I need to correct the wrong employer id number on our tax forms

To correct: Please open your return in TurboTax.

• In the search box type: W-2 
• click on Jump to W-2 
• On the W-2 summary screen, click Edit next to each W-2 on the return and make sure the EIN in Box b exactly matches what's on your W-2 form. If not, make the correction.
• Next, make sure the info in the Employer's Name and Address fields match your paper W-2.  If not, make the correction.

If you were able to correct the return with the information above, you can now re-transmit the return.

If you were unable to resolve your issue with the solution provided above, here are your options:

• Contact your employer to make sure their EIN and name on the W-2 they sent you match.
• If your W-2 is incorrect, correct the information in TurboTax and re-transmit your return.
• Ask your employer to send you a corrected W-2 for your records.

If neither of the options above work, you can mail in your tax return.  The IRS won't let you e-file a return if the EIN doesn't match what's in their database.
