Common Mistakes
Here are the most common formation form mistakes:
Business Name Mistakes
Mistake: Using a name that’s already taken.
Example:
- ❌ “Smith Consulting LLC” (already exists)
- ✅ “Smith Consulting Group LLC” (available)
Why it matters: States reject filings with duplicate names.
Mistake: Not including required designator.
Example:
- ❌ “Smith Consulting” (missing LLC)
- ✅ “Smith Consulting LLC” (correct)
Why it matters: Most states require LLC or Corporation in the name.
Entity Type Mistakes
Mistake: Selecting wrong entity type.
Example:
- ❌ Selecting “Corporation” when forming an LLC
- ✅ Selecting “Limited Liability Company” or “LLC”
Why it matters: Wrong entity type causes rejection.
Registered Agent Mistakes
Mistake: Missing registered agent information.
Example:
- ❌ Leaving registered agent field blank
- ✅ Providing complete registered agent name and address
Why it matters: All states require registered agent information.
Mistake: Using invalid registered agent address.
Example:
- ❌ P.O. Box address (not allowed in most states)
- ✅ Physical street address in the state
Why it matters: States require physical addresses for registered agents.
Owner/Member Information Mistakes
Mistake: Incomplete owner information.
Example:
- ❌ Only providing names, missing addresses
- ✅ Providing full names, addresses, and ownership percentages
Why it matters: States require complete owner information.
Mistake: Incorrect ownership percentages.
Example:
- ❌ Percentages don’t add up to 100%
- ✅ Percentages total exactly 100%
Why it matters: Incorrect percentages cause rejection.
Pro tip: Most mistakes come from missing information or incorrect formatting. Double-check every field before submitting.
