I think this is mostly a US thing. Why use yearly salary? You’re not paid once a year, are you? Most likely once a month. Referencing monthly salary makes much more sense.
“I’m making 50k”. Great, now I have to guess - dollars? Monthly? Yearly? If yearly then what’s the monthly paycheck? Net? Gross?
The only people I’ve ever heard talking about “their tax bracket” are the types who refuse to take an extra hours at work because “it’ll put me in a higher tax bracket and I’ll actually earn less money than if I hadn’t worked it at all” even though that’s mathematically impossible.
Someone earning $44,726 will put them a whole dollar into the 22% tax bracket meaning they pay $0.22 more in taxes than if they’d stayed within the 12% bracket of $11,001-$44,725. Claiming “I’m in the 22% bracket” is completely meaningless, as evidenced with the above example, and ignores the fact that this person is much more likely to have an effective tax rate of around 12% or less. If you’re only paying 12% of your income in taxes, why in the world would you say you’re “in the 22% bracket?”
