Common Questions
When issuing a red-letter fully digitalized e-invoice, what are the reversal rules between different invoice types?
Fully digitalized e-invoices can issue red-letter reversals for fully digitalized e-invoices, fully digitalized paper invoices, and tax control invoices; fully digitalized paper invoices can only issue red-letter reversals for themselves and tax control invoices, and cannot issue red-letter reversals for fully digitalized e-invoices; tax control invoices can only issue red-letter reversals for tax control invoices, and cannot issue red-letter reversals for fully digitalized e-invoices or fully digitalized paper invoices.
After issuing a red-letter fully digitalized e-invoice, how will the credit limit change?
If a blue-letter fully digitalized e-invoice is issued in the current month and a red-letter invoice is issued in the same month, the electronic invoice service platform simultaneously increases the remaining available quota for the current month; if issued across months, the remaining available quota for the current month is not increased. The amount that can be issued for a red-letter fully digitalized e-invoice must be within the user's current blue-letter available credit quota.
Do red-letter fully digitalized e-invoices support partial reversal? Under what circumstances must a full reversal be made?
When the purchaser has not made a purpose confirmation, the seller-initiated red-letter reversal only supports full reversal; selecting "incorrect invoicing" as the reason only supports full reversal; selecting "sales return", "service suspension", or "sales discount" supports partial reversal. When a blue-letter invoice has an agricultural product additional deduction tag or a differential taxation tag, full reversal is mandatory.
What time limits and cancellation rules apply after a red-letter confirmation form is initiated?
After either party initiates a red-letter confirmation form, the other party must confirm within 72 hours, otherwise it is automatically voided. If the seller initiates a red-letter confirmation form that does not require confirmation, it can be withdrawn before invoicing; if the other party has confirmed, the initiating party cannot revoke it, but the confirming party may revoke it after confirmation and before invoicing. A confirmed form that has been invoiced cannot be revoked.
After a red-letter fully digitalized e-invoice is issued, what should be done if the original blue-letter invoice was used for export tax rebates?
According to an announcement of the Shanghai Municipal Tax Service of the State Taxation Administration, if a fully digitalized e-invoice or paper invoice issued through the electronic invoice service platform has been used to apply for export tax refund or tax refund on behalf, issuing a red-letter fully digitalized e-invoice is temporarily not allowed.
