China offers various tax benefits for expats working in the country, including exemptions of personal income tax on certain subsidies, such as the subsidies for their housing, children's education, and language training.

Here are the key categories of subsidies that qualify for such benefits in China:

1. Foreign individuals who receive reasonable housing subsidies, meal allowances, and laundry fees in non-cash or reimbursement forms are eligible for personal income tax exemptions. Taxpayers must provide valid documentation for these subsidies to the tax authority for approval.

2. Foreigners who receive relocation income in reimbursement form due to their employment or departure from China are exempt from personal income tax for a reasonable portion. 

Monthly or periodic payments made by foreign-invested enterprises, foreign companies, or foreign organizations in China to their foreign employees in the name of relocation must be included in the taxable income for salary and wages.

3. Foreigners who receive domestic or outbound business travel allowances based on reasonable standards are exempt from personal income tax. 

4. Foreigners who receive home visiting subsidies are exempt from personal income tax for the actual expenses related to personal visits.
