Trump’s “genius tax move” was actually something is routine. I’ve done it myself, though it was for 7k not 956M.
For business returns, you add up income and subtract expenses. If you’re negative, you handle it accordingly, depending on the corporate structure.
You can roll losses into your personal return as long as the business activity is not a passive activity on your part.
To me, the real issue with the tax release is “Who released these?”
I suspect it was a state employee. There should be computer access records showing when returns are accessed and by whom. This is how the authorities need to address privacy suits.
All of us with half a brain, take advantage of every legal tax deduction that is available to us.
There is nothing that is criminal, when we obey the tax laws and get a legal deduction.
