Have you ever gone to do your taxes and realized in a panic that you were missing a W-2 or another important tax document? It’s a scary feeling– especially if it’s April 14th. The best advice is to keep good track of your forms from the beginning of the year by setting aside a special folder or file for the forms. But if you do end up losing one, here’s what you need to do.

Contact your company’s HR or payroll office. Request a new W-2. They should be able to provide you with an additional copy with very little hassle.

Contact the IRS. If your company has gone out of business or you are not able to get another copy for some other reason you’ll need to call the IRS at 800-829-1040. Make sure to have all of your information handy including the employer’s contact information.

Recreate the Form. If you are still not able to get another W-2 you can use form 4852 as a substitute for the w-2. Simply gather the information off of your last pay stub to complete the form.

Look for Mistakes. Make sure there are no errors on your form. If you happen to receive the w-2 you were looking for after you file and the information is different, you will need to refile your taxes. You can do this by filling out a 1040x to amend your taxes.
