Self-employed people generally pay a fixed tax, and both national tax and local tax are fixed taxes.
There are many standards for the fixed tax of self-employed, not only the business items, but also the area of the store. It is the result of a comprehensive calculation. The specific tax amount depends on the local economic development level, the road section where your store is located, as well as the business scale, business projects and store rent. The situation varies from place to place, so it is difficult to say exactly how much it is.
If the tax department determines that your monthly business volume is less than 5,000 yuan, then you don't have to pay national tax, but only local tax. If it is determined that your monthly business volume is more than 5,000 yuan, then you have to pay both national tax and local tax.
Personally, it is very useful to have a good relationship with the special administrators of the tax bureau who have given you a quota and entertain them well.
