    Effective life determinations

    The effective life of a depreciating asset is used to work out the asset’s decline in value (or depreciation) which is used to claim an income tax deduction.

    We provide effective life determinations for either:

    • depreciating assets used by a particular industry
    • a single asset commonly used by different industries.

    We previously published a new effective life determination for certain depreciating assets each year. The determination is also published annually in a new taxation ruling (effective life ruling), see Taxation Ruling TR 2022/1 Income tax: effective life of depreciating assets (applicable from 1 July 2022).
