Export W-2 Information Electronically
You can file your taxes online through the Social Security Administration (SSA) website.
You must save your W-2 information in a format that you can send to the SSA electronically. If an organization has 250 or more employees, electronic filing of W-2s is required; otherwise, it's optional. For more information on these forms and how to file, see the SSA Help on Employer W-2 Filing.
Note: The SSA provides free software called AccuWage that you can use to check W-2 reports for correctness before sending them to the SSA.
