Before you start

What you need

Steps

  1. Step 1: Confirm the requested certificate

    Ask whether the institution needs a certificate of income, tax payment certificate, withholding receipt, or another document.

  2. Step 2: Log in to the official service

    Use Hometax, Sontax, or another official channel currently available for certificate issuance.

  3. Step 3: Choose the certificate period

    Select the year or period requested. If the latest year is not available, ask the requesting office what alternative is accepted.

  4. Step 4: Issue and review the document

    Check your name, period, and income details before submitting it to another institution.

What to check before submitting

What if the certificate is blank or incomplete?

A certificate usually reflects income reported through official channels. If expected income is missing, the cause may be timing, payer reporting, income category, or a wrong period selection. Ask the payer for a withholding receipt or correction path, and confirm with the tax office if needed.

For visa extension, do not assume the office will accept a different document. Requirements can vary by visa type and office practice, so verify the list before submitting.

FAQ

Can foreigners get a certificate of income in Korea?

Many foreigners can request income certificates through official channels when income has been reported, but available records depend on the period and reporting status.

No. A certificate of income shows reported income, while a tax payment certificate relates to tax payment status. Confirm the exact document requested.

What if the certificate does not show my expected income?

Check the selected year, payer reporting status, and income category. If the issue affects a deadline, ask the requesting office or tax office what alternative is accepted.
