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.).

Where to Submit Your Completed Form

After you download the filled PDF, send it directly to the requesting party (usually a client or employer). The IRS does not collect W‑9 forms; they are used for information reporting.
