How Graduated Brackets Work

In a graduated tax system, you do not pay your top bracket's rate on all income. You pay each rate only on income within that bracket. For a single filer earning $100,000 in California, the calculation looks like this:

$10,756 x 1.0% = $108

$14,743 x 2.0% = $295

$14,746 x 4.0% = $590

$15,621 x 6.0% = $937

$14,740 x 8.0% = $1,179

$29,394 x 9.3% = $2,734

Total: ~$5,843 on $100,000 income (effective rate: 5.8%)

Frequently Asked Questions

How many states have graduated income tax in 2026?
29 states and Washington DC use graduated (progressive) income tax brackets in 2026. This means different portions of income are taxed at different rates, with higher income taxed at higher rates. The remaining states either have no income tax (9 states) or a flat rate (13 states).
What is a graduated or progressive income tax?
A graduated (also called progressive) income tax applies increasing rates to increasing income levels. For example, in California, the first $10,756 of taxable income is taxed at 1%, the next $14,743 at 2%, and so on up to 13.3% on income above $1,000,000. Only the income within each bracket is taxed at that bracket's rate, not total income.
Why do some states have more brackets than others?
The number of brackets is a policy choice. More brackets allow finer targeting of different income levels; fewer brackets are simpler to administer. Hawaii has 12 brackets because legislators chose to create more granular rate increases. Alabama has 3 brackets because it went with simplicity. There is no inherent advantage to either approach.
Are graduated state income taxes the same as the federal system?
Conceptually yes, but the specifics differ widely. Federal brackets, rates, standard deductions, and exemptions are different from any state's system. Most states start from federal adjusted gross income (AGI) and then apply state-specific modifications, deductions, and rates. You calculate federal and state income taxes separately.
