I file an MD non-resident 505 return every year for income from a rental.
I had a strange thing this year that doesn't make sense. The MD return works like most (I guess) non resident returns in that you start with your federal 1040 AGI and then add and subtract various things based on MD law. Then you determine your MD source income and use that to determine the fraction of your modified AGI based on MD sources. So far so good.
What happened when figuring in TurboTax, is that I had losses on my Federal return for LTCG (sked D) and business (sked C) which Turbotax was "disallowing" (adding back to my income) to determine my modified AGI (total of $5,000). Don't see why, but I can live with that. What then surprised me, was that the way TTax figured my MD source income, that $5,000 "phantom" income was added to my "real" MD income, almost doubling my tax liability. That seemed crazy, so I then did it manually using the form and instructions and TTax is doing exactly what the instructions seem to require. I went back and looked at the instructions from 2008 and see that they did in fact change for 2009.
This makes no sense to me at all. How can an LTCG loss on investments or a Hawaii (state of residence) business for an MD non-resident become MD income that is taxed?
