Forming an LLC or corporation: what to expect

You form an LLC or corporation by filing a short formation document with your state's business filing office and paying the state fee. Most states let you do it online.

What you usually need

A business name that's available in your state (most offices have a free name search).
A registered agent with a physical address in the state, to receive legal papers.
The formation document: often called Articles of Organization (LLC) or Articles of Incorporation (corporation). Some states use other names.
The state filing fee, paid to the state.

Things people miss

Forming the entity is a state filing. Tax IDs come separately. An EIN comes free from the IRS at irs.gov, and state tax registration is a different agency.
Many states require a recurring report and fee to stay active. See annual reports.
Private filing services exist and charge their own fees on top of the state fee. You can file directly with the state.
