I would like to file jointly with my spouse. I am self employed and my husband is employed - what version would we get for a MAC Download?

To complete a coupled return (where both returns are prepared simultaneously) with self-employment income, the best choice is TurboTax Self-Employed Online. Your spouse isn't self-employed but that's quite alright! Just indicate in the Profile section that your husband has a T4. You will be charged the TTSE price for your return and your spouse's return will be discounted.

Here's a link for more information on TurboTax Self-Employed:
