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?"
