Anybody out there really understand this bill ? Example married filing joint was $12600 standard deduction plus $8000 ($4K each) exemption for a total deduction of $20600. Yesterday's bill I believe ups the standard deduction to $24000 and removes the personal exemptions thus a +$3400 increased net deduction. Also looks like the tax tables will slightly decreases thus looks like a gain for a normal moderate income retiree. However what is the proposal for counting Social Security income. It's a graduated scale today. Low to moderate incomes get only around half of that counted as income (1040 line 20 A). If they are removing that the net will be moderate retirees will be paying more income taxes after this cut. I did a rough calculation on a case around $70K ($35K SS and $35K other income). If the SS deduction is taken away the taxes will increase more than $1000. Where are the facts ?
