The Tax Foundation:  “In order to finance $940 billion in new health care spending over the next ten years, the health care bill that the House of Representatives passed on Sunday evening contains many spending cuts to Medicare, along with many tax increases that are set to go into effect over the next decade. Courtesy of the Joint Committee on Taxation’s scoring of each of the provisions in the bill and the CBO, this Tax Foundation Fiscal Fact contains a timeline of when each of the tax provisions in the bill is set to go into effect. Note this list includes provisions in the reconciliation bill combined with the Senate bill and not just the Senate bill that Pres. Obama will sign into law this week.”

“Some of the minor provisions are actually retroactive, whereas others such as the tax on high-cost health insurance plans (the so-called “Cadillac tax”) don’t go into effect until 2018. The increased Medicare tax that would for the first time expand part of payroll taxes to investment income, as well as incorporate filing status into a tax unit’s liability, would go into effect in 2013.  All starting dates are January 1 of that year, unless otherwise noted. This list is fairly exhaustive, meaning it includes virtually every tax provision. The major provisions, as defined as those projected to raise or lose more than $10 billion within the ten year budget window, are denoted in red.”
