Deductions for bad debts

Learn which deductions claimed for bad debts attract our attention.

Last updated 30 January 2026

We focus on deductions claimed for bad debts, in particular:

  • the genuine nature of bad debts
  • whether it is correct to treat the debt as bad
  • arm's length treatment of debts within closely held groups
  • the treatment, by related entities, of income reflecting the debt
  • the documentation and evidence supporting the claims.

We also look at the correct application of the deduction rules, in particular:

  • the period when the debts were written off
  • the amount being claimed
  • whether there is a lending business or the debt is included in income
  • the rules being used for individuals, companies and trusts.
