Sure, that sounds good on paper. But here's a list of people who would be hurt by this system unless they were sophisticated enough to realize that they should revise their return:
- Most people with a kid
- Most people supporting a relative
- Most people supporting someone who has no income and lives with them
- Most people who made charitable contributions in 2021
- Many people with a home energy deduction
- Most people who participated in post-secondary education
- Anyone in the gig economy
That's a big list, and it's far from complete. So it's not clear that your proposed "do people's taxes, leave it up to them whether to acquiesce or not" plan is good for consumers overall.
