Cap on Deductions Won't Hurt My Giving 'by a Penny': Buffett

Buffett: 'No Question' Global Economy Is Slowing

With "fiscal cliff" discussions going on in Washington, non-profits are already in combat mode over the potential for a cap or limit on charitable tax deductions.

But America's Philanthropist-in-Chief (or Vice Philanthropist, next to Gates) says that doing away with the charitable deduction altogether wouldn't change his giving – not even by a penny.

"If there were no deduction allowed it would not change my charitable giving a penny," Buffett said on CNBC's Squawk Box this morning. (Read more: Would Fiscal Cliff Keep Rich From Giving to Charity?)

Of course, Buffett's finances, and his use of deductions, is different from most of the rich – and even the super-rich. Buffett said that because he gives away billions a year, he has a $10 billion "charitable deduction carry forward" that he can never use.

"I don't get the deduction on virtually everything I give away," he said. "I get to take a deduction for less than one percent of the value of what I give away every year."

He said that the same is true "for a number of wealthy people, but there are some other people that it's not true of." (Read more: The Hitch in Buffett's Tax Plan)

In sum, everyday millionaires and even billionaires may reduce their giving with the charitable deduction limit. But at least Buffett will keep giving – and that's no small thing.
