Your marginal tax rate is the rate you pay on your next dollar of income. Your effective tax rate is the average rate you pay across all your income. They're almost always different, and confusing them leads to bad decisions.
How brackets actually work
Common myth: 'If I earn one more dollar I'll move into the next tax bracket and pay more on everything.' False. Tax brackets only apply to dollars within that bracket.
Example (2026 single filer, simplified, ignoring deductions): if you earned $60,000, you'd pay 10% on the first $12,400, 12% on the next $38,000 (up to $50,400), and 22% on the remaining $9,600. Your marginal rate is 22% (the rate on your next dollar), but your effective rate (total tax divided by total income) is roughly 13.2%. Source: IRS Rev. Proc. 2025-32.
Why this matters
- Pre-tax 401(k) deductions save you money at your marginal rate, not your effective rate
- A bonus or raise is always worth taking: you only pay the higher rate on the new dollars
- Roth vs. Traditional analysis depends on comparing today's marginal rate to your future expected rate
What this lesson is NOT
This lesson is about reading your own tax rate correctly. It is not a reason to fear a raise: only the dollars that land in a higher bracket are taxed at that higher rate, and the effective rate stays well below it.
