I spent some time looking at this. All without children who take the standard deduction will get a tax cut. I like this, because when I was a childless renter, the tax code felt pretty unfair to me. I don't have kids, so I didn't really look into how they come out, but I think it is generally a little better unless you have a very large family.
Speaking only of California, everyone who itemizes and would still itemize under the new plan will see a tax increase, simply due to the fact that the change in brackets is not enough to offset the loss of the state tax deduction and the personal exemption(s) in itemizations. If you itemized in 2017 and wouldn't under the new plan, it is a mixed bag.
The elimination of the AMT is an interesting trick. A lot fewer people would trigger the AMT with the loss of the SALT (state and local tax) deduction. Speaking of Californians, people (married filing joint) with AGIs between about $245k and $600k are almost sure to run into the AMT under current tax law due only to SALT and personal exemptions. The super wealthy trigger the AMT less frequently since they hit the highest brackets of the regular tax code and the AMT has a top rate of 28%. They need to claim a lot of deductions before they run into it. But, removing it will mostly benefit the really wealthy - they can now claim those significant deductions that would lower their rate. It makes no sense to remove SALT deduction and eliminate the AMT at the same time. It will only help the quite wealthy.
The loss of the estate take again only impacts the very wealthy. They’re not changing the step-up basis (heirs can sell stocks without the earnings ever having been taxed). Probably more things hidden in there.
My taxes would go up, which isn't the worst thing. I believe in a progressive tax structure. I like that many lower/middle income people get a (small) break. But the bulk of the benefits go to extremely rich. It seems to be taking from the top ~5% to give to the top 0.5%. And also increasing the deficit. It all seems really rushed. I am just waiting for DT to say "Nobody knew taxes could be so complicated!" Thumbs down from me.
