Korean Lease Reporting Checker

When you sign a lease on a home in Korea, contracts above a certain size have to be reported to the local government. Enter three things, the deposit, the monthly rent and the contract date, and this calculator answers three questions: whether your lease has to be reported, if so on what ground, and by when. It compares the deadline with today and counts the days left, or the days overdue if you have already passed it.

It also tells you whether a fine can apply to your contract. For some time after the reporting system started there was a grace period during which nothing was charged for failing to report. That period ended on 31 May 2025. Contracts signed on or after 1 June 2025 are fined if the report is missed. Enter the contract date and you see which side of that line you are on.

Tenants and landlords right after signing. The duty falls on both parties, and the deadline is 30 days from the contract date. It counts from the day the contract is signed, not from the day the balance is paid or the day you move in. Wait until the move-in two months later and you have already missed it.

People renewing or amending a lease use it too. A renewal that changes the deposit or the rent has to be reported afresh, and so does an early termination; only a renewal on unchanged terms is exempt. The people who need it most are those who skipped reporting in the past and saw no consequence. That was the grace period; it is over now.

The rule is the residential lease reporting provision of 부동산 거래신고 등에 관한 법률 and its enforcement decree. A residential lease must be reported when the deposit exceeds ₩60 million or the monthly rent exceeds ₩300,000. Either one is enough, and "exceeds" means strictly more, so a jeonse deposit of exactly ₩60 million is not caught. There is also a geographic condition: counties (군) inside metropolitan cities and Gyeonggi-do are covered, but county areas in the other provinces are not.

The calculation runs in two branches. First it checks the deposit against its threshold and the rent against its threshold, which settles whether the lease is reportable and why. Then it adds 30 days to the contract date to get the deadline and compares that with today to count days remaining or days overdue. Whether a fine applies is decided by whether the contract date is on or after 1 June 2025.

Failing to report, or reporting late, carries a fine of between ₩20,000 and ₩300,000; reporting false figures carries ₩1,000,000. You can report at the community service centre or online through the real estate transaction management system, and submitting the contract gives it a fixed date (확정일자) automatically. If one party files with the contract attached, it counts as a joint report by both.

Suppose you signed a jeonse lease with a ₩100 million deposit on 20 July 2026. The deposit exceeds ₩60 million, so the lease is reportable, and with no monthly rent the deposit is the only ground. The deadline is the contract date plus 30 days, 19 August 2026. Because the contract date is after 1 June 2025, missing that date means a fine.

If instead you signed on the same day for a ₩50 million deposit and ₩400,000 a month, the deposit is under the threshold but the rent is above ₩300,000, so it is reportable all the same. Open the calculator on 25 August and it shows the deadline as 6 days past. Even then, reporting now beats leaving it: the shorter the delay, the lower in the range the fine is set.

Counting the 30 days from the balance payment is the most common error; they run from the day the contract was signed. Next is assuming the estate agent will take care of it. An agent can file on your behalf, but the duty sits with the landlord and tenant, and if it is not done the fine lands on them. Checking with the agent once after signing is the safe habit.

Treating the fixed-date stamp and the report as separate steps is also common. Filing the report with the contract attached grants the fixed date at the same time, so there is nothing further to obtain. The reverse also happens: people get the fixed date at the community centre and assume that was the report, so confirm the report was processed alongside it. Finally, do not confuse this with the residence registration (전입신고). That moves your address; the lease report discloses the contract. They are different procedures. This calculator looks only at amounts and dates, so if your case turns on location or on a non-residential building, check those conditions separately.
