There is no standard or itemized deduction for the New Jersey tax return.
"In filing your New Jersey state income tax return, you are required to use the same filing status used on your federal tax return. There are a few circumstances that allow you to do otherwise, but generally the same filing status must be used on both returns.
Since no standard deduction or itemized deductions are allowed, the deduction method used on your federal return does not effect your state tax return.
Even though the standard or itemized deductions are not allowed, New Jersey offers tax relief in the form of the following tax credits:
• credit for taxes paid to another jurisdiction,
• property tax credit,
• credit from the previous year's return,
• New Jersey earned income credit (17.5% of federal EIC credit)
• credit for excess unemployment/disability contributions."
"Federal deductions, such as mortgage interest, employee business expenses, and IRA and Keogh Plan contributions are not allowed on the New Jersey tax return."
