Summary by Sections Changes in Tax Allocation Calculation Method - The tax allocation calculation method for total and branch institutions has been adjusted, promoting the method used in the final settlement phase to the prepayment phase [3][4]. - Enterprises are now required to allocate the income tax payable up to the current month (or quarter) before deducting the prepayment tax from the total and branch institutions [4].

Case Study of A Company - A Company, registered in Beijing, has branches in Shandong, Shaanxi, and Tianjin, with specific profit figures and tax calculations for each quarter of 2025 [8]. - The allocation ratios for the branches were initially set at 10%, 40%, and 50% for the first quarter, but were later corrected to 30% and 60% for the second quarter [8][10]. - The actual profit amounts for each quarter were reported as follows: Q1: 4 million, Q2: 7 million, Q3: 13 million, Q4: 12 million [8]. Tax Calculation Details - The tax amounts and allocation for each quarter were detailed, showing how the new method impacts the tax payable and the allocation among branches [10][11][12][13]. - For instance, in Q2, the corrected allocation resulted in different tax payable amounts compared to the original calculation method [14].
