In the software I have indicated that I am a part-year resident. It asks for what allocation of dividend and interest income were earned in Maryland (and number so small that it can't make a real difference (approximately $16). The software then asks me what portion of my wages were earned in MD and I input all of my wages that were earned in MD (approximately $31,000). It then goes though MD additions, subtractions, and adjustments. The only adjustment we have is our moving expenses. There are no additions. The only subtraction I have is the Maryland Two-Income Subtraction, which we (my wife and I) get the standard subtraction. The software then gives us the standard deduction of $3,908. After all of this it lists our Federal AGI, our MD additions ($0), our MD subtractions ($1,200), and our Maryland income, which it now lists as around $41,000. It makes absolutely no sense to me.
