W-2 Information

UC Davis employees are encouraged to receive their W-2 tax form electronically.

With both AYSO and UCPath W2 reporting complete, it is a good time to remind ourselves of the proper way to report the two W2s on our income tax returns.   One of the benefits of UCPath is the ease of tax administration for the UC System, which is accomplished by migrating the entire UC System to a single employer identification number. This year, each W2 will need to be reported separately on individual tax returns using the employer identification numbers reported in box 13(b) for Federal wages and box 15 for state wages. 

The IRS matches wages reported by employers using the employer identification number.     Failure to separately report the W2s by the respective employer identification numbers will likely generate automated IRS notices to employees. 

W-2 forms will be provided electronically in late January on the At Your Service Online (AYSO) Web site for employment through September 2019, and on UCPath Employee Portal for October to December 2019. The 2019 tax year is the only year that employees may need to access two W-2 tax forms from UC Davis to report their earnings.
