How to Get a Certificate of Income in Korea
Tax Documents
Before you use this procedure
A certificate of income can often be issued through Hometax, Sontax, a tax office, or other official channels depending on the current system. Foreigners should confirm the exact document name, year, and issue method requested by the institution. Records shown on the certificate depend on reported income.
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
- Ask the requesting office for the exact document name.
- Confirm the year or tax period required.
- Check whether online issuance is accepted.
- Make sure your Hometax login works before the deadline.
What you need
- Foreigner registration information
- Hometax or Sontax access
- Printer or PDF saving option if available
- Request details from immigration, bank, employer, or school
Steps
-
Step 1: Confirm the requested certificate
Ask whether the institution needs a certificate of income, tax payment certificate, withholding receipt, or another document.
-
Step 2: Log in to the official service
Use Hometax, Sontax, or another official channel currently available for certificate issuance.
-
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.
-
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.
Common mistakes
- Issuing the wrong year
- Confusing income certificate with payment certificate
- Assuming payslips are enough
- Waiting until the visa appointment date
What to do if you are stuck
- Visit a tax office if online issuance fails.
- Ask your employer or payer if income is missing.
- Confirm whether the requesting office will accept alternative documents.
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.
Is a certificate of income the same as a tax payment certificate?
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.
