All states have a federal tax filing requirement. However, tax filing requirement is also required at the state level. For individuals, 7 states in the United States have no state income tax. These states are:
|State||US state code|
In addition, there are 2 states that tax interest and dividend income but not earned income:
|State||US state code||Marginal Income Tax|
- New Hampshire residents must file an income tax return only if interest and dividend income exceeds $ 2,400 ($ 4,800 for married filing jointly) + additional exemptions due to age and disability.
- Tennessee residents must file an income tax return only if interest and dividend income exceeds $ 1,250 ($ 2,500 for married filing jointly).
If you are a resident of the other U.S. taxable states, and you have earned income in one of the tax-free states, this income must be reported in your state of residence.
For example, if you are a New York resident and have worked in Texas, you still have to report your Texas state income in the New York state tax return, in addition to the federal tax return.
If you are a resident of one of the tax-free states and you have earned income in one of the taxable states, you must file a tax return in the taxable state as Nonresident.
For example, if you are a Nevada resident and you earn money from work in California, you are required to file a tax return as a Nonresident in the state of California, in addition to the federal tax return.
