People keep thinking the NJ exit tax is an additional tax. It is the same tax you would have had to pay anyway on your income tax return for the house profits. Nothing unusual or nefarious about it. Exit tax is a loaded term that makes people think it is some kind of extra tax for leaving when it’s not. When the state tax return is filed if the amount of tax on the home sale was wrong, they give a refund just like with any overpayment of income tax. So what if the seller moves to another state and doesn’t pay the tax due on the sale? They have to track them down in another state. How much is that going to cost?
