The US system is pay as you go, so it is just paying taxes on time, not ahead of time. Tax day is just the date when all your accounts are supposed to be settled up for the year.
Ahead of time in this context is before filing your taxes. Certainly waiting until the EOY isn't allowed but since estimated taxes are due quarterly for individuals who don't get a W2 it isn't that different.
My point wasn't "you paid early" but "by the time you fill out you already paid"
