Resident Withholding Tax is tax deducted on the payment of dividends and interest.
The tax is deducted on the payment date and not the date the interest was earned.
If the recipient of interest has a certificate of exemption, then no withholding tax is deducted.
The withholding tax required to be deducted on the payment of dividends to New Zealand resident shareholders is 33%, less any imputation credits attached to the dividends.
The withholding tax required to be deducted from interest is based on the rate chosen by the recipient, on the basis that the recipient has provided an IRD number.
