Group 1 - The total invoice limit, also known as the total amount limit for issuing invoices, refers to the maximum amount of invoices that a taxpayer can issue within a natural month, excluding value-added tax (VAT) [3] - The initial invoice limit is the maximum amount of invoices that a taxpayer can issue in a month when first using digital electronic invoices, assigned by the electronic invoice service platform [3] - If a taxpayer fails to declare on time but still has a balance in their invoice limit, they cannot issue invoices until they successfully re-declare [3] Group 2 - During the VAT declaration period, taxpayers can issue invoices according to the available invoice limit from the previous month, provided it does not exceed the total invoice limit for the current month [3] - Taxpayers who declare VAT monthly can use the remaining available invoice limit from the previous month until they complete the declaration for that month [3] - Taxpayers who declare VAT quarterly can use the remaining available invoice limit from the previous month until they complete the declaration for that quarter [3] Group 3 - Taxpayers can issue paper special invoices and general invoices through the electronic invoice service platform, ensuring that the amount of each invoice does not exceed the single highest invoice limit and the available invoice limit for the month [5] - When issuing paper special invoices, general invoices, roll invoices, electronic special invoices, and electronic general invoices, the remaining available limit is deducted based on the number of invoices received, not when issuing [5] Group 4 - The electronic invoice service platform currently does not support issuing digital electronic invoices for specific businesses such as motor vehicles (including second-hand cars) and toll fees, with the announcement of functionality to be made later [6]

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].

Group 1 - The total invoice limit for a taxpayer is the maximum amount of invoices that can be issued within a natural month, excluding value-added tax [2] - Taxpayers can check their invoice limits through the "Invoice Business" module in the electronic tax bureau [3] - To apply for an adjustment of the invoice limit, taxpayers must log into the electronic tax bureau and follow specific steps to submit their application [3][5] Group 2 - The monthly invoice limit can change due to four types of adjustments: initial monthly allocation, temporary adjustments, periodic adjustments, and manual adjustments [5] - Initial monthly allocation is an automatic adjustment made by the system at the beginning of each month based on the previous month's total invoice amount [5][10] - Temporary adjustments occur when a taxpayer's cumulative invoice amount reaches a certain threshold, resulting in an automatic increase in the monthly invoice limit [5][10] - Manual adjustments are made when a taxpayer requests a change due to changes in their actual business situation, subject to verification by the tax authority [6]
