Is a W-9 Form needed for Corp to Corp?

What makes you think a corporation does not have to provide a W-9 when requested. People often request a W-9 from our company for service work, and we provide it. It includes your verification of tax name, ID, and address, other names you do business as, whether you are an individual or corporation, and whether you are exempt from withholding. If you do not provide the W-9 when requested, they would be required to withhold 28% federal tax from payment for your services.
