A system and method for error reduction may reduce errors of tax returns filed with a taxing authority. The system and method for error reduction may include an error reduction component that may compare user-supplied tax information to corresponding tax entity information accessed from a taxing authority. The error reduction component may present the corresponding tax information to the user. If a discrepancy is detected by the error reduction component, the error reduction component may notify the user so that the discrepancy may be corrected before a tax return containing the discrepant information is filed with a taxing authority. The error reduction component may enable a user to correct discrepancies in user-supplied tax information and/or corresponding tax entity information possessed by a taxing authority. In various embodiments, the error reduction component may be implemented with a tax preparation application.
