I’m the OP–thanks for informative discussion.
My question involves a personal, limited-scope “local” situation that I think is answered by:
CookingWithGas:
“In the simplest sense, if a person earns income, that income will not be subject to income tax for that person more than once (but see estate tax discussion below). So everything in the original post is correct.”
jtgain:
“But generally once the IRS taxes income once, a person doesn’t have to again pay income tax on the same money. Except in corporate taxes.”
But expanding a bit:
jz78817:
“I think the important way to think of it is that people are taxed, not the money.”
TriPolar:
“It’s been pointed out many times in thread already that it isn’t the money that is being taxed.”
grude:
“I was just going to post this, yes the way people talk about money being taxed gives a confusing mental picture. People or entities are taxed for acquiring income, which means whenever money changes hands taxation is happening.”
These comments suggest that my conceptual mental model of this stuff–per grude, my “mental picture”–is flawed or inadequate.
If I earn $20k, and the IRS says give us $4k tax on this, that reduces the amount to $16. But this $20k wasn’t taxed? I don’t get it. The money isn’t taxed, but the action itself of earning the $20k is taxed? I still give the IRS $4k, so what’s the distinction?
Help me with a model that allows me to understand this. I might be, in effect, bringing only arithmetic to an algebra problem, or only algebra to a calculus problem–or more likely, bringing 2-bits of brain power to an 8-bit or 16-bit problem.
PS–I think I get the principle of basis/gain, if not all the specific complexities of calculating the various types [LIFO, FIFO, average-cost, etc] but that’s not what I’m asking about.
