On July 25, 2024, the Ministry of Economy and Finance released the 2024 proposed tax law amendment proposals (“Proposals”). The finalization of the Proposals will be subject to further deliberation and approval by the National Assembly. If approved, the Proposals will be implemented from January 1, 2025 unless otherwise specified.

Some of the key Proposals include the following.

To enhance the international competitiveness of the shipping industry, the special corporate income tax regime for shipping enterprises (tonnage tax) will be extended by 5 years, until December 31, 2029.

In addition, effective for 3 years starting from January 1, 2025, different rates will apply to so-called “standard ships” (i.e., ships owned by a shipping enterprise, or used by a shipping enterprise under a bareboat charter), as opposed to “non-standard ships”. Non-standard ships will be subject to a 30% increased rate for the operating day profit per ton.

New tax incentives will be introduced to promote shareholder returns. These incentives aim to align the interests of management with those of investors, thereby enhancing shareholder returns, increasing capital inflows, and boosting stock values, and to address the so-called “Korea Discount” issue. There is a sunset provision, with the incentives effective till December 31, 2027 (3-year period):

Under the Proposals, when a KOSPI- or KOSDAQ-listed company: (i) discloses a “Corporate Value Enhancement Plan”; and (ii) increases its shareholder return amounts compared to the previous year and by more than 5% compared to the average of the previous three years, there will be a corporate income tax credit equal to the increase in shareholder returns exceeding 5%.

Effective January 1, 2025 – December 31, 2028, which is one year longer than ① above, considering the timing of dividend payments, when a KOSPI- or KOSDAQ-listed company that increases shareholder returns pays dividends, the dividend income received by individual shareholders will be subject to separate, lower tax.

In order to encourage indirect real estate investments, valuation gains arising from real estate or other assets held by a Korean real estate investment company will be excluded from the company’s distributable profits.

Under the Proposals, the top IGT rates will be reduced from 50% to 40%. Additionally, the threshold for the lowest 10% rate bracket will be increased from KRW 100 million to KRW 200 million.

Furthermore, the exemption amount for inheritance tax per child will be increased from KRW 50 million to KRW 500 million.

To support business succession, the currently law adding a 20% premium to the valuation of shares held by the largest shareholder and related parties, for IGT purposes will be abolished.

Currently, interest expense paid by both financial and general holding companies on amounts borrowed from foreign related parties is fully deductible (i.e., exempt from the 30% interest deduction limitation rule).

Under the Proposals, interest payments by general holding companies (i.e. those not engaged in financial or insurance business) will no longer be exempt from the thin cap rule capping the net interest deduction at 30% of adjusted income (i.e., EBITDA).

Effective from January 1, 2026, Korean tax residency for individuals will include not only those who reside in Korea for more than 183 days during a calendar year (as is currently the case), but also those who have resided in Korea continuously for more than 183 consecutive days over two calendar years.

Effective from January 1, 2027, as an anti-tax avoidance measure, the automatic financial information exchange system will be expanded to include data on “crypto-assets”. The term "crypto asset" refers to digital representation of value that relies on a cryptographically secured distributed ledger or similar technology to validate and secure transactions.

The requirement for the exchange and submission of crypto-asset information will be applicable from January 1, 2027. Due diligence procedures will be applicable from January 1, 2026.

Currently, when non-resident individuals and foreign companies invest in Korean government bonds (as well as Monetary Stabilization Bonds) through a private OIV, it is necessary for each of these investors separately to submit a tax residence certificate and a tax exemption application to claim tax exemption/exemption from withholding tax on interest and capital gains derived from government bonds. By contrast, a public OIV can apply for the exemption application as the deemed beneficial owner, without needing to disclose the underlying investors.

Under the Proposals, the private OIV itself will be deemed the beneficial owner of interest income and capital gains from government bonds, without the need to identify the underlying investors (as is already the case for public OIVs).

But if any of the underlying investors are Korean residents or domestic companies, they will be permitted to report and pay taxes directly without incurring withholding taxes.

Under the Proposals, non-resident individuals and foreign companies will also be able to apply for refund of withholding tax on interest and capital gains derived from government bonds directly, not only through withholding agents (as is currently the case).

Under the Proposals, taxpayers excluded from FFA reporting obligations will also include: (i) persons who are recognized as residents of another Contracting State pursuant to a tax treaty due to a lawsuit or mutual agreement procedure; and (ii) residents and domestic companies whose FFAs are verified through foreign trust details submitted to the tax authority.

When a controlled company benefits from a transaction with a related person of its controlling shareholder, it is deemed that the controlling shareholder has received a donation from the related person, and gift tax is imposed on the controlling shareholder based on the deemed donation. Under the Proposal, this deemed donation will now also include distributions of profits through capital transactions.

Currently, when Korean-sourced personal service income is paid to non-resident individuals and foreign companies without a Korean PE, the recipients can receive a withholding tax exemption under a relevant tax treaty without needing to submit any application.

Effective from January 1, 2026, it will become mandatory for such recipients to make an application for exemption/non-taxation, accompanied by supporting documentation.

Currently, under Korean transfer pricing regulations, taxpayers can claim a tax refund by filing an amended tax return, to adjust a transaction price to the arm’s length price.

Under the Proposals, taxpayers will now need to submit proof of the arm’s length pricing along with the amended tax return and declaration form for transfer price adjustment. Additionally, the deadline for the Korean tax authority to decide whether to accept or reject such an amended tax return has been extended from 2 months to 6 months after the filing date.

To better align the domestic Global Minimum Tax (GloBE) rules with the OECD’s Model Rules and Administrative Guidance, the Proposal clarifies definitions of key terms such as “Group”, “Constituent Entity, “Permanent Establishment”, and “Partially Owned Intermediate Parent”. The proposal also adds new provisions, including exceptions to the De Minimis rules, safe harbor provisions, allocation methods for the top-up tax, and an extension to the GloBE information return filing deadline.
