While the 'National Pension' is familiar to employees and self-employed individuals as a monthly insurance premium, many do not know exactly how long they must pay it or how they will receive the pension in old age. In particular, as institutional changes surrounding the insurance premium burden and old-age benefit system begin in full scale this year, there is a growing movement to re-examine the National Pension for retirement preparation.

■ National Pension vs. Old-Age Pension: What's the Difference? The core of the National Pension lies in providing a steady income in old age. It is a system where individuals pay insurance premiums during their working or business years, and upon meeting certain requirements, receive a monthly pension after retirement. In addition to complementing living expenses in old age, it also serves as a social insurance system that supports the livelihood of the individual or their survivors in the event of disability due to illness or accident, or the death of the subscriber.

While the 'National Pension' and 'Old-Age Pension' are often considered the same, the National Pension refers to the entire system, and the Old-Age Pension is one of its benefits. What is received in old age is the Old-Age Pension, what is received upon the onset of a disability is the Disability Pension, and what is paid to eligible survivors upon the subscriber's death is the Survivor's Pension. Unlike private pensions, the payment amount is adjusted to reflect changes in the consumer price index even during receipt, which has the advantage of defending against a long-term decline in purchasing power.

■ Eligibility and Premium Calculation Method The enrollment method varies depending on occupation and income type. Workplace employees are classified as 'workplace subscribers,' with employees and employers sharing the insurance premium. Meanwhile, self-employed individuals and freelancers are classified as 'regionally insured subscribers' and bear the premium themselves. Full-time homemakers or students without income-generating activities can also enroll through the 'voluntary enrollment system' if they wish, and even if they have passed the mandatory enrollment age, they can use 'voluntary continued enrollment' to fulfill or extend their pension subscription period.

Insurance premiums are calculated based on the subscriber's reported or verified income. For employees, it is based on their salary, and for regional subscribers, it is based on income from business, labor, or rent, determined within the standard income range set by the National Pension system rather than the entire income.

■ National Pension System Changes Starting This Year The biggest change to the National Pension this year is that the insurance premium burden and the pension benefit structure have simultaneously begun to change. The long-maintained premium rate is being gradually increased, and the income replacement rate, which is used to calculate the old-age pension amount, has also been strengthened compared to previous plans. In other words, rather than simply paying higher premiums, the system has been reformed in a direction that simultaneously strengthens the function of guaranteeing income in old age.

■ Pension Receipt Timing and Strategy by Year of Birth The timing of receiving the National Pension differs depending on the year of birth. Those born earlier can receive it from a relatively young age, but as generations progress, the normal old-age pension starting age becomes later, so individuals must check their own benefit start point in advance.

• It is not mandatory to receive the pension starting from the normal receipt point. Flexible choices are possible depending on economic circumstances and retirement plans.
• Early Old-Age Pension: The pension start date can be moved up, but the monthly amount received is reduced, and this reduction applies for the long term.
• Deferred Pension: If receipt is delayed, the monthly pension amount increases for the delayed period. This is a useful option for those with sufficient other retirement income.

If the minimum subscription period is not met, the Old-Age Pension cannot be received. If the requirements are insufficient, payments must continue; if that is also difficult, the premiums paid so far can be returned in the form of a lump-sum refund.

• *■ How to Increase the Receipt Amount? Fulfilling the Subscription Period is Key**
• The National Pension receipt amount is determined by the 'subscription period' and 'income during the subscription period.' If you were unable to pay premiums in the past due to financial circumstances, you should not miss out on systems that can compensate for this and increase your future pension amount.
• Retroactive Payment System: Premiums incurred during the exemption period due to unemployment or business closure are paid later to restore the subscription period.
• Re-payment of Lump-Sum Refund: If you have a history of receiving a lump-sum refund in the past, you can pay it back to restore your subscription period.
• Credit System: Upon the occurrence of socially recognized reasons such as childbirth, military service, or unemployment, a certain period is recognized as a National Pension subscription period, or the premium burden is supported.

■ Prepare for Retirement with Online Application and Estimated Pension Inquiry Pension applications can be easily made online and via mobile, in addition to visiting a National Pension Service branch, and it is also possible to change the payment account receiving the pension. However, the required documents differ depending on the type of pension or family relationship, so you must check your own requirements before applying.

It is inappropriate to estimate your old-age pension based solely on the 'average receipt amount' of the National Pension. The actual amount received varies greatly depending on the individual's subscription history, income, and pension start date. By using the National Pension Service's 'Estimated Pension Inquiry Service,' you can check the amount you can expect to receive in the future based on your current subscription history, making it an excellent starting point for retirement preparation.
