## Overview of South Korea’s 2026 Tax Reform (세제개편안)
The government unveiled its proposed **2026 tax reform (세제개편안)** in early August 2026, setting out changes that will affect companies across many sectors. Some changes are already enacted; others are still under consideration. ([mof.go.kr](https://www.mof.go.kr/doc/ko/selectDoc.do?bbsSeq=10&docSeq=67823&menuSeq=971&utm_source=openai))
Key proposals include:
- **Tax credits** for corporate clients (“화주”) who enter into long-term (3-year or longer) transport contracts with coastal shipping companies, allowing a **1% credit** against their **corporate or income tax** for eligible transport expenses. ([mof.go.kr](https://www.mof.go.kr/doc/ko/selectDoc.do?bbsSeq=10&docSeq=67819&listUpdtDt=2026-08-13++10%3A00&menuSeq=971&utm_source=openai))
- **Permanent continuation** of various tax exemptions for **fisheries corporations (“어업법인”)**, including corporate income tax exemptions for certain fishing business incomes, dividend income exemptions for members (within certain thresholds), and VAT exemptions for services provided by fishing corporations. Previously, these were scheduled to expire. ([mof.go.kr](https://www.mof.go.kr/doc/ko/selectDoc.do?bbsSeq=10&docSeq=67823&menuSeq=971&utm_source=openai))
- **Extension of duty-free fuel support for fisheries**: Fuel for fishing businesses (“fishing-use fuel”) will continue to be exempt until **December 31, 2029**, an extension of 3 years. ([mof.go.kr](https://www.mof.go.kr/doc/ko/selectDoc.do?bbsSeq=10&docSeq=67823&menuSeq=971&utm_source=openai))
## Entity Compliance Checklist
| Area | Action Item |
|---|---|
| **Corporate Tax & Income Tax** | Identify if your business qualifies for the 1% credit for coastal shipping contracts—check if you are an eligible “화주,” and maintain documentation of contract length and transport invoices. ([mof.go.kr](https://www.mof.go.kr/doc/ko/selectDoc.do?bbsSeq=10&docSeq=67819&listUpdtDt=2026-08-13++10%3A00&menuSeq=971&utm_source=openai)) |
| **Fisheries Corporations** | If you are an English fishing cooperative or similar, document your income types to confirm which portions are exempt (e.g. rule of member dividends under ₩12 million exempt threshold). Prepare to apply the income and VAT exemptions as permanent, no longer time-limited. ([mof.go.kr](https://www.mof.go.kr/doc/ko/selectDoc.do?bbsSeq=10&docSeq=67823&menuSeq=971&utm_source=openai)) |
| **Fuel & Energy Costs** | If your business is in fisheries (or agriculture/forestry), keep detailed fuel purchase and usage records to ensure continued exemption or subsidy. Note that support levels will be tied to future legislation. ([mof.go.kr](https://www.mof.go.kr/doc/ko/selectDoc.do?bbsSeq=10&docSeq=67823&menuSeq=971&utm_source=openai)) |
| **VAT and Supply Contracts** | For businesses acting as “화주” entering long-term contracts, ensure your accounting systems can handle **tax credit reporting**, and ensure supplier invoices clearly identify contract duration and transportation expenses. |
| **Legislative Process Tracking** | Since many reform items are currently *proposed* (입법예고, 법안 예정 제출) before final legislative approval, monitor progress through public announcements or via 국회 when the final bill is passed.

## Practical Scenarios
- **Scenario A: Manufacturer and Coastal Shipping**
- You're a cement producer entering a contract for 3 years+ with a coastal shipping firm for raw materials. Under the new proposals, the transport cost you incur may yield a **1% credit** against your corporate tax base (if incorporated) or income tax (if individual business). This reduces your effective transport cost and improves competitiveness. ([mof.go.kr](https://www.mof.go.kr/doc/ko/selectDoc.do?bbsSeq=10&docSeq=67819&listUpdtDt=2026-08-13++10%3A00&menuSeq=971&utm_source=openai))
- **Scenario B: Fisheries Company**
- If you run a fishing business or are part of an English cooperative, income from fishing operations and member dividends (up to thresholds) has been made permanently exempt. Previously limited-term provisions now may be indefinite. Ensure that you’ve recorded fishing yield, member identities, and taxable income brackets. Fuel purchases and invoices should clearly reflect “fishing-use fuel” to claim VAT or excise exemptions.

## Risk Areas & Common Pitfalls
- Mistaking **“proposed”** reforms (입법예고/세제개편안) for “law already passed.” Some benefits may still change or be rejected in parliament. Ensure you act on **enacted decrees/order when available**.
- Lack of **contract documentation** for long-term ship contracts; if duration or transport costs are not clearly evidenced, tax authorities may deny credit.
- Not tracking **ownership types** in fisheries until they qualify; member-status and whether the entity is an “English fishing co-operative” matters under exemption rules. Thresholds and definitions may restrict eligibility. ([mof.go.kr](https://www.mof.go.kr/doc/ko/selectDoc.do?bbsSeq=10&docSeq=67823&menuSeq=971&utm_source=openai))
- Confusing **fuel exemption** for time scope: planned until end-2029. After that, future budget laws or revisions could cut back. ([mof.go.kr](https://www.mof.go.kr/doc/ko/selectDoc.do?bbsSeq=10&docSeq=67823&menuSeq=971&utm_source=openai))
## Timeline & Effective Dates
- Reforms were **proposed** in early August 2026; currently under **입법예고 (public notice)** from **August 4-20, 2026**, and expected to be submitted to 국회 in September. Final enactment likely in December in line with annual budget adjustments. ([mof.go.kr](https://www.mof.go.kr/doc/ko/selectDoc.do?bbsSeq=10&docSeq=67823&menuSeq=971&utm_source=openai))
- Some measures already in effect (existing exemptions continuing), others upon specified deadlines, such as **December 31, 2029** for fishing-use fuel exemption. ([mof.go.kr](https://www.mof.go.kr/doc/ko/selectDoc.do?bbsSeq=10&docSeq=67823&menuSeq=971&utm_source=openai))
**Bottom line:** Entities in sectors like fisheries and shipping, and businesses entering long-term transport contracts, should immediately adjust accounting, contracts, and records to be ready. Legal review and diligent documentation will ensure you can capture the intended tax reliefs under the 2026 reforms.
