Depreciation

Depreciation is the process of recognising the cost of a business asset over time as it wears out, ages, or loses value.

When a business buys a long-lasting asset, such as a computer, vehicle, machine, or fit-out, the full cost is not always treated like an ordinary expense straight away. Instead, the cost may be spread across the asset’s useful life.

For tax, the ATO describes this as claiming the decline in value of depreciating assets. The details can depend on the asset, business use, dates, and whether small business depreciation rules apply.

Where Depreciation Appears

You may see depreciation in:

fixed asset registers
accountant year-end journals
profit and loss statement expense lines
balance sheet asset values
tax return and deduction schedules
business sale or asset finance discussions

It often appears near CapEx - Capital Expenditures, because capital assets are usually the items that may be depreciated.

How Depreciation Works In Practice

Depreciation moves part of an asset’s cost into expenses over time. This helps the reports show that the asset is being used to earn income across more than one period.

The ATO’s depreciation and capital expenses guidance explains the general idea and points businesses to rules for capital allowances, simplified depreciation, instant asset write-off, and other asset deductions. Because thresholds and eligibility rules can change, check the current ATO guidance or your accountant before relying on a deduction.

Simple Example

A studio buys a $3,000 laptop for business use. Rather than treating the whole $3,000 as a normal operating expense in one month, the business may depreciate the laptop over its useful life or use a small business concession if eligible.

The laptop still exists as an asset, while depreciation records part of its cost as an expense over time.

Why Depreciation Matters

Depreciation affects profit, asset values, tax deductions, and business planning. If assets are not recorded properly, profit may look too high or too low, and the balance sheet may not reflect what the business owns.

It also matters for cash flow interpretation. Depreciation is an accounting expense, but it is not a new cash payment when the depreciation entry is recorded. The cash usually left the business when the asset was purchased.

Easy Way To Remember It

Depreciation is how the books recognise that useful assets get used up.

In Short

Depreciation spreads an asset’s cost across the time the business uses it. It helps reports reflect asset use, profit, and tax records more accurately.
