How to Complete W-9 Form

What is a W-9 form and why is my customer asking for it!

So one of your customers has asked you to complete a W-9 form before they can pay you.  Why do they need this form that asks for your tax classification and tax ID number!  The short answer is – the IRS.  The IRS requires companies to add up all the “reportable” payments made to vendors and independent contractors during the calendar year and report these payments to the IRS.   This requirement is similar to the way that companies have to report all wages paid to employees.

These payments are typically reported to the IRS on Form 1096 and to the vendor or independent contractor on Form 1099.  The combination of your tax classification (for example – individual, corporation or LLC) and the type of payment made (for example – payments for services, attorneys fees or rent)  determines what must be reported to the IRS.  Payments for “services” to “individuals” are reportable.  However, most payments to “corporations” for “services” are not reportable.  Your social security number or employer identification number is needed to specifically identify you to the IRS.

The whole process of this reporting is called “information reporting.”  In essence, the IRS is requiring companies to track and then “report” payment “information” that would typically be considered income on your income tax return.  What does the IRS do with this information?  They compare the income reported on the vendor or independent contractor’s income tax return against all the income reported on the 1099 and W-2 forms.  If the income reported on the tax return is less than the sum of income reported on the 1099 and W-2 forms the tax return could be flagged to review for under-reported income and consequently underpaid taxes.

Stop using your Social Security Number!

If you work as an independent contractor or sole proprietor you can use an Employer Identification Number (EIN) on your W-9 form and avoid using your Social Security number (SSN).  Apply for an instant EIN number for free at  Online hours for the IRS EIN service are Monday – Friday, 7am to 10pm EST.  Note that independent contractors are considered sole proprietors by the IRS and eligible for an EIN number.  It is also not necessary to have employees to obtain an EIN.

U.S. person

The W-9 form should only be completed by what the IRS calls a “U.S. person”.  Some examples of U.S. persons include an individual who is a U.S. citizen or a U.S. resident alien.  Partnerships, corporations, companies, or associations created or organized in the United States or under the laws of the United States are also U.S. persons.

If you are not a U.S. person you should not use this form.    You will likely need to provide Form W-8.

To get started, download the latest W-9 form from the IRS website. Check the date in the top left corner of the form as it is updated occasionally by the IRS.  The current revision should read “Rev. October 2018″.  Click anywhere on the form and a menu appears at the top that will allow you to either print or save the document.  If the browser you are using doesn’t allow you to type directly into the W-9 form then save the form to your desktop and reopen using Adobe Acrobat Reader.
