I made about $20k this year with my business before deductions and expenses subtracted ($15k estimated profit) I had to sell my rental property due to divorce in order to pay him his share of the equity in the marital home which my children and I live in currently. The 3.3% was already taken for capital gains for the state of CA out of the proceeds by escrow/title. What if any liability do I have for Federal capitol gains taxes and how and where do I report it exactly on my return.
