So a single filer, making 30k with no children the Tax Foundation says that they would have a $253.75 increase to their tax burden. But doing a “custom” tax situation with their calculator and putting in the same details (single 30k no kids standard deduction) I get an increase in taxes by $332.75. Doing the math myself I get a tax burden increase of $114.00.
So their bracket goes from 12% to 15% but none of these numbers line up. The Tax Foundation clearly is manipulating something.
