Flat Income Tax vs. Range Income Tax
Nine states — Colorado, Illinois, Indiana, Kentucky,Massachusetts, Michigan, North Carolina, Pennsylvania and Utah — have a flat income tax, while the rest collect according to income ranges. The ranges that apply to 2022 tax rates vary not only by percentage but also by the amount of brackets within the range, with the fewest being one, the flat tax, and the most being 12. Whether you plan to file as a single or married person also affects the tax rate.
For example, New York state has nine income tax rates: 4%, 4.5%, 5.25%, 5.85%, 6.25%, 6.85%, 9.65%, 10.3% and 10.9%. New York state income tax rates depend on your taxable income, adjusted gross income and filing status. Residency status also determines what’s taxable.
California also has nine state tax brackets: 1%, 2%, 4%, 6%, 8%, 9.3%, 10.3%, 11.3% and 12.3%. The California income tax brackets are based on taxable income as well as your filing status. In California, married couples filing jointly simply double the percentage.
