I suggest we stop taking taxes out of paychecks and have people pay their full taxes once a year. It would help them see the total amount of taxes they pay. It would have a positive effect on government policy.
But it doesn't work for low-income people that are already living paycheck-to-paycheck.
In principle I like your suggestion but in actuality I think many Americans will not like their "yearly tax bill." Just think about people who are already living paycheck to paycheck; not saving much, or just overall spending every penny that comes into their bank account. They would be in trouble come April if they had to pay it at that point.
Perhaps they could do a monthly installment payment for last year's taxes... And the taxpayer would auto pay once or twice a month when they get paid... But then, we're back to where we started.
Tldr in an ideal world where every citizen is disciplined about not spending every penny they get, this suggestion would be great.
I know some people _have_ to spend every penny because they need to to survive, but there are also plenty of people who spend every penny because they just have no discipline and buy anything they want without regard to whether or not they could afford it. Ideally the people in the former category would get some sort of welfare. Not sure what, if anything, to do with the people in the latter.
