Coffee shop self-employed people can open special tickets and ordinary tickets. Special VAT invoices can be deducted, but ordinary VAT invoices cannot be deducted. When issuing invoices, special VAT invoices need the buyer's detailed information, while ordinary VAT invoices do not. When used, the special VAT invoice is unlimited, and the service life of the ordinary VAT invoice is 2 months. Only general VAT taxpayers can issue special VAT invoices. As a unit with both general VAT invoices and special VAT invoices, the tax paid by issuing these two invoices is the same.
