Managing South Korean National Pension Contributions

Managing South Korean National Pension Contributions

by

Employees in Korea pay National Pension contributions through payroll, split equally with the employer, and foreign workers are generally covered too unless their home country does not cover Koreans. For 2026 the total rate is 9.5% of standard monthly income, or 4.75% from the employee and 4.75% from the employer, according to a Lockton briefing on the pension reform. When a foreign worker leaves Korea, a lump-sum refund may be available, but only for certain nationalities and visa types.

Who is covered, including foreign residents

The National Pension Service (NPS) publishes a guide for foreigners. It says foreigners aged 18 to 60 who live in Korea are covered on the same mandatory basis as Korean nationals. The exception is people from countries that do not extend pension coverage to Korean nationals, who are excluded. Whether your own nationality falls into that group is not something a general article can settle, so ask the NPS or your employer’s payroll staff, who will have it on record.

For employees, the NPS guide describes contributions as split equally between employee and employer, so the practical starting point is your payroll department.

How much is deducted

The contribution is a percentage of your reported standard monthly income, not of every won earned. Lockton reports that the total rate rises by 0.5 percentage points a year starting on 1 January 2026 until it reaches 13% in 2033, shared equally between employer and employee. The schedule it gives runs as follows:

  • 9.5% total from 1 January 2026 (4.75% each)
  • 10.0% from 1 January 2027 (5.00% each)
  • 10.5% from 2028, 11.0% from 2029, 11.5% from 2030
  • 12.0% from 2031, 12.5% from 2032 and 13.0% from 2033

Lockton adds that the previous total rate was 9.0%, which is 4.5% each. Older guides, including some that are still online, quote the earlier 4.5% employee figure.

The Korean Tax Expert site, which summarises social insurance rates for employers, reports that the standard monthly income range was KRW 400,000 to KRW 6,370,000 until 30 June 2026 and KRW 410,000 to KRW 6,590,000 from July 2026. Because the contribution is based on a standard monthly income within a range, check your payslip to see which standard income figure your employer reports.

Reading your payslip

  1. Find the National Pension line and compare it with 4.75% of your standard monthly income.
  2. If the figure is different, ask HR which standard monthly income is registered for you, since it is not always identical to the current month’s pay.
  3. Check that the employer’s matching share is recorded; your side is the only part you see deducted.
  4. Note that health insurance, long-term care insurance and employment insurance are separate deductions with their own rates.

Lump-sum refund when leaving Korea

According to the NPS page on lump-sum refunds for foreigners, foreign insured persons qualify in three situations:

  • their home country extends comparable benefits to Korean nationals (reciprocity);
  • a bilateral social security agreement exists between their country and Korea; or
  • they hold E-8, E-9 or H-2 visas.

The page says that, as of June 2026, 50 countries take part through two routes: 24 through social security agreements and 26 through reciprocity. For some reciprocity countries there is a minimum contribution period, such as six months or one year, while others have none.

Applications can be made in person at an NPS office before departure, by post from overseas, or through an authorised agent. Documents named for an application made before leaving Korea are the application form, passport and alien registration card, proof of a bank account, and evidence of the departure date within one month. From overseas, documents need notarisation and consular attestation or an Apostille, with translations for foreign-language documents. The page also says an application must be made within five years of entitlement, and that travellers leaving through Incheon International Airport can receive the refund in 16 foreign currencies on the day of departure.

Agreements between countries

The NPS guide also describes social security agreements, defined as agreements with Korea that secure benefit rights by combining the insured periods in each country. If your home country has one with Korea, ask the NPS how your Korean contribution period can be counted. The guide says benefit claims are submitted to regional pension service offices, in person or by post through an agent, with passport copies, the application form and bank details.

Common mistakes and what to verify

  • Using an old rate. The employee share was 4.5% before 2026; confirm the current share on your payslip.
  • Assuming your nationality qualifies for the refund. Check the NPS list of reciprocity and agreement countries.
  • Leaving the country without applying and then missing the five-year window.
  • Applying from abroad without the required notarisation or Apostille.
  • Confusing the pension with other social insurance deductions.

Rules change: confirm with the official body

This is general information, not legal, tax or financial advice. Contribution rates, income limits, country lists and refund rules are revised over time. Confirm your own situation with the National Pension Service (nps.or.kr) before relying on any figure here, and speak to a qualified professional for personal planning.
