Korean Branch and Representative Office Formation Counsel in New York

A company planning to sell products or services in New York typically needs a branch office or a separately incorporated subsidiary. A company still testing the market, or supporting an existing distributor, often starts with a representative office before committing to a revenue-generating structure.

Switching from a representative office to a branch, or from a branch to a subsidiary, requires new New York filings and can add federal tax steps. Fast-growing companies often plan for this conversion in advance.

Under Business Corporation Law Section 1304, a foreign corporation doing business in New York must file an Application for Authority with the Department of State. The filing requires a Certificate of Existence from the home jurisdiction dated within one year and a $225 statutory fee. Attorneys assisting with foreign business registration can confirm whether a representative office's activities cross the "doing business" threshold that triggers this filing.

A corporation doing business in New York without a Certificate of Authority cannot maintain a lawsuit or special proceeding in New York courts until it registers. It may still be sued during this period, and it remains liable for any state taxes that accrued while unauthorized.

Under Internal Revenue Code Section 884, a foreign corporation operating a US branch faces a branch profits tax of 30 percent on its dividend equivalent amount. This tax applies on top of the regular corporate income tax on effectively connected earnings. Attorneys handling international tax compliance can help structure US net equity to manage this exposure.

New York State imposes a corporate franchise tax under Tax Law Article 9-A on corporations doing business, maintaining an office, or deriving receipts in the state. New York City separately imposes its own Business Corporation Tax, so a Korean branch operating in Manhattan can face both taxes at once.

The United States-Korea Income Tax Treaty generally taxes business profits only when attributable to a permanent establishment. Activities limited to preparatory or auxiliary functions, such as market research or liaison work, typically fall outside the permanent establishment definition and may reduce or eliminate branch profits tax exposure.

New York's Secretary of State becomes the corporation's statutory agent for service of process once the corporation files its Application for Authority. Business Corporation Law Section 408 also requires a Biennial Statement every two years, confirming the corporation's current address for forwarding legal papers. A private registered agent is optional; firms managing corporate compliance and risk management often track these filings for their clients.

Corporate documents issued in Korea generally require authentication through apostille before New York agencies will accept them for filing. Missing or improperly authenticated documents commonly delay Certificate of Authority applications.

Banks generally require proof of New York registration, beneficial ownership information, and corporate authorization documents before opening an account for a foreign branch or representative office. Credit facilities may also call for additional guarantees from the Korean parent.

Korean companies should register trademarks separately in the United States, since Korean trademark registration does not extend protection to New York operations. Attorneys handling trademark registration can align a US filing strategy with existing Korean marks.

Employees hired in New York are generally subject to state wage, hour, and anti-discrimination laws regardless of the employer's foreign origin. A branch or representative office should adopt New York-compliant employment policies before onboarding local staff.

A branch is not a separate legal entity, so the Korean parent is directly liable for everything the branch does in New York. A separately incorporated subsidiary can limit this exposure, but only if the parent respects its separateness. New York courts may still pierce that veil when the parent dominates the subsidiary completely enough to commit a wrong or injustice.

A representative office that starts negotiating contracts, processing payments, or providing after-sales service risks losing its preparatory or auxiliary status under the tax treaty. Once that happens, the office can trigger permanent establishment status and the federal tax exposure a true branch would carry.

Mixing the Korean parent's records with the New York branch's records weakens the separateness that limits liability exposure. Separate bank accounts, ledgers, and corporate minutes support both tax compliance and any future liability defense.
