You may have your 2015 RMD made payable directly to the charity (provided it meets the IRS definition of a qualified charity), and then designate it as a qualified charitable distribution on your tax return. You'll have satisfied your distribution requirement, and you won't have to pay income taxes on that money.
Actually, yes. In 2006 and 2007, investors age 70 1/2 and older are allowed to make tax-free direct transfers to a public charity. You will be able to transfer up to $100,000 annually, and your RMD can be satisfied by this gift as a Qualified Charitable Distribution.
