PR13 Withholding of Federal Income Tax

Policy Status: 


Policy Steward: 

Corporate Controller / Payroll



To outline the Internal Revenue Services Federal Income Tax withholding requirements which affect the University and its employees.


Federal earned income tax is withheld on a graduated scale from an employee's gross pay, the applicable percentage being determined by the amount of the employee's earnings.


An employee with excess itemized deductions may be entitled to claim additional withholding allowances. These allowances are determined by using the Worksheet to Figure Your Withholding Allowances. The Worksheet and instructions are available from your Human Resources Representative.


Employees desiring to have more than the maximum standard deduction withheld must use the Worksheet and the Instruction sheet, step 4, to determine an additional dollar amount of withholding. The computation would be transferred to the W-4.


See International Information for specific information concerning withholding of Federal Income Taxes and Internal Revenue regulations which apply to foreign nationals.


For questions, additional detail, or to request changes to this policy, please contact the Payroll Office.
