I’d need to see what doubling the standard deduction would do to the bottom line but lowering the rate to 25% doesn’t do jack ultimately, especially if the state and local deduction goes away for the full-year (personal) filing. Not sure but it’s not the home run plan I was hoping for so far.
The personal exemption would be eliminated, too, so the doubling of standard deduction isn’t all that impressive. This is particularly true for some group of people whose rate will go UP from 10% to 12%. Everything depends where the bracket breakpoints are IMHO.
