Consistency Checks

Before finalizing, verify:

• Line 1 legal name matches formation documents character-for-character
• Entity type (Line 8a) aligns with formation structure
• Corporation → Line 8b addresses S corp election status
• "Hired employees" (Line 9b) → Line 10 has specific date (not N/A)
• Nonprofit → Line 8c addresses exempt status filing
• Responsible party title matches governing document role
• Fiscal year (Line 11) matches governing docs
• NAICS code corresponds to Lines 14–15 activity description
• All addresses verified against source documents
• SSN/ITIN provided for responsible party

Deliverables

1. Completed Form SS-4 — All lines filled or marked N/A, matching official IRS layout
2. Transmittal memo — Entity name, responsible party, submission method, special circumstances
3. Preparation notes — Sources per section, assumptions, discrepancies resolved, recommended follow-up

Pitfalls

• Never fabricate or assume entity details — extract only from verified source documents
• Flag conflicts between formation documents (e.g., differing entity names) and resolve before completing
• If S corp election status is unclear, flag for client confirmation
• NAICS codes change periodically — verify against current classification manual
• Form revision date and OMB number must reflect the most recent official IRS version
• The completed form is a certification under penalties of perjury — all information must be verifiable
