There is a catastrophic misunderstanding of mathematics that plagues the American workforce. Millions of people have actively refused raises or denied promotions because they were terrified that the raise would "bump them into a higher tax bracket," resulting in them taking home less money than before.
This is mathematically impossible. Because the United States uses a "Marginal" tax system, getting bumped into a higher bracket will never, ever result in you having less total money. The misunderstanding stems from a failure to realize that tax brackets act like a staircase, not a flat tax.
Imagine a simplified tax system with two brackets: 10% on your first $50,000, and 20% on anything over $50,000.
If you make $49,000, you pay 10% on all of it. If you get a raise to $51,000, the great myth says that your entire salary is now taxed at 20%. This is entirely false. Your first $50,000 is still safely taxed at 10%. ONLY the new $1,000 that spilled over into the second bracket is taxed at 20%. You still take home more money overall. You never lose money by getting a raise.
This is the terrifyingly high percentage of the absolute highest tax bracket you landed in. If you are in the "24% Tax Bracket," it only means that the very last few dollars you earned were taxed at 24%. It does not apply to your whole salary.
This is the true, honest mathematical average of what you actually paid. Even if you are in the "24% Marginal Bracket," because your lower income was taxed at 10% and 12%, your true Effective Rate might only be 14%. This is the only number that matters.
