Proposed Provision: Eliminate the taxable maximum in years 2018 and later. Phase in elimination by taxing all earnings above the current law taxable maximum at 2.48% in 2014, 4.96% in 2015, up to 12.4% in 2018 and later. Credit the additional earnings for benefit purposes by: (a) calculating a second average indexed monthly earnings (AIME+) reflecting only earnings taxed above the current law taxable maximum, (b) applying a 5 percent factor on this newly computed AIME+ to develop a second component of the PIA, and (c) adding this second component to the current-law PIA.
