Short summary: A general step-by-step Hometax filing procedure for foreigners who need to review Korean income tax filing.

Before you use this procedure

Use this procedure as a general navigation map for filing income tax on Hometax. It does not decide whether you must file or what numbers to enter. Menu names and screen layouts may change, so always verify with official Hometax or National Tax Service information.

Important: Menu names and screen layouts may change. Always check the latest information on the official Hometax or National Tax Service website.

Before you start

What you need

Steps

  1. Step 1: Log in to Hometax

    Open the official Hometax website and sign in using an available authentication method. Confirm your identity information matches your foreigner registration records.

  2. Step 2: Find the income tax filing menu

    Look for the income tax or Global Income Tax filing area. The English wording may differ, and Korean menu names can change.

  3. Step 3: Review reported income

    Compare Hometax records with your own salary, freelance, and withholding records. Do not assume the system has every item.

  4. Step 4: Review, save, and submit only when confident

    Check the summary, payment or refund information, and any warnings. Save confirmation records after submission.

What to check before submitting

What should you review before pressing submit?

Before submitting, compare the Hometax summary with your own records. Look for missing payers, unexpected income categories, incorrect bank account details, and any warnings. If the page shows a payment amount, confirm how and when payment should be made. If it shows a refund amount, treat it as a system result that may still depend on review and processing.

If your case includes overseas income, treaty questions, business expenses, crypto, investment income, or unclear residency, this basic workflow may not be enough. Stop and get qualified help rather than guessing.
