How do I register a security card for issuing electronic tax invoices?

To register a security card for issuing electronic tax invoices, you generally need to visit a local tax office. Here's a breakdown of the process:

1. Visit a Tax Office: Go to the nearest tax office (세무서) and visit the civil service office (민원봉사실).
2. Submit Application: Fill out the 'Application for Electronic Tax Invoice Security Card User' (전자세금계산서 보안카드 사용자 신청서).
3. Required Documents:
   • For individual business owners: Your ID card and business registration certificate.
   • For corporate business owners: Your ID card, business registration certificate, and a corporate seal certificate (issued within the last 3 months).
   • If applying through a representative: A power of attorney, the representative's ID card, and the corporate seal certificate (for corporations).
4. Receive Security Card: The security card will be issued on the spot after your documents are verified.
5. Register on Hometax: Log in to the Hometax website (www.hometax.go.kr), navigate to the electronic tax invoice section, and register your security card under the 'Authentication Method Registration/Management' menu.

Important Notes:

• The security card is issued free of charge and does not have an expiration date, unlike a joint certificate (공동인증서).
• If you lose or damage the card, you will need to visit a tax office again for a re-issuance.
• If there are changes in the business owner or the business is closed, a new card may need to be issued.
• Keep your security card safe to prevent unauthorized use.
