That is a business grant and as such is taxable on your federal tax return but not on your New Jersey tax return. You would enter it on your business tax return as "Other Income." That would be on line 6 if self-employed and completing a schedule C to report your business income and expenses.
It would go on line 7 on a partnership form 1065, line 10 on an C corporation form 1120, and line 5 on an S corporation form 1120-S.
Thank you for your great answer about how to enter an NJEDA grant on the federal return. (I upvoted it.) As you suggested, I entered the grant on line 6 of Sch. C. However, after completing my Federal 1040, I am working on my NJ State Return. I need to remove the NJEDA grant from income since it is not taxable on the state return. I was not given any opportunity to allocate or adjust the income, TurboTax automatically transferred the full Sch C income. I can not figure out how to make the adjustment in the NJ return. I was not presented with an adjustment or deduction option in Turbotax "step by step," and see no line on the NJ 1040 that would allow me to do so. Can you possibly advise exactly what line on my NJ-1040 (New Jersey Resident Income Tax Return) I can deduct the grant money on? Thank you so much.
As you navigate through your NJ State return, there is a screen that is entitled Other Non-Wage Income. Here under description enter "Federal taxable NJEDA grant -exempt in NJ", then enter the amount as a negative number. This will exclude this income from NJ taxation.
