1, see the invoice producer seal. There is an oval red "Invoice Producer Seal" in the center of the invoice. The outer ring line of this chapter is a common thick red line, but the inner ring line is printed by miniature technology and consists of several groups of initials of Chinese pinyin, namely "GJSHWZJJZH". You can see it clearly through a high magnification magnifying glass. At present, fake tickets can't do this.
2. irradiate with ultraviolet light. Real tickets are printed on special paper. Under the irradiation of ultraviolet rays, luminous metal bars will appear on the face of real tickets every once in a while, while fake tickets do not have such luminous metal bars under ultraviolet rays.
3. Check it on the website. Look at the name of the invoice. It says "XX VAT general (or special) invoice" and "XX" is the name of the province. If the invoice name is "General VAT Invoice of Guangxi Zhuang Autonomous Region", you can log on to the website of Guangxi State Taxation Bureau, enter the invoice code and invoice number, and then you can inquire whether there is an invoice with this number. The national tax and local tax departments of all provinces have established websites to provide invoice inquiry functions. As long as it is a genuine ticket, any VAT invoice and business tax invoice can be found on the website.
Inquiring the invoice through the website can not only identify the authenticity of the drawer, but also confirm whether the ticket is "true or false". If the invoice is true, the drawer written on the ticket face is Company A, but the website query results show that the invoice was purchased by Company B, indicating that although the invoice itself is true, the contents issued are false, which is an illegal invoice and cannot be used for financial reimbursement.
4. Call and ask. You can call the tax service hotline 12366 and follow the prompts to make an inquiry.
5. Inquiries from the Inland Revenue Department. You can take the invoice to the tax authorities and ask the staff to help identify the authenticity.
