1. If your customer has not deducted the special VAT invoice, you can directly return the full set of invoices to you, and then you can re-invoice him according to the customer's requirements.
2. In the VAT anti-counterfeiting tax control system, according to the contents of the original tax invoice returned by mistake, fill in an application form for issuing a red-ink invoice, print it out and get it to the competent tax bureau. After examination, the Inland Revenue Department will give you a "Notice of Issuing Red-ink Invoices", and you can come back to issue red-ink invoices according to the contents of the notice.
If the customer has deducted the invoice from his competent tax authority, this time is more troublesome. The deducted tax bill cannot be returned, and you need to write a rejection certificate.
That's all for the invoice refund instructions.
