Tax on income seems to be a confusing topic for a lot of foreigners in China. In fact, it's pretty straightforward by international standards, though one significant difference from most Western countries is that it is calculated on a monthly basis rather than an annual one.
Foreigners are given a higher tax free allowance (4800RMB per month) than locals (2000 RMB per month), mainly because they don't enjoy the same rights in terms of health and education. So, the first 4800 RMB of a foreigner's monthly income is tax free. The income
above this is taxed according to a progressive scale from 5% to 45%. The bands are as follows:
Income of 500 yuan or less - 5%
That part of income in excess of 500 to 2, 000 yuan - 10%
That part of income in excess of 2,000 to 5, 000 yuan - 15%
That part of income in excess of 5,000 to 20, 000 yuan - 20%
That part of income in excess of 20,000 to 40, 000 yuan - 25%
That part of income in excess of 40,000 to 60, 000 yuan - 30%
That part of income in excess of 60,000 to 80, 000 yuan - 35%
That part of income in excess of 80,000 to 100,000 yuan - 40%
That part of income in excess of 100,000 yuan - 45%

If you earn 6000 yuan a month, it's a little more complicated, but not much. You pay nothing on the first 4800 yuan, 5% on the next 500 yuan, and then 10% on the remaining 700 yuan. So, you pay 25 yuan (5% * 500) plus 70 yuan (10% * 700), which gives a total of 95 yuan.
Taking a salary of 30,000 RMB a month as an example, we would see rates of 5% to 25% applied. The total taxable income is 25,200 (30,000 - 4800). The first 500 is taxed at 5%, the next 1500 is taxed at 10%, and then the following 3000 is taxed at 15%. The next 15,000 is taxed at 20% and the remaining 5,200 is taxed at 25%. That breaks down as:
500*5% = 25
1500*10% = 150
3000*15% = 450
15000*20% = 3000
5200*25% = 1300
This gives a total of 4925 yuan in income tax on a salary of 30,000 yuan a month.
For other incomes it looks like this:
(income per month : tax)
4800 : 0
5000 : 10
5500 : 45
6000 : 95
6500 : 145
7000 : 205
7500 : 280
8000 : 355
9000 : 505
10000 : 665
12000 : 1065
14000 : 1465
16000 : 1865
18000 : 2265
20000 : 2665
25000 : 3675
30000 : 4925
40000 : 7425
50000 : 11235
100000 : 27705
There are some items that are tax deductible, most notably housing and work related transportation, but you need to make sure you have acceptable receipts (not always easy) and that the tax bureau accepts them, something that could vary from region to region. You might also find that your HR department doesn't want the hassle involved when the benefit is yours alone.
