For example, a computer vendor issues an invoice to a customer, which means that the vendor has to pay taxes. How does the tax bureau know that the vendor has issued an invoice?

Of course, the tax authorities know that if it is a handwritten ticket, it is usually one copy, and there are several copies. You only have to take one of them. Merchants also need to take the rest to the tax bureau for tax returns, and then they can buy an invoice from the tax bureau. If you want to void the invoice, you must have several copies at the same time to void it, and then return it to the tax bureau. Otherwise, the tax investigation will have serious consequences.

if the invoice is made by machine, it needs to be networked, and it can only be opened by a special computer. When invoicing, a card, similar to a bank card, is needed, and the card can only be invoiced after being inserted into a card reader for verification. As soon as the ticket is issued, you can find your invoice at the tax office. If the machine-printed invoice is invalid, it is necessary to put several copies together, put them into the printer again, and print them invalid. It can also be found in the tax bureau immediately after it is invalidated.

how to tell the authenticity of an invoice (when repairing the machine)?

there is no need to worry about fake invoices when repairing, because the repair station will not verify the authenticity of your invoices. There is no great need to worry about not maintaining it. The crime of making fake invoices is not lighter than that of making counterfeit money. In many cases, some people take invoices to the company for underwriting, and the company's finance department will send the invoices to the tax bureau in order to offset the tax. If the tax bureau finds that they are fake, it will trace them down one-stop, so the risk of making fake invoices is higher than that of making counterfeit banknotes. No one is so stupid to make fake invoices. If someone has the skills to make fake invoices, they might as well make fake tickets, right?

is the effect of machine-printed invoice the same as that of handwritten invoice?

these two invoices are the same, and the taxes to be paid are the same. Handwritten tickets are generally called "ordinary invoices" and machine-made tickets are called "VAT ordinary invoices". The effect of both is the same. Generally speaking, self-employed individuals can open handwritten tickets, and ordinary taxpayers can start to play tickets.

why are there no invoices for goods outside the computer? Can't you just make out an invoice?

machines from other areas are called cross-selling in the IT industry. These machines are cheap because they are sold after washing the tax points in the outer area. If you get the goods from the regular general agent, it is the price including tax. Simply put, if his goods are taken from the general agent, then all his machines are tax-included, so every machine sold should have a ticket to open. All the goods from other areas are sold at duty-paid points, and there is no invoice when the goods are purchased, so there is no ticket for you.

I'll give you a general knowledge of invoices.

according to national laws, all dealers need to issue invoices to customers during the sales process. But sellers are divided into "individuals" and "general taxpayers".

The monthly tax paid by the self-employed is fixed (usually). For example, if the self-employed pays a monthly tax of 11W, he can issue an invoice of 11W, but he can't issue more than 11W. If it exceeds 11W, he has to go through another complicated process with the tax bureau, so I won't say much about this process. It is good to know the general meaning. Such individuals are called fixed taxes.

There is also a self-employed person who can issue invoices indefinitely, but pays taxes according to a certain proportion of the invoiced amount. For example, if he issues an invoice of RMB 111, he needs to pay taxes in 4 yuan, and so on. Different regions pay different taxes, just as a metaphor.

ordinary taxpayers, which are generally corporate. They can't just invoice. If the general taxpayer wants to invoice out, someone must invoice him. Example: Company A has delivered 11 machines with a price of 5111 yuan from the general manager. The general agent issues an invoice to Company A for 5111 laptops each, and this invoice is one. Company A sells 5111 yuan each and issues an invoice to the customer. Then go to the tax bureau to pay taxes, and the tax they need to pay is 17% of the profit. After selling these 11 computers, you need to pay a tax of 171 yuan. If you are a general self-employed, you need to pay a tax of 214 yuan according to the 4% tax. If Company A doesn't have this invoice, he needs to pay 17% of the total sales amount, that is, 8671 yuan tax, which is equivalent to 867 yuan tax for each invoice after 5111 yuan is sold. Therefore, they can't issue invoices at will, and issue as many tickets as they take.

you can rest assured that generally, the invoices we can get will not be fake. If people who are not so stupid make and use fake invoices, the consequences of making fake invoices will be very serious. If I have the technology, I will go to make fake tickets, with high profits and light punishment when I am caught. Making 1 1W invoices only saves 1,711 yuan in tax at most. Besides, companies are afraid to use fake invoices, and they can't make money from them. If this 1W invoice is in the hands of self-employed, it will only save 411 yuan tax, and you will have to take risks. People who are not that stupid. However, the ticket inspection with the same amount of 1W is 1W's profit. No matter how it is calculated, it is a fake ticket.

The repair station doesn't verify the authenticity of the invoice at all, and it's too lazy to read it. The reason is the same as the above. Who is so stupid to use fake invoices? The landlord always asks about fake invoices. Can you make fake invoices? Get a fake invoice or just for warranty? Give up. If you lose the invoice, you can only admit bad luck, or spend money to buy one, find an acquaintance, or go to the computer store and ask if you can spend money to buy an invoice.
