November 10 Withholding Tax Deadline: What Foreign Business Owners in Korea Need to Know
November 10 Withholding Tax Deadline: What Foreign Business Owners in Korea Need to Know
“I paid employees or freelancers in Korea last month. Do I have a tax deadline today?”
If you operate a business in Korea and paid certain types of income in October, November 10, 2026 may be an important withholding tax deadline.
Foreign business owners are generally subject to the same Korean withholding tax obligations as Korean business owners.
What Is Due on November 10?
For monthly withholding taxpayers, Korean tax withheld from certain income paid in October 2026 generally must be reported and paid by:
November 10, 2026
This may apply when your business paid income such as:
Employee salaries
Certain freelance or independent service fees
Other payments subject to Korean withholding tax
Local income tax related to the withholding may also need to be reported and paid.
Are Employees and Freelancers Taxed the Same Way?
No.
Employee salaries are generally subject to wage withholding rules based on Korea’s payroll withholding system.
For certain independent personal-service business income, 3% national income tax plus 0.3% local income tax — commonly referred to as 3.3% withholding — may apply.
However, not every person called a “freelancer” should automatically be taxed at 3.3%.
The correct treatment depends on the actual nature of the work and the type of income being paid.
What If You Paid a Foreigner or Someone Overseas?
Additional review may be necessary.
Payments to a nonresident individual or foreign company can be subject to different withholding rules depending on:
The type of income
Whether the recipient is a Korean tax resident or nonresident
Whether the recipient has a business presence in Korea
The applicable tax treaty
The nature of the services provided
Therefore, applying the usual domestic withholding rate without checking the recipient’s tax status may result in an incorrect filing.
Does Every Business Have a November 10 Deadline?
Not necessarily.
Some eligible businesses that have been approved for semiannual withholding tax payment follow a different schedule.
This is why business owners should confirm whether they are monthly or semiannual withholding taxpayers rather than assuming the same deadline applies to everyone.
What If You Miss the Deadline?
If you were required to report or pay withholding tax by November 10 but missed the deadline, it is better to review the issue promptly.
Late reporting or payment may result in additional tax or penalties depending on the circumstances.
The amount withheld, the type of income, the recipient’s tax status, and whether the business qualifies for a different filing schedule can all affect the correct treatment.
If you are unsure whether your October payments created a withholding tax obligation, consulting a qualified Korean tax professional can help you determine what needs to be reported and how to correct any missed filing.
