Is there a way to help ensure the IRS takes a whistleblowing claim seriously and acts on it?

It is critical that as much information and detail be provided to the IRS and when it comes to claiming what damages the IRS has suffered to make sure it covers everything For example when Eric Green filed a case against a restaurant owner who was paying undocumented workers off the books he claimed the IRS was out income tax and employment tax for the untaxed payments to the employees but that also there was unreported cash and therefore income tax for the company as well as unreported sales tax impacting the state This way when damages are calculated later the IRS cannot claim that Eric did not bring them up when he filed the claim ie do not trust the IRS to try and be generous at a time like this it has little incentive to pay you more than it has to
