Previously Announced:

In early September 2016, New Jersey Governor Chris Christie announced that he would be ending a nearly four-decade old tax agreement with Pennsylvania. Under this agreement, New Jerseyans and Pennsylvanians working across state lines were allowed to pay taxes where they live, rather than where they work. The change is anticipated to go into effect January 1, 2017 and will affect income earned beginning that tax year. Ending the deal will create a higher tax burden for residents of Pennsylvania and New Jersey alike.

Let’s briefly compare the tax rate structure between Pennsylvania and New Jersey. Pennsylvania taxes income at a flat rate of 3.07%, regardless of filing status. New Jersey, however, has a graduated tax rate system, where residents pay as low as 1.4% and as high as 8.97% based on income amounts. The lower a taxpayer’s income, the lower the tax rate will be, and vice versa. With that said, there are two primary groups who will pay more in taxes in the upcoming years.

Impact on NJ Residents

Any New Jersey residents who commute to Pennsylvania for work and earn low amounts of income will pay more in tax. This is due to the fact that, depending on your filing status, you could earn up to $70,000 before New Jersey taxes income at a rate greater than the Pennsylvania rate. Let’s walk through a brief example and assume a married couple lives in New Jersey, works in Pennsylvania, earns a total of $50,000, and files a joint income tax return. A quick run through the calculations show that the total New Jersey tax would come to $770. The tax that would be paid in Pennsylvania, however, would come to $1,535. The difference between the two states is $765, pretty close to double the tax the New Jersey residents should be paying. Clearly this is not a good deal for New Jersey residents earning low levels of income and commuting into Pennsylvania for work.

Impact on PA Residents

The same can be said for any Pennsylvania residents commuting to New Jersey for work and earning high amounts of income. This is due to New Jersey’s graduated income tax system. As another example, let’s assume that a married couple lives in Pennsylvania, works in New Jersey, earns $1 million, and files a joint income tax return. Running through the calculations show that the Pennsylvania tax due on this income would be $30,700 based on the flat tax rate of 3.07%. The New Jersey income tax would total to $72,478, however, because of the state’s graduated tax rates. The difference between the two states is $41,778, which is more than double the amount the Pennsylvania residents should be paying. Clearly high income earners living in Pennsylvania and working in New Jersey will also be hurt by the decision to end the tax agreement between the two neighboring states.

Next Steps

Unfortunately, many taxpayers in both New Jersey and Pennsylvania will see their income taxes rise in the coming years as a result of this action.
