Leaving Korea Tax Checklist for Foreigners

Who this guide is for

• Foreigners preparing to leave Korea
• Former employees and freelancers checking tax records
• People who may need Korean documents after departure
• Foreigners expecting a tax refund

Key points

• Hometax and Korean banking access may become harder after departure.
• Download important tax documents before your phone number or account changes.
• Confirm whether year-end settlement or May filing still needs review.
• Keep employer and payer contacts in case records are missing later.

Step-by-step explanation

Why tax planning matters before departure

Leaving Korea can make simple tax tasks harder. You may lose access to Korean phone verification, close a bank account, change address, or lose contact with an employer or payer. Hometax may still be available, but practical access can become more difficult from abroad.

Before you leave, spend time checking tax records, refund status, payment history, and documents you may need later. This is especially important if you had freelance income, multiple employers, 3.3% withholding, unpaid tax notices, or a visa process that may require Korean income proof in the future.

Departure tax checklist

Tax refund, pension, and health insurance are different

Foreigners often use the word “refund” for several things. A Korean income tax refund is different from a national pension lump-sum refund or a health insurance adjustment. Each has a separate system, eligibility rule, and contact channel.

This guide focuses on tax records. If you are also checking pension or insurance, use official pension and insurance sources and keep those records separate from Hometax documents.

What to do if you already left Korea

If you already left, start by checking whether you can still access Hometax. Then contact your former employer, payer, or tax office if records are missing. If payment is needed, verify the tax type and official payment route. Avoid sending money through informal channels unless official instructions clearly support the method.

Final pre-departure habit

Make a simple folder with PDF copies of income certificates, tax payment certificates, withholding receipts, filing results, and payment confirmations. Add your employer and payer contacts. That folder can save hours later if a bank, immigration office, tax office, or future employer asks for Korean records.

Documents you may need

• Hometax login method
• Withholding receipts
• Certificate of income
• Tax payment certificate
• Refund bank account details
• Employer or payer contact details
• Pension and insurance records if relevant

Common mistakes

• Closing Korean access before downloading records
• Assuming a refund will arrive without checking bank details
• Leaving without payer contact information
• Confusing tax refund with pension refund
• Ignoring local income tax or unpaid notices

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.
