Question 1

What are the 2025 federal tax brackets?

Accepted Answer

For 2025, there are seven federal income tax brackets: 10% (up to $11,925 for single filers), 12% ($11,925–$48,475), 22% ($48,475–$103,350), 24% ($103,350–$197,300), 32% ($197,300–$250,525), 35% ($250,525–$626,350), and 37% (over $626,350). Married filing jointly thresholds are roughly double.

Question 2

How do progressive tax brackets work?

Accepted Answer

The US uses a progressive tax system, meaning only the income within each bracket is taxed at that rate — not your entire income. For example, if you earn $50,000 as a single filer, only the income above $48,475 is taxed at 22%. The first $11,925 is taxed at 10%, and the portion from $11,925–$48,475 is taxed at 12%.

Question 3

What is the difference between marginal and effective tax rate?

Accepted Answer

Your marginal tax rate is the rate applied to your last dollar of taxable income — it is the bracket you "fall into." Your effective tax rate is your total tax divided by your total income, and it is always lower than your marginal rate because of the progressive system. The effective rate better reflects your actual tax burden.

Question 4

Does my state have income tax brackets?

Accepted Answer

It depends on the state. Nine states (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming) have no income tax. Some states use a flat rate (e.g., Illinois at 4.95%), while others like California and New York have progressive brackets similar to the federal system.
