Deductions & credits

You can't just "deduct" it -- there is nowhere on the current forms to do this. I don't think I would just subtract 10,200 on my own from the reported income.  I would wait to see what the IRS says to do.  The bill just got passed, so it's not like they are going to issue instructions the next day.   Remember that millions of taxpayers (and accountants) are asking the exact same question.
