Detailed explanation

What is year-end settlement?

Year-end tax settlement is the annual process where an employer reviews salary income, withholding, and eligible documents to adjust the employee’s wage tax position. For many foreign employees, this is the main tax process they experience in Korea. It is common at companies, schools, and organizations that pay salary income.

The process can feel automatic, but it still depends on correct records. Your employer may ask for forms, certificates, or confirmation of personal information. If you had only one salary job and no unusual income, the employer process may be enough. If you had multiple employers, freelance income, business income, or overseas income, you should review whether separate filing is needed.

What documents are usually involved?

Your employer may provide instructions and deadlines. You may need identity details, proof of income from a previous employer, or deduction-related documents if you are claiming items allowed under current rules. Foreigners should avoid guessing about deductions. Rules may change, and some items may require specific Korean documents or eligibility.

Agree the income year and the payroll timetable

The NTS wage-income guidance describes settlement for continuing employees when the following February’s wages are paid, and settlement when wages for the month employment ends are paid for employees who leave their job during the year. Your employer needs documents before it completes that calculation, so ask for its submission deadline rather than using the payroll month as your personal document deadline.

The linked English Easy Guide covers 2025 income and was published in January 2026. It is not a 2026-income deductions checklist. For settlement of 2026 pay, check the applicable year’s official instructions and your employer’s document request before choosing a deduction or special treatment.

Send payroll a complete question, not just a document bundle

Use this worksheet to identify missing information. The questions are preparation prompts, not a claim that every employee must submit the same documents.

A file appearing in a simplified-data download does not itself resolve eligibility for a claim. Flag uncertain items before submitting them. Payroll should be able to tell you what it included, what it excluded, and which evidence it relied on.

Read the final receipt before treating the process as complete

Ask for the wage and salary withholding receipt, 근로소득 원천징수영수증. Compare the employer, identity details, income year, pay, and included employment periods with your records. In the national-tax calculation, distinguish final tax (결정세액) from prepaid withholding (기납부세액) and the balance (차감징수세액).

Simplified arithmetic example: final national tax of KRW 300,000 minus KRW 420,000 already withheld gives a KRW 120,000 refund balance. If final tax were KRW 500,000 instead, the balance would be KRW 80,000 to pay. These assumed final-tax figures illustrate the direction of the calculation; they do not establish deductions, a tax rate, or a local-tax amount for a reader.

Compare the adjustment with your payslip and ask payroll about any unexplained difference. Store the final receipt with the documents you submitted. For a visa or bank request, check whether the recipient wants this receipt or a separate certificate of income; the documents serve different purposes.

What if the settlement is wrong or incomplete?

Ask your employer’s payroll or HR contact first. If the issue relates to income outside that employer, Hometax records, residency, or treaty questions, consider asking a tax professional. Keep copies of messages, receipts, and final documents. If you later need a certificate for visa extension, the income shown in official systems may matter more than informal payslips.

Read the income tax filing guide if you have non-salary income, and the income certificate procedure if your next goal is paperwork.

Documents you may need

• Employer request forms
• Salary withholding receipt
• Eligible deduction documents if applicable
• Previous employer income documents after job changes
• Hometax certificate access

Common mistakes

• Assuming the employer sees income from every payer
• Missing the employer's document deadline
• Not saving the final receipt
• Treating settlement as personal tax advice

When should you ask a tax professional?

Ask a qualified tax professional if you have income from several countries, business income, unclear tax residency, treaty questions, missing documents, late filing concerns, or a visa situation that depends on tax records.
