Does this in any fashion help pave the way to a more modern tax filing system whereby the government tells you what you owe without today's current labyrinthine filing process like other countries have had?
No. Most of the complexities in the tax system are due to tax incentives and exemptions that the tax payer needs to verify.
All I see is a potential "tax bill" system that would simplify the process for the vast majority of Americans, and the percentage of Americans who file non-standard taxes can continue to do so no different than they do already.
