[2] The Enterprise Income Tax Law and its implementation rules also impose a withholding tax at 10%, unless reduced by a tax treaty or agreement, for dividends receivable by non-PRC-resident enterprises from PRC-resident enterprises in respect of earnings accumulated beginning on January 1, 2008. As of August 31, 2022, the Group has recorded RMB 25,000 for dividend withholding tax at rate of 10% related to the distributed earnings of Zhuhai Bright Scholar to its immediate holding company Time Education China Holdings Limited located in Hong Kong. As of August 31, 2023, the Group expects to distribute a portion of the earnings (RMB 202,000) of Zhuhai Bright Scholar to Time Education China Holdings Limited, and hence accrued a withholding tax of RMB 20,200 at rate of 10% at the year end. The remaining undistributed earnings of the Company’s PRC subsidiaries are intended to be permanently reinvested, and accordingly, no deferred tax liabilities have been provided for the PRC dividend withholding taxes that would be payable upon the distribution of those amounts to the Company.
