Built for the owner who signed the lease, hired the staff, and now needs the bank to see what the P&L doesn't fully tell. This guide covers income qualification, documentation strategy, and lender-readiness scoring for sole proprietors, LLC partners, and franchise operators.
ENTITY STRUCTURE × QUALIFYING INCOME
Your business structure determines which tax documents a lender requests, how they calculate your income, and how complex the underwriting file becomes. Find your entity below.
| Entity Type | Tax Documents | Qualifying Income Basis | Complexity |
|---|---|---|---|
| Sole Proprietor | Schedule C (2 yrs) | Net profit after deductions | LOW |
| Single-Member LLC | Schedule C or 1120-S | Net profit or W-2 + distributions | LOW–MED |
| Multi-Member LLC | K-1 (Form 1065) | Ordinary income + guaranteed payments | MEDIUM |
| S-Corporation | 1120-S + W-2 + K-1 | W-2 wages + % of business income | MEDIUM |
| C-Corporation | 1120 + W-2 | W-2 wages only (no pass-through) | HIGH |
| Franchise Operator | Varies by structure | Depends on entity type above | HIGH |
