If you pay investment income, you can file withholding summary returns in myIR using an online form.
This option suits payers who:
- do not file often
- can enter information manually
- have no more than 2,000 payees (line items).
Gather your information
You’ll need records that contain the following information for everyone you have paid income to for the month.
For example, with RWT on interest you’ll need details of:
- gross interest paid
- deducted RWT
- RWT rate
- information about joint account holders if this applies to you
- your bank details.
Access your withholding tax account in myIR
For example, click the ‘RWT on interest’ hyperlink on the account tile.
Select your return for the relevant period
Select the 'Periods' tab and select 'File return' for the relevant period.
Fill in the form
Select ‘Enter online’, then select ‘Add a new line item’ for each person you’ve paid.
For each line item you need to do the following:
- Fill in the recipient’s details as specified on the screen.
- Select “Add an income” and complete the Gross interest, RWT deducted and RWT rate fields.
- If the account is a joint account, select “Add a joint account holder” and complete the details for the second account holder. You will need to repeat this if the account has more than two joint holders.
You’ll need to fill in this information every time you file using the myIR online form, even if the details are the same as a previous return. The form is not pre-populated.
Once you've finished adding line items, review your entries and complete the declaration.
Make your payment
You can choose to pay by direct debit now. If so, enter your bank details and select 'Payment confirmation'.
You can also choose to pay later.
Only select ‘final return’ if you are no longer going to be paying investment income.
Submit your online return
A confirmation page will show once the return has been submitted.
