 Under the False Claims Act, the Department of Justice is authorized to pay rewards to those who report fraud against the federal government and are not convicted of a crime related to the fraud, in an amount of between 15 and 25 (but up to 30 percent in some cases) of what it recovers based upon the whistleblower's report.The relator's share is determined based on the FCA itself, legislative history, Department of Justice guidelines released in 1997, and court decisions.
