Depreciation allows you to spread the cost of business assets over their useful life, reducing your taxable income each year. Understanding depreciation methods, rates and any instant write-off thresholds in your country can significantly impact your tax position. Proper depreciation tracking also gives you an accurate picture of your business's true financial position on the balance sheet.
Identify all depreciable business assets (equipment, vehicles, furniture, technology)
Determine the cost base of each asset (purchase price + installation costs)
Choose the appropriate depreciation method (straight-line or diminishing value)
Check for any instant asset write-off or immediate expensing thresholds
Calculate annual depreciation using the effective life or rate for each asset
Record depreciation journal entries in your accounting software
Maintain an asset register with all asset details and depreciation history
Review and update the register when assets are disposed of or written off
Businesses in Singapore operating under the GST system must meet these compliance requirements set by IRAS:
Not claiming depreciation at all on eligible assets
Using the wrong effective life or depreciation rate
Not taking advantage of instant asset write-off provisions
Forgetting to include installation and delivery costs in the asset cost base
Not recording asset disposals and removing them from the register
Depreciating assets below their residual value

Straight-line depreciation spreads the cost evenly over the asset's useful life (e.g., $10,000 asset over 5 years = $2,000/year). Diminishing value applies a percentage to the remaining book value each year, giving larger deductions in early years. The best method depends on your country's rules and tax strategy.
Many countries offer immediate expensing for assets below certain thresholds. Australia has the $20,000 instant asset write-off for small businesses. The UK has the Annual Investment Allowance (AIA). The US has Section 179 and bonus depreciation. Check your country's current thresholds.
SortBooks tracks your asset purchases in Xero and ensures they are correctly categorised as capital expenditure rather than expenses. It works with Xero's fixed asset register to ensure depreciation is calculated correctly each period.
