Luckily, Visual Capitalist has compiled a study of just how much state income taxes have changed state by state since the year 2000, based upon their income levels. The study found that, among a number of changes, 23 states had decreased marginal income tax rates in the last 25 years. Elsewhere, two states removed income taxes entirely, while two others made no changes whatsoever.

Also of note is the fact that there is no 2000-25 change comparison for four states, as their tax rates were instead charged as a percentage of federal liabilities. Overall, as stressful as taxes can be, the study found that state income tax burdens have mostly decreased since 2000.
