I just read up on this payroll tax holiday. Seems like an annoyance for most people. I guess if you were really cash strapped right now it would be helpful, but I doubt you will be any less cash strapped come January when your paycheck goes down to repay this.
It's a shame that the federal government has gotten so bad with money that they can't handle taking 4 months off of collecting taxes. Kind of crazy to think that our federal government, which is in debt, is living paycheck (our paychecks) to paycheck essentially.
