I opened a small company LLC last year (2022) with my wife as a partner, and would like to know if I can file the taxes using Turbotax "Married Jointly".

It depends.

If you live in a community property state (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin), your husband-wife LLC is a disregarded entity for tax purposes and you can file a Schedule C for your LLC on your personal joint tax return (MJF).

If you live in another state, then you have to prepare a LLC return (form 1065). You cannot use TurboTax online to prepare form 1065, but have to use TurboTax Business which is only available as a CD/Download on a Windows computer (not compatible with Mac).

You can purchase TurboTax Business from this page.
