数电发票丨开具发票/红冲后，发票额度如何变化？

Group 1 - The issuance of digital invoices will deduct (occupy) the invoice quota. For example, if a taxpayer has an invoice quota of 500,000 yuan at the beginning of the month and issues a digital invoice with a total amount of 1,000 yuan, the available invoice quota will decrease to 499,115.04 yuan after accounting for tax [2]. - If a red invoice is issued for a previously issued invoice in the same month with the reason "invoice error" or "sales return," the invoice quota will increase by the amount specified on the red invoice. However, if the red invoice is issued for "sales discount," the invoice quota will not change [3][4]. - If the red invoice is issued for an invoice from previous months, the invoice quota will also remain unchanged. For instance, if a taxpayer issues a blue invoice of 1,000 yuan and later issues a red invoice for "sales discount" of 300 yuan, the available invoice quota will still be 499,000 yuan [4][5]. Group 2 - During the VAT declaration period, the available invoice quota before completing the VAT declaration will be the remaining quota from the previous month. Even if a quota adjustment is requested, it will not increase until after the VAT declaration is completed [6]. - For example, if a taxpayer's initial invoice quota is 500,000 yuan and they issue invoices totaling 100,000 yuan in November, their available quota before the December VAT declaration will be 400,000 yuan. After completing the VAT declaration in December, the available quota will be adjusted based on the initial quota and any approved adjustments [7].
