For crying out loud!
National Retail Sales Tax (NRST) is functionally no different that a state sales tax!
If I buy $100.00 of goods from you, YOU have to COLLECT FROM ME, an additional $6.00 (6% here in Indiana) on that purchase to send to the state at the end of the quarter. How are YOU paying that!?
NRST would be no different, other than the fact that the money you COLLECT FROM ME for the NRST, will be sent to Washington. Your costs and profit margin on said goods will be untouched.
The problem is, whether it is an income tax or whatever, the tax makes it so my service has to be worth $106. It doesn't matter what you call the tax. I have to collect $106 and pay $6. Whether it is a 6% income tax or a 6% sales tax. Now 6% is no big deal to most, but 30% is. Under the NRST, I as a register retailer have become liable to pay the tax. I pay a 23% tax on my gross income.
