China Individual Income Tax Calculator (Estimate)
For mainland China resident employees paid monthly wages. Enter your monthly values in RMB.
How this China tax calculator works
This calculator estimates individual income tax (IIT) for salary income in mainland China using the current progressive tax system for resident taxpayers. It annualizes your monthly salary, applies deductions, calculates annual tax with the official brackets and quick deductions, then converts the result back to a monthly estimate.
It is designed for quick planning: job offer comparison, salary negotiation, and monthly cash flow forecasting.
China salary tax formula (simplified)
Step 1: Determine annual taxable income
Annual taxable income is estimated as:
- Annual gross salary
- minus annual employee social insurance and housing fund
- minus annual special additional deductions
- minus annual basic deduction (usually 60,000 RMB per year)
Step 2: Apply progressive annual tax rates
| Annual taxable income (RMB) | Rate | Quick deduction (RMB) |
|---|---|---|
| 0 – 36,000 | 3% | 0 |
| 36,000 – 144,000 | 10% | 2,520 |
| 144,000 – 300,000 | 20% | 16,920 |
| 300,000 – 420,000 | 25% | 31,920 |
| 420,000 – 660,000 | 30% | 52,920 |
| 660,000 – 960,000 | 35% | 85,920 |
| Over 960,000 | 45% | 181,920 |
Step 3: Convert annual tax to monthly estimate
The tool divides annual tax by 12 to estimate monthly withholding under a stable salary scenario. Real payroll may vary slightly month to month because many employers use cumulative withholding calculations.
What deductions matter most
For many employees, these deductions have the largest impact:
- Social insurance and housing fund: Employee portion reduces taxable income.
- Special additional deductions: Common categories include children’s education, continuing education, housing rent, housing loan interest, elder care, and infant care.
- Basic deduction: Usually fixed at 5,000 RMB per month.
Example scenario
Suppose your gross monthly salary is 20,000 RMB, your employee social and housing contributions are 2,500 RMB/month, and your special additional deductions total 1,000 RMB/month.
- Annual gross: 240,000 RMB
- Annual social/housing: 30,000 RMB
- Annual special additional deductions: 12,000 RMB
- Annual basic deduction: 60,000 RMB
- Estimated annual taxable income: 138,000 RMB
That falls in the 10% bracket, so annual tax is approximately 138,000 × 10% − 2,520 = 11,280 RMB, or about 940 RMB per month.
Common mistakes people make
- Entering employer contributions instead of employee contributions.
- Forgetting to claim special additional deductions.
- Assuming yearly bonus and salary are always taxed identically.
- Using old tax brackets from pre-reform years.
- Ignoring city-level social insurance base changes.
Final tips
Use this China tax calculator as a planning tool, not as an official filing engine. Keep your payroll records, deduction declarations, and city contribution notices updated. For major decisions (expat arrangements, equity compensation, large bonuses, multi-city work, or year-end true-up), get tailored professional advice.
