And what else was in the Fiscal Cliff deal"?

The questions are already rolling in: Why did my pay drop? Tax policy can be complex and overwhelming and for most Americans it boils down to what they see on their paystub. Most will see their pay drop by about 2 in 2013 due to the expiration of the payroll tax holiday as part of the Fiscal Cliff deal. Heres how.
What is the payroll tax?
Appearing on many paystubs as FICA Med-FICA OASDI Social Security or Medicare most Americans have 6.2 of their paychecks withheld to fund Social Security (payments to retired and disabled individuals) and another 1.45 withheld to fund Medicare (health care for the elderly) for a combined 7.65.
Employers also contribute an additional 7.65. Together these taxes raise nearly $1 trillion per year.
What was the Payroll Tax Holiday"?
The Payroll Tax Holiday was enacted in 2011 which reduced the employee share of the Social Security payroll tax from 6.2 to 4.2. The holiday was not renewed when it expired at the end of 2012.
The Payroll Tax Holiday replaced the previous Making Work Pay tax credit which itself was adopted in 2009. That credit refunded 6.2 of a taxpayers earnings up to $400 ($800 for a married couple) with the credit phased out for those earning over $75000 ($150000 for a married couple) and eliminated entirely for those earning over $95000 ($190000 for a married couple).
Put succinctly the credit refunded the Social Security tax paid on income up to $6500 for all but high-income earners.
The credit was also refundable meaning that those with no tax liability could still receive the credit.
Why did the payroll tax holiday expire?
The Payroll Tax Holiday proved popular with taxpayers … but costly reducing federal revenues by some $10 billion per month. U.S. payroll taxes also fund some of our largest entitlement programs so reducing them potentially aggravated the long-term solvency of Social Security.
Proponents of the holiday argued that it boosted spending; experts continue to debate the effect on the economy of such short-term stimulus proposals.
Proponents also stated that the federal government would make up Social Securitys lost revenue although the federal government has no budget surplus to do so. The holiday therefore meant larger federal government borrowing at a time of record deficits.
Who is affected by the payroll tax holiday expiration?
All Americans who earn wage income pay payroll taxes. While the fiscal cliff deal debate focused on how much higher taxes on wealthy Americans would be most Americans will see a tax increase because of the payroll tax holiday expiration.
