Section 73: How relief works
274.This section sets out the order in which losses, for which a claim is made under section 72, are deducted from income of the three preceding tax years. It is based on section 381(2) of ICTA.
275.The deduction for the loss is made first from income of the earliest of the three tax years referred to in subsection (2) of section 72, with any remaining loss deducted from income of the next tax year and then from income of the third of those tax years. Any remaining loss is available for a different loss relief claim.
