Income tax: effective life of depreciating assets

Taxation Ruling TR 2000/18 discussed the methodology used by the Commissioner of Taxation in making determinations of the effective life of depreciating assets under section 40-100 of the Income Tax Assessment Act 1997 . It also provided effective lives schedules determined by the Commissioner.

TR 2000/18 is being replaced by Taxation Ruling TR 2006/5 due to a change in the system of public rulings following the enactment of the Tax Laws Amendment (Improvements to Self Assessment) Act (No. 2) 2005 . The category of legally binding rulings has been expanded to cover matters about the administration and collection of particular taxes, including income tax.
