On Dec. 31, the George W. Bush-era tax cuts are scheduled to expire, raising rates on investment income, estates and gifts, and earnings at all levels. Overnight, the marriage penalty for joint filers will spring back to life, the value of the child credit will drop from $1,000 to $500, and the rate everyone pays on the first $8,700 of wages will jump from 10 percent to 15 percent.
The Social Security payroll tax will pop back up to 6.2 percent from 4.2 percent under the deal approved Friday by Congress. And new Medicare taxes enacted as part of President Barack Obama's health-care initiative will for the first time strike high-income households.
Obama and congressional Republicans say they hope to avert the coming blow, which stands to suck roughly $500 billion out of the economy in 2013.
