In the case that the amount of regular income tax for an individual is greater than or equal to the amount of basic tax, the income tax of the current year for the said individual shall be calculated in accordance with the Income Tax Act and other relevant laws; whereas in the case that the amount of regular income tax is less than the amount of basic tax, the amount of income tax payable shall also include the balance between the amount of basic tax and regular income tax, in addition to the amount as calculated in accordance with the Income Tax Act and other relevant laws.

7. The principles underlying the tax credit for overseas tax payment

(1) In the case where income tax has been paid on overseas income in accordance with the laws of the source country of that income, such tax paid may be credited against the basic tax, to the extent that such tax credit shall not exceed the amount of basic tax which is increased in consequence of the inclusion of such income. When a taxpayer applies for tax credit as described in the preceding, he/she shall present the evidence of tax payment issued by the tax office, the overseas tax payment receipt, and relevant documents of the said source country for the same assessment year.

(2) Where an individual receives dividends or surplus earnings from CFCs, the income tax on such dividends or surplus earnings paid in accordance with the tax laws of the source jurisdictions can be credited against the amount of basic tax for the year in which these dividends or surplus earnings are calculated as CFC business income and included in the individual’s basic income.  An individual shall apply for the aforesaid tax credit within five years since the date after the deadline of the filing period of the year in which such CFC business income is included in the individual’s basic income, and any overpaid tax is refundable, to the extent that the tax credit shall not exceed the increase in the basic tax amount due to the inclusion of such CFC business income.
