Are you engaged in a trade or business?
If so, do you KNOW what the legal definition of a "trade or business" is in the law?
You can find it in the tax code at 26 USC 7701(a)(26):
The term “trade or business” includes the performance of the functions of a public office.
There is NO OTHER definition of this term anywhere in the tax code.
FYI.
Maybe but that's not what I'm talking about here. When we learn what the code says about rich people it has consequences for "poor" people.
Because we must be careful what we say about this online, what I said was a form of puzzle to tax researchers, which is not hard to solve online. The question is what is $147,000 a cutoff for in this year's law. When they discover that, they can join it with the answers to the other questions to learn how to classify their own earnings. If you want more explanation I can provide it.
