I was going to ask if you're reporting any of these businesses on Schedule C, but I see you mention multiple LLCs, so unless these are single member LLCs you likely file 1065s and then K-1s flow to your 1040.

It does seem strange that they are coming around to you again for an audit of relatively small businesses.

I'm CFO of a multinational financial services organization of roughly 700 employees. Every single year of my companies existence in its present tax incarnation (the result of a merger/acquisition transaction in 2005) has been audited. Some of the constant IRS presence has been partially self inflicted...where we filed an amended return covering a couple years (almost instant audit on those for a company our size). The most recent examiner started asking questions about an issue that was raised a few years ago that we had to go to Appeals level to resolve. When he started poking around there, I had my tax director call a meeting with me and the IRS examiners boss. I gave them the riot act...the issue had been adjudicated previously and I wasn't going to take our time (or hire attorneys and outside tax advisors) to litigate it again. He understood and shortened the leash on his youthfully exuberant examiner.

Probably worth it for you to politely say "WTF" to this examiner when he shows up for the field visit.
