(STILL NOT AN ACCOUNTANT). I believe the cap is not on the gift -- it's on the giver and what they have to file. There is no tax until gifts go over ~5 million.

There are two levels of exemption from the gift tax. First, gifts of up to the annual exclusion ($14,000 per recipient in 2015) incur no tax or filing requirement. By splitting their gifts, married couples can give up to twice this amount tax-free. Note that each giver and recipient pair has their own unique annual exclusion; a giver can give to any number of recipients and the exclusion is not affected by other gifts that recipient may have received from others.
Second, gifts in excess of the annual exclusion may still be tax-free up to the lifetime estate basic exclusion amount ($5,340,000 in 2014, $5,430,000 in 2015), although for estates over that amount such gifts might increase estate taxes. Taxpayers that expect to have a taxable estate may sometimes prefer to pay gift taxes as they occur, rather than saving them up as part of the estate.
For something to be a gift, the giver can have no consideration

What is considered a gift?
Any transfer to an individual, either directly or indirectly, where full consideration (measured in money or money's worth) is not received in return.
