Common W-9 Mistakes That Freeze Payments

A simple typo on Form W-9 can cause your client to hold your payment or deduct 24% in backup withholding. Avoid these common errors:

• Name Mismatch: Using a "DBA" name on Line 1 instead of your legal tax name.
• LLC Confusion: Checking "Limited Liability Company" without entering the correct tax classification code (C, S, or P).
• Wrong TIN: Using an EIN when you are a Single-Member LLC taxed as a Sole Proprietorship (IRS often prefers SSN here).
• Unchecked Exemptions: Failing to claim "Exempt Payee" status if you are a Corporation.
• Signature Date: Submitting an unsigned or undated form.
