Income Tax Calculator for China

TLDR; Tax is calculated based on cumulative income. As your money accumulates throughout the year from your monthly salary, tax is calculated on the total from the beginning of the tax year to the present. Thus, subsequent months from now are likely to have the monthly income taxed at a higher rate.

I used lots of Googling and various resources on the internet to come up with this spreadsheet to help myself understand why I was being taxed the way I was as an expat in China. I think this will provide you value as well.
