What salary range is middle class?

Can anyone who knows taxes tell how this would benefit me? I make $105K per year, nearest I can figure middle class is $77K to mid to high $100s.

Does the standard deduction work in conjunction with things like mortgage interest?

Rounding to $100K for simplicity, is this correct?

Paying 25% = $25K.

Reduce salary by the deduction + child credits ($27K), that means I'd pay 25% of $73K, correct?


No way I can get my taxable income down to the 12% bracket; this is totally confusing.

I understand this is just a proposal.

If it's a choice between standard deductions and itemizing, I am confused on how this helps me.

On a very low level, if I currently get back $3K - $5K per year, does it stand to reason that I'd get more back?
