Hometax Guides
Who this guide is for
- Foreigners trying to access Hometax for the first time
- Freelancers preparing May filing

Quick Answer
Foreigners often need Hometax access to file tax, check refund status, pay tax, or issue tax certificates. Sign-up usually depends on identity verification, foreigner registration information, and an available authentication method. Because login methods and screens can change, check official Hometax instructions when creating your account.
Key points
- Hometax access is often the first practical barrier.
- Identity details should match official registration records.
- Authentication options may change over time.
- Do not share login credentials with untrusted people.
Step-by-step explanation
Why does Hometax access matter?
Hometax is the main online tax portal used for many Korean tax tasks. For foreigners, it can be needed for income tax filing, refund checks, tax payment, certificates of income, tax payment certificates, and reported income review. Even if an employer handles year-end settlement, you may still need Hometax later for documents.
The hardest part is often not the tax concept but login setup. Names, registration numbers, mobile phone identity records, and authentication methods must line up. If one detail differs, the system may reject access or fail verification.
What should you prepare before signing up?
Prepare your foreigner registration information, the spelling of your name as used by Korean institutions, and any authentication options available to you. If you have a Korean mobile phone under your own name, it may help with verification. If not, check current Hometax guidance or ask the tax office what alternatives are available.
| Item | Why it helps |
|---|---|
| Foreigner registration details | Used for identity matching |
| Name spelling | Korean systems can be sensitive to spacing and order |
| Authentication method | Needed for login or certificate issuance |
| Contact details | May be used for alerts or verification |
What should you do after creating access?
After you can log in, confirm that basic records appear as expected. Do not change or submit tax data unless you understand the purpose of the screen. If your goal is filing, continue to the Hometax filing procedure. If your goal is a document, use the income certificate procedure.
Menu names and screen layouts may change. Always check official Hometax or National Tax Service information before relying on any navigation path.
Documents you may need
- Foreigner registration card information

Common mistakes
- Using a name format that does not match registration records

- Sharing authentication credentials
- Assuming every Hometax screen has English support
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. This site explains general patterns only and cannot review your personal facts.
