Information is available on federal tax withholding as a result of the American Recovery and Reinvestment Act of 2009. The IRS has subsequently issued additional information encouraging employees in certain categories to review their withholding to determine if enough tax is being withheld. Faculty and staff are encouraged to seek advice from their personal tax accountant or go to http://www.irs.gov to use the online withholding calculator to determine if it is necessary to file a revised W-4 to ensure adequate wage withholding to meet their estimated income tax liability.
