Depreciation is the decline in value of an asset over time due to wear and tear, age, or obsolescence. The Australian Taxation Office (ATO) allows you to claim this decline as a tax deduction.
Key Points:
Depreciation is the same amount every year (straight-line).
Annual = Cost ÷ Effective Life
Example: $10,000 laptop ÷ 4 years = $2,500/year
Higher deductions in early years, declining over time (accelerated).
Annual = Book Value × (200% ÷ Life)
Example: $10,000 laptop: Yr1 $5,000, Yr2 $2,500, Yr3 $1,250...
