Frequently asked questions

Yes. Formation documents are filed online with the state, so in most cases the entire process can be done remotely from Korea. We send you a checklist of what is needed.

As a rule of thumb, companies planning to raise investment or issue shares often consider a C-Corp (especially in Delaware), while small businesses, online sellers and property holders often consider an LLC for its simpler structure. Tax treatment and Korean reporting also differ, so we decide together after hearing your plan.

Delaware has well-developed corporate law and courts and is familiar to investors. California is common when your office or staff is actually in California. If you form elsewhere but do business in California, California registration and tax obligations may still apply, so it is best to decide based on where you will actually operate.

An EIN is the business taxpayer number issued by the IRS. It is used to open bank accounts, file taxes and register with sales and payment platforms. Non-residents without an SSN or ITIN generally apply with Form SS-4, and we support that process.

Yes, through banks that accept remote applications. Approval depends on the bank’s review and the applicant’s situation (business type, documents, nationality, etc.), so it cannot be guaranteed.

An ITIN is an individual taxpayer number for people who have a US tax filing requirement but are not eligible for a Social Security Number. It may be needed to report US rental income, file individual returns related to a US entity, or claim a refund.

Yes. An ITIN expires if it is not used on a federal tax return for three consecutive years. Filing with an expired ITIN can delay processing, so check whether you need to renew before you file.

In most cases, yes. In particular, a foreign-owned single-member LLC must file Form 5472 every year even with no revenue, and failure to file can carry a $25,000 penalty per form. State filings and annual reports are separate obligations to check.

For calendar-year filers, C-Corp returns (Form 1120) are generally due April 15 and partnership-type LLC returns (Form 1065) March 15. An extension can push back the filing deadline, but payment is usually still due on the original date.

Korean residents who set up or acquire shares in a foreign company may need to file an overseas direct investment report under the Foreign Exchange Transactions Act and submit foreign subsidiary statements for tax purposes. Korean filings should be confirmed with a Korean tax professional; we point out what to check during your consultation.

Yes. Non-resident aliens must report US rental income in the US. Korean residents must also report it in Korea as foreign income, so both countries’ filings need to be considered together.

It depends on liability protection, estate and gift planning, and the tax on a future sale. We compare personal and entity ownership with our partner professionals.

Fees depend on the service, the state of formation and any add-ons (registered agent, annual reports, etc.). We confirm the scope in your consultation and then send a quote.
