For those who are independent contractors, as well as for those who work for themselves, a W9 Form is needed to report their Social Security Number or business Tax Identification Number to their clients. This is a pretty cut and dry piece of paper when it comes to government forms. You will simply need to provide your name, your address, as well as your Social Security Number (or your Employer Identification Number, for those who are contractors and are thus considered a separate business entity all their own).
Besides the above information, a W9 will also ask whether you are subject to backup withholding. What is "backup withholding," you might ask. Well, that is withholding at a flat rate of 28 percent on payments made to you or your business under certain circumstances. There are a couple of common reasons for using backup withholding. One reason is if your name and Social Security Number does not match the name and Social Security Number that the IRS has on file for you. Another reason would be if you have outstanding tax debt. In this case the IRS would have notified you that you are subject to mandatory backup withholding until the outstanding tax debt is completely paid for.
During the tax season of the year, contractors will be getting W9 forms to complete. Since during that time of the year, clients are getting ready to send out their 1099 forms. The 1099 Form is used to report self-employment income.

This is utilized to ask, officially, from a person or business their name, address, and taxpayer identification number in order for the requesting party to properly issue tax documents to the IRS.
