Description of Proposed Provision:
E3.16: Beginning in 2019, apply 4 percent payroll tax rate on earnings above the wage-indexed equivalent of $400,000 in 2015 (about $457,200 in 2019), with the threshold wage-indexed after 2019. Provide benefit credit for additional earnings taxed, using a secondary PIA formula. This secondary PIA formula involves: (1) an "AIME+" derived from annual earnings taxed only between 2015 wage-indexed equivalents of $400,000 and $500,000, or about $457,200 and $571,500 in 2019 (with thresholds wage-indexed after 2019); and (2) a formula factor of 2 percent on this newly computed "AIME+".

Estimates based on the intermediate assumptions of the 2017 Trustees Report
