As of 2010, only 43 states require residents to file state income tax returns. Each state has similar requirements for taxpayers, such as the minimum income requirements each resident must meet. The seven states where residents do not have to file state returns are Florida, Texas, Nevada, Alaska, South Dakota, Washington and Wyoming. The states that do require state income tax returns have the same guidelines as the Internal Revenue Service. If you are not required to file a federal income tax return each year you are not required to file a state income tax return either.
Determine your filing status for the tax year. Filing status' are single, married filing jointly, married filing separately, head of household and qualifying widower.
Calculate your adjusted gross income for the year. Adjusted gross income is any taxable income paid to you during the tax year, including any salaries, wages and tips.
Determine whether or not your adjusted gross income is more than the amount of the standard deduction of your filing status. Standard deduction amounts change yearly so you will need to check with the Internal Revenue Service to find out the amount of your standard deduction for the current tax year. If your adjusted gross income is less than your standard deduction you are not required to file a state or a federal income tax return.
If you had withholding taxes deducted from your income for the tax year, you may want to file an income tax return with both your state and federal government even if you are not required to do so to receive a refund of your withholding deductions.
