If you are a US citizen, a US resident alien, or a US-based entity (such as a Corporation, Partnership, or LLC), you are required to submit **Form W-9** (Request for Taxpayer Identification Number and Certification).

**Note:** If you are NOT a US person or entity, do not use this form. You must submit Form W-8BEN (individuals) or W-8BEN-E (entities) instead.

## **Step 1: Download the Form W-9**

You should always use the latest version of the form provided by the IRS.
