Private Tutoring Income Tax in Korea for Foreigners

Who this guide is for

• Foreigners giving recurring private lessons
• Teachers paid 3.3% by academies or clients
• Online tutors working from Korea
• Foreign residents considering tutoring as side income

Key points

• Classify the real activity before applying a withholding label.
• Recurring independent lessons can be business income even without 3.3% withholding.
• Visa and education-law permission are separate from tax compliance.
• Track gross fees, platform deductions, refunds, and supportable expenses.
• Reconcile payer statements with the May income tax return.

Step-by-step explanation

Classify the actual relationship

The contract label is only a starting point. A tutor directed by one academy under its schedule and supervision may resemble an employee. A person independently offering recurring lessons to multiple students may have business income. A genuinely isolated lecture can fall into other income. Frequency, independence, control, and the commercial setup matter together.

Understand what 3.3% means

When a payer withholds 3% national income tax plus local income tax from qualifying business-service payments, the deduction is usually a prepayment. It is not proof that the classification is correct and it is not automatically the final liability. The tutor normally reconciles annual income, expenses, deductions, and prepaid tax through the applicable May filing.

Check permission outside the tax system

Immigration permission, private-tutoring rules, business registration, and tax reporting answer different legal questions. Paying tax does not authorize work that a visa prohibits. Before advertising or accepting students, confirm permitted activities with immigration and ask the competent education or local office whether a tutoring report or registration is required.

Keep a tutoring ledger

Record lesson date, student or payer, gross fee, refund, platform fee, withholding, and net receipt. Store agreements, schedules, and payment evidence. For expenses, preserve the business purpose and separate personal portions. A home, phone, computer, transport, or training cost is not fully deductible merely because tutoring occurs.

Reconcile before filing

Compare your ledger with Hometax payer submissions and withholding statements. Investigate missing or duplicated amounts. Report foreign-platform or overseas-client payments based on the applicable residence and source rules rather than assuming they disappear because the payer is abroad.

Documents you may need

• Lesson agreements and schedules
• Payer and student payment records
• Withholding statements
• Platform settlement reports
• Business or tutoring registration records
• Visa work-permission evidence
• Expense receipts and mileage or room-use support
• Annual Hometax income record

Common mistakes

• Treating every 3.3% payment as a final tax
• Assuming cash lessons do not need to be reported
• Using tax registration as proof of immigration permission
• Deducting personal living costs as tutoring expenses
• Reporting net platform deposits instead of reconciling gross revenue and fees

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.
