Reference Sheet: US Tax Brackets 2025 Explained in Simple Terms. US Federal Income Tax Brackets 2025: A Complete Guide.
The United States uses a progressive federal income tax system, which means your income is taxed in segments, or “brackets.” You don’t pay the same rate on all your income. Instead, each portion of your earnings falls into a specific bracket and is taxed accordingly. Understanding this system can help you plan your finances and estimate your tax liability accurately.
How the Tax System Works
Marginal Tax Rate
The marginal tax rate is the rate you pay on your last dollar earned. For example, if you’re a single filer earning $60,000, your income stretches across multiple brackets, and only the portion that falls into each bracket is taxed at that rate.
Effective Tax Rate
Your effective tax rate is the average tax rate on your entire taxable income. It’s always lower than your marginal tax rate because the lower portions of your income are taxed at lower rates.
Deductions and Credits
- Deductions (standard or itemized) reduce the amount of income that is taxable.
- Tax credits reduce your actual tax bill dollar-for-dollar and can significantly lower what you owe.

Example Calculation
Let’s break down how taxes work for a single filer earning $60,000:
- First $12,950 → 10% → $1,295
- Next $39,900 ($52,850 − $12,950) → 12% → $4,788
- Remaining $7,150 ($60,000 − $52,850) → 22% → $1,573
Total Tax = $1,295 + $4,788 + $1,573 = $7,656
Effective Tax Rate ≈ 12.8%
Notice how even though $60,000 falls into the 22% bracket, the average tax rate is only about 12.8%, thanks to the progressive system.
