Loss carry back is a tax incentive and part of the government's JobMaker Plan. Loss carry back is a refundable tax offset for eligible corporate entities (companies, corporate limited partnerships and public trading trusts). It allows them to carry back tax losses from the 2019–2020, 2020–2021 or 2021–2022 income years to offset income tax liabilities in the 2018–2019 income year or later.
