I work and pay taxes in the state of Maryland, but I reside in PA. My employer is the State of Maryland and will not allow me to pay into PA, so I claim 0 and have Maryland taxes taken out to use to pay into PA. It helps with not getting hammered with a large tax bill at the end of the year when I file in PA. When I file Nonresident through TurboTax it has shorted my Maryland return 2 years in a row for about $300 and I cannot figure out why. Example I'm paying in $6000 and when I complete the state portion it says my return is $5800. I'm at a loss trying to figure this out and google isn't helping so any information would be very much appreciated.
