When Congress raises the hood on the tax code, they're usually working to raise money to pay for government. But sometimes they're more interested in nudging us to behave in ways they can't legislate directly. Take the mortgage interest deduction, for example, which "cost" the Treasury $69.7 billion in 2013. That deduction encourages millions of Americans to spend billions of dollars buying homes, building homes, renovating money pits, and keeping their homes looking spiffy — all of which returns billions more through our overall economy.

Here's the catch. Everyone knows that medical and dental expenses are "deductible." But look a little closer and you'll see that code section 213 lets you deduct them only if you itemize, which leaves about 90% of Americans sitting on the bench. And even if you itemize, you can only deduct the amount of expenses over 7.5% of your adjusted gross income. So, on its face, the new deduction won't mean much.

It turns out, however, that millions of Americans who can't itemize can still benefit from tax-advantaged flexible spending accounts, medical expense reimbursement plans, and health savings accounts. The bill lets you reimburse PHIT expenses from those accounts. 

The Congressional Budget Office estimates the bill would cost the Treasury save taxpayers $3.5 billion over the next decade. That's enough to get special interests interested. The Wall Street Journal reports that "Fitbit, Inc., the American Heart Association and the American Sports and Fitness Association have all lobbied for the bill." And Planet Fitness stock climbed more than 4% the day the bill passed.
