Kailing Technology individual reverse invoicing identity verification API: one-click penetrating queries for nationwide enterprise legal representatives, directors and senior executives, and sole proprietors, with non-compliant identities blocked in seconds

At a time when the circular economy is flourishing, the "reverse invoicing" policy is opening up a key link in input VAT deduction for industries such as resource recycling and online freight. However, behind the policy dividend, an invisible compliance pitfall is making countless enterprises pay a heavy price—Is the person you issued the invoice to really an ordinary natural person?

First look at a real case. A chip recycling enterprise, Company M, submitted a reverse invoicing application to the tax authority. The materials were complete and the process standardized, with no apparent flaws on the surface. However, through big data cross-comparison, tax officials discovered several chilling doubts: the bank cards of three individual sellers came from the same rural commercial bank and the same account-opening branch, highly suspected to be company payroll cards; further verification found that all three worked at an upstream enterprise of Company M, and the legal representative of Company M was also a shareholder of that upstream enterprise. Ultimately, Company M's reverse invoicing application was rejected, and it faced significant tax compliance risk.

This is not an isolated case. With the full implementation of China Golden Tax Phase IV, tax authorities are using big data platforms to implement "three-dimensional tracking" of reverse invoicing, integrating information such as natural persons' contact details, APP real-name registration, and invested market entities for risk screening. In 2025, cases pushed for risk and subject to tax repayment and fines due to non-compliant reverse invoicing surged by 37% year on year. The inspection department of the State Taxation Administration has also clearly designated industries such as online freight platforms as key regulatory directions.

In this elimination round of tax compliance, Kailing Technology has launched a product that directly addresses the pain points—Natural person reverse invoicing identity verification interface, build an automated compliance bridge between the national business registration database and the public security identity authentication system, so that non-compliant counterparties are "blocked in seconds" before invoicing.

Why is the identity red line so important?

According to Announcement No. 5 of 2024 of the State Taxation Administration, the invoice recipient of reverse invoicing must be a genuine "individual seller of scrapped products." The policy clearly stipulates: scrapped products provided by individuals in the capacity of employees hired by recycling enterprises may not be reverse invoiced; those who have established individual businesses or other business entities engaged in recycling business may no longer reverse invoice as individuals.

In other words, if the counterparty is the legal representative, incumbent director, or supervisor of a company, or the operator of a registered individual industrial and commercial household, their identity itself fundamentally conflicts with the positioning of an "ordinary individual seller." Once an enterprise incorrectly issues an invoice to such an entity, the reverse-issued invoice will be deemed invalid, and the enterprise must transfer out input tax, pay additional taxes, and incur late fees. In serious cases, it may be characterized as false invoicing, facing administrative penalties or even criminal liability.

However, the real dilemma enterprises face is: identity information is scattered across industrial and commercial registration systems throughout the country, and one person may simultaneously hold different roles in multiple provinces. A resource recycling enterprise deals with dozens or hundreds of individual sellers every day, and checking each one through the National Enterprise Credit Information Publicity System is neither realistic nor possible to exhaustively complete.

Millisecond-level penetration leaves "identity disguise" nowhere to hide.

The design logic of Kailing Technology's individual identity verification API is very clear:Three automated verifications are completed before invoicing, with non-compliant items intercepted in seconds and compliant ones passed without friction.

The first barrier: public security identity authenticity verification. The interface calls the Ministry of Public Security's authoritative identity authentication channel, compares whether the name and ID number are consistent, and at the same time confirms through liveness detection that the operator is the person themselves, eliminating from the source the fraudulent invoicing method of "using another person's identity to issue invoices."

The second one: Penetrating query of business registration roles. This is the interface's most core capability. Based on the ID number, the system automatically queries all of that individual's employment records in the National Enterprise Credit Information Publicity System — unlimited by province, number of enterprises, or employment status — covering in one pass legal representatives, shareholders (including shareholding ratios), directors, supervisors, senior managers (general managers, financial officers, etc.), and individual business operators. Whether the person registered a company in Xinjiang or registered an individual business in Hainan, all information is captured and presented in a structured format.

The third step: Compliance determination and automatic interception. The system divides verification results into three types of handling: those confirmed as ordinary natural persons without non-compliant roles are automatically released; those with the identity of enterprise legal representative, director, supervisor, senior executive or sole proprietor are automatically intercepted by the system and the specific reason is returned; those with historical roles in deregistered enterprises are given a warning prompt, and the enterprise makes its own judgment. The entire verification process usually responds within 300 milliseconds, completely imperceptible to natural persons, while serving as a solid compliance barrier for enterprises.

More than identity verification: building a full-chain compliance evidence chain.

Identity compliance is the first gate of reverse invoicing, but not the whole story. Kailing Technology's solution simultaneously connects the two major links of quota validation and "five-flow integration."

In terms of quota, the interface directly connects to the tax bureau to conduct real-time online verification of the individual's RMB 5 million invoicing quota. The system automatically tracks the cumulative invoicing data of each individual within 12 consecutive months, with cross-enterprise quotas all included in the monitoring scope. It automatically warns when approaching the RMB 5 million upper limit and directly blocks when exceeded. It is worth noting that this quota is a "cross-enterprise cumulative" amount—sales amounts from multiple enterprises issuing invoices to the same individual must be combined for calculation, which is nearly impossible to accurately control with manual ledgers alone.

At the same time, the solution supports the automated linkage of the "five flows in one" of contract flow, business flow, logistics flow, capital flow, and invoice flow, forming a complete closed loop of the evidence chain for every transaction. Combined with Beidou/GPS intelligent logistics trajectory tracking, the system builds a complete compliance defense line for enterprises from the transaction source to the invoice endpoint.

Policies Continue to Deepen, Compliance Ushers in a Critical Window Period

The policy implementation of reverse invoicing is accelerating. Starting in January 2026, 10 provinces and municipalities including Tianjin, Shandong, and Anhui, in accordance with relevant notices from the State Taxation Administration, successively launched "reverse invoicing" pilots, allowing online freight platform enterprises to issue special VAT invoices in reverse on behalf of individual drivers who have not completed tax registration. In February of the same year, the State Taxation Administration further clarified that for six specific situations, including individuals selling scrap products through "reverse invoicing," the threshold standard of RMB 1,000 for per-transaction taxation no longer applies; instead, the threshold standard of RMB 100,000 in monthly sales for periodic taxation applies directly. The continuous refinement of policy means that the scope of application for reverse invoicing is expanding, while the accompanying regulatory granularity is also tightening.

Kailing Technology's identity verification interface precisely addresses the core pain point in this compliance wave. It is not a post-event remediation tool, but moves the risk interception node to the very front of the invoicing process, using technical means to resolve compliance challenges that manual efforts cannot exhaust. In an era of increasingly precise tax audits and rising enterprise tax-related risks, this "second-level blocking" safety lock is becoming an indispensable compliance infrastructure for enterprises' reverse invoicing business.
