Scholarship and Research Stipend Tax in Korea
Visa & Tax
Who this guide is for
- International students receiving Korean scholarships
- Graduate students paid as research or teaching assistants
- Foreign professors, postdoctoral researchers, and visiting scholars
- Universities and laboratories documenting stipends and grants
Quick Answer
A payment called a scholarship or stipend is not automatically tax-free in Korea. Classification depends on who paid it, what it covers, whether the recipient must teach, research, or provide services, and whether Korean law or a specific tax treaty exempts it. Tuition support, living support, wages, research compensation, and expense reimbursement should be separated.
Key points
- Read the award terms and service obligations, not only the payment label.
- Tuition paid to a university differs from cash paid for work.
- Teaching, laboratory, or research duties can create compensation income.
- Student, trainee, teacher, and researcher treaty articles vary by country.
- Visa permission and tax exemption are separate questions.
Step-by-step explanation
Split the award into components
List tuition paid directly to the school, mandatory fees, books, travel, insurance, living allowance, expense reimbursement, and compensation for duties. One award can contain several tax categories. Ask the university for the Korean payment classification and any withholding statement.
Look for a service requirement
Hours, deliverables, supervision, teaching, laboratory work, intellectual-property terms, or continued payment conditioned on work can point toward compensation. Reimbursement requires a business or academic purpose and supporting receipts. An unrestricted living payment needs its own classification rather than being treated as wages by default.
Check the exact treaty
Some treaties have student, trainee, teacher, professor, or researcher articles. They may protect payments from abroad, named grants, limited local earnings, or qualifying teaching and research for a stated period. Nationality alone is insufficient; confirm prior residence, institution, purpose, amount limits, and duration.
Match tax and immigration records
Confirm that the university’s payroll report, Hometax data, visa work permission, bank receipts, and award documents tell the same story. If a payment was misclassified or withholding was omitted, resolve it before relying on a year-end certificate or May return.

- Scholarship or grant award letter
- University tuition statement
- Research or teaching assistant contract
- Payroll and withholding statement
- Expense reimbursement policy and receipts

Common mistakes

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.

FAQ
Are scholarships tax-free in Korea?
Some education support may be non-taxable or outside taxable income, but cash tied to services can be wages or another income type. Review the award and duties.
Is a research assistant stipend taxable?
It may be taxable if it compensates research, teaching, or other services. The payer's classification, contract, withholding, and actual duties should agree.
Can a tax treaty exempt a student or researcher?
Possibly. Treaties differ in covered grants, overseas remittances, employment amounts, research purpose, institution, and time limits, so use the exact treaty.
