If it's considered community property income, then yes. I had 2 small home businesses. The CPA I used for several years that was experienced with domestic partnership in my state (WA) said it was community income. She did report the business income and expenses on each of our returns, split 50/50. I still get a little residual royalty income from those businesses, I do our own taxes, and that's how I have continued to report it, split 50/50. I don't know if it matters depending on the state, or if that is true for all states. Hope this helps.
