How US Tax Brackets Actually Work

“I don’t want a raise — it’ll push me into a higher tax bracket.” It’s one of the most common money myths, and it’s wrong. Because the US uses a progressive system, moving into a higher bracket never lowers your take-home pay. Here’s why.

Brackets tax slices, not your whole income

Each tax rate applies only to the income that falls within its band. For a single filer in 2025:

• 10% on the first $11,925
• 12% from $11,925 to $48,475
• 22% from $48,475 to $103,350
• 24% from $103,350 to $197,300
• 32%, 35%, 37% on higher bands

Why a raise always helps

If a raise pushes part of your income into the 24% band, only the dollars above the threshold are taxed at 24% — everything below stays exactly as it was. You always keep the majority of a raise. There’s no cliff where earning more leaves you with less.

Marginal vs effective

Your marginal rate is the tax on your next dollar (useful for deciding on a raise or a 401(k) contribution); your effective rate is your average across all income. We dig into both in effective vs marginal tax rate.
