🏦 Banking Essentials for Foreign Founders in Korea

Starting a business in Korea? Setting up your corporate banking is one of the most critical hurdles. The good news is that with the right documents and an in-person visit, it is all doable in half a day! ⏱️✨

(⚠️ Note: Please be advised that the specific procedures and requirements mentioned below may vary depending on the bank and branch you choose. It is highly recommended to consult with your bank directly before visiting.)

Here are the three core tasks you need to complete:

💼 Step 1. Corporate Account (법인계좌)

• Expect Limits at First: Banks are generally cautious about opening accounts for newly incorporated entities. You should expect to receive a "Limited Account" (한도계좌) initially. 📉What does "Limited" mean? It refers to strict limits on the amount of money you can transfer per transaction and per day.
• What does "Limited" mean? It refers to strict limits on the amount of money you can transfer per transaction and per day.
• How to Lift the Limit: You can transition to a normal account by keeping the account active for 30+ days, paying taxes through the account, or providing solid proof of business activities, such as export/import invoices or signed contracts. 📈

💳 Step 2. Cards & OTP

• Check Cards (체크카드): These can be issued immediately. It is often recommended to sign up for a regular savings deposit at the same time.
• Credit Cards (신용카드): These are harder to get for new startups. Typically, you will need to open a time deposit and provide it as collateral (pledge). 🔒
• OTP (One-Time Password): Make sure to get a physical OTP device issued! It is absolutely mandatory for the next step. 🔑

📜 Step 3. Joint Certificate (공동인증서)

• The Golden Key: You must have the OTP issued first to enable the issuance of a Corporate Joint Certificate (공동인증서) via the bank's website. 💻
• Paid Version is Mandatory (But Choose Wisely): To perform business-critical tasks like issuing Tax Invoices (세금계산서), you must use a paid certificate. 💸4,400 KRW/yr Version: This is sufficient for most standard business operations, including tax invoicing and HomeTax duties. ✅110,000 KRW/yr (General Purpose): You do NOT need this expensive version unless you plan to participate in government bidding (Narajangteo). For daily corporate tasks, the 4,400 KRW version is perfect.

• Why it's Mandatory: This certificate is the primary method of authentication for all filings on HomeTax (홈택스).
• No Certificate = No Online Taxes: Without it, you cannot file VAT, corporate tax, or withholding tax online. 🚫

📑 Checklist: Required Documents

Ensure you have the following documents ready before your bank visit:

• 🛂 CEO Passport & Alien Registration Card (ARC/거소증)
• 📋 Shareholder Register (주주명부)
• 🪇 Corporate Seal (법인인감도장)
• 📄 Certificate of Corporate Registration (법인등기부본)
• (Optional but helpful) Business Registration Certificate (사업자등록증)

💡 E-chon Tip: Never Walk In Blind!

Always contact the branch officer via phone or email first! Confirm the exact list of required documents and book a specific time slot. Requirements for foreign founders can vary significantly between different banks—and even between different branches of the same bank. A 5-minute call can save you 5 hours of frustration! 📞✉️
