Administrative Filing Services for the Four Major Social Insurances

Four major social insurance filings fall into two groups: the establishment report made when a workplace first becomes covered, and the qualification reports made each time a worker is hired, leaves or has their details change. For employment and industrial accident insurance, the establishment report is due within 14 days of the date the insurance relationship is established (Act on the Collection of Insurance Premiums, Article 11), and the acquisition or loss of an insured worker's status must be reported by the 15th of the month following the month in which it occurred (Enforcement Decree of the Employment Insurance Act, Article 7). Acquisition of employee health insurance status is reported within 14 days (National Health Insurance Act, Article 8), and the national pension report for a mandatorily covered workplace is due by the 15th of the following month (Enforcement Rule of the National Pension Act, Article 3); all of these can be filed at once through the 4 Social Insurance Information Center. We organize the workplace details and each worker's start date and pay, prepare the insurance forms and file them on the employer's behalf.
