The payroll office seems to insist that the reciprocity rule between Maryland and Pennsylvania applies only to state taxes, and that it does not apply to PA local taxes or PA SUI/SDI taxes. They say PA local tax and PA SUI/SDI taxes are required in PA for MD resident (domicile) working in PA. So, I am trying to find some written reference about the reciprocity rule for my own records. Do you happen to have a reference to share? thanks for the follow up
