Updated on December 20, 2023 - 10:30 AM by Admin, TaxBandits

Tax forms may often feel like a maze, and the W-9 form is one that corporations and independent contractors frequently need clarification on. Though it may seem challenging, this document is a vital conduit between corporations and contractors. In this article, we'll break down Form W-9, explaining what it is, what information it requests, and how corporations manage it.

1. What is Form W9 for Corporations?

A W9 Form, also known as the "Request for Taxpayer Identification Number, is an IRS document that sends a person's Tax Identification Number (TIN) to their payer (or whoever is responsible for submitting a 1099 with the IRS).


2. What is the Purpose of Form W-9 for Corporations?

The W-9 form is more than just a piece of paper; it's an important tool that helps corporations get vital data from people and organizations that offer services. Essentially, the form aims to get the service provider's taxpayer identification Number (TIN) so corporations can appropriately record income payments to the IRS. The corporation may use a Form W-9 for two different reasons:

  • If the corporation has employed independent contractors or freelancers for any contractual work, they will need to collect their tax information through Form W-9 as it is needed to file the 1099 form.
  • On the other hand, when the corporation renders contractual work to a third-party entity or an individual, it will be asked to fill out Form W-9 to provide its required tax information.

C Corporation (C Corp):

The standard corporate structure is a C corporation. It is a distinct legal entity and must pay federal income tax on its earnings. Every dividend a C Corporation's shareholders receive is subject to individual taxation. Since the corporation and the shareholders pay individual and corporate taxes on the same revenue, this is sometimes called "double taxation."

S Corporation (S Corp):

An S Corporation chooses to distribute its corporate income, losses, deductions, and credits to its shareholders for federal tax purposes. This indicates that the corporation typically does not pay federal income tax. Instead, the shareholders report the corporation's revenue on their tax filings.

  • Exemptions (Line 4)

    This line describes if the corporation is exempt from Backup withholding and FATCA reporting.

    • Exemption from Backup withholding reporting.

      If the corporation is exempt from Backup withholding, enter the applicable code(s) in the corresponding field on line 4. The appropriate code for the corporation is 5. Corporations are exempt from backup withholding for certain payments, including interest and dividends.
