Questions people ask
How is state income tax calculated?
Most states start from your federal adjusted gross income, subtract a state standard deduction and personal exemptions, and apply their own brackets or a flat rate. A few, such as Colorado, Idaho and North Dakota, start from federal taxable income instead. The calculator follows each state’s approach in simplified form.
Which states have no income tax?
Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming do not tax wages. Washington does tax large long-term capital gains.
Which state has the highest income tax?
California, with a top rate of 13.3% on income over $1 million (including the mental health surcharge). Hawaii (11%), New York (10.9%), New Jersey and DC (10.75%) follow. At middle incomes, Oregon often takes the largest share because its 8.75% rate starts low.
Does this include local income tax?
No. Cities and counties in about a dozen states, including New York City, Philadelphia, Detroit, most of Ohio and Pennsylvania, every Maryland county and Indiana county, levy their own income tax on top.
What if I live in one state and work in another?
You generally pay tax to the state where you work on that income, and your home state gives a credit for it so you are not taxed twice. Some neighbouring states have reciprocity agreements so you only file in your home state.
