Common Mistakes to Avoid When Completing the W‑9

• Leaving the Taxpayer Identification Number (TIN) blank – the IRS will reject an incomplete form.
• Using the wrong name format – match the name on your Social Security card or business registration.
• Signing the wrong section – only the signature line at the bottom is required.
• Choosing the wrong tax classification – select the box that accurately reflects your status (individual/sole proprietor, C‑corp, etc.).
