The myth that scares people from raises, as if one dollar can tax your whole income retroactively.

means A tax bracket is one of the income ranges a government taxes at a specific rate, under a marginal system where only the income within that range gets taxed at it — not your entire earnings.

from The word 'bracket' comes from architecture and printing — a supporting fixture, then a printed symbol ( [ ] ) used to group or set off items. By the 1800s, 'bracket' had extended to mean a grouped category or range, like an age bracket or price bracket. 'Tax bracket' followed naturally once modern graduated income taxes arrived in the early 20th century, needing a word for the sliced income ranges that each rate applies to. The confusion about brackets retroactively taxing your whole income isn't etymological — it's just a popular misunderstanding of how marginal rates actually work.
