Starting in 2026, changes to the National Pension insurance rates mean that both employees and employers must carefully check the changes in their monthly deductions. Many employees sigh every time they receive their pay stubs because the taxes and insurance premiums deducted are often more than they expected. In reality, social insurance premiums, which are deducted as a fixed amount every month, hit our wallets harder than income tax. For example, an employee with an annual salary of 50 million KRW has a significant amount withheld for National Pension and health insurance, making prior calculation essential. In this article, we will take a detailed look at the newly changed rate standards for this year, the precise calculation methods, and practical alternatives for saving on taxes.

2026 Four Major Insurance Rate Changes: Calculation Methods and Tax-Saving Tips
1. Changes to the Four Major Insurance Rates in 2026
The National Pension insurance rate applied from this year has moved away from the previous method, with the employee’s share increased to 4.75 percent. In the past, employees and employers each bore 4.5 percent, but starting this year, the employee’s portion has increased slightly due to legislative amendments. While this change is an unavoidable measure to prevent long-term fund depletion, it inevitably increases the perceived burden for those receiving monthly salaries. In fact, when you look at your pay stub, a significant portion of your total salary is deducted, including not just the National Pension but also health insurance, long-term care insurance, and employment insurance. Therefore, it is important to understand in advance exactly which items are increasing and by how much from your total salary in order to set your household budget. These rate changes are not just a tax issue but a core factor that directly determines your monthly take-home pay. If you are an employee, you should pay close attention to the legislative amendments announced at the beginning of each year and recalculate your expected take-home pay. Especially this year, with various fees and inflation overlapping with the National Pension changes, protecting your real income is more urgent than ever. When you talk to colleagues, the reason complaints arise about the large monthly deductions is precisely this. Only those who know the exact figures and take action can protect their assets more wisely than others.
With the increase in the National Pension rate this year, the employee’s burden has changed to 4.75 percent, directly impacting monthly take-home pay.
2. Why Your Pay Stub Differs from Online Calculators
It is very common for people to enter their total salary into an online calculator and be shocked when the result differs from their actual pay stub. The main reason for this discrepancy is that tax-exempt items, which are not subject to taxes or insurance premiums, are excluded. For example, meal allowances and commuting subsidies are included in the total monthly salary but are excluded from the insurance premium calculation base. Therefore, when using a calculator, you should accurately subtract tax-exempt amounts rather than simply entering your total annual salary to match the actual deductions. Additionally, because there are upper and lower limits for the standard monthly income, calculations for high-income or low-income earners may differ from simple percentage calculations. The company’s payroll date and whether you joined or left mid-month also apply pro-rata calculations, creating unexpected differences in amounts. People who are new to a job or have recently changed companies often misunderstand that their salary is too low because they are unfamiliar with this settlement system. If you want to know the exact amount, the most reliable method is to directly ask your HR department about tax-exempt items and applicable rates.
The reason calculation results differ from actual pay stubs is due to the application of tax-exempt allowances, income limits, and pro-rata calculation methods.
3. Freelancers and the Truth About the 3.3 Percent
It is common to find cases where people working part-time in kitchens or doing simple tasks sign freelance contracts for convenience, with only 3.3 percent deducted. From the employer’s perspective, this is a preferred method as it saves the hassle of complex social insurance enrollment procedures and the cost of bearing half the burden. However, if you have fixed working hours and receive instructions from the company, you are clearly an employee with potential legal violations. This can lead to damages such as not receiving severance pay when leaving the company or being unfairly denied unemployment benefits. In reality, many businesses that uniformly treated all employees as freelancers have later faced heavy fines or corrective orders for violating the Labor Standards Act. From the worker’s perspective, while the 3.3 percent deduction may seem like you are earning more money in the short term, it is a loss in the long run. If you are not enrolled in the Four Major Insurances, you will not receive National Pension benefits when you get older and will not be protected during unemployment. Therefore, when signing a contract, you must carefully consider whether you are truly an independent business owner or a worker protected by the Labor Standards Act.
Illegally treating all employees as freelancers to deduct only 3.3 percent leads to future legal disputes and the loss of welfare benefits.
4. The Dureunuri Support System for Small Businesses
Many small business owners lose sleep over the increasing insurance premium burden when hiring their first employee. If you run a small business with fewer than 10 employees, you should actively utilize the Dureunuri Support System, which refunds a portion of insurance premiums from the government. This system supports up to 80 percent of the Employment Insurance and National Pension costs borne by newly enrolled low-wage workers and their employers. However, to receive support, you must meet the condition that your previous year’s property tax base or comprehensive income does not exceed a certain standard. When you talk to other business owners, surprisingly many do not even know this beneficial system exists and fail to apply in time. By carefully checking the conditions and submitting an application to the local Workers’ Compensation and Welfare Service or National Pension Service, you can significantly reduce your fixed monthly expenses. This is the most reliable government support that allows you to take care of your employees’ welfare while simultaneously relieving your financial pressure. If you qualify for support, do not miss the opportunity to apply and use it as a chance to improve business efficiency.
Small businesses with fewer than 10 employees can receive up to 80 percent of Employment Insurance and National Pension burdens refunded through the Dureunuri Support System.
5. The Reality of Personal Bankruptcy and Unpaid Four Major Insurance Premiums
There are people who have received a personal bankruptcy or discharge decision due to business difficulties but continue to suffer from dunning notices for previously unpaid insurance premiums. Many people think that all debts disappear upon receiving a bankruptcy discharge, but unpaid social insurance premiums often do not disappear easily. In particular, National Pension and health insurance premiums have a nature similar to taxes paid to the state, unlike general private debts, making the processing procedure difficult. Even if you receive a discharge decision, if you receive severe dunning notices, you must follow the exact relief procedures through legal experts or consultations with the public corporation. People going through this situation often complain of extreme mental distress due to daily dunning calls and garnishment notices. Rather than worrying alone, you should learn systematic preparation methods and file objections with the responsible agency or apply for installment payment adjustments. To start a new life after bankruptcy, you must transparently organize your past unpaid records and find legal reduction systems. More important than the judgmental stares of those around you is securing the legal safety net that protects your rights and allows you to stand up again.
6. Smart Tax-Saving and Future Preparation Strategies
To reduce monthly insurance premiums and taxes while preparing for a stable future, you must actively utilize various financial products and systems. For example, managing assets through pension accounts can reduce the burden of comprehensive income tax and health insurance premiums, as a certain percentage is tax-exempt. It is also a smart way to reduce expenses for employees to claim tax deduction benefits during year-end settlement or comprehensive income tax filing. Instead of simply trying to avoid payments, you need the wisdom to find legal tax-saving routes rather than exploiting loopholes. Going forward, there is a high possibility that related rates and support systems will continue to be revised and changed according to economic environment shifts. The habit of carefully reviewing your monthly pay stubs and periodically checking amended laws will serve as a sturdy shield protecting your assets. We recommend that you re-examine your financial status based on the calculation methods and support benefits learned today. Small concerns and actions will become the fastest path to creating a prosperous and stable future.
