taxmap/pubs/p334-001.htm#en_us_publink1000313164

Social security number (SSN).(p5)

For Use in Tax Year 2013
rule
Generally, use your SSN as your taxpayer identification number. You must put this number on each of your individual income tax forms, such as Form 1040 and its schedules.
To apply for an SSN, use Form SS-5, Application for a Social Security Card. This form is available at Social Security Administration (SSA) offices or by calling 1-800-772-1213. It is also available from the SSA website at www.socialsecurity.gov.

Individual taxpayer identification number (ITIN).(p5)

For Use in Tax Year 2013
rule
The IRS will issue an ITIN if you are a nonresident or resident alien and you do not have and are not eligible to get an SSN. In general, if you need to obtain an ITIN, you must attach Form W-7, Application for IRS Individual Taxpayer Identification Number, with your signed, original, completed tax return and any other required documentation and mail them to the following address.


Internal Revenue Service
ITIN Operation
P.O. Box 149342
Austin, TX 78714-9342


The exceptions are covered in detail in the instructions for Form W-7. If you must include another person's SSN on your return and that person does not have and cannot get an SSN, enter that person's ITIN. The application is also available in Spanish. The form is available at IRS.gov or you can call 1-800-829-3676 to order the form.
EIC
An ITIN is for tax use only. It does not entitle the holder to social security benefits or change the holder's employment or immigration status.

Employer identification number (EIN).(p5)

For Use in Tax Year 2013
rule
You must also have an EIN to use as a taxpayer identification number if you do either of the following.
If you must have an EIN, include it along with your SSN on your Schedule C or C-EZ.
You can apply for an EIN:
taxmap/pubs/p334-001.htm#en_us_publink1000313168

You may need to get a new EIN if either the form or the ownership of your business changes. For more information, see Publication 1635, Understanding Your EIN.

When you need identification numbers of other persons.(p6)

For Use in Tax Year 2013
rule
In operating your business, you will probably make certain payments you must report on information returns. These payments are discussed under Information Returns, later in this chapter. You must give the recipient of these payments (the payee) a statement showing the total amount paid during the year. You must include the payee's identification number and your identification number on the returns and statements.
taxmap/pubs/p334-001.htm#en_us_publink1000313170
Employee.(p6)
If you have employees, you must get an SSN from each of them. Record the name and SSN of each employee exactly as they are shown on the employee's social security card. If the employee's name is not correct as shown on the card, the employee should request a new card from the SSA. This may occur if the employee's name was changed due to marriage or divorce.
Form W-4, Employee's Withholding Allowance Certificate, is completed by each employee so the correct federal income tax can be withheld from their pay.
If your employee does not have an SSN, he or she should file Form SS-5 with the SSA.
taxmap/pubs/p334-001.htm#en_us_publink1000313171
Other payee.(p6)
If you make payments to someone who is not your employee and you must report the payments on an information return, get that person's SSN. If you must report payments to an organization, such as a corporation or partnership, you must get its EIN.
To get the payee's SSN or EIN, use Form W-9, Request for Taxpayer Identification Number and Certification.
A payee who does not provide you with an identification number may be subject to backup withholding. For information on backup withholding, see the Form W-9 instructions and the General Instructions for Certain Information Returns.
