I don't see how this is much different from the current situation in the United States.
Most people (I bet HN readership included) are paid under a full time employee structure where the employer files a W2 and deducts all (or most) of the federal taxes the employee is liable for from their paychec. Even if you are a contractor, you're supposed to pay all of your own taxes every quarter (or pay penalties + interest), including your employer's half of the Medicare/Social Security taxes.
The big difference in the United States is that you are still required to file your own forms by April for the previous fiscal year for your tax return. You still have to do work to get a nontrivial amount of money back.
