Example: change affects the amount of tax losses available to be carried forward to or deducted in later income years

JKL Co is not a base rate entity. For the 2019–20 income year, JKL Co has a taxable income of $300,000, no net exempt income and income tax liability of $90,000.

For the:

  • 2020–21 income year    
    • JKL Co has a tax loss of $800,000 and chooses to carry back $300,000 of that loss to the 2019–20 income year
    • the amount of its tax offset is worked out to be $90,000
    • the amount of tax loss carried forward is $500,000
  • 2021–22 income year    
    • JKL Co has taxable income (before deducting tax losses) of $60,000
    • after deducting $60,000 of the remaining tax loss it carried forward, it has no taxable income and carries forward the remaining tax loss of $440,000
  • 2022–23 income year    
    • JKL Co has taxable income (before deducting tax losses) of $290,000
    • after deducting $290,000 of the remaining tax loss it carried forward, it has no taxable income and carries forward the remaining tax loss of $150,000.

JKL Co's assessment for the 2019–20 income year is subsequently amended to increase the taxable income to $600,000, resulting in tax payable of $180,000.

JKL Co notifies us, using the Loss carry back change in choice schedule 2021 that it has changed its original loss carry back choice for the 2020–21 income year to increase the amount of tax loss carried back to the 2019–20 income year from $300,000 to $600,000. The tax offset for the 2020–21 income year is increased to $180,000 and the amount of tax loss carried forward is reduced to $200,000.

As a result:

  • JKL Co will still have no taxable income in the 2021–22 income year but the tax loss remaining to be carried forward in the 2021–22 income year is reduced to $140,000
  • JKL Co lodges an amendment request for the 2022–23 income year, as JKL Co only has $140,000 of tax loss available to be deducted, resulting in a taxable income of $150,000.
