I wish to file 3 personal tax returns. Me, my spouse, and my mother-in-law. All of us receive pension and T-5 investment income. How much will it cost to file?

It depends on if you use TurboTax Online or TurboTax Desktop.

If you use TurboTax Online, you'll need to use at least Premier, which is $40 (plus tax) per return until April 16. That is the price if you prepare your returns yourself.
 

If you use TurboTax Desktop, you can use any version, though we would recommend Premier, which is $90 (plus tax) for 12 returns.
