这是我Google的New Jersey 和 New York state 的情况

Will I Pay Taxes in Both NY and NJ? Not really. While you do have to file taxes with New York and New Jersey, you don't have to pay double taxes. New Jersey residents will receive a tax credit on their New Jersey return for any tax paid to New York, or another state, on income earned in and taxed to both states.

我们的情况是，TurboTax算出来的宾州补交税和往年差不多-几百美金，但马里兰要补交的税高得吓人- 几千美金。
