I have a day job (W2 - $80k) and run a sole proprietorship. My wife also runs a sole proprietorship. We fill out two separate schedule Cs, one for each dba, and my business has been accumulating a carryforward loss for the past few years (now approximately a total of $20k), while hers has shown net profits for the past few years (approximately $13k per year). The TT software combines our businesses when calculating any QBI deduction, which causes my carryforward losses to eliminate the QBI deduction from her pass through business gains, but does not apply the losses against her profits. It seems strange that the combination of the two businesses only work against us. Why do my losses only count against the QBI deduction for her business, but not when it comes to offsetting the profit? I cannot find anything on this subject after many hours of research from numerous sources.
