How to distinguish between real invoices and fake invoices?

Invoices are divided into special VAT invoices and ordinary invoices. Firstly, it discusses how to identify the authenticity of special VAT invoices. First, from the appearance, they have the following two characteristics: 1, red fluorescent anti-counterfeiting mark or miniature letter anti-counterfeiting mark. The double solid line under the words "special VAT invoice" in invoice and deduction forms consists of miniature letters. Among them, the upper line is the initials of Chinese characters such as "Special VAT Invoice", and the lower line is the initials of Chinese characters such as "People's Republic of China (PRC) State Taxation Administration of The People's Republic of China Producer". The inner ring of the invoice supervision seal consists of the first letters of several groups of Chinese pinyin letters, such as "People's Republic of China (PRC) State Taxation Administration of The People's Republic of China Supervision", that is, "GJSHWZJJZH". You can see it clearly through a high magnification magnifying glass. 2. The special VAT invoice number is printed with special-shaped number font. Second, the VAT anti-counterfeiting tax control system can play an anti-counterfeiting role. VAT anti-counterfeiting tax control system is a powerful means to strengthen the anti-counterfeiting function of special invoices and avoid collecting false invoices. When an enterprise purchases special invoices from the tax authorities, it needs to hold a tax-controlled IC card issued by the tax authorities. The tax authorities register the starting and ending range of invoices purchased by enterprises on their tax-controlled IC cards through the enterprise issuance subsystem, and at the same time register the flow information of these invoices in the enterprise issuance subsystem. In this way, the tax authorities have mastered the important information about the use of special invoices in invoice issuance. It is convenient to strengthen control and management. In the process of invoicing, the encryption function provided by the anti-counterfeiting invoicing subsystem is used to transfer the main information on the invoice (including invoicing date, invoice code, invoice number, tax registration number of buyers and sellers, amount and tax amount, etc.). ) encrypted to form an anti-counterfeiting electronic password (also called ciphertext) printed on the invoice, and all the information used for encryption is recorded in the black box of the golden tax card. If it is necessary to identify the authenticity of an invoice, the ciphertext on the invoice can be input into the authentication tax filing subsystem through a data scanner or keyboard, and the image can be converted into digital information by using character recognition technology and decrypted to recover seven key parameters, and then compared with the corresponding contents on the invoice. Because the anti-counterfeiting VAT invoice is one ticket and one secret, the comparison result is a real ticket, if not, it is a fake ticket. Let's talk about identifying the authenticity of ordinary invoices: 1. Check online. Now the tax systems in many big cities may have opened online ticket checking systems. The website is also printed on the invoice for enquiry. 2. If your invoice is original, you can only read paper. Real ticket paper is thin, tough, with clear watermark and good lead printing quality. The manufacturer's seal at the top is brightly colored. 3. If you don't bother, call the other tax bureau to ask. The tax number is on the invoice special seal at the bottom of the invoice, and you can find the other tax bureau according to the first six digits of the tax number. If you don't know, you can consult the tax bureau where your unit is located, because they are all online now.
