Both Tax Expertise and Information Security, Fully Covered

Consider what kind of data a tax office handles, and information security stops being optional

Bookkeeping Involves Extremely Sensitive Information

Sales and purchase records, bank transaction history, even personal data like resident registration numbers and account numbers — tax offices exchange a business's most sensitive data every month. Handling this data without an understanding of information security is itself a risk.

IT specialists and information security experts work alongside our team
We understand and communicate in the language of Gasan Digital Complex IT companies' cloud and development environments
We manage access permissions and security procedures throughout data transmission and storage

Why This Matters Even More for IT Companies

Many of our IT and startup clients in Gasan Digital Complex are themselves highly sensitive about information security. If a tax office doesn't share that sensibility, communication itself becomes difficult. Tax103 brings both tax expertise and a team that understands how the IT industry handles data and speaks its language.

Why Choose a Local Tax Accountant

  • Fast response — able to visit in person right away when a tax audit or urgent filing issue arises
  • Local market knowledge — familiar with Gasan Digital Complex's leasing structures and Geumcheon-gu's local tax reductions (such as whether a location is outside the Overconcentration Control Zone)
  • Real-time communication — always reachable by KakaoTalk and phone, close enough to hand-deliver documents in person

※ In-person consultations are by appointment only. Remote consultations (phone, video call, KakaoTalk) are always available.
