Thank you. But perhaps there is some confusion. Partnerships are treated completely differently. From everything else I'm reading, you still treat it as a Sole Proprietorship, but allocate all expenses/income 50/50 (except Self-Employment tax which all goes to one).

My only questions are if it's somehow optional and how to treat inventory.
