Enclosure 5 - W-9 Domestic 2024.pdf

This is Form W-9 (Rev. March 2024), "Request for Taxpayer Identification Number and Certification," which is a standard IRS form used to obtain taxpayer identification information from vendors or contractors doing business with an organization. This version is included as Enclosure 5 in solicitation number 457675 for an X-ray Microscope Instrument (XRM) being procured by Brookhaven Science Associates, LLC for Brookhaven National Laboratory.

The form requires entities to provide their taxpayer identification information, business name, federal tax classification, and exemption codes if applicable. It includes detailed instructions for completing each section, information about backup withholding requirements, and FATCA reporting obligations. The form contains certification requirements regarding the accuracy of the taxpayer identification number provided and the entity's backup withholding status. This is a standard required form for federal contracting, rather than a document containing specific requirements or specifications for the XRM procurement.
