The term "current-year earnings do not exceed a given standard" in the first paragraph shall refer to where the current-year earnings of each controlled foreign company are no more than NTD 7 million individually.

When the controlled foreign company indirectly holds the invested enterprises in non-low-tax jurisdictions through multiple layers of invested enterprises in low-tax jurisdictions, and either the controlled foreign company or the intermediary invested enterprise in a low-tax jurisdiction disposes of the equity interest of the invested enterprise of the next layer in a low-tax jurisdiction, the said adjustment amount shall be calculated in accordance with the aforementioned provision.
The calculation of the adjustment amount mentioned in Subparagraph 4 of the preceding paragraph shall be consistent with the following provisions:
1.

If the said foreign currency is not one of the currencies announced by Bank of Taiwan, such conversion should be made using the closing spot buying rate of this foreign currency announced by the major correspondent bank of the controlled foreign company at the end of each month (if such rate is not available, then use the cash buying rate), and convert it to any announced currency of Bank of Taiwan, and then processed according to the aforementioned provision.

A profit-seeking enterprise that directly holds shares or capital of a controlled foreign company, where the controlled foreign company possesses financial instruments measured at fair value through profit or loss (hereinafter referred to as FVPL), may choose to process based on the provisions of this article; the selected method cannot be changed once chosen unless as prescribed in Paragraph 5.
A profit-seeking enterprise shall choose the same calculation method for all its controlled foreign companies in which it holds shares or capital directly; it shall disclose relevant information and attach or prepare documents as prescribed in Article 10.
A profit-seeking enterprise that chooses to comply with the provisions of this article, when calculating the current-year earnings of the controlled foreign company as per Subparagraph 1 of Paragraph 1 of the preceding article, may deduct the amount of FVPL's fair value changes; the said enterprise shall add the adjustment amount for the disposal of FVPL while disposing of FVPL, and add the adjustment amount for the reclassification of FVPL while reclassifying FVPL:
1. The specified "amount of FVPL’s fair value changes" refers to the balance of the gains arising from FVPL's fair value changes minus the losses arising from FVPL's fair value changes.
2. The specified "adjustment amount for the disposal of FVPL" refers to the balance of the FVPL's book value on the disposal date minus the FVPL's original acquisition cost.
3. The specified "adjustment amount for the reclassification of FVPL" refers to the balance of the FVPL’s fair value on the date of reclassification minus the FVPL’s original acquisition cost when the FVPL is reclassified as a financial instrument measured at amortized cost or measured at fair value through other comprehensive income.
The calculation methods specified in the subparagraphs of preceding paragraph shall conform to the following provisions:
1. For the amounts specified in the subparagraphs of preceding paragraph, if the amount obtained is positive, it shall be included as a positive figure in the calculation; if the amount obtained is negative, it shall be included as a negative figure in the calculation.
2. The FVPL's original acquisition cost shall be determined based on its book value at the beginning of the year in which this article is chosen to apply; for a FVPL which is acquired or reclassified from another type of financial instrument during that year, its original acquisition cost shall be determined based on its book value on the purchase date or reclassification date.
3. The FVPL’s original acquisition cost shall be determined based on one of the calculation methods prescribed in Article 46 of the Enforcement Rules of the Income Tax Act; the selected method cannot be changed once chosen until the said FVPL is entirely disposed of.
If a profit-seeking enterprise chooses to calculate the current-year earnings of a controlled foreign company in which it holds shares or capital directly as per the four preceding paragraphs of this article, but fails to provide documents within the deadline as prescribed in Subparagraphs 1 to 4 of Paragraph 1 of Article 10 or fails to provide documents within the deadline as required by the Subparagraph 4 of Paragraph 2 of the same article, or this enterprise does not consistently use the same method for calculating the current-year earnings of the controlled foreign company, then from the year of such non-compliance or non-consistent calculation first occurs, the said enterprise is disqualified from applying the provisions of this article for ten years. Moreover, the net adjustment amount of current-year earnings of the controlled foreign companies as per the two preceding paragraphs shall be accumulated to the closing date of the year in which non-compliance or inconsistency first occurred; such accumulation shall then be included in the current-year earnings of the same year in accordance with the provisions of the preceding article.

To recognize its investment income based on its direct holding ratio and holding period of the shares or capital of a controlled foreign company, a profit-seeking enterprise shall deduct the legal reserve or items of restricted distribution of surplus earnings in accordance with the laws of the country or jurisdiction of the controlled foreign company, as well as the losses of past years assessed by the tax authority, from the current-year earnings of the said controlled foreign company, and such recognized investment income shall be included in its taxable income of the current year.
The holding ratio and holding period of the profit-seeking enterprise mentioned in the preceding paragraph shall be calculated based on the proportion of its holding of the shares or capital of the controlled foreign company relative to the total issued shares or total capital of the controlled foreign company, with the weighted average over the holding period.
From the year a foreign affiliated company qualifies as a controlled foreign company, the profit-seeking enterprise may sequentially deduct assessed losses of previous years from the controlled foreign company’s current-year earnings for up to ten years, starting from the year following the one in which the loss occurred, as prescribed in the first paragraph, provided that, the profit-seeking enterprise has provided documents within the deadline as prescribed in Subparagraphs 1 to 4 of Paragraph 1 of Article 10, and has calculated the losses of the controlled foreign company as prescribed in Article 6 and the preceding article, and has filed them in the required format and such losses have been assessed by the tax authority of the enterprise’s location. For controlled foreign companies exempt from compliance with Paragraph 1 under the criteria of Paragraph 1 of Article 5, the said assessed losses of previous years shall still be deducted from the current-year earnings of the controlled foreign company.
Where a controlled foreign company carries out a capital reduction to compensate the assessed losses mentioned in the preceding paragraph, the amount of loss compensated accordingly shall be sequentially deducted from the assessed losses of previous years.

The difference between the dividends or surplus earnings not included in the taxable income of the distribution year, as mentioned in the preceding paragraph, and the actual amount distributed, which arises from the difference in exchange rates on the distribution date and the rate used to calculate the current-year earnings of the controlled foreign company according to Articles 6 and 7, shall be recognized as the exchange gain or loss of the distribution year.
Where a profit-seeking enterprise has received dividends or surplus earnings from each controlled foreign company, the income tax paid on such dividends or surplus earnings according to the tax laws of the source jurisdiction may be credited against the tax payable of the year in which the investment income is recognized and included in the taxable income, within five years from the day following the filing deadline; any overpaid tax is refundable. Where a profit-seeking enterprise has received dividends or surplus earnings derived from invested enterprises in the Mainland Area, the dividend income tax paid in the Mainland Area, as well as corporate income tax and dividend income tax on the said dividends or surplus earnings paid in any third area, may be credited against the tax payable of the year in which the investment income is recognized and included in the taxable income within the aforementioned time period; any overpaid tax is refundable. The credited amount cannot exceed the increase in tax payable calculated based on the applicable domestic tax rate due to the inclusion of such investment income.
Where a profit-seeking enterprise disposes of the shares or capital of a controlled foreign company, the gain or loss on disposal shall be calculated in accordance with the following provisions:
1. Gain or loss on disposal = Income resulted from the disposal － Original acquisition cost － The balance of the recognized investment income of the controlled foreign company on the disposal date × Disposal ratio.
2. The balance of the recognized investment income of the controlled foreign company on the disposal date, as shown in the preceding subparagraph = The investment income of the controlled foreign company that has been recognized in accordance with Paragraph 1 of the preceding article cumulative to the disposal date － The actual distributed dividends or surplus earnings of previous years excluded from the taxable income of the distribution year in accordance with Paragraph 1 － The deductions of the investment income balance of the controlled foreign company, to be calculated based on the disposal ratios of previous years.

However, if a profit-seeking enterprise can provide any document sufficient to prove the authenticity of the financial statements of the said controlled foreign company, and such document is validated by the tax authority where the profit-seeking enterprise is located, such documents may replace the financial statements that have been audited and attested to by a Certified Public Accountant as prescribed above. If the profit-seeking enterprise is unable to provide such documents before the prescribed deadline, it shall state the reasons and apply for an extension to provide such documents to the tax authority before the filing deadline of the annual income tax return; the maximum extension period is six months and can be granted only once.
