You've formed your New York Single-Member LLC. You filed the Articles of Organization, paid the state fees, and completed the publication requirements. On paper, you have a business. But when you walk into the bank to open a business checking account, they'll ask for one more document: your Operating Agreement.
More importantly, without it, your personal assets, like your home, your savings, or your car, remain exposed to your business' liabilities.
Why One Person Needs a "Contract" With Themselves
It sounds counterintuitive. Why do you need a formal agreement when you are the only owner?
The answer lies in the corporate veil. LLCs exist to create a legal barrier between your business liabilities and your personal wealth. If a client slips at your office or a vendor sues for a breach of contract, a solid LLC structure ensures they can only go after business assets, rather than:
•or your retirement fund.
For single-member LLCs, this barrier is thin. If you don't treat your business like a separate legal entity with its own rules and documentation, a New York court can "pierce the veil." They may view your LLC as a "sole proprietorship" in disguise, leaving you personally liable for every business debt.
