Box 12a, Withholding Agent's Employer Identification Number (EIN)(p26)

rule
You are required to enter your EIN. However, if you are filing Form 1042-S as a QI, WP, or WT, enter your QI-EIN, WP-EIN, or WT-EIN. The Withholding Agent's EIN cannot be truncated.
If you do not have an EIN, you can apply for one online at
www.irs.gov/businesses/small or by telephone at 1-800-829-4933. Also, you can apply for an EIN by filing Form SS-4, Application for Employer Identification Number. File amended Forms 1042-S when you receive your EIN.
To get a QI-EIN, WP-EIN, or WT-EIN, submit Form SS-4 with your application for that status. (See the definitions for Qualified intermediary (QI), and Withholding foreign partnership (WP) or withholding foreign trust (WT) in Definitions, earlier, for more information.)
