English Guide to Korea Gift & Inheritance Tax (2026 Brackets)
Here's what most expats get wrong: transferring large sums of money across borders or inheriting foreign property doesn't magically bypass South Korea's National Tax Service (NTS). Once you are deemed a resident in Korea, both local and overseas asset transfers enter a strict, highly progressive tax system.

I've run the numbers on this myself for multiple expatriate clients β the difference between proactive estate planning and ignoring Korean tax law is very real. Some families lose half their wealth simply because they missed the proper filing window or failed to utilize statutory exemptions over a 10-year period.
What Are the 2026 Tax Brackets?
The core concept is straightforward but bruising. When you receive a gift or inheritance, the value is tallied up. Korea uses a progressive taxation model, meaning the more you receive, the higher the percentage of tax applied to the upper segments of your wealth.
Below is the unified rate table used by the National Tax Service (NTS) β for both gift and inheritance calculations in 2026. This table applies strictly to the net taxable baseβthis is the value remaining after you've already applied all allowable marital, child, and standard deductions.
| Taxable Base (Net amount) | Marginal Tax Rate | Progressive Deduction |
|---|---|---|
| Up to 100 Million KRW | 10% | None |
| Over 100M ~ 500M KRW | 20% | 10 Million KRW |
| Over 500M ~ 1 Billion KRW | 30% | 60 Million KRW |
| Over 1B ~ 3 Billion KRW | 40% | 160 Million KRW |
| Over 3 Billion KRW | 50% | 460 Million KRW |
To use this chart, multiply your taxable base by the rate, then subtract the progressive deduction. If John inherits a net 700 million KRW base, he sits in the 30% bracket. His tax is (700M Γ 0.30) - 60M = 150 million KRW. The gap is bigger than you'd expect compared to jurisdictions with flat or near-zero inheritance profiles.
Who Actually Pays? The Resident vs. Non-Resident Rule
Korean tax liability hinges on the concept of domicile (resident status). If the deceased was a Korean tax resident, their worldwide assets are subject to the global inheritance tax regime.
"If a donee is a resident, he/he is liable to pay gift tax on all gifted property, regardless of location." β National Tax Service (NTS), Jan 2026.
If you are classified as an expat tax resident inside Korea, you must report overseas cash wiring, inherited foreign real estate, and equity shares transferred from parents abroad. Korea enforces strict tracking and cooperates with international banking standards to verify overseas transfers over a cumulative 10,000 USD equivalent.
How Do Exemptions (Gongje) Defend Your Wealth?
No one pays tax on the absolute gross amount. You must strategically apply your Gongje (곡μ - deductions) which act as a shield to bring down your taxable base. Here is the honest truth about deductions: they are meant to protect normal middle-class wealth, but quickly run out if you are passing down premium Seoul real estate.
For children, the deduction is much tighter. You can gift an adult child up to 50 million KRW tax-free every 10 years (or 20M KRW for a minor). Anything over that amount within a decade triggers a taxable event.
If we talk about inheritance (upon death), the baseline gets a bit more generous. There is a "basic deduction" of 200 million KRW, plus various other family deductions. Alternatively, the law allows a "lump-sum" baseline deduction of 500 million KRW. Thus, if a resident's total estate falls under 500 million KRW, there is generally no inheritance tax owed.
What Are the Strict NTS Reporting Deadlines?
Timing your filing is arguably the most essential compliance step. The NTS sets unforgiving deadlines, and failing to meet them not only removes your early-filing discounts but also piles on penalty interest.
If you've ever been confused by this timeline, you're not alone. An expat might receive a $100,000 international transfer in January, assume their home country tax return covers it next year, and miss the April Korean filing deadline completely. The result? A 20% penalty for no-filing, plus continuous daily interest charges.
Frequently Asked Questions
Are foreign residents subject to inheritance tax on foreign assets?
Yes, residents are taxed globally. If the deceased was a Korean tax resident, their worldwide estate is subject to Korean inheritance tax. If the deceased was non-resident, only Korea-situated assets are taxed.
What is the gift tax limit between foreign spouses in Korea?
The limit is 600 million KRW over 10 years. Spouses can legally transfer up to this amount without incurring gift tax, provided at least one is a Korean resident receiving the asset.
Does Korea have a wealth tax outside of these transfers?
No, there is no separate general wealth tax. However, comprehensive real estate taxes apply annually to individuals owning multiple or high-value residential properties in Korea.
