The Social Security Administration’s Business Services Online website has an online tool for correcting errors on Form W-2. With W-2C Online you can complete up to five Forms W-2C on the computer, submit them, and print copies for your employees and for your records at no charge to you. If you have more than five to correct, then start a new set of W-2Cs.

You will find information and tutorials for this online tool, as well as other business tools, on the Social Security’s employer website.
