If the year-end bonus you mentioned belongs to the one-off bonus for the whole year, the taxpayer can choose not to incorporate it into the comprehensive income for the whole year and calculate the personal income tax separately.

of course, you can also choose to incorporate the comprehensive income of the whole year (salary income of the current month), and withhold the personal income tax in advance according to the cumulative withholding method, and calculate the personal income tax according to the seven-level excess progressive tax rate of the comprehensive income at the time of final settlement.

for the annual one-time bonus, if the taxpayer chooses not to incorporate the annual comprehensive income (salary income of the current month) and calculate the personal income tax separately, it can be calculated according to the following steps:

Step 1, calculate the converted monthly taxable income. The taxable income of the whole month is the amount obtained by dividing the one-time bonus income of the whole year by 12 months.

the second step is to determine the applicable tax rate. According to the comprehensive income tax rate table after monthly conversion, determine the applicable tax rate and quick deduction.

the third step is to calculate the tax separately. The calculation formula is: tax payable = annual one-time bonus income × applicable tax rate-quick deduction.

suppose that your one-time bonus for the whole year is 1.2 million yuan, and you choose not to incorporate it into the comprehensive income for the whole year and calculate the personal income tax separately, then the steps are as follows:

Step 1, determine the taxable income for the whole month.

the monthly taxable income is 121111÷12=11111 yuan.

the second step is to determine the applicable tax rate.

for the monthly tax rate table, since 11111 is between 3111 yuan and 12111 yuan, the series is 2, the tax rate is 11%, and the quick deduction is 211.

the third step is to calculate the tax payable. The tax payable is 121111×11%-211=11791 yuan.

It should be noted that:

1. In a tax year, this tax calculation method can only be used once for each taxpayer.

2. Whether it is incorporated into the annual comprehensive income is up to the taxpayer to choose. Under normal circumstances, taxpayers should choose the method of paying relatively less taxes throughout the year. Because the introduction of this policy is to reduce the tax burden of taxpayers and relieve the pressure of low-and middle-income groups.

3. The one-time bonus for the whole year is not incorporated into the salary income of the current month, and the policy of separate monthly taxation is implemented, which is now extended to the end of 2123.

4. The annual one-time bonus refers to the one-time bonus paid to employees by withholding agents such as administrative organs, enterprises and institutions according to their annual economic benefits and comprehensive assessment of employees' annual work performance. The above-mentioned one-time bonus also includes year-end salary increase, annual salary and performance salary paid by the unit that implements the annual salary system and performance salary method according to the assessment.

5. All bonuses obtained by employees except the one-time bonus for the whole year, such as semi-annual bonus, quarterly bonus, overtime bonus, advanced bonus, attendance bonus, etc., shall be merged with the salary and salary income of the current month, and personal income tax shall be paid according to the provisions of the tax law.

6. The annual salary and performance salary realized by the unit and individual at the end of the year can be included in the annual one-time bonus and taxed separately.
