Bottom line: If a company makes $1MM in revenue and pays $1MM in salary, they owe taxes on $800k profit. Yes, this is actually the law now.
I guess the one area this tax law particularly affects are bootstrapped revenue-generating (non-VC funded) startups with high dev costs? i.e., actual running businesses not playing with monopoly money.... which maybe Elon doesn't care about....
"Note: these changes were signed into law in 2017 but came into effect in 2022"
Like I thought, changes were meant to be a time bomb if the GOP wasn't in control.
