The rich get a much bigger benefit with the pass through rate of 25%.

where we can easily model our 2016 tax return with new formula. I am single parent of two and living in CA, I donot see how this will help me.

Like me and my wife. The loss of the state and local deduction is huge. I can't believe Republicans from Cali, NY, NJ, WA would vote for this.

Depends on situation but overall it is not helping people in CA, NY, NJ, WA etc

And even then, it will take some time for the actual regulations to be promulgated so such a thing can be done.

The most controversial deduction that's gone is for state and local taxes, which would disproportionately affect filers in states with higher taxes like New York, New Jersey and California. The deduction provides the most benefit to upper-middle-class and wealthy income filers, who could see their taxes go up as a result under the Trump/GOP plan.

On paper, the biggest beneficiaries of the individual changes are low- and middle-income single filers and childless couples who would see more earnings covered by the higher standard deduction. But some families might see a tax increase, since the proposal eliminates the personal exemption that filers currently claim for each taxpayer and dependent. Senior citizens and the blind currently also receive an additional deduction that could be affected by the proposal.

"Based on the details of the plan that have been released, a married couple with two kids earning [under] $79,583 a year would pay more under the Trump plan than under existing law," said Daniel Hemel, an assistant professor of law at the University of Chicago.

It ends up being a tiny amount different.
