Income Tax Brackets

How Marginal Tax Rates Work
A common tax misconception is that your entire income is taxed at the rate of the bracket you fall into. This is not true. The U.S. tax system is progressive; it uses marginal tax rates, meaning income is taxed at different rates depending on income levels.

Think of your gross income as filling a series of buckets*.

  • The first $16,100 you make (standard deduction) is tax-free
  • Money in Bucket 1 (fills up to $12,400) taxed at 10%
  • Money in Bucket 2 (fills up to $38,000) taxed at 12%
  • Money in Bucket 3 (fills up to $55,300) taxed at 22%

If you continue earning, this continues until the seventh (highest) tax bracket, which is capped at 37%. You only pay the higher rate on the overflow money that spills into the next bucket.

Imagine you are at the top of the 12% bracket and receive a $1,000 raise that pushes you into the 22% bracket.

Your existing income remains taxed at the lower rates.

Only the extra $1,000 is taxed at 22%.

*These numbers are approximate for a single filer in 2026 to illustrate the math; actual brackets change yearly.

I work in HR. Once a year, someone turns down a promotion because they think moving into a higher tax bracket will mean their entire paycheck gets taxed at the higher rate and they'll take home less money. This is mathematically impossible. Please stop this. You are playing yourself.
