Working in Japan and returning to China after paying social security can't be refunded.

But the annuity can be refunded.

As long as you work in a regular company, the tax is the same whether you have a supporter or not.

District/citizen tax, unemployment insurance, annuity, social insurance and tax source tax are all indispensable.

If your company joins 40 1K, there will be 40 1K insurance.

But the exact amount of money you pay varies according to the area where you live, your income and the insurance company you join.

Take me personally for example. My monthly salary is 30W, and I have to pay about 5W for all kinds of miscellaneous taxes.

Those assigned to China should be regarded as working in Japan, so social security and annuity should be given to Japan. Because, in this case, although you are a foreigner, you are counted as a Japanese employee, and the company must pay you according to the Japanese price standard, otherwise it will violate the Lao Ji Law.

If you are a full member, social security and annuity are generally paid through the company (because the company also has to pay part of it to employees). In this case, lz needs to consult the management department of the company specifically.

If you pay by individuals instead of companies, you can avoid annuities and social security in both Japan and China. However, if you want to settle in Japan, you'd better be honest.
