At Your Service Online Unavailable for W-4 Changes

The At Your Service Online (AYSO) Tax Withholding module continues to be closed until programming to incorporate substantial IRS 2020 W-4 changes has been completed. We do not have a date at this time as to when the module will reopen.

During this outage period, the Payroll Office will be unable to process paper W-4 forms to update tax withholding for 2020. Once AYSO is available for W-4 updates, employees will be notified via email by UC Office of the President to log in and make changes.

Please consult the following information for guidance on specific employee needs.

  • Existing employees who want to change their withholdings will have their previous status from 2019 remain in effect until updates have been completed in our payroll system. Upon notification, employees may change their elections in AYSO directly.
  • New employees hired on or after January 1, 2020 will default to Single status. Upon notification, employees may change their elections in AYSO directly.
  • Employees who claim exemption from tax withholding must renew their exemption by February 7, 2020. If they chose to do so before the AYSO module reopens, they will need to provide the 2020 W4 to the Payroll Office to claim exemption.
  • Nonresident aliens claiming tax treaty exemption or renewing their tax treaty exemption because it expired should work with the Glacier Admin.

If you had previously submitted a paper Form W-4 for 2020 or a paper Form DE-4 for the State of California to the Controller's Office Solution Center, the Payroll Office will hold the form and process once system updates are complete and AYSO is back online.

FAQs on the new W-4 form are available on the IRS website at: Please contact the Controller's Office Solution Center if you have questions.
