Sorted by priority

Residency transition, resident-period overseas income, Article 57-style foreign tax credit, FBAR threshold checks, and local income tax are preserved. This English calculator calls the Korean page feature lib directly. The UI is translated, but the numbers come from the same pure calculation path instead of a generic value-times-rate stub.

Returning expatriate tax settlement calculator

This English guide translates the Korean returning-expatriate settlement article for people who move back to Korea after a long overseas assignment, study period, permanent-residency period, or foreign business activity. The calculator keeps the Korean residency-transition, income apportionment, foreign tax credit, FBAR, overseas property, and social-insurance logic.

Residency transition and income apportionment

Korean tax residency can change when a person has an address in Korea or stays in Korea for 183 days or more during the tax year. The Korean guide therefore starts with the 183-day residency test, address registration, family reunion, and job-return facts before deciding when the taxpayer changes from non-resident to resident.

The key point is not whether all overseas income is taxed automatically. Overseas income is apportioned between the non-resident period and the resident period, while Korea-source income is included under Korean rules. That split is why the calculator asks for return date, prior Korea stay days, domestic income, and overseas income separately.

Foreign tax credit and double taxation

Foreign income tax and foreign local tax paid on resident-period overseas income can be compared against the Korean foreign tax credit limit. The calculator also compares credit treatment with expense-deduction treatment so the user can see which method leaves less Korean tax.

When foreign tax exceeds the credit limit, the Korean guide explains the five-year carryforward concept. The English content preserves that planning point because returning in the middle of a year can leave only part of overseas income in the Korean resident period.

Overseas accounts, property, and social insurance

Korea has a foreign financial account reporting regime. The guide uses the KRW 500 million foreign financial account threshold and checks bank, securities, insurance, pension, and crypto balances. Missing that filing can create penalty exposure that is separate from the income-tax calculation.

If overseas real estate is still held or will be sold, the timing before or after return can change Korean capital-gains taxation and foreign tax credit use. The calculator also gives a pension and health-insurance estimate because returning taxpayers often need both tax and insurance cash-flow planning.
