  • Draft effective life determinations: mineral processing and metallurgical laboratory industry

    We are seeking feedback on the draft list of effective lives for assets used in the scientific testing and analysis services (mineral processing and metallurgical laboratory) industry.

    Comments are open until 15 March 2019.

    Proposed new determinations

    We propose adding the following list of effective life determinations to the Commissioner's schedule to apply to assets purchased (or otherwise first used or installed ready to use) on or after 1 July 2019 (within the meaning of section 40-95 of the Income Tax Assessment Act 1997).
