Required Information Checklist
Legal Business Name
The exact legal name as filed with your state (for LLCs, corporations, partnerships)
✅ What to Bring:
- • Certificate of Formation / Articles of Incorporation
- • State registration confirmation
- • Operating Agreement or Bylaws showing exact name
⚠️ Common Mistake: Name must match state records exactly - including LLC, Inc., Corp., etc.
Responsible Party Information
Individual who controls, manages, or directs the entity
✅ What You Need:
- • Full legal name (first, middle, last)
- • Social Security Number (SSN) or Individual Taxpayer ID (ITIN)
- • Must be an individual person (not the business entity)
⚠️ Common Mistake: Cannot list the LLC or Corp as responsible party - must be a person
Business Address
Physical location of your business (PO Boxes not accepted for principal address)
✅ Address Must Include:
- • Street address (physical location)
- • City, State, ZIP code
- • Must match state formation documents
- • Can be home office if legitimate business location
💡 Tip: Mailing address can be different (can use PO Box), but principal address must be physical
Business Structure / Entity Type
Exact classification of your business for IRS purposes
✅ Know Your Type:
Common Types:
- • Sole Proprietor
- • Single-Member LLC
- • Multi-Member LLC
- • C-Corporation
Also Available:
- • S-Corporation
- • Partnership
- • Nonprofit
- • Estate/Trust
⚠️ Critical: Must match your state formation documents exactly
Business Start Date / Formation Date
When your business legally began operating
✅ Use This Date:
- • Date state approved LLC/Corp formation (check certificate)
- • For sole proprietors: date you started business activities
- • For acquisitions: date ownership transferred
- • For estates: date of death
💡 Note: Cannot apply before your LLC/Corp is officially formed with the state
Principal Business Activity
What your business primarily does to generate revenue
✅ Examples:
- • "Consulting services for small businesses"
- • "Online retail sales of clothing"
- • "Real estate investment and property management"
- • "Software development and SaaS"
- • "Restaurant and food service"
💡 Tip: Be specific but concise (10-15 words). Vague descriptions can delay processing.
Employee Information
Current and anticipated employment numbers
✅ Be Ready to Specify:
- • Number of employees expected in next 12 months
- • Whether employees are household or agricultural
- • Expected first wage payment date (if applicable)
✓ If Zero Employees: That's fine! Just indicate "0" - many businesses get EINs without employees.
