As a business owner, I would hate to deal with a VAT. The less paperwork I have to do, the more productive I can be. The mechanism of collection for a NRST seems to be cleaner than a VAT. It won't take hordes of 'agents' peeking into every companies processes to make sure of compliance. And I also saw somewhere back in the thread that the VAT cost can be shown to the end user. How would that be? Would there be some kind of statement on each purchase as to the amount of VAT is in the price?
Yep. A percentage of the purchase price, just like the sales tax.
You have to calculate your income and apply a percentage to figure your social security. Use the same number you calculated for your social security and multiply by the tax rate. You're done.
Actually, while we're on social security, I think social security privatization will kill the NRST. The NRST delinks income from SS tax payments. High earners will not accept that their SS accounts should be lower than low earners.
