I've given examples that are TRUE:
A couple makes $100k, no kids, no mortgage, currently make too much money to get much of a student loan deduction (based on income).
Today they would pay:
$100,000 AGI
-$12,700 Stnd Deduction
-$8,100 Pers Exemption
= $79,200 TAXABLE INCOME
First $18,650 is taxed at 10%
Next $57,250 is taxed at 15%
Next $3,300 is taxed at 25%
Total Taxes are $11,277.50 for this couple.
Under Trump it's more simple and saves them more money:
$100,000 AGI
-$24,000 SD
=$76,000 TAXABLE INCOME
All $76,000 is taxed at 12%
Total Taxes are $9,120 for this couple.
In this scenario Trumps plan saves this couple more than $2000 dollars.
