Annual Bonus Tax Calculation Methods

Method 1: Preferential Calculation (Resident Individuals)

Eligibility Requirements:

1. Resident individual status (183+ days in China)
2. Annual bonus received from single employer
3. Bonus not included in annual comprehensive income
4. Policy valid through December 31, 2027

Calculation Steps:

Step 1: Determine Monthly Bonus Amount

```

Monthly Bonus Amount = Annual Bonus ÷ 12

```

Step 2: Find Applicable Tax Rate and Quick Deduction

1. Use monthly bonus amount to find rate in IIT rate table
2. Identify corresponding quick deduction amount

Step 3: Calculate Tax Liability

```

Tax = Annual Bonus × Applicable Rate - Quick Deduction

```

Example Calculation:

1. Annual bonus: RMB 120,000
2. Monthly bonus amount: RMB 120,000 ÷ 12 = RMB 10,000
3. Applicable rate: 10% (for RMB 10,000 monthly amount)
4. Quick deduction: RMB 210
5. Tax calculation: RMB 120,000 × 10% - RMB 210 = RMB 11,790

Method 2: Separate Calculation (Non-Resident Individuals)

Eligibility Requirements:

1. Non-resident individual status (less than 183 days in China)
2. Annual bonus from China-sourced employment
3. No preferential treatment available

Calculation Steps:

Step 1: Determine Taxable Income

```

Taxable Income = Annual Bonus Amount

```

Step 2: Apply Progressive Rate Table

1. Use full annual bonus amount to find applicable rate
2. Identify corresponding quick deduction

Step 3: Calculate Tax Liability

```

Tax = Annual Bonus × Applicable Rate - Quick Deduction

```

Example Calculation:

1. Annual bonus: RMB 120,000
2. Applicable rate: 10% (for RMB 120,000 annual amount)
3. Quick deduction: RMB 2,520
4. Tax calculation: RMB 120,000 × 10% - RMB 2,520 = RMB 9,480
