When filing electronically taxpayers must provide Forms W-2, W-2G, and 1099-R to the Authorized IRS e-file Provider before the Provider sends the electronic return to the IRS. Providers are prohibited from submitting electronic returns to the IRS prior to receipt of all Forms W-2, W-2G, and 1099-R from the taxpayer. Taxpayers filing electronic returns using a personal computer enter the data from the forms into the electronic filing software themselves. This is similar to the attachment of Forms W-2, W-2G, and 1099-R to the face of paper tax returns. Taxpayers who have not received Forms W-2 from their employers and want to know what to do may obtain information here.
