  • Applicable to cases involving: capital contribution in the form of assets, mergers, consolidations, and conversion of business type.

Here's a quick classification guide for businesses to refer to:

  • State-owned enterprises under the 100% capital structure, upon equitization or merger: are exempt from taxes according to preferential regulations.
  • Private or non-state-owned enterprises: Must pay tax when an increase in tax difference arises.
  • Contributing assets to a joint venture: The difference is still subject to tax.

Conclude

From a legal and practical perspective, it can be affirmed that in most cases, the increase in assets is subject to tax and is included in other income when determining corporate income tax. Only in a few specific cases, such as the restructuring of state-owned enterprises according to an approved plan, may tax exemption be considered.

This is key to ensuring compliance, optimizing tax costs, and ensuring stable long-term operations.
