Korean Ancestral Gravesite Land Inheritance Tax Exemption Calculator

Korean gravesite and ritual farmland exemption: area limits and value caps work together

When a parent dies leaving an ancestral gravesite forest and farmland in the countryside, how to report them is one of the most often missed points of a Korean inheritance tax return.
Article 12(3) of the Inheritance and Gift Tax Act exempts ritual property under Civil Act Article 1008-3 within the scope set by Presidential Decree.
Under Decree Article 8(3), grave-guarding forest up to 9,900㎡ and ritual farmland up to 1,980㎡ that belong to the graves are exempt up to KRW 200 million combined, and genealogy records and ritual utensils up to KRW 10 million.
Reporting the gravesite as ordinary estate can mean paying tax on up to KRW 210 million that should have been exempt.

On the other hand, claiming an exemption for area above the limit, for forest unrelated to graves or for leased farmland can lead to an audit, additional tax and penalties.
This calculator takes each parcel’s area, value and whether it actually qualifies, applies the area limits and value caps at the same time, and returns the estimated exempt amount, the taxable remainder and the excess area.
It then runs the 2026 inheritance tax engine twice, with and without the exemption, to show the tax saving, the exposure if the exemption is denied and the amount the rite host succeeds to alone under the Civil Act.

Ritual property limits at a glance

The tax limits and the Civil Act succession look similar but are not the same.
Tax law limits both area and value, while the Civil Act sets only area and has no value cap.

How to use the calculator

1. Choose the inheritance date and the rite host.
   The date sets the filing deadline (six months after the end of the month of death) and the precedent that decides the host when heirs disagree.
   Choose whether one heir, several heirs, or a non-heir hosts, and tick whether the property will be registered to the host.
   
2. Enter the forest and farmland parcels.
   For each parcel enter the type, area and inheritance-tax value, usually the official land price × area or an appraisal.
   Untick “qualifies” for parcels without graves or leased or idle farmland.
   
3. Enter the genealogy and utensils value.
   It is usually small, but check the KRW 10 million cap when old documents or valuable vessels are involved.
   
4. Enter the remaining estate and deductions.
   Remaining estate, debts, funeral costs, the spouse’s actual share, children, net financial assets and gifts within 10 years feed the 2026 deduction rules.
   
5. Review and save the result.
   Check the exempt estimate, taxable remainder, saving, denial exposure and excess area, then save a TXT with the checklist for a tax adviser.
   

Worked fictional example

The deceased died on 2026-09-15 leaving two forest parcels, two farmland parcels and genealogy records, plus KRW 1.6 billion of other estate, KRW 100 million of debts, a spouse and three children.
The filing deadline is 2027-03-31; funeral costs of KRW 10 million, a spouse share of KRW 500 million and net financial assets of KRW 200 million are assumed.

Only 9,900㎡ of the 15,000㎡ forest and 1,980㎡ of the 2,500㎡ farmland fall inside the area limits, and the combined KRW 227.7 million of candidates then hits the KRW 200 million value cap.
Leased paddy D does not qualify as ritual farmland and is fully taxed.
Exempting KRW 205 million removes that amount from the 30% bracket and cuts the tax by about KRW 59.66 million.
If the same amount were claimed and denied, the KRW 61.5 million of additional tax would carry a KRW 6.15 million underreporting penalty and about KRW 3.65 million of late-payment penalty over 270 days.

Civil Act succession versus the tax exemption

Civil Act Article 1008-3 provides that the person who hosts the rites succeeds to grave-guarding forest within 1 jeongbo, ritual farmland within 600 pyeong, genealogy records and ritual utensils.
This special succession sits outside the general estate, so the property leaves the pool the other heirs divide.
Because the Civil Act has no value cap, the host succeeds alone even to value above KRW 200 million, but that excess is still subject to inheritance tax.

Heirs are jointly liable for inheritance tax, but families often share the burden by what each receives, so recording this amount in the partition agreement helps settle accounts among siblings.

Who hosts the rites? Precedent by period

Co-heirs decide the rite host by agreement first.
When they cannot agree, case law decides, and in its en banc decision 2018Da248626 of 2023-05-11 the Supreme Court changed the rule and held that the new rule applies only to ritual property succession after the decision.
The applicable rule therefore depends on the inheritance date.

The calculator does not resolve disputes over the rite host.
It shows which rule applies to the inheritance date so that siblings share the same baseline before writing an agreement.
