Foreign tax credit
The principal method of avoiding double taxation is the credit method, although the exemption method is still applied in a few older treaties. Foreign tax can be credited against taxes payable in Finland on the same income over the same period on a pro-rata basis. The credit is given for taxes paid to a foreign state and covered by the relevant double tax treaty (DTT). The maximum credit is the lesser of either the amount of the foreign tax or an amount equal to the Finnish tax payable on the income from a foreign state. This maximum is calculated on a source-by-source basis. Unused credit of foreign tax paid may be carried forward for five years on an income basket basis.
