Some workers only find out when they leave that their employer never reported them to employment insurance. Article 17 of Korea’s Employment Insurance Act lets an insured person, or a person who was insured, ask at any time for confirmation that insured status was acquired or lost, and Article 15(3) lets the worker file the report if the employer doesn’t. But a late report does not reach back forever. Article 50(5) cuts off anything earlier than 1 January of the year that falls three years before the report (or confirmation) date, treating the person as insured from that 1 January when counting the insured period. Enter the hire date, report or confirmation date and leaving date to see where the counted period starts and how much is cut.
1. Confirmation can be requested “at any time” (Art. 17(1)). If the employer doesn’t report, the worker can, with papers proving the employment such as the contract (Art. 15(3); Enforcement Decree Art. 8).
2. The insured period reaches back only to 1 January three years earlier (Art. 50(5)). A report on 9 November 2026 counts from 1 January 2023 — hired 4 March 2019 and leaving 31 October 2026, 7 yr 7 mo 28 d becomes 3 yr 10 mo.
3. The exception is proof that premiums were paid continuously — then the period premiums were paid counts (Art. 50(5) proviso).
Calculator
Results update as you type. Dates as YYYY-MM-DD. Periods run from the start date through the leaving date, shown in years, months and days (our count). This covers only the Article 50 insured period — the unit period that decides eligibility (Art. 41) and the benefit days (Annex 1) are counted separately.
The provisions — text
| Provision | What the text says | Worth noting (our gloss) |
|---|---|---|
| Art. 17(1) | An insured person or a person who was insured may at any time request the Minister of Employment and Labor to confirm the acquisition or loss of insured status. | Possible after leaving too — no deadline is written |
| Art. 17(2)–(3) | The Minister confirms on request or ex officio and notifies the requesting insured person, the employer and other parties. | Decree Art. 11(2): notice to the requester and the employer or subcontractor who employed them |
| Art. 15(3) | If the employer fails to report insured status, the worker may report it as the Presidential Decree provides. | Decree Art. 8: submit papers proving the employment, such as the contract |
| Art. 50(5), main text | For an insured person whose acquisition had not been reported, if the day they became insured is before 1 January of the year three years back from the report or confirmation date, they are treated as acquiring status on the first day of the insurance year containing the date three years back. | The cut is by year — 1 January of that year, not the same date three years earlier |
| Art. 50(5), proviso | If it is proved that the employer kept paying premiums for that person from before that 1 January, the insured period is the period for which premiums were paid. | Report missing but premiums paid — with proof, nothing is cut |
In Article 50(5), the “report date” is the day the acquisition report under Article 15 was made (item 1) and the “confirmation date” is the day acquisition was confirmed under Article 17 (item 2). A report filed by the worker is still an Article 15 report, so we read it under item 1 (our reading).
How the calculator counts — our gloss
| Line | Rule | Worth noting (our gloss) |
|---|---|---|
| Cut-off | 1 January of (report year − 3) | The year of the date three years back is always year − 3, even from 29 February |
| Start | The cut-off if hired before it; otherwise the hire date | Hired exactly on the cut-off: nothing is cut (the text says “before 1 January”) |
| Proviso | If proven premiums begin before the cut-off, start = the later of the hire date and that day | Whether the proof holds is for the Workers’ Compensation and Welfare Service or job centre |
| Period | Start through the leaving date (inclusive), in years, months and days | Art. 50(3): the insured period is the time employed at the workplace at leaving |
Three results — our examples
| Case (our example) | Result | Worth noting (our gloss) |
|---|---|---|
| Hired 4 March 2019, left 31 October 2026, reported 9 November 2026 | Cut-off 1 January 2023. Actual 7 yr 7 mo 28 d → counted 3 yr 10 mo | 4 March 2019 to 31 December 2022 drops out |
| Same person reports on 4 January 2027 | Cut-off 1 January 2024. Counted 2 yr 10 mo | A new year drops a whole year more — don’t wait past December |
| First case, with premiums proven from 1 January 2020 | Start 1 January 2020. Counted 6 yr 10 mo | Art. 50(5) proviso |
Someone hired after the cut-off, say on 1 June 2023, loses nothing. This applies only to the insured period — the Article 41 unit-period provision does not contain the Article 50(5) sentence (compared article by article). The unit-period count is in the insured unit period calculator.
When the report was never filed
- Check first — see whether your insurance record shows no acquisition date, or a late one.
- Report it yourself — if the company won’t, file with papers proving employment such as the contract or salary transfers (Art. 15(3); Decree Art. 8).
- Request confirmation — ask for confirmation of acquisition or loss (Art. 17(1); Decree Art. 11(1)). The result goes to you and the employer.
- The employer’s deadline — employers report by the 15th of the month after the event. The dates are in the employment insurance report deadline calculator.
Checklist
- ☐ Contract and first payslip proving the hire date
- ☐ Report or confirm before the year turns — the cut-off moves a year
- ☐ Records of premiums deducted from pay (the proviso speaks of the employer paying)
- ☐ Check the unit period on the separation certificate too
- ☐ Re-check benefit days against the counted insured period
Questions that remain
Premiums came out of my pay but the company never paid them?
The Article 50(5) proviso says “proved that the employer … kept paying.” How a deduction without payment is treated isn’t written in this provision, so the calculator doesn’t decide it. Bring payslips to the Workers’ Compensation and Welfare Service or job centre and have it confirmed.
Does the cut stop me getting unemployment benefit?
The period requirement for eligibility is set by Article 40, using the 18 months before leaving among other bases, and the unit period is counted under Article 41. Article 50(5) attaches to the insured period that sets the benefit days, so a cut can reduce the days you get. The day table is in the unemployment benefit calculator.
Can I ask long after leaving?
Article 17(1) lets “a person who was insured” ask “at any time.” Job-seeking benefit itself is paid within 12 months from the day after leaving (Art. 48(1)).
How long can unpaid premiums be collected?
Premium Collection Act Art. 41 says the right to collect premiums and other charges, or to get them back, lapses if not used for 3 years (1), with the Civil Act covering anything the Act does not (2). Art. 42 says the period is interrupted by a monthly premium notice, a refund claim, a notice or reminder, or a demand or seizure in enforcement, and starts again after the notified or reminder due date and so on (checked 9 November 2026). This 3 years is about collecting premiums; it is a different article from the retroactive coverage period the calculator works out (our reading).
