Proposed Provision: E2.11. Eliminate the taxable maximum in years 2022 and later. Phase in elimination by taxing all earnings above the current-law taxable maximum at: 2.48 percent in 2018, 4.96 percent in 2019, and so on, up to 12.40 percent in 2022. Provide benefit credit for earnings above the current-law taxable maximum that are subject to the payroll tax, using a secondary PIA formula. This secondary PIA formula involves: (1) an "AIME+" derived from annual earnings from each year after 2017 that were in excess of that year's current-law taxable maximum; and (2) a formula factor of 5 percent on this newly computed "AIME+".
