01 What is Leqi

Leqi (Natural System) refers to the platform through which the State Taxation Administration provides eligible enterprises, by means of direct connection between the tax system and the enterprise's own information system, with rules-open, standards-unified tax-related services such as fully digitalized e-invoices (hereinafter referred to as "Leqi services").

Leqi for self-use (Natural System Connection for Self-use, "NSCS") means that the Leqi services provided by the enterprise's own information system directly connected to Leqi (hereinafter referred to as the "direct connection platform") apply only to the entity itself and its subordinate entities, and not primarily for obtaining economic benefits. Subordinate entities include group enterprise member entities, equity-controlled entities, etc.

[One-sentence summary]The State Taxation Administration has launched "Leqi Direct Connection Service" for large and medium-sized enterprises; it can only be used for oneself (including branches and subsidiaries) and cannot be used for profit-making purposes.


02 What are Leqi's self-use objects?

The service targets of Leqi involve two categories: direct connection entities and user entities.

The direct connection entity refers to the owner of the direct connection platform, i.e., the main responsible entity, which should be the head office of a head office and branches, the headquarters of a group enterprise, the actual controlling entity with equity control relationships, etc.

A user entity refers to a user that uses relevant Leqi services through the direct connection platform, and should be a head office or branch of a head office-branch structure, a group enterprise headquarters and its subordinate member enterprises, or an affiliated enterprise with an equity control relationship with the direct connection entity, etc.

[One-sentence summary]Leqi's objects are divided into direct connection units and user units. Direct connection units are generally the parent company or head office, and user units are generally subsidiaries or branches. In summary, the direct connection unit applies for Leqi access, and user units can use the direct connection unit's interfaces to connect with the tax bureau.
