Registration and License Tax | A Supreme Court Judgment Finding That a Capital Increase by Debt-to-Equity Conversion Constitutes a Taxable Object

The registration and license tax is a local tax imposed when a company or an individual registers or records a change in rights. The issue in this judgment was whether a taxable object arises in the case of a debt-to-equity conversion and new shares that were immediately retired. (Supreme Court, Decision of September 4, 2025, 2025 Du 33456)

1. A Case in Which Whether the Registration and License Tax Applied Was at Issue

A case in which whether a taxable object for registration and license tax existed was at issue

This is a case in which whether a taxable object for the registration and license tax existed was at issue.


The outline of the case is as follows.

The Rehabilitation Proceedings and the Course of the Debt-to-Equity Conversion

The plaintiff company had rehabilitation proceedings commenced in 2018 and obtained approval of its rehabilitation plan in 2019.

Thereafter, it converted approximately 4.8 billion won of debt into 968,413 shares, but all of the newly issued shares were retired without consideration the following day.

However, the registration of the capital increase was completed in April 2019 upon the court's commission, and the rehabilitation proceedings were closed in September of the same year.

The Tax Disposition

The head of Gangnam-gu Office (the defendant) treated this debt-to-equity conversion registration as a taxable object in 2023 and imposed registration and license tax of approximately 58.1 million won and local education tax of approximately 11.62 million won.

The plaintiff stock company sought revocation of the disposition.

The Lower Court's Determination

With respect to the registration and license tax, the lower court held that the registration of the capital increase resulting from the debt-to-equity conversion was a taxable object as provided in the Local Tax Act amended on December 29, 2015.


It found that the exemption provision under the former Debtor Rehabilitation and Bankruptcy Act could not serve as a basis for application, and that, because the new shares were all retired immediately after issuance, there was no substantive change in the plaintiff's property rights.

Accordingly, it concluded that the imposition of registration and license tax was unlawful as contrary to the principle of substance-over-form taxation (Article 17, Paragraph 2 of the Framework Act on Local Taxes).

Registration and License Tax Provision under the Former Debtor Rehabilitation and Bankruptcy Act

It provides that no registration and license tax is imposed on registration or recording under Article 25, Paragraph 1 of the former Debtor Rehabilitation and Bankruptcy Act.

The addenda to the Local Tax Act set the enforcement date of the statute as January 1, 2024, and expressly provided that the amended provisions also apply where, as of that enforcement date, rehabilitation proceedings or simplified rehabilitation proceedings are pending, or a rehabilitation plan or simplified rehabilitation plan is being carried out, under the former Debtor Rehabilitation and Bankruptcy Act.

However, when the former Debtor Rehabilitation and Bankruptcy Act was amended on February 13, 2024, Article 25, Paragraph 4 concerning the exemption from registration and license tax was deleted.

→ This reflects the purpose of the Restriction of Special Local Taxation Act, which precludes establishing local tax exceptions to general taxation prescribed under the Local Tax Act except in accordance with the Restriction of Special Local Taxation Act, the Framework Act on Local Taxes, the Local Tax Collection Act, the Local Tax Act, the Restriction of Special Taxation Act, and treaties.

→ It is a measure to regulate the registration and license tax assessment system uniformly under the local tax statutes.

2. The Supreme Court's Determination on Whether the Registration and License Tax Applied

The Supreme Court's determination, however, was different.

The Supreme Court's determination with respect to whether the registration and license tax applied is as follows.

1) The Statute Applicable to the Registration and License Tax

Where statutes conflict, they must be interpreted in accordance with the principle that the later statute and the special statute prevail.

The Court held that, with respect to the registration of a capital increase related to rehabilitation, it accords with the legislative intent that the proviso of the Local Tax Act amended in 2015, rather than the former Debtor Rehabilitation and Bankruptcy Act, applies preferentially.

The Court held that, because this case involved an issuance of new shares without new payment (Article 265), the exemption provision did not apply.

2) Retirement Without Consideration and Taxability

The taxable object of the registration and license tax is ‘the fact of registration or recording itself.’

Therefore, even if the new shares are subsequently retired without consideration, the requirements for taxation are satisfied so long as the registration has already been made.

Tax statutes must, as a rule, be interpreted strictly according to their text, and exemption provisions in particular must be applied even more strictly.

Accordingly, the Supreme Court held that the lower court had erred by misapprehending the legal principles when it revoked the tax disposition on the ground that “there was no substantive change in property rights,” and it reversed the lower judgment and remanded the case for further proceedings.

3. What Is Daeryun's Strategy Regarding the Registration and License Tax Taxable Object?

The registration and license tax takes as its taxable object the fact of registration itself, not the substance of the right.

Therefore, even if the new shares are subsequently retired, this does not affect a tax liability that has already arisen.

In rehabilitation proceedings, the issuance of new shares is divided into two types, which may be summarized as follows.

-Article 266 of the former Debtor Rehabilitation and Bankruptcy Act: where there is new payment or a contribution in kind → exemption may apply
-Article 265 of the former Debtor Rehabilitation and Bankruptcy Act: where there is no new payment → not subject to exemption

This case fell under the Article 265 type, so the exemption did not apply.

The Significance of the Statutory Amendments
-2015 amendment: excluded debt-to-equity conversion and capital increase registrations from non-taxation (shifting them to taxation)
-2023 amendment (enforced in 2024): adjusted them back to exemption, but applied only to rehabilitation proceedings pending at the time of enforcement
-2024 amendment: deleted the exemption provision of the Debtor Rehabilitation and Bankruptcy Act, regulating the matter solely under the Local Tax Act

In other words, the registration at the time of the case (2019) became a taxable object under the 2015 amended provisions.

When structuring a debt-to-equity conversion in rehabilitation proceedings, one must consider that a registration and license tax burden may arise at the registration stage.

This judgment also made clear that the argument that ‘there is no substantive change in assets’ is not accepted as a line of defense.
