Federal and State Income Tax Changes
Effective April 1, 2009, the federal withholding tables changed due to the American Recovery and Reinvestment Act of 2009.
To get more information and verify you do not have too much or too little federal income tax withheld from your pay, use the IRS withholding calculator.
A new law (AB X3 3 Ch. 18 2009) raised state personal income tax rates and reduced the dependent exemption credit for the 2009 calendar year.
The new state withholding tables factor in changes for the tax rate increase only, so taxpayers claiming dependent exemption credits may need to modify their state withholding.
