They’ve really screwed this up, politically. In reality, a tax cut for 4/5ths of Americans, but most will perceive it as a tax increase because of a smaller refund (or having to write a check)... not that I’m surprised that Trump & Co bumbled this one, but honestly not sure how they could’ve done it differently (if you overpay less tax, you naturally will get less back).
Seems as though most Trump supporters will stick with him regardless of how his policies affect them (real or perceived).
Clearly, this was the real, material change in the new law: The Tax Cuts and Jobs Act of 2017 changed the top corporate tax rate from 35% to one flat rate of 21%. This rate will be effective for corporations whose tax year begins after January 1, 2018, and it is a permanent change.
