Form Overview

IRS Form W9S - W-9S

Form W‑9S is the IRS Request for Taxpayer Identification Number and Certification for Certain Payments. It is used when a payer must obtain the payee’s TIN for backup‑withholding or reporting purposes.

It captures name, business name (if any), address, taxpayer identification number (SSN or EIN), and a certification of backup‑withholding status.

Plain English

Some think it’s optional
