Here's something you wouldn't expect: Your Federal Taxes Withholding MAY be going up in 2011

[RobertSeattle]

If you make under $75,000, you Federal Income taxes are going up! It has to do with the "Making Work Pay Tax Credit" that expired 12/31/2010. If you make under 75K, your withholding will actually be going up with your first paycheck in 2011 assuming you didn't have a salary change.

Yes, your SSN tax will be going down by 2% points, but due to changes in the withholding tables, you Federal Tax withholding will actually increase with your first paycheck in 2011. You'll still have a net increase in take home, but it came as a surprise when I did our company's payroll, and everyone who made under 75K got an increase in their withholding.
