical call-outs
Capital Electrical Works (Depreciated)
- Complete property rewiring
- Switchboard upgrades or replacement
- Installing new electrical systems for extensions
- Adding new circuits or power points (improvements)
- Installing new air conditioning electrical work
- Solar panel installation
- Smart home electrical system installations
⚡ Safety & Compliance Note:
All electrical work on rental properties must be performed by licensed electricians and comply with NSW electrical safety standards. Always request certificates of compliance for your records—these documents are essential if the ATO queries your claims.
Roofing Repairs & Maintenance: Tax Treatment Explained
Roofing expenses can be particularly confusing for landlords because they often involve substantial costs. The key distinction lies in whether you’re repairing part of the roof or replacing the entire roofing system.
Immediately Deductible Roofing Expenses
- Repairing roof leaks
- Replacing damaged or broken roof tiles/shingles
- Fixing storm damage to sections of roof
- Repairing or replacing sections of guttering
- Fixing fascias and soffits
- Repairing flashing around chimneys or vents
- Cleaning gutters and downpipes
- Repairing roof valleys
- Patching roof membrane or waterproofing
- Emergency tarping and temporary repairs
Capital Roofing Works (Depreciated)
- Complete roof replacement
- Re-roofing the entire structure
- Replacing all guttering and downpipes
- Major structural roof repairs
- Installing new roofing for extensions
- Upgrading roof materials (e.g., tiles to metal)
- Installing new roof insulation
🏠 Real-World Example:
Storm damage: If a severe storm damages 30% of your roof tiles, replacing those specific tiles is a repair (immediate deduction). However, if you decide to replace the entire roof—even if only part was damaged—this becomes a capital improvement (depreciated over 40 years).
Hot Water Systems & Blocked Drains: Special Considerations
Two of the most common emergency calls for rental properties—hot water failures and blocked drains—have specific tax treatment that landlords should understand.
Hot Water System Tax Treatment
The tax treatment of hot water system expenses depends on whether you’re repairing or replacing:
| Scenario | Tax Treatment |
| Repairing existing system (thermostat, elements, valves) | Immediate deduction |
| Replacing entire hot water system | Capital works – depreciate over time |
Blocked Drain & Drainage Repairs
Immediately deductible blocked drain expenses:
- Emergency drain clearing (tree roots, blockages)
- CCTV drain inspections to locate issues
- High-pressure water jetting
- Repairing damaged drain sections
- Fixing collapsed stormwater drains
- Clearing sewer line blockages
Most blocked drain services are considered repairs and are immediately deductible. However, if you’re installing an entirely new drainage system or replacing all drainage infrastructure, this becomes a capital expense.
Documentation Requirements: Protecting Your Claims
The ATO’s scrutiny of rental property deductions has intensified in recent years. To protect your claims and avoid audits, meticulous record-keeping is non-negotiable.
Essential Documentation Checklist
✅ Tax invoices with ABN for all services
✅ Detailed itemized descriptions of work performed
✅ Before and after photos of damage/repairs
✅ Receipts for all materials and labor
✅ Contractor licenses and insurance certificates
✅ Property management reports documenting issues
✅ Tenant maintenance request records
✅ Bank statements or credit card records
✅ Written quotes for major works
✅ Certificates of compliance (electrical, plumbing)
Best Practices for Record-Keeping
- Create a dedicated folder (physical and digital) for each rental property
- Scan and digitally store all receipts immediately
- Request itemized invoices that separate repairs from improvements
- Keep records for 5 years after claiming deduction
- Document the timing of repairs relative to rental periods
- Note whether repairs address pre-existing damage or tenant-caused issues
- Maintain a maintenance log with dates and descriptions
- Store property condition reports from tenancy start/end
Common Mistakes That Trigger ATO Audits
Avoid these costly errors that commonly trigger ATO scrutiny of rental property claims:
Mistake #1: Claiming Initial Repairs as Immediate Deductions
Initial repairs—work to fix defects that existed when you purchased the property—cannot be claimed as immediate deductions, even if you were unaware of the problems. These must be claimed as capital works.
Mistake #2: Failing to Apportion Expenses Between Repairs and Improvements
If you simultaneously repair and improve a property (e.g., repainting damaged walls while also upgrading to premium paint finishes), you must apportion costs. Request itemized invoices that separate repair work from improvement work.
Mistake #3: Claiming Expenses While Property Is Not Genuinely Available for Rent
You can only claim rental expenses for periods when the property is rented out or genuinely available for rent. Using the property for personal holidays or extended vacancies without marketing efforts will disqualify claims.
Mistake #4: Misclassifying Capital Improvements as Repairs
Claiming a complete roof replacement or full bathroom renovation as an immediate repair deduction is a major red flag. When in doubt, consult with a tax professional or quantity surveyor.
Mistake #5: Inadequate Documentation
Claims without supporting invoices, receipts, or evidence of payment will be denied. The ATO requires contemporaneous records—you cannot recreate documentation years later.
Strategic Timing: Maximizing Your 2026 Tax Benefits
With EOFY 2026 approaching on June 30, strategic timing of maintenance and repairs can optimize your tax outcomes.
Pre-EOFY Action Items (February – June 2026)
- Schedule postponed maintenance work before June 30
- Conduct property inspections to identify deductible repairs
- Address tenant maintenance requests promptly
- Complete any planned repairs to maximize current-year deductions
- Order and receive depreciation schedules if not already obtained
- Review rental property insurance and ensure premiums are paid
- Finalize any professional services (property management, accounting)
Considerations for Bringing Forward Expenses
While you cannot artificially accelerate expenses solely for tax purposes, there are legitimate reasons to complete work before EOFY:
- Addressing safety hazards or compliance issues
- Preventing further property damage
- Improving tenant satisfaction and retention
- Preparing property for new tenancy
- Taking advantage of contractor availability
- Utilizing current-year rental income for offset
Working with Professional Service Providers
Choosing the right plumbing, electrical, and roofing contractors is essential—not just for quality work, but for proper tax documentation.

✅ Maintain professional communication and records
Questions to Ask Your Service Provider
- “Can you provide an itemized invoice for tax purposes?”

- “Can you document pre-existing damage with photos?”
Frequently Asked Questions (FAQ)
Q1: Can I claim plumbing repairs if the property is currently vacant?
Yes, provided the property is genuinely available for rent and the repairs relate to damage that occurred during a rental period. You cannot claim expenses for periods when the property is used privately or not genuinely available.
Q2: What if I do some repairs myself as a landlord?
You can only claim the cost of materials, not your labor. Keep receipts for all materials purchased. Professional repairs are generally more favorable for tax purposes because they include labor costs and provide proper documentation.
Q3: Are emergency call-out fees tax deductible?
Yes, emergency call-out fees for plumbing, electrical, or roofing issues are immediately deductible as repair expenses, provided they relate to rental property maintenance.
Q4: How do I know if something is a repair or improvement?
Ask yourself: Does this work restore the property to its previous condition (repair) or make it better than before (improvement)? When uncertain, consult a tax professional or refer to ATO Ruling TR 97/23.
Q5: Can I claim roof cleaning and gutter maintenance?
Yes, regular gutter cleaning and roof maintenance are immediately deductible as preventative maintenance expenses.
Q6: What happens if I claim incorrectly?
Incorrect claims can result in denied deductions, interest charges, penalties, and ATO audits. Always err on the side of caution and seek professional advice for significant expenses.
Q7: Do I need a depreciation schedule?
While not mandatory, a depreciation schedule prepared by a quantity surveyor can help you claim capital works deductions and depreciation on assets, potentially saving thousands annually.
Q8: Can I backdate claims for repairs done in previous years?
Generally, you can only claim expenses in the year they were incurred and paid. However, you may be able to amend previous tax returns (within certain time limits) if you missed legitimate deductions.
Conclusion: Take Control of Your Rental Property Tax Position
Navigating rental property tax deductions doesn’t have to be overwhelming. By understanding the critical distinction between repairs and capital improvements, maintaining meticulous records, and working with qualified professionals, you can confidently maximize your legitimate tax deductions while staying compliant with ATO requirements.
