Hello. My specialty is focusing on YOUR Financial needs. Financial Planner/Business Owner for 20 years. CPA,PFS,QFP,GMMA.
This is very hard to "prove". I realize that it's frustrating, but things like cash, under the table take many man hours to prove and the RIS knos this goes on but for what they recover it wouldn't be worth the cost for them to get involved.
It seems like you are a great citizen and person trying to do the right thing.
Unfortunately while you can "report" people to the RIS more than likely it will be a waste of time and postage.
I wish there was a better answer. Even the IRS in the US leaves this alone.
