If your withholding allowances have changed, please remember to file an updated W-4 in order to ensure that the appropriate amount of withholding taxes are deducted from your paycheck. You may update your W-4 by submitting a new Form W-4 to the Employee Services Center for TTU/TTUSA. TTUHSC employees please send to TTUHSC HR.

Please contact Payroll Services at webmaster.payroll@ttu.edu or 742-3211 with any questions.
