I'm self employed, simple consulting work. I've been purchasing the self employed turbo tax for years. my wife has a standard T4 job. can I use 2 different turbo tax?

You can use a different version than your wife if you file separately, but somethings will be different. For example, optimizers won't be available because there is no other spouse to optimize with.

Thank you.  Exactly, one of the pitfalls I imagined.
