State income taxes can be progressive, meaning higher income earners pay a larger percentage of their income in taxes compared to lower earners. However, the structure varies by state; some states have a flat tax rate for all income levels, while others implement multiple tax brackets with increasing rates. Additionally, certain states do not impose an income tax at all. Thus, the progressivity of state income taxes depends on the specific tax policies of each state.
