Value-added tax is generated in every sale, so it is paid to the manufacturer by the merchant when buying the goods, and you pay it to the merchant when buying.

3. As above, both merchants and manufacturers have to pay taxes to the tax bureau, so the merchants have already paid taxes to the manufacturers. If they need an invoice when they sell it to you, they have to go to the tax bureau to pay again. If you don't want it, they won't pay by making an account. Generally, small businesses pay a fixed tax to the tax authorities every month, no matter how much they sell, so they don't want to give you a ticket.

4. The air ticket is 17%, and the value-added tax rate of ordinary air ticket business is 4%, so when you want to fly an air ticket, it must be more expensive.

The general price includes tax, so don't consider it.

Example: the factory sells to the merchants, 4000+4000*0. 17=4680.

The merchant sells you a ticket: 5000+5000*0. 17=5850.

Ordinary ticket 5000+5000*0.04=5200

No charge of 5000 yuan (general business is fixed tax, regardless of sales)
