You'll use the information from your Forms W-2 to complete your tax return. After filing, retain a copy of the forms for your records. When filing electronically:

• You must provide a copy of your Forms W-2 to the authorized IRS e-file provider before the provider sends the electronic return to the IRS.
• You don't need to send your Forms W-2 to the IRS. Keep them in a safe place with a copy of your tax return.

For general information about e-file, refer to IRS Free File: Do your taxes for free.
