Richard L. Kaplan (Illinois) has published Rethinking Medicare’s Payroll Tax After Health Care Reform, 90 Taxes 55 (Aug. 2011). Here is the abstract:

This Article addresses the significant changes to the Medicare tax that were enacted in the 2010 health care reform legislation. Effective in 2013, these changes apply to anyone, retired or not, whose adjusted gross income exceeds $200,000 (or $250,000 for a married couple filing jointly) and apply to investment receipts as well as salary and self-employment income. The Article briefly explains how Medicare is financed currently and then focuses on the new changes, analyzing their impact on two-income married couples, the interaction of the increased tax on salaries with the new tax on investment income, and the effect of mandatory pension plan distributions. The Article then considers whether in light of these new changes, there is any continuing rationale for dedicated taxes that fund the Medicare program.
