    Jeonse fraud victims are guaranteed at least one third of the deposit

    Now

    Even after auction proceeds and public support, there is no floor on how much of the deposit comes back.

    From that date

    Where distribution, repayment and support together come to less than one third of the deposit, the victim applies for the shortfall. A decision follows within 90 days. Victims recognised before the start date are covered, and so are those whose auction closed before it. The enforcement decree (Presidential Decree 36754, promulgated 2026-10-13) puts the counter at the Korea Land and Housing Corporation (LH), and adds the auction margin (appraised value less winning bid) and rent support already paid to the amounts deducted. The claim is filed once the property has been disposed of, or once the auction margin has been worked out. Online filing through LH Apply Plus opens first, on 2026-11-10; filing in person or by post at an LH regional office opens on the start date, 2026-11-13. Four groups may not claim: those without Korean nationality, tenants whose deposit exceeds KRW 500 million, those who bought the property themselves, and those who filed no demand for distribution or allocation (though a claim is still open where the auction first began before 2026-11-13). The claim must be made within three years of being recognised as a victim or within one year of the auction closing; those recognised before the start date have until 2029-11-13. Local government grants and financial support do not count as recovery, so they do not reduce the payment. (MOLIT, 2026-11-09)

    Victims who contracted with someone with no right to lease are paid the minimum first

    Now

    Nothing is settled until the auction and distribution are over, and until then the deposit does not come back.

    From that date

    A victim who contracted with a person holding no lawful right to lease (trust fraud included) receives the minimum guarantee of one third of the deposit up front, and it is squared later against what distribution and repayment bring. Opposing power must be kept until that settlement, and public rental housing support is not available. Under the enforcement decree (Presidential Decree 36754, promulgated 2026-10-13) the counter is the Korea Land and Housing Corporation (LH), and the advance is one third of the deposit less only what the claim for return has repaid and the rent support paid up to that point. It must be claimed before LH completes its purchase or the property is disposed of, and missing the deadline to return money once a ground to return arises carries a fine of 15 million won for a first breach, 20 million for a second and 30 million from the third on. The procedure for claiming, payment, objection and return is set by the enforcement rule (MOLIT Ordinance 1632, promulgated 2026-10-13). Online filing through LH Apply Plus opens first, on 2026-11-10; filing in person or by post at an LH regional office opens on the start date, 2026-11-13. The claim must be made within three years of being recognised as a victim or within one year of the auction closing; those recognised before the start date have until 2029-11-13. Where LH's purchase later produces a margin, that much is paid on top, so the settlement does not run only one way. (MOLIT, 2026-11-09)

    Professional investors may subscribe for an IPO before the registration statement is filed

    Now

    Subscriptions may only be solicited after the registration statement is filed.

    From that date

    For shares not yet listed, demand may be gauged among professional investors before filing and part of the offering may be subscribed in advance. Shares allotted in advance are locked up for at least six months, and the ceiling on volume is set by Presidential Decree. ✅ **On 3 November 2026 the Cabinet approved the amended Decree, filling in what the Act had left to it** (promulgation due in November; commencement 13 November 2026, the same day as the Act). The lock-up is staggered across the allotment: **50% for six months, 30% for eight months and 20% for ten months**, so that the lock-ups do not all expire on one day and trigger a wave of selling. The Decree itself only sets a range of six to twelve months; the final split sits in the Korea Financial Investment Association’s Regulation on Securities Underwriting Business. The ceiling applies to the institutional tranche left after retail investors, the employee stock ownership association and policy funds (high-yield and KOSDAQ venture funds): on KOSPI **20% in aggregate and 10% per investor**, on KOSDAQ **30% in aggregate and 20% per investor**. Converted to the whole offering that is 10% and 5% on KOSPI, and 4.5 to 10.5% and 3 to 7% on KOSDAQ. A cornerstone investor must hold own capital, or entrusted assets, of at least **20 times** the volume it subscribes for in advance, and institutional investors with a stake in the issuer (major shareholders, related parties) are barred from such a contract outright. 🔴 **Nothing used to compute capital gains tax on shares changes.** What changes is how an IPO is allotted.

    A three-year limitation period is created for imposing health insurance contributions

    Now

    No provision says how long contributions may be imposed. Only the three-year prescription on the right to collect exists.

    From that date

    Contributions and surcharges may not be imposed once three years have passed from the day they could be imposed, or six years where fraudulent means were used. For deferred notices the clock starts the day after the deferral ends, and where litigation intervenes a corrected imposition may be made within one year of the decision becoming final.

    An employer who approves reduced working hours for childcare must say so within 14 days

    Now

    The employer has to give written reasons only when it **refuses** a request for reduced working hours during the childcare period (육아기 근로시간 단축). There is no procedure for telling the worker when it approves, so the worker has to arrange care and shifts without knowing when the reduction starts.

    From that date

    Where the employer approves, it must now notify the worker in writing or by electronic means **within 14 days of receiving the request**. 🔴 **No part of the benefit formula or its amounts changes.** What changes is the employer's duty to notify. The eligibility conditions are unchanged too: a child aged 12 or under, or in the sixth grade of elementary school or below, and 15 to 35 working hours a week. The article number of the Decree is not given in the press release, and the Decree has not yet been promulgated, so the sole source is the Ministry of Employment and Labor's release of 3 November 2026.

    Labor inspectors are renamed and unannounced visits become the rule for workplace inspection

    Now

    Inspectors sit under the Labor Standards Act within the Ministry of Employment and Labor, and internal rules decide the kinds and methods of inspection.

    From that date

    Powers and procedures are gathered into one Act, inspections are divided into regular, occasional and special, and the unannounced visit becomes the rule. Inspection of workplaces with fewer than 30 workers may be delegated to metropolitan and provincial governments, which may appoint local labor inspectors.

    A four-hour shift may skip the 30-minute break if the worker asks for it

    Now

    A four-hour shift must include at least 30 minutes of rest taken during the shift. There is no exception even when the worker would rather not take it, so four hours of work means four and a half hours on the premises.

    From that date

    A proviso is added: the duty does not apply where the shift is four hours and the worker has expressly asked not to take the break. The one-hour break in an eight-hour shift is unchanged. Note that the request must come from the worker, not the employer. The provision only lifts the employer's duty to grant the break; it does not give the employer a right to demand that the worker waive it.

    Wage costs must be separated out of the contract price and paid monthly

    Now

    The contract price is paid as a single sum. The share of it that belongs to the subcontractor's workers as wages is not identified, so it does not show when the money goes somewhere else.

    From that date

    The principal contractor must separate the wage portion of the contract price and pay it monthly. Depositing it with a financial institution designated by the Minister of Employment and Labor counts as payment. The principal must check whether the subcontractor paid last month's wages and report to the Minister if it did not. The subcontractor may not use the wage costs it receives for anything other than wages. The scope covers the State, local governments, public institutions, local public corporations and agencies, and locally funded bodies, plus a sixth category ("any other principal contractor not falling under items 1 through 5"), so private parties are included. Which industries, contract sizes and durations are actually caught has not yet been set by Presidential Decree.

    Tax on gains from transferring or lending virtual assets begins (KRW 2.5 million deducted, 22% taxed separately)

    Now

    Money made by selling or lending virtual assets is not taxed. The charging provision was written in 2020, but the start date was pushed back three times: 2022, then 2023, then 2025, now 2027.

    From that date

    Gains from transfer or lending become other income. Actual acquisition cost and fees are deducted as necessary expenses, KRW 2.5 million is deducted from the year's income, and what remains is taxed separately at 20% (22% including local income tax). Below KRW 2.5 million there is no tax. It is not aggregated into global income, and losses are not offset against other income. For assets held from before 1 January 2027, the acquisition cost is the larger of the actual cost and the market value as of 31 December 2026 (Article 37(5); Enforcement Decree Article 88(2)). That market value is the average of the prices posted at 00:00 on 1 January 2027 by the exchanges designated by the NTS Commissioner. The crypto tax calculator works out the tax in advance from the sale proceeds, the cost and the 31 December 2026 market price.

    From that date

    For the 2027 tax year the threshold becomes 10. The Addenda raise it by one year at a time over four years (11 in 2028, 12 in 2029), reaching the 13 in the main text for the 2030 tax year. The credit amounts themselves do not change.
