From 1 April 2020, the reporting requirements for investment income have changed.

Information requirements

Interest payers do not need to withhold tax on interest they pay if the:

  • interest is on funds that do not generate taxable income
  • amount of interest paid to generate taxable income is less than $5,000.

If this applies to you, the following information is required for each of the income recipients who received interest:

  • their name
  • their contact details
  • the amount and type of interest paid to them.

If it is available, you need to provide the following information for each of the income recipients who received interest:

  • their IRD number or foreign equivalent
  • their date of birth.

You must provide the name of any joint owners. If held, you also need to provide the following information for any joint owners:

  • IRD number
  • date of birth
  • contact address.

You will need to report this electronically unless you have an exemption.

This is all due when you file your income tax return.

Reporting requirements before 1 April 2020

Transitioning to the new investment income reporting requirements

Example: James borrows money to buy a house.

James borrowed $200,000 from his parents to buy a house and pays $12,000 of interest. James runs a taxable activity selling go-carts from his garage. The garage is 20% of the floor area of the house so $2,400 of the interest is attributed to his taxable activity. 

James does not have an RWT obligation in relation to the interest as only $2,400 of it relates to his taxable activity and this is less than $5,000.

James will instead need to file the investment income information described above with his return of income for the corresponding income year.
