Public Good IRA Rollover Act of 201 7 This bill amends the Internal Revenue Code to revise the tax exclusion for distributions from individual retirement accounts (IRAs) for charitable purposes to: (1) eliminate the $100,000 cap on such exclusion; (2) permit tax-free distributions from IRAs to a split-interest entity (i.e., a charitable remainder annuity or unitrust, a pooled income fund, and a charitable gift annuity); and (3) allow distributions to a split-interest entity to be made when the account beneficiary attains age 59-1/2 (otherwise, age 70-1/2 for IRA distributions to a charitable organization).
