✅ TL;DR (Too Long; Didn’t Read)
Yes, you can legally add a foreign partner (non-U.S. resident or citizen) to an LLC in NYC.
The process is straightforward, but it involves legal filings, tax consequences, and often extra documentation for banking and compliance.
Here’s what you’ll need to do:
1.Amend the LLC Operating Agreement
2.File an Amended Member list with New York State (if required)
3.Issue a new IRS Form W-8BEN (or W-8BEN-E) for tax compliance
Apply for an ITIN (if the foreign partner will file U.S. taxes)
Plan for withholding tax and reporting (Form 1042-S, etc.)

🧠 Full Answer
Adding a foreign partner to a U.S. LLC (especially in NYC) is common, but you need to get it right legally and structurally.

🔄 1. Amend Your Operating Agreement
The first step is to:
Officially add the foreign partner's name and ownership %
Outline capital contributions, profit-sharing, voting rights, etc.
Specify how distributions will be handled (very important for foreign taxation)
Have a lawyer draft or review this — it becomes the internal “constitution” of your LLC.

📝 2. File Updates with New York State
In New York, you don’t file ownership info publicly when forming an LLC — but you may need to:
Update the Biennial Statement
Notify your registered agent or publication agent, if one is used
This ensures your internal docs and state filings stay aligned.

💵 3. IRS Compliance: Tax Forms
Foreign members don’t get a W-9. They must submit:
Form W-8BEN (for individuals)
Form W-8BEN-E (for entities)
This tells the IRS that the partner is not a U.S. taxpayer and ensures the LLC applies proper withholding tax on their share of income.

🧾 4. Apply for an ITIN (Optional but Often Needed)
If the foreign partner needs to file a U.S. return (to claim a refund or file U.S. taxes), they’ll need an ITIN (Individual Taxpayer Identification Number) using Form W-7.

This is usually handled during the first tax year.

💡 5. Understand Withholding Obligations
Foreign partners may trigger U.S. tax withholding:

Typically 30% on effectively connected income (ECI) or FDAP income
You’ll file Form 1042 and 1042-S annually
If the partner is from a country with a tax treaty, that rate may be reduced — but you must apply it properly.

🔍 What Was Wrong or Missing in the Existing Answer:
❌ The existing answer doesn’t address U.S. law at all
→ It’s vague, generalized, and full of off-topic advice like researching a company’s background — not helpful for legal LLC ownership in New York
❌ No mention of:
Operating agreement updates
IRS non-resident tax compliance
ITIN/W-8BEN filings
Withholding rules

❌ Mixes partnership and LLC concepts improperly
→ A foreign “partner” in an LLC is called a member — this distinction matters

🧭 Final Word
You can absolutely add a foreign member to your NYC-based LLC — but treat it like a legal and tax-sensitive process:

✅ Update your operating agreement
✅ Get the right IRS forms (W-8BEN)
✅ Work with a CPA to handle withholding and ITINs
✅ Consult an attorney for compliance with both state and federal laws
Good luck and I hope this helps.
