Have you been audited every year since then? I was audited about 20 years ago. Every crevice, and they found that they owed me money and wrote me a small check. (I had made an error that hurt me) I've never been audited since then.
I would imagine the same applies to trump, and his team of accountants.
.The man probably has a couple hundred pages to my 30 or so, so, no I do not think there will be any there, there.
If you were an accountant for trump, for any one of his business ventures, or perhaps a business consultant lawyer, would you allow your client to file a sloppy tax return?
