Fuzzy math there, dude.
You forgot to factor in the drop in the federal tax rate from 15% to 12%.
Your example family, under the existing plan would pay $4,665.
Under the GOP plan, they will pay $4,320.
That's a savings of $345.
Not a huge savings, grant you, but still a savings.
60,000 minus the old standard deduction plus exemptions equals $28,900, and when taxed at 15% that is a payment due of $4,665.
60,000 minus the new standard of $24,000 (and no exemptions) leaves us with $36,000, and when taxed at the new rate of only 12%, the payment due is $4,320.
And, that's just for a family of four with two kids over 17. If the two kids were younger, the parents would get an additional $4,000 child care credit.
At any rate -- don't quit your day job and become either a mathematician or a paid tax preparer.
Well that's not how taxes are computed. I grant you that the GOP plan is at 12% a fact I didn't know when I did the computation. But here is how it is done.
2018 tax year
$60,000 minus standard deduction of #13,000.00 for 2018 equals $47,000.00
$47,000 minus Personal exemption of $4150 times four dependents , equals $47000 minus $16,600.00 equals $30400 AGI
$30,400.00 AGI put one in the 15% tax bracket for 2018
Thus the first zero to $19050 is subject to 10% which equals $1905
Then you subtract $19050.00 from $30,400.00 which equals $11,350.00 which is the amount that is subject to 15%
so .15 times $11,350.00 equals $1702.50
Finally you add the ten percent rate to the fifteen percent rate as follows $1905.00 plus $1702.50 which equals a total tax of $3607.50
That's how you compute taxes
Now the GOP plan
$60,000.00 minus standard deduction of $24,000.00 equals $36,000.00
There are no other credits to take now so this puts us in the 12% tax bracket in the GOP plan.
from Zero to $9525 tax is computed at 10% which equals $952,50
Then from $9525 to $36000 is a difference of $26,475.00 that get taxed at the 12% rate which equals $3177.00
Add the two results for a final tax ,thus $3177.00 plus $952.50 equals $4129.50
So the 2018 tax was $3607.50 and the GOP tax was $4129.50 a difference of $522.00
Not what I previously reported and I should have corrected my error. But it's not me who should not quit his day job.
