State tax filing

However, be aware that there can be NJ tax implications if the stock was acquired via an employee stock incentive program.  In this case if the acquisition of the stock took place in 2019 and created "compensation", (e.g., a NonQualified Stock Option), or if the sale of the stock creates compensation, (e.g., a disqualifying sale of stock acquired via an Incentive Stock Option), then that compensation will be included with your NJ income tax return.
