Before incorporation: match the structure to the business

Start with the people who own the business, the activities it performs and where work actually happens. A sole proprietorship is not a separate legal entity from its individual owner. Partnerships, LLCs and corporations have different ownership, management and liability rules; professional activities can add licensing restrictions.

An LLC's state-law management arrangement is separate from its federal tax classification. A corporation's C or eligible S tax treatment is also a separate review. For nonprofits, incorporation does not by itself establish federal tax exemption.

Choosing a filing state does not remove another state's registration, employment or tax requirements. Consider investor expectations, governance documents, registered-agent arrangements and recurring obligations with licensed advisors before choosing a structure. No form guarantees protection or tax savings.
