Include interest from all New Zealand sources at Question 11.
The interest payer will usually send you an RWT withholding certificate (IR15), or similar statement, showing the gross interest paid and the amount of RWT deducted.
Write the total of all RWT deducted in Box 11A. Add up all the gross interest amounts (before the deduction of any tax) and write the total in Box 11B.
If expenses are deductible against the interest income (for example, commission), claim them at Question 23. Read the note about Expenses.
Don’t send in any interest statements or IR15 certificates with your return, but keep them in case Inland Revenue ask for them later.
If you’ve broken a term deposit during the year, you may have to account for “negative interest”. This is interest repaid on a term deposit and may reduce the amount of interest to declare in your return.
If the term deposit was broken in full, or it was business related, deduct the negative interest from the gross interest shown on the IR15 or equivalent statement.
Deduct the allowable negative interest component, using the worksheet below, before entering the gross amount at Question 11 of your return. In all other cases, the negative interest is deductible in a future income year when the term deposit matures.
Interest paid or charged by Inland Revenue
If Inland Revenue paid you interest, include it in Box 11B for the income year the partnership or LTC received the interest.
If the partnership or LTC paid Inland Revenue interest, include it as a deduction in Box 23 of the return for the income year the interest is paid. Read about Expenses.
Interest from overseas
If the partnership or LTC received interest from overseas, convert your overseas interest and tax credits to New Zealand dollars and show the amounts at Question 16. Please read the notes about Overseas income.
Income from financial arrangements
If the partnership or LTC was a party to a financial arrangement, such as government stock, local authority stock, mortgage bonds, futures contracts or deferred property settlements, you may have to calculate the income or expenditure from the financial arrangement using a spreading method, rather than on a cash basis. To work out if you must use a spreading method, please read “Financial arrangements”.
If the financial arrangement matures, is sold, remitted or transferred, you must do a “wash-up” calculation, known as a base price adjustment.
Any RWT will be deducted on a cash basis. Show the RWT deducted and any income from the financial arrangement in Boxes 11A and 11B.
