How is peer-to-peer lending interest taxed in New Zealand?

Interest earned through peer-to-peer lending is generally treated as taxable income in New Zealand, and platforms often deduct resident withholding tax before paying a lender. Specific rules can apply to a loss from a defaulted peer-to-peer loan. This is general information only, not tax advice. Every lender's position is different, and lenders should get their own advice from a tax professional or Inland Revenue before relying on it.

Interest income is generally taxable

Platforms typically deduct resident withholding tax (RWT) at source before paying a lender, similar to other New Zealand interest-bearing investments. A lender is responsible for declaring this income as required in their own tax return.

Records worth keeping

Keep the following records for each tax year:

  • statements or records from the platform showing interest paid and any tax withheld
  • records of amounts lent to, and repaid by, each opportunity
  • records of any default or shortfall on a specific loan

What happens with a loss

New Zealand has specific tax provisions that can, in some circumstances, allow a deduction for a loss on a defaulted peer-to-peer loan. Whether this applies, and how, depends on individual circumstances and is a question for a tax professional or Inland Revenue, not something LendCap advises on.
