A Guide to the Latest 2026 Four Major Insurance Rates, Calculation Methods, and Enrollment Criteria for Short-Term Part-Time Work
1. Basic Concepts and Types of the Four Major Insurance
The Four Major Insurance, managed by relevant institutions such as the National Health Insurance Corporation (NHIS) and the Workers’ Compensation and Welfare Service (WCWS), is a collective term for the National Pension, Health Insurance, Employment Insurance, and Industrial Accident Insurance. This system serves as a sturdy fence that protects the minimum standard of living against various risks we may face in life, such as old age, illness, unemployment, and industrial accidents. When you first get a job, the company is legally obligated to enroll the employee in these four insurances; failure to do so can result in legal sanctions. In fact, Mr. Kim, who started a part-time job at a small local shop, once witnessed the owner delaying enrollment due to the burden of insurance premiums, only to deeply regret it later. Thus, the Four Major Insurance is not merely a system that deducts money, but an essential safety device to protect your future self. As a public system established by the state to guarantee the basic quality of life for its citizens, every employee should accurately understand its contents to properly safeguard their rights. The National Pension is a system that helps ensure a stable retirement by providing a monthly pension from the state when one becomes too old to engage in economic activities. Health Insurance was created to alleviate the burden of massive medical costs when visiting large hospitals for sudden illnesses or injuries; it also includes Long-Term Care Insurance to support elderly people with mobility issues. Employment Insurance is a valuable system that provides unemployment benefits for a certain period and assists with vocational training when one loses their job. Finally, Industrial Accident Insurance is an insurance where the employer bears the full cost, allowing employees to receive medical expenses and compensation if they are injured or fall ill while working. Because these four systems work organically together, our society can be maintained safely. While the money deducted from your monthly salary may feel like a waste, these are the very systems that reach out to you first in moments of life’s crises.
The Four Major Insurance consists of four essential systems that guarantee basic risks for citizens, protecting us from old age, illness, unemployment, and industrial accidents.
2. Four Major Insurance Rates and Individual Burden Ratios as of 2026
The Four Major Insurance rates deducted from monthly salaries are adjusted or maintained each year to reflect economic conditions and inflation rates. What employees are most curious about is how directly this affects their actual take-home pay. For example, for an employee with a monthly salary of 2.5 million won, the combined individual burden for the National Pension, Health Insurance, and Employment Insurance results in a source deduction of over 200,000 won per month. Additionally, the employer must match this amount or pay even more, meaning the labor cost burden for business owners is also significant. In fact, labor cost management and the administration of the Four Major Insurance are the most heavily emphasized topics when small business owners receive labor law training. Knowing the exact rates in advance is essential to avoid errors when calculating salaries or planning business operations. Specifically, the National Pension is operated by having employees and employers share the burden equally based on a certain percentage of the standard monthly income. Health Insurance is also split equally between the employee and the company, with an additional Long-Term Care Insurance premium levied based on a certain percentage of the health insurance premium. Employment Insurance costs are divided into unemployment benefits and employment stability/vocational development costs, which are also shared by both the employee and the employer. In contrast, Industrial Accident Insurance differs significantly from the other three in that employees bear no cost, and the employer covers the full amount. Occasionally, there are incidents where new employees, unaware of this fact, mistakenly believe the company is failing to deduct the industrial accident insurance premium from their pay. Carefully reviewing the rate tables published each year allows you to clearly grasp which items in your salary are increasing or decreasing by how much.
Four Major Insurance rates are shared between employees and employers depending on the item, while Industrial Accident Insurance is fully borne by the employer.
3. Enrollment Criteria for Short-Term Part-Time and Daily Workers
It is very common to be confused about whether one must enroll in the Four Major Insurance when working part-time jobs such as selling holiday gift sets or working at short-term events. To conclude, even for short-term workers, the types of insurance required for enrollment vary completely depending on the duration and hours of work. For short-term part-timers who work briefly on weekends, Employment Insurance and Industrial Accident Insurance are unconditionally applicable from the moment they start working, regardless of the employment period. However, National Pension and Health Insurance are only included in the enrollment scope if the person works for 8 days or more in a month or exceeds a certain standard of working hours. Mr. Park, a university student who worked as a gift wrapper at a department store during the Lunar New Year or Chuseok, was relieved to see his statement showing that only Employment Insurance was applied and no pension was deducted because he had only worked for a few days. If you do not accurately understand the criteria based on the type of part-time work, it is easy to misunderstand that an incorrect amount has been deducted from your salary. If small business owners do not properly know these criteria when hiring part-timers, they risk getting involved in wage arrears or labor-related disputes later on. According to the Labor Standards Act, even short-term workers must have a contract written, and if they meet the legal standards, the corresponding insurance premiums must be reported and paid. Especially in today’s era where platform labor and short-term jobs are active, it is important to have the habit of carefully recording your own working days. Even if you work short stints at multiple places in a month, you must aggregate the working conditions at each workplace to see if the criteria are met to avoid trouble. Both employers and employees must clearly understand these criteria to reduce unnecessary misunderstandings and create a fair labor environment. Whether you are looking for a part-time job or hiring staff as a business owner, these insurance enrollment criteria are not optional but essential common sense.
For short-term part-time work, Employment Insurance and Industrial Accident Insurance are applied immediately regardless of duration, while National Pension and Health Insurance are applied only if working 8 days or more per month.
4. Disadvantages of Non-Enrollment in the Four Major Insurance and Methods for Retroactive Application
If you quit a job after working without enrolling in the Four Major Insurance due to the company’s difficult circumstances or other reasons, you may face significant disadvantages. The most representative problem is being excluded from receiving unemployment benefits after quitting because the Employment Insurance history is missing. In fact, news often reports cases where individuals who worked diligently for years at a company could not receive unemployment benefits and were left scrambling because the employer failed to report them. In such cases, the worker must gather documents that can prove they actually worked at that workplace. Bank deposit records for salary, messenger conversations related to work, and labor contracts can be used as strong evidence. If the evidence is solid, you can have your insured status recognized retroactively through the National Health Insurance Corporation or the Workers’ Compensation and Welfare Service and confidently reclaim your overdue rights. Conversely, from the employer’s perspective, non-enrollment in the Four Major Insurance is a serious legal risk that should never be taken lightly. If a complaint is filed with the Ministry of Employment and Labor or an investigation is conducted by the NHIS, the employer may have to pay not only the unpaid insurance premiums but also massive penalties all at once. This is why there are so many heartbreaking stories of small business owners who tried to save on labor costs but ended up facing bomb-like additional charges and having to close their shops. Therefore, employers must honestly enroll employees in the Four Major Insurance immediately upon hiring, and employees need the wisdom to periodically check if their rights are being properly protected. When both parties faithfully fulfill their legal obligations, unnecessary conflicts can be prevented, and healthy economic activities can continue. If you have any missing history, it is wise to contact the relevant institutions immediately to correct it rather than delaying.
Non-enrollment in the Four Major Insurance can make it difficult to receive unemployment benefits; rights can be recognized retroactively with evidence, or employers may face penalties.
5. Benefits of Automatic Transfer Application and Convenient Payment Methods
Checking the Four Major Insurance notice that arrives every month in the mailbox and paying it directly at the bank or online one by one is more cumbersome than one might think. The National Health Insurance Corporation actively recommends the automatic transfer system to resolve this payment inconvenience for the public and prevent the payment of surtaxes. By applying for automatic transfer, you can fundamentally block the worry of late fees caused by forgetting the payment date, and you can reduce one more thing to worry about in your hectic daily life. Additionally, the corporation often runs various prize draw events for automatic transfer subscribers or provides small payment discount benefits. You can easily link your account or card for automatic transfer in just a few minutes through the smartphone app or the official website. For busy modern people, a system that simplifies such minor administrative procedures is a very grateful feature that improves quality of life. For employees, the company handles the deduction from their salary and processes it, but regional subscribers or those running personal businesses must manage their insurance premiums themselves. In such cases, if automatic transfer is not set up, it often happens that they miss the payment deadline during busy work and unfairly incur unnecessary late fees. Applying for automatic transfer can be easily handled via telephone or internet grievance services without visiting a nearby branch in person. Since it is automatically deducted on a set date each month, it is also a great help for systematic money management. If you are still receiving notices directly, we recommend switching to automatic transfer this time to enjoy the convenience in your life. Small changes in habits can completely resolve unnecessary expenses and stress.
Applying for automatic transfer of the Four Major Insurance prevents the risk of late payment and increases payment convenience along with various prize benefits.
6. Future Outlook of the Four Major Insurance and Action Guidelines Employees Must Know
As society ages and the population structure changes rapidly, the Four Major Insurance system is expected to undergo continuous changes and reforms. Looking at the trend of rates being adjusted slightly each year, it is easy to guess that the social costs we will have to bear in the future will gradually increase. In the midst of these changes, both employees and employers must not treat the changing system as someone else’s business but must maintain continuous interest to prevent financial damage. Even if the amount deducted from your salary feels like a waste, you must remember that it is the only means to protect our retirement and safety net. You must cultivate the ability to check whether your enrollment status is accurately reflected every time you change jobs or start a new business. To solidify the economic future of yourself and your family, you must start by carefully examining your current salary statement and insurance premium payment records. As a specific action guideline, try to develop the habit of checking once a month on payday whether the deducted Four Major Insurance amount is calculated accurately. If you are preparing to change jobs, you must check in advance whether the Employment Insurance qualification loss report was properly processed at your previous workplace to avoid issues when applying for unemployment benefits. For business owners, it is a top priority to frequently check the latest labor training or guidance from relevant institutions to prevent disadvantages due to legal violations. If you pay attention to news about government policy changes or rate increases and plan your funds in advance, you can flexibly respond to any economic changes. Since the Four Major Insurance is a system most closely tied to our lives, never forget that you can only protect and enjoy what you know. We hope that the reality of the complex social insurance system has been clearly resolved through this time, and we cheer for you to continue a wise economic life.
The Four Major Insurance system is continuously reformed to adapt to changing environments, so you should periodically check your enrollment status and respond wisely.
