I'm still pretty ambivalent about it. I'm cautiously optimistic I would say.

One common thing that I see, a lot, is dropped T4 data between your employer and the government. Especially box 40 for some damn reason. You should always double check your T4 with what the government has, and I think this will get lost here. There's going to need to be significant data validation improvements for this to work, and the minute I hear the words AI (which we haven't thus far), I'm out.

Also banks are notoriously slow with filing T4RSPs and T5's, they are required by law to have it done by the deadline, but more times than I can count I've seen discrepancies, and that usually ends in you not getting the amount of deduction that you should be (and it could get lost in translation between year's).

Again, cautiously optimistic, but what about these scenarios? For you and me, it's probably minor differences in the rare circumstances something pops up, but you start multiplying that by a bunch of people, and that means an adjustment needs to be found and corrected. All by the agency that's currently mind boggled and doom spiraling over figuring out how to get enough people to pick up the phone.

I mean I hate doing taxes, I want everything to be automatic, and yes it's a pain in the ass to have to pay someone, but sometimes all that effort might save you some cash in the end, right? Sometimes automatic could maybe cost you. Maybe you don't care (and if you were to be someone who would otherwise be a tardy filer, then you shouldn't care).
