IR4 Question 36 Foreign-sourced dividends
Generally, funds would use the default FIF income calculation method (the fair dividend rate) which does not tax dividends separately. However, the foreign tax deducted from the dividend can be claimed as a credit against the tax payable on the calculated FIF income.
A credit for any tax paid by the foreign company (on its earnings) may be allowed in calculating the amount payable by the New Zealand company. Any NRWT deducted from the foreign dividend paid to the New Zealand company may also be allowed as a credit.
