Let's try it Dick & Jane style, Kas.
I hire Polk for $10/hour on a normal 40 hour week. That is a gross salary of $400. I withhold 20% or $80 of his wages that HE is obligated to pay for state and federal income tax, social security, and medicare. His check is $320 and the amounts I remit to state and federal government is $80.00 PLUS my employers' required FICA contribution for him PLUS SUTA, FUTA, work comp premiums based on his gross salary, general liability premiums based on his salary, and any other required taxes and/or wage-based insurance.
ALL of that comes out of my gross earnings. I can deduct some or all of it as business expense which helps reduce the taxes that I owe from my business, but the taxes I do pay are on top of all those other employee expenses.
And yes, all of that IS baked into the price of my product sold to my customers.
The only employee based expense I would not have under a Fair Tax system is that I wouldn't pay the employers' share of FICA or FUTA. The other expenses stay the same.
And assuming that I would have to pay Fair Tax on anything I buy for the business that is not for resale, I would guess my taxes would go up a bit above and beyond those payroll expenses.
I'm not positive I understand what you are saying, but let me repeat it back, you can let me know if I went wrong. You're saying that Polk makes $400 a week, and he actually saves his portion of the payroll taxes as well as his withholdings, not me.
Well, let's say his take home pay is $350, the other $50 he was paying in various taxes. Here are my observations.
1) I know the guy, and he isn't worth $400 a week, you're overpaying him.
2) He was actually willing to work for $350 a week. Everyone knows when we switch to the fair tax. His employer is probably going to look at all staff and make some sort of announcement. Like putting out a memo saying that they are cutting salaries by 20%, which covers things like payroll taxes they never got anyway. The memo will explain that this amount leaves them take home as well as they were before, but since taxes are now being paid directly by the employer, they can't pay both. It will also mention that payroll taxes are covered by the fair tax.
3) The best employees at Polk's company will probably get a better deal, something closer to the whole thing. Polk won't get that deal. But they are doing it to retain those employees. Those employees have the market power, there's nothing wrong with that.
4) Polk won't quit because he's still making $350 take home, like he did before.
5) Going forward, take home salaries and job changes will just be calculated on the new method, it's a one time decision every company will have to make.
You have to remember that just like employers are looking at every tax as a cost, employees are looking at take home pay. An adjustment will have to be made. Employers will make it, they won't pay Polk his $400 gross and then pay his taxes for him. And since the change is across the economy everyone will be making it.
You're right that employers can't just absorb it. They won't.
