South Korean Students: U.S. Treaty Rules for Study and Wages
What eligible South Korean students should check about the U.S. treaty’s student article and limited services income benefit.
The U.S.–South Korea treaty can exempt specified amounts for eligible students temporarily in the United States. The IRS summary includes qualifying amounts received from abroad, certain grants, and up to $2,000 of personal-services income each tax year for a limited period. The exact treaty conditions control.
Check when and why you came to the U.S.
The IRS describes a benefit for an individual resident in South Korea on arrival who is temporarily in the United States primarily for education, training, or qualifying grant-funded study or research. The student article generally limits the exemption period to five years. Prior visits and status changes can matter.
A South Korean passport alone does not prove treaty residence. Review the treaty article, program purpose, and dates before excluding any amount.
Separate payments by category
Amounts from abroad for maintenance or education are different from U.S. wages. The IRS summary gives a separate annual limit for eligible personal-services income. A grant may have its own conditions. Use W-2, 1042-S, scholarship letters, and pay records to distinguish the categories.
On Form 1040-NR, treaty claims must align with income reporting and Schedule OI answers. Do not simply subtract the maximum treaty amount from total income without showing which eligible payments it covers.
Consider state returns too
A federal treaty exemption does not automatically determine state tax treatment. Review the state where you studied or worked, especially if state income tax was withheld from a W-2.
What to do next
Apply the student article only to eligible amounts and years, and document the claim on the right return.
