Detailed Explanation of Personal Income Tax Calculation Formula

The calculation of personal income tax usually adopts the cumulative withholding method. For monthly salary and wages, the basic calculation formula is as follows:

• Taxable Income = Cumulative Income - Cumulative Tax-exempt Income - Cumulative Deductions - Cumulative Special Deductions - Cumulative Special Additional Deductions - Cumulative Other Deductions Determined by Law
• Where:
• Cumulative Income: Refers to the total salary and wage income obtained by the taxpayer up to the current month.
• Cumulative Deductions: Calculated cumulatively at a standard of 5000 yuan per month, i.e., cumulative deductions for the current month = number of months in the current month × 5000 yuan.
• Cumulative Special Deductions: Refers to personal contributions to basic endowment insurance, basic medical insurance, unemployment insurance, housing provident fund, etc.
• Cumulative Special Additional Deductions: Refers to the sum of six additional deductions: children's education, continuing education, serious illness medical expenses, housing loan interest, housing rent, and supporting the elderly.
• Tax Payable = (Taxable Income × Applicable Tax Rate) - Quick Deduction

This tool automatically calculates in the background according to the above formula and the current tax rate table, ensuring the accuracy of the results.
