"EITC is one"
The big one.
"significant increase in the standard deduction"
Yes, but closer to a wash than you think, since they took away the personal exemptions.
"child tax credit"
Yep. The initial $500/child took A LOT of folks off the tax rolls.
~Doubling Child Tax Credit from $500 to $1000. That took A LOT MORE folks off the tax rolls.
And now, with the larger standard deduction,
~Doubling Child Tax Credit again, from $1000 to $2000
~Reducing 15% bracket to 12%
~Doubling AGI eligibility to claim Child Tax Credits
~Alimony no longer taxable income
45% will be a thing of the past. And Republicans will continue to blame everyone but themselves.
