Simplified depreciation – rules and calculations

This information is for bookkeepers, tax practitioners and others who are applying or advising on the simplified depreciation rules for small businesses.

It sets out the detailed rules and how to calculate depreciation for eligible small businesses that have chosen to apply simplified depreciation.

You can choose to use the simplified depreciation rules if you have a small business with an aggregated annual turnover of less than $2 million.

Under these rules you:

  • immediately write-off – that is, claim their full cost in the year you buy them – most depreciating assets costing less than $20,000 (the current instant asset write-off threshold)
  • pool most higher cost assets (those with a cost equal to or more than the current instant asset write-off threshold) and claim  
    • a 15% deduction in the year you buy them
    • a 30% deduction each year after the first year
  • deduct the balance of your small business pool at the end of the income year if the balance at that time (before applying the depreciation deductions) is less than the instant asset write-off threshold.

If you choose to use the simplified depreciation rules, you must:

  • use them to work out deductions for all your depreciating assets except those specifically excluded, and
  • apply the entire set of rules, not just individual elements (such as the instant asset write-off).

You may choose to stop using the simplified depreciation rules or become ineligible to use them, in which case you'll then use the general depreciation rules.
