I learned at the 45th Annual CLEW Tax workshop that on March 10, 2011, Senator Charles Schumer (D-NY) introduced the Public Good IRA Rollover Act of 2011 (Senate Bill 557 or H.R. 2502). Under the proposal the income tax exemption would become permanent, apply to people 59 1/2 years of age (instead of 70 1/2), remove the $100,000 cap, and allow rollovers to donor-advised funds, supporting organizations, and private foundations.
Currently the legislation is stuck in committee and is not moving forward. Please check back in the future for updates.
