What Is Depreciation?
A Simple Guide for Small Business Owners
If you run a small business, understanding how depreciation affects your profit is key to managing your tax and cash flow. Whether it’s a car, laptop, or coffee machine, depreciation helps you spread the cost of assets over time—and can reduce your taxable income.
📉 What Is Depreciation?
Depreciation is the process of spreading the cost of a business asset over its effective life. Instead of claiming the full cost in the year you buy it, you claim a portion each year as a tax deduction. This reflects the asset’s decline in value due to use, wear and tear, or obsolescence.
💡 Why Does Depreciation Matter?
- Tax Deductions: Depreciation reduces your taxable income, which can lower your tax bill.
- Accurate Financial Reporting: It helps you understand the true cost of running your business.
- Cash Flow Planning: Knowing what you can claim helps you plan for future expenses.
🛠️ What Assets Can You Depreciate?
Depreciating assets generally:
- Have a limited life expectancy (effective life)
- Are expected to decline in value over time
Examples include:
- Machinery and tools
- Computers and office equipment
- Motor vehicles
- Furniture and fittings
Assets that don’t depreciate: Land, trading stock, and most intangible assets.
📐 How Do You Calculate Depreciation?
Two main methods under the general depreciation rules:
1. Prime Cost (Straight-Line) Method
Spreads the cost evenly over the asset’s effective life.
2. Diminishing Value Method
Claims a higher deduction in the early years, reducing over time.
The Australian Taxation Office (ATO) provides guidelines on depreciation methods and rates depending on the asset type.
