🇺🇸 미국 주식 투자를 위한 해외 LLC 활용 방법?

It is a smart move to look for ways to protect your savings in a more stable environment. Using a US LLC for investment purposes is a common strategy, though it does add a few layers of paperwork compared to a personal account.
Since you already have the LLC and a Chase bank account, you have already cleared the hardest hurdles. Here is the ELI5 (Explain Like I'm Five) process for moving into the stock market.

1. The Correct Process (Step-by-Step)

Step A: Choose an Entity Account
When you sign up for a brokerage, you must not select a Personal or Individual account. You must select Entity, Organizational, or Corporate account.

Why? The account must be in the name of your LLC, not your name. The brokerage will ask for the LLC’s Employer Identification Number (EIN).

Step B: Prepare Your Golden Documents
Brokerages are very strict with foreign-owned companies because of Know Your Customer (KYC) laws. You will need:

Articles of Organization: The paper from the state where you formed the LLC.

Operating Agreement: This is crucial. It must clearly state that you are the Authorized Signer or Manager with the power to trade stocks.
EIN Confirmation Letter (CP 575): The letter the IRS sent when you got your tax ID.

W-8BEN-E Form: This is the tax form for foreign entities. It tells the IRS that your LLC is owned by a foreigner so they apply the correct tax rules (and avoid double taxing you if a treaty exists).

Step C: Link the Bank Account
Once approved, you will link your Chase Business account. Most brokers use ACH transfers (which are free and take 1–3 days) or Wires (which are instant but usually cost $20–$30).

2. Recommended Brokerages for Foreign-Owned LLCs
Not all brokers like working with foreign-owned LLCs. Some (like Robinhood or Vanguard) often require the owners to be US residents. Here are the big three for your situation:

Interactive Brokers (IBKR): Generally considered the best choice for international users. They have the most experience with foreign entities and offer access to global markets (London, Tokyo, etc.), not just the US.

Charles Schwab: Very reputable and has a dedicated Schwab One International division. They provide excellent service but the application for an LLC is usually a paper/PDF form rather than a 5-minute online click.

J.P. Morgan Self-Directed (Chase): Since you already bank with Chase, you can open an investment account directly through them. It is convenient because you can see your bank balance and stocks in the same app.

3. Common Pitfalls to Avoid

The Form 5472 Trap: This is the most dangerous part. Even if your LLC makes zero profit, as a foreign-owned LLC, you must file Form 5472 and Form 1120 with the IRS every year. The penalty for forgetting this starts at $25,000.

Estate Taxes: If a non-US person dies owning more than $60,000 in US assets directly (or through a disregarded LLC), the US can take up to 40% in Death Taxes. Many people use a Blocker Corporation or specific insurance to avoid this.

Withholding on Dividends: The US will automatically take 30% of any dividends your stocks pay out. If your country has a tax treaty with the US, you can lower this to 15% or 0% by
