Most foreign investors researching Korea still come across references to a broad corporate tax holiday for foreign-invested companies — a multi-year exemption that made Korea an unusually attractive destination for new investment. That system did exist, and for years it was a genuine centerpiece of Korea’s foreign investment pitch. It was also phased out starting in 2019, and a surprising number of investors, advisors, and even foreign subsidiaries already operating in Korea are still planning around an incentive structure that no longer applies to new investment.

What replaced the old system is narrower, more conditional, and split across several different mechanisms rather than one unified tax holiday: customs and import tax exemptions, local tax reductions, cash grants, special economic zone benefits, and general tax credits that happen to be available to foreign-invested companies but were never designed specifically for them.

The Corporate Tax Holiday Most Investors Still Assume Exists — It Doesn’t Anymore

What the Old System Offered

Korea’s former foreign investment tax reduction system allowed qualifying foreign-invested companies — generally those bringing advanced technology in designated growth industries, or investing in specific zones — to receive a full corporate and income tax exemption for several years, followed by a partial reduction for a further period, commonly structured as full exemption for three to five years followed by fifty percent relief for two more years.

Why It Was Phased Out

The system was wound down starting with a 2018 tax reform announcement, largely in response to international pressure. The European Union had listed Korea as a non-cooperative tax jurisdiction in late 2017, citing concern that Korea was using targeted tax incentives to attract high-value foreign investment in a way that eroded other countries’ tax bases — concerns closely aligned with the OECD’s base erosion and profit shifting agenda. Korea committed to reform in response, and the corporate and income tax reduction provisions were repealed for new applications.

The Practical Cutoff Date

The corporate and income tax reduction under the old system applies only to foreign-invested companies that filed their tax reduction application before the end of 2018. Any foreign investment notification and tax reduction application filed from January 1, 2019 onward falls outside the old system entirely — a distinction that matters enormously for a foreign investor comparing notes with an existing subsidiary that was established years earlier, or relying on outdated advisory material that predates the reform.

What Actually Survived: Customs and Import Tax Exemption on Capital Goods

What Qualifies

A foreign-invested company can still receive exemption from customs duty, individual consumption tax, and value-added tax on capital goods imported specifically as part of the foreign investment — meaning goods introduced through the foreign investment notification, funded by the foreign investor’s capital contribution, or contributed directly as investment in kind. Capital goods purchased with funds unrelated to the foreign investment itself, or shares acquired on the secondary market rather than through new share issuance, don’t qualify.

The Import Window and Extension

The exemption requires that the capital goods actually complete customs import procedures within five years of the foreign investment notification date, with a possible one-year extension available on application to the Ministry of Economy and Finance where the delay resulted from circumstances genuinely outside the company’s control.

Clawback Triggers

This exemption isn’t unconditional once granted. It can be revoked and the exempted amount clawed back if the foreign-invested company later merges, dissolves, or otherwise violates the conditions attached to the exemption — though certain events, such as a share transfer connected to an IPO or an unavoidable disposal of the underlying assets, are generally treated as exceptions rather than triggering clawback.

Local Tax Reduction: Where the Real, Ongoing Savings Now Live

Acquisition Tax and Property Tax

With the national corporate and income tax holiday gone, local tax reduction has become the more durable remaining benefit for many foreign-invested companies — specifically, reduction of acquisition tax on real property acquired for the business and reduction of the ongoing property tax on that property, available for periods that can run up to fifteen years depending on the specific local ordinance and location.

Why This Gets Overlooked

Because the local tax reduction runs through a different legal framework and a different application process than the old corporate tax holiday did, foreign investors and their advisors sometimes miss it entirely while focused on the (now largely unavailable) national tax reduction, or fail to apply within the correct window relative to the property acquisition and foreign investment notification.

Free Economic Zones and Foreign Investment Zones: Where Benefits Stack

The Zones Still Carry Meaningful National-Level Benefits

Foreign-invested businesses located within Korea’s Free Economic Zones, individual or complex-type Foreign Investment Zones, or Free Trade Zones can still access a materially richer incentive package than a foreign-invested company operating elsewhere. This commonly includes full tariff exemption for five years on imported capital goods, local acquisition and property tax exemption running up to fifteen years, and — separate from tax entirely — long-term land leases at a small fraction of assessed land value and infrastructure support that can cover a substantial share of site development costs.

Employment and Training Support Layers on Top

Companies in these zones with a foreign investment ratio of 30% or higher can also negotiate cash assistance covering factory and research facility costs, employment subsidies, and training program support, with R&D center investment support sometimes covering a significant share of qualifying costs. None of this is automatic — it’s generally negotiated with the relevant zone authority or investment promotion agency as part of the initial investment planning.

Cash Grants: Korea’s Replacement for the Old Tax Holiday

A Deliberate Substitute, Not an Afterthought

Korea’s cash grant program for foreign investment functions as the government’s intended replacement for the tax holiday it gave up under international pressure — a direct subsidy rather than a tax reduction, which sidesteps some of the international tax-competition concerns that led to the old system’s repeal. Eligibility and amount are generally tied to investment scale, the strategic value of the technology or industry involved, and the number of jobs created, and these grants are negotiated case by case with the investment promotion authorities before the investment is finalized.

Why This Requires Earlier Engagement Than a Tax Filing Does

A foreign investor used to thinking of tax incentives as something handled by tax counsel after the investment structure is already set has to adjust for this: a cash grant application is fundamentally a negotiation that needs to start during the investment planning phase, often well before the Korean entity is even incorporated.

R&D and Investment Tax Credits: Not Foreign-Investment-Specific, Often the Biggest Number

Available to Any Qualifying Company, Foreign-Invested or Not

Separately from anything specific to foreign investment, Korea offers a general integrated investment tax credit covering facility and R&D investment in designated strategic and emerging technology areas — including semiconductors, batteries, vaccines, and hydrogen among others — with credit rates that vary by company size and technology category, generally more generous for smaller companies than for large enterprises. A foreign-invested company qualifies for these credits on the same basis as any other Korean-incorporated company undertaking the same kind of investment.

Why Foreign Investors Sometimes Miss This Entirely

Because these credits aren’t marketed or administered as part of the “foreign investment incentive” package, a foreign investor focused narrowly on FDI-specific benefits can overlook a credit that, in practice, is often larger in absolute terms than everything in the foreign-investment-specific package combined — particularly for a technology-intensive business making substantial R&D or facility investments.

Practical Sequencing for Planning Around What’s Actually Available

  1. Confirm upfront that the national corporate and income tax reduction no longer applies to your investment, rather than discovering this after structuring decisions have already been made around an assumed tax holiday.
  2. Evaluate site selection against Free Economic Zone, Foreign Investment Zone, and Free Trade Zone status early, since the richest remaining package of national and local benefits is tied to location, not just to the nature of the investment.
  3. Time the capital goods import plan against the five-year exemption window from the foreign investment notification date, and apply for the extension in advance if a delay is genuinely likely.
  4. Open cash grant negotiations during the investment planning phase, not after incorporation, since this is a negotiated benefit that has to be built into the investment decision.
  5. Separately evaluate the general R&D and investment tax credit regime on its own merits, since it’s often the largest available benefit and isn’t conditioned on foreign investor status at all.
  6. Build clawback conditions into your post-investment compliance calendar, particularly around capital goods exemptions and local tax reductions, since these benefits remain conditional and can be reversed with interest if conditions lapse.
