you will collect the sales tax from the buyer - so your prices remain constant to the buyer

+30% tax.

Presently, a $100.00 gross sale would be minus any income taxes due, the balance is mine.

After a sales tax, the same $100.00 gross sale would be minus 23% with only $77.00 left to spend...

$77.00 minus 23% taxes yet to pay when I want to, or have to spend it.

My $100.00 gross sale after the sales tax would be taxed at 41%...The remaining $59.00 would have to include the cost of the goods sold, profit, wages etc.

you have omitted other areas of savings in your operations - all of the stuff you buy in production will be cheaper.

So whatever profit margin you require (hence the $100 price) can still be obtained with a lower price.
