As far as I know, the total daily working price of 18 fixed economic visa is taxable. According to relevant policies and regulations, quota economic visa activities belong to one of the economic forms of foreign labor cooperation, and visa holders need to pay corresponding taxes according to law for their remuneration for providing labor services abroad.

The specific tax amount will be calculated according to the provisions of the tax law and the income of visa holders. Generally speaking, individual income tax will be taxed according to the proportion of taxable income. In our country, individual income tax laws stipulate different tax rates and tax items, and the tax rates will be different according to different income levels.

However, the specific tax rate and tax declaration procedures may be different due to different national and regional laws and regulations. It is recommended that you consult the official documents of local tax authorities or consult relevant professionals to obtain accurate tax requirements and obligations.
