Korea Civil Service Pension Income Reduction Calculator — 30% to 70% of Income Above the Average Pension, Capped at Half

Korea Civil Service Pension Income Reduction Calculator — 30% to 70% of Income Above the Average Pension, Capped at Half

Earn money again while drawing a Korean civil service pension and part of the pension stops. Article 50(3) of the Public Officials Pension Act says that if a retirement or early pensioner has business or employment income amounts and their monthly average (monthly income) exceeds last year’s average pension, the excess is used to suspend 30% of it under 500,000 won, then 40%, 50% and 60% in steps, up to 900,000 won + 70% at 2 million won or more. The suspension can’t exceed half the pension. Re-appointment as an official, soldier or teacher, or taking an elected post, suspends the whole pension for that period (para. 1).

1. Excess = monthly income − last year’s average pension. Monthly income = the year’s income amount ÷ months with income.
2. Suspended: under 500,000 → 30% · 500,000–1 million → 150,000 + 40% · 1–1.5 million → 350,000 + 50% · 1.5–2 million → 600,000 + 60% · 2 million+ → 900,000 + 70%.
3. Capped at half the pension. Re-appointment or elected post: all of it.

Updates as you type. Monthly income = the year’s income amount (under 10,000 won not counted) ÷ months with income (Decree Art. 47(2)); won fractions dropped by us. The 2.5 million won average pension is our example, not the official figure — enter the published one. The suspension can’t exceed half the pension. Local council members and the 160% rule have special cases (Art. 50(1) proviso).

The steps join up at each boundary (500,000 → 150,000, 1 million → 350,000, 1.5 million → 600,000, 2 million → 900,000) (our sums). The Act defines the average pension as “retirement and survivor retirement pensions combined, divided by the number of recipients”, but the year’s actual figure isn’t in it, so the calculator holds our example of 2.5 million won.

When the whole pension stops — Art. 50(1)

TypeWhat the source saysWorth noting (ours)
Item 1Appointed as an official, soldier or private school teacher under this Act, the Military or Teachers’ Pension ActAll suspended during that service
Item 2Takes an elected public officeA local council member earning less than the pension has only that amount suspended (proviso)
Items 3–5Hired by a public body, local public enterprise or local funded body wholly funded by the state or a local governmentUnder 160% of last year’s average official base income, para. 3 applies instead (proviso)
DesignationThe Minister of Personnel Management designates them and publishes by 25 January each year in the Official Gazette (Decree Art. 46(5))Judged on the last 3 years’ average funding share

How monthly income is set — Decree Art. 47

TypeWhat the source saysWorth noting (ours)
Monthly income (2)The year’s income amount from 1 January to 31 December (under 10,000 won not counted) divided by the months income aroseThe tax-law “income amount”, not gross pay
Provisional (3)If it exceeds the average pension, a provisional suspension is set using last year’s average pension—
Data (4)Based on data from state bodies; if not available, the previous year or the one before—
Settlement (5)After the final income tax return the year’s suspension is fixed and the difference adjusted in later payments; an early adjustment can be requested with evidenceSettled after the May return, in effect (our gloss)

Three sums — our examples (average pension assumed 2.5 million won)

Example (ours)ExcessSuspension (our sums)
Pension 2.5 million, employment income amount 48 million a year (12 months)4 million − 2.5 million = 1.5 million600,000 + 0 = 600,000 a month; 1.9 million paid
Pension 2 million, 33 million (12 months)2.75 million − 2.5 million = 250,000250,000 × 30% = 75,000 a month; 1,925,000 paid
Pension 1.8 million, 96 million (12 months)8 million − 2.5 million = 5.5 million900,000 + 3.5 million × 70% = 3.35 million → cap 900,000; 900,000 paid

The National Pension stopped reducing pensions for an excess under 2 million won from 17 June 2026 (against its own A value), but civil service Art. 50(3) applies 30% from the first won of excess. The National Pension side is in National Pension reduction for working pensioners 2026.

Checklist

  • ☐ Is the new job an official, military or teaching post, or a wholly funded body?
  • ☐ The year’s business/employment income amount (after expenses or the employment deduction)
  • ☐ The average pension figure the Service uses that year
  • ☐ Report re-appointment or leaving within 10 days (Decree Art. 47(1))
  • ☐ A settlement difference may follow the income tax return

Questions that remain

Do pension, interest or rental income count?

Para. 3 names only the business income amount (Income Tax Act Art. 19(2)) and employment income amount (Art. 20(2)). Other kinds aren’t in this provision.

Where is the pension age?

The 60–65 table by retirement year and early pension rates are in civil service pension age calculator.
