What is the difference between Form 211 and Form 3949-A?

Both Forms 211 and 3949-A are used to report tax underpayments to the IRS.  The biggest difference between the forms is that the Form 211 perfects a claim for an award from the IRS for the information provided where the Form 3949-A does not.  Additionally, Form 211 must be completed with the whistleblower’s real name and signed under penalty of perjury where the Form 3949-A may be completed anonymously.  You can read more about the differences between these forms here.
