How To File For a Tax ID Number
From the Inkwell of: Bartholomew J. Worthington III
A tax ID number is used by the Internal Revenue Service to administer tax laws. Social Security numbers are TINs issued by the Social Security Administration. Other TINs, such as an employer identification number or an individual tax identification number, are issued by the IRS for business entities. These tax identification numbers are required on tax-related documents.
1. Determine if you need a Social Security Number or another kind of tax ID number. If you, your spouse or your dependent(s) are ineligible for a Social Security number, you will need to get an individual tax identification number. You will need an employer identification number for the purposes of opening a business.
2. To acquire an employer identification number, apply for it online through the IRS website. You also can complete form Form SS-4, Application for an Employer Identification Number, and fax or mail it in. Complete Form W-7, IRS Application for Individual Tax Identification Number if you are an individual who is not eligible for a SSN.
3. Submit the appropriate application with any required documentation. If you are applying for an EIN, which can be done online or on the phone, you are not required to provide documentation. Supply proof of your identity and your residency status when you submit your application for an employer identification number or an individual tax identification number.
