7 Commercial Tax Tricks Most Investors Don't Know Exist

Commercial vs Residential Depreciation: Key Differences

Commercial properties enjoy significant advantages over residential properties when it comes to depreciation. The most important difference is that commercial properties are completely exempt from the 2017 legislation changes that restricted Division 40 (plant and equipment) deductions for second-hand residential properties.

This means that when you purchase an existing commercial property, you can claim depreciation on all existing plant and equipment—from air conditioning systems to carpet to fit-out items—regardless of their age or previous ownership. This alone can add tens of thousands of dollars to your annual deductions.

Commercial properties also typically have higher capital values and more extensive fit-outs than residential properties, resulting in larger absolute deduction amounts.

Strategy 1: Claim Building Structure at 2.5%

The building structure of commercial properties built after 20 July 1982 (or 21 August 1984 for some property types) qualifies for capital works deductions at 2.5% per year. For a commercial building with a construction cost of $2 million, this represents $50,000 per year in deductions for 40 years.

Importantly, the construction cost is typically estimated based on the property's age, size, and quality, not its purchase price. A quantity surveyor uses construction cost indices to estimate what it would have cost to build the property at the time of construction, which often results in higher deductions than investors expect.

Strategy 2: Maximise Plant and Equipment (Division 40)

Commercial properties typically have extensive plant and equipment that qualifies for accelerated depreciation. Common high-value items include:

• HVAC systems: Commercial air conditioning can be worth $50,000-$500,000+
• Lifts and escalators: Major assets in multi-story buildings
• Fire protection systems: Sprinklers, alarms, and suppression equipment
• Security systems: Access control, CCTV, and alarm systems
• Fit-out items: Carpet, partitions, ceilings, and lighting
• Kitchen equipment: In hospitality and food service properties

These items depreciate at rates of 5-20% per year under the diminishing value method, providing substantial deductions in the early years of ownership.

Strategy 3: Claim Tenant Fit-Out Contributions

When tenants make improvements to commercial premises, these can create depreciation entitlements for the property owner. Even if the tenant paid for the fit-out, the items may become the property of the landlord and therefore depreciable by them.

Common tenant fit-out items include:

• Office partitions and workstations
• Specialised electrical and data cabling
• Reception areas and signage
• Kitchen and bathroom upgrades
• Floor coverings and ceiling treatments

Lease agreements should be reviewed carefully to determine ownership of fit-out items and corresponding depreciation entitlements.

Strategy 4: Scrapping Deductions on Disposal

When plant and equipment items are disposed of, scrapped, or replaced, you can claim an immediate deduction for the remaining written-down value. This "scrapping" deduction can be substantial when renovating or refurbishing commercial premises.

For example, if you replace a carpet that has a written-down value of $15,000, you can claim the entire $15,000 as an immediate deduction in the year of replacement, plus begin depreciating the new carpet from its full cost.

This strategy is particularly valuable during major refurbishments where multiple items are being replaced. A quantity surveyor can prepare a report identifying all items being scrapped and their written-down values for immediate deduction.

Strategy 5: Low-Value Pooling for Efficiency

Items costing less than $1,000 can be allocated to a low-value pool and depreciated at a flat rate of 37.5% per year. This provides faster deductions than standard depreciation rates for many items and simplifies record-keeping.

Commercial properties often contain hundreds of low-value items that qualify for pooling:

• Light fittings and switches
• Smoke detectors and exit signs
• Door hardware and locks
• Small appliances and equipment
• Bathroom accessories

Strategy 6: Immediate Asset Write-Off

Under certain conditions, businesses can immediately write off the full cost of eligible assets rather than depreciating them over time. While specific rules change with federal budgets, various instant asset write-off provisions have applied to assets costing up to $150,000 or more.

Check current legislation and consult your accountant to determine which assets in your commercial property may qualify for immediate deduction rather than standard depreciation.

Strategy 7: Site Works and Improvements

External site works can also be depreciated, though the rules differ from building structures. Depreciable site improvements include:

• Car parks and driveways: Sealed surfaces and line markings
• Fencing and gates: Security and boundary fencing
• Landscaping structures: Retaining walls and permanent installations
• Signage: External building and directory signage
• Outdoor lighting: Security and decorative lighting

These items are often overlooked in depreciation schedules but can add significant value over time.

Conclusion: Maximise Your Commercial Property Returns

Commercial property depreciation offers some of the most valuable tax benefits available to investors. With no restrictions on plant and equipment deductions, higher capital values, and extensive fit-outs, commercial properties can generate substantial deductions that significantly improve cash flow and returns.

A professional depreciation schedule prepared by a chartered quantity surveyor ensures you capture every available deduction across all seven strategies. The investment in a quality schedule typically pays for itself within the first year and continues to provide value for decades.
