State tax filing

Thank you ErnieS0!   If I understand you correctly, stock investment losses (both short term and long term losses) incurred while I was a MO resident can be used against capital gain from the sale of my MO rental house when I file MO return, but I cannot use them when I file NJ return. However, if I also have stock investment losses in NJ, I can use these NJ losses against this capital gain in NJ return.
