Going to the US —
what comes first?
Answer three questions and we will show which services to look at first and what to confirm in your consultation.
For general guidance only. Your final entity type and steps are decided with professionals during the consultation.
Start with your ITIN and personal filings
If you have US income, the first step is sorting out your ITIN and which returns you need.
- Why you need an ITIN and whether it has expired
- Type of US income (rental, investment, refund)
- What to align with your Korean filings
Review your banking and annual filings
With a company in place, start by checking your bank account and the filings that come around every year.
- Bank account and platform payout account
- Annual returns (Forms 1120, 1065, 5472)
- State annual reports and registered agent renewal
Consider a Delaware C-Corp first
If you plan to raise investment, a Delaware C-Corp is the structure investors know best.
- Ownership structure and future funding plans
- Where you actually operate (extra registration if California)
- EIN and bank account timeline
Design your ownership structure first
Buying personally or through an LLC changes the tax on holding, selling and transferring the property.
- Personal vs. entity ownership
- Forming the entity in the property’s state
- Rental income filing and withholding on sale
Choose your entity with California in mind
If you operate in California, compare an LLC and a C-Corp based on California registration and tax rules.
- Tax treatment of an LLC vs. a C-Corp
- California annual minimum franchise tax
- Order of EIN application and bank account opening
Many start with an LLC
Small sellers and local businesses often start with a simple LLC. Foreign-owned LLCs still have annual filing duties.
- Single- vs. multi-member structure and taxes
- Annual filings such as Form 5472
- Order of EIN application and bank account opening
careful with every document and number.

Completion
We deliver the results and walk you through ongoing deadlines.
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.
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.
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.
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.
