Korean tax residence can arise from domicile or a qualifying period of residence. Family, occupation, assets and living circumstances can establish domicile before a day threshold is reached.
The rule
The recorded-day total covers only the presence period described on this page. Review the current rules for residence spanning tax years and the separate domicile criteria before interpreting it.
Counting the days
Recorded arrival and departure dates count once. Missing travel history, other eligibility conditions and treaty outcomes are not calculated.
- Choose the date through which you want to count, then add your recorded visits.
- Use the counting convention above. Overlapping recorded dates in the relevant region are counted only once.
- Read the result alongside the conditions. Missing records and other eligibility requirements are not inferred from a total.
Examples

Exceptions & edge cases
Residence generally follows a domicile or 183 days of residence. Family, occupation or assets can establish a domicile sooner. From 2026, 183 consecutive days spanning two tax years can also make you resident; this calendar-year counter does not test that route.
Use the official reference for the full conditions and any changes since the source review date shown on this page.
Common misconceptions
“A count below the day threshold settles tax residence.”
A recorded-day total is one component. Review the separate conditions and exceptions described on this page.
“The window follows the latest twelve months.”
This counter uses the calendar year. A rolling window and a calendar year can produce different totals.
