Property depreciation is one of the most powerful tax deductions for Australian property investors — yet over 80% of investors don't claim it properly. A depreciation schedule from a quantity surveyor typically identifies $5,000-$15,000 in first-year deductions for an established property, and $15,000-$25,000+ for new builds. There are two types: Division 43 (capital works — the building itself at 2.5% p.a.) and Division 40 (plant & equipment — carpets, blinds, appliances). The 2017 changes restricted plant & equipment claims on second-hand properties, but building depreciation remains fully claimable.

§ Worked examples

Real-world scenarios

5-Year-Old Apartment

2-bed apartment built in 2021, purchased for $650,000. Estimated construction cost $350,000.

Division 43 (building): $8,750/year for 35 remaining years. Division 40 (plant & equipment): ~$4,500 in Year 1, declining. Total Year 1 depreciation: ~$13,250. At 37% tax rate, that's a $4,903 tax refund. Over 5 years: ~$55,000 in deductions = ~$20,350 in refunds.
