Part I
Treatment of tax losses
General rules for tax losses
IA 10Amended assessments
This section applies if, in a tax year, the Commissioner amends under section 113 of the Tax Administration Act 1994 a person’s assessment for an earlier tax year, and the amendment adjusts the amount of a tax loss component or a ring-fenced tax loss for the earlier tax year.
If the amount is reduced in the adjustment, the person must reduce their loss balance or ring-fenced tax loss for the earlier tax year by the amount of the adjustment. If the loss balance or ring-fenced tax loss has been used in earlier tax years, they must similarly apply the reduction to the use of the loss balance or ring-fenced tax loss.
If the amount is increased in the adjustment, the person must add an amount to their loss balance or ring-fenced tax loss for the earlier tax year.
