In the case that the taxpayer, his/her spouse, and/or dependents, who shall file a joint consolidated income tax return in accordance with the Income Tax Act, have an amount of income which includes any one or more of the conditions applying under the Income Basic Tax Act, he/she shall include any such amount in the return for the calculation of income basic tax.

3. The kinds of items included in the calculation of the amount of basic income

The following items are included in the calculation of the amount of basic income:

(1) Net taxable income:

The net taxable income is calculated in accordance with the Income Tax Act (please refer to the individual income tax return).

(2) Overseas income:

Income, which is derived from sources outside the R.O.C. and is excluded from gross consolidated income, as well as income which is exempted in accordance with Paragraph 1, Article 28 of the Act Governing Relations with Hong Kong and Macau. However, if the aggregate of the two aforementioned sources of income in a filing unit is less than NT$1,000,000, it may be excluded from the basic income; otherwise, it shall be filed in the full amount of the aggregate income mentioned above.

(3) Life and annuity insurance payments:

Insurance payments received by the beneficiary, on condition that the beneficiary and the proposer are not the same person and that the life insurance policy and annuities are contracted after this Act came into force. However, in the case of payment made upon the death of the insured person, the part of which aggregate of payments made in a filing unit is equal to or less than NT$33,300,000 may be excluded from the basic income in a calendar year.

(4) Income derived from transactions of securities:

1. Share certificates, certificates of entitlement to new shares, stock share payment certificates and documents of title to any of the securities issued or placed privately by a company that is not listed in a stock exchange or traded in the over-the-counter market. 
2. Beneficiary certificates of privately-placed securities investment trust funds

(5) Non-cash donations or contributions:

The amount of non-cash donations or contributions deducted from the gross consolidated income of the individual income tax return.

(6) Total amount of dividends and earnings:

A taxpayer chooses to compute the tax on the total amount of dividends and earnings
separately from his/her gross income with the single tax rate.

4. The way in which the amount of basic tax is computed

For filing an income basic tax return, subtract NT$6,700,000 from the amount of basic income, then multiply the remainder by 20% to produce the amount of basic tax.

5. The way in which the amount of regular income tax is computed

The amount of regular income tax = tax payable of the individual income tax return - investment tax credit for the tax payable. If a taxpayer chooses to compute the tax payable on the total amount of dividends and earnings separately from his/her gross income with the single tax rate, such tax payable shall be aggregated into regular income tax.

6. The principles underlying the income basic tax

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 principle underlying the tax credit for overseas tax payment

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.

8. The filing procedure

Please attach the individual income basic tax return to the individual income tax return.
