I'm not doing any of this. It's HR 25 that will do such.
Compliance to tax laws cost money. You can find out yourself how much compliance to the income and payroll tax adds to prices, reduces wages, and decreases ROI....you don't need or want information from me. There are dozens of experts out there who have published research on the topic.
And yes they say 90% of compliance costs will be eliminated. I won't bother you with a link, again, as you've asked not to be "spammed" with links (even thou you ask for them first!).
By "scrapping the code", as you put it, the cost of complying with tax laws is reduced by 90%.
Of course under the NRST it is the business, not the consumer, who is responsible for keeping receipts, so they will still have that expense. Under the income tax, business AND consumers must provide receipts on demand by IRS.
It would be nice to be able to eliminate 100% of compliance costs, but I'm still waiting for that bill to be introduced.
