If you are selling it for more than you purchased it then you will have to pay taxes on the gains.
The only other tax is the transfer fee tax which is less than 1% of the selling price and is paid at the closing table.
There is the realty transfer tax that you will have to pay, as does every other seller in NJ. I am wondering if you bought your house with a USDA mortgage, which does have some penalties for not carrying the loan long enough. I would like to help, but need a little more information. Please contact me and I will include a mortgage rep and an accountant to help advise you on your situation.
