How much does the IRS pay Whistleblowers?

How much the IRS can pay a whistleblower depends on how much the IRS collects as a result of the information you provide.  If the amount of tax identified by the whistleblower (including taxes, penalties, and interest) and then collected by the IRS is more than $2 million, then according to section 7623(b), the IRS can pay fifteen to thirty percent of the total proceeds to the whistleblower.   If the amount of tax identified by the whistleblower (including taxes, penalties, and interest) and then collected by the IRS is less than $2 million, then according to section 7623(a), the IRS can only pay up to fifteen percent of the total proceeds to the whistleblower.
