Dozens of Federal Tax Breaks Set to Expire

But may be renewed retroactively, as they are every year, creating all sorts of business uncertainty

In an almost annual ritual, Congress is letting a package of 55 popular tax breaks expire at the end of the year, creating uncertainty — once again — for millions of individuals and businesses.

Lawmakers let these tax breaks lapse almost every year, even though they save businesses and individuals billions of dollars. And almost every year, Congress eventually renews them, retroactively, so taxpayers can claim them by the time they file their tax returns.

No harm, no foul, right? After all, taxpayers filing returns in the spring won't be hurt because the tax breaks were in effect for 2013. Taxpayers won't be hit until 2015, when they file tax returns for next year.
