Need to get a copy of w-2

If your employer hasn’t sent you the form yet, contact them and ask for a copy. Make sure they have your correct address.

 Check Online: many payroll services have online access.

 If you’re unable to get your Form W-2 from your employer, contact the Internal Revenue Service at 800-TAX-1040. 

• The IRS will contact your employer or payer and request the missing form.
• Let them know: •
  •  your name, address, Social Security number and phone number; • 
  • your employer’s name, address and phone number; • 
  • the dates you worked for the employer; and • 
  • an estimate of your wages and federal income tax withheld last year. 
  • You can use your final pay stub to figure these amounts. 
• You can get a free Wage and Income transcript from the IRS - Note: this will not include state information.  https://www.irs.gov/individuals/get-transcript

If, after contacting the IRS, you still do not have your Form W-2, you have two choices: 

1.  File your return by the April due date and use Form 4852, Substitute for Form W-2, Wage and Tax Statement. Try to estimate your wages and withholding as best you can. 
2.  Ask for more time to file by using Form 4868, Application for Automatic Extension of Time to File U.S Individual Income Tax Return. You can even e-file the request.
