From what I understand, the panel has recommended repealing the Alternative Minimum Tax (AMT), which was intended to tax only the wealthy, but has increasingly been falling on the middle-class (4 million taxpayers last year, and a projected 21 million taxpayers next year are subject to the AMT). The panel also was charged with coming up with recommendations that were revenue-neutral, so by recommending repeal of the AMT, the panel had to recommend other tax law changes to offset the loss of the AMT.
I don’t fully understand the home interest deduction proposal. What I’ve seen has suggested that the current cap on deductible interest ($1 million) will be reduced to the maximum amount that the fed will guarantee in loans, which varies from market to market but caps out in the $300-400, 000 range. I also read somewhere that the deduction will change to a credit, but I don’t know if that’s correct. In addition, the proposal suggests eliminating deductions for state and local income tax (including property tax as well). The additional revenue from the proposed changes supposedly will offset the $1.2 trillion (over ten years) lost in repealing the AMT.
In addition, the marriage penalty has decreased (or the marriage bonus has increased, depending on your perspective).
As one cynic has put it, to determine whether you will be harmed or benefitted by these proposals, pull out the map of the last election. If you live in a red state, you’re likely going to see no change or some benefit (because these areas generally have lower property values and hence lower mortages, as well as lower or no local taxes). If you live in a blue state, however, you’re likely to see higher taxes. This is, of course, an oversimplification, but the numbers that I’ve seen bandied about indicate that under this proposal, an even greater proportion of taxes will be paid by the blue states than by the red states than is currently the case. (This, of course, presupposed the existence of “blue” and “red” states, which is a gross oversimplification of our purple nation’s majesty.)
It will be interesting to see how this plays out in my neck of the woods, if the proposal goes through. Couple a booming real estate market with people who have taken out risky loans to get into a starter house, and if you decrease the amount they can deduct on their taxes, you may find more people in foreclosure. But likely not bankruptcy. 
Am I cynical? Yes. Under these proposals, I calculate that my taxes would go up between 10-25%. The only way I can see to take advantage of the tax proposal while continuing to live in California is to get married to someone with little or no income (i.e., the classic stay at home spouse). That would dramatically lower my taxes under this scenario, because of the increased marriage bonus. Of course, saving money on your taxes shouldn’t be the only reason to get married. Or so I’m told.
