Cumulative withholding method
The normal basic deduction is RMB5,000 per employment month with the employer. Special current rules allow the full RMB60,000 annual deduction from January for qualifying employees whose prior full-year wages at the same employer did not exceed RMB60,000, and a separate first-income-in-the-year method can use calendar months elapsed. The cumulative taxable salary uses the 3%–45% seven-bracket withholding table, then subtracts tax already withheld to determine the current month's withholding.
