You havetwo options. You can use your last pay stub, although this is the quickest, it is not the best way to go. There may be information missing and numbers might not correspond to the W-2.
Contact the IRS. After February 14, you may call the IRS at 800-829-1040 if you have not yet received your W-2. Be prepared to provide your name, address, Social Security number and phone number. You should also have the following information when you call:
- Your employer’s name, address and phone number;
- Your employment dates; and
- An estimate of your wages and federal income tax withheld in 2012, based upon your final pay stub or leave-and-earnings statement, if available.
- File your return on time. You should still file your tax return on or before April 15, 2013, even if you have not yet received your W-2. File Form 4852, Substitute for Form W-2, Wage and Tax Statement, in place of the W-2. Use the form to estimate your income and withholding taxes as accurately as possible. The IRS may delay processing your return while it verifies your information.
If you need more time to file you can get a six-month extension of time. File Form 4868, Application for Automatic Extension of Time to File US Individual Income Tax Return. If you are requesting an extension, you must file this form on or before April 15, 2013.
