Rough estimate. Deposits made by December 31 count for that year, and early withdrawal of credited money can trigger a 16.5% other-income tax. Pension payouts assume age 55 or older.
What is the pension savings and IRP tax credit?

A share of what you pay into pension savings and IRP (retirement pension accounts) is deducted directly from that year's income tax. Unlike a deduction, your tax falls by the contribution times the credit rate regardless of your tax bracket. The 15% (or 12%) income tax credit plus 10% local income tax works out to 16.5% (or 13.2%).

  • Rate: 15% up to KRW 55 million of salary (KRW 45 million of total income if you have other income), 12% above
  • Limit: KRW 6 million for pension savings; KRW 9 million combined with IRP per year
  • ISA transfer: 10% of ISA maturity money moved into a pension account (up to KRW 3 million) raises the limit

16.5% applies to salary up to KRW 55 million (KRW 45 million of total income with other income), 13.2% above that. Pension savings alone is credited up to KRW 6 million, so the KRW 9M row assumes IRP fills the rest.

Before you contribute
  • Deposits made by December 31 count for that year. Allow a few days, as year-end transfers bunch up.
  • A small final tax means you cannot use the full credit, because it only refunds tax actually owed.
  • Early withdrawal can add a 16.5% other-income tax on credited contributions and earnings. Plan on receiving it as a pension from age 55.

How is the credit rate decided?
With salary only, it is 15% up to KRW 55 million of total salary and 12% above. With other income, it is 15% up to KRW 45 million of total income and 12% above. Adding 10% local income tax makes the effective refund rate 16.5% or 13.2%.
What do the KRW 6 million and KRW 9 million limits mean?
Pension savings is credited up to KRW 6 million a year, and pension savings plus IRP together up to KRW 9 million. Putting the full KRW 9 million in pension savings still credits only KRW 6 million, so the other KRW 3 million must go to IRP.
What if I move ISA maturity money into a pension account?
Money moved into a pension account within 60 days after the ISA term ends adds 10% of that amount (up to KRW 3 million) to that year's credit limit. This calculator counts the transfer as a contribution and credits up to KRW 9 million plus the extra limit.
What if my final tax is smaller than the credit?
The credit only refunds tax you owe, so any part above your tax before this credit is lost. Enter your expected final tax to see the income tax credit capped at that amount.
What is the deadline for the year's credit?
Deposits made by December 31 count for that year. Year-end transfers bunch up and may post late, so leave a few days of margin.
Is there a penalty for early withdrawal?
Withdrawing credited contributions and earnings as a lump sum or closing the account can trigger a 16.5% other-income tax. Pension payouts are available once conditions such as age 55 and five years since opening are met.
