About IRS Form W-2

Last updated Wednesday, November 10, 2021

The IRS Form W-2 Wage and Tax Statement (PDF) reports all taxable wages paid to and taxes withheld from an employee during the calendar year, from the January 10 payday through the December 25 payday. It includes details of employee and employer contributions to a variety of tax-related benefits such as retirement and savings plans, medical and dental, flexible spending account and others.

The Federal Affordable Care Act (ACA) also requires employer‐sponsored medical and dental costs to be reported on both the W-2 and 1095 forms.

W-2 Frequently Asked Questions

The ISC mails paper tax forms on January 25 each year. Mail may take several business days to arrive. If you feel enough time has passed for delivery and you still haven’t received your tax forms, first verify your designated mailing address in Workday. If your address was incorrect or if your tax forms were lost in the mail, you will need to access your tax documents online in Workday following the steps above.

Refer to the Accessing Prior Year Tax Forms section of the Year End Tax Resources page.

Your one University of Washington W-2 reflects your wages and taxes paid for ALL of your positions at the University of Washington, UW Medical Centers and Harborview.

At the University of Washington, a Stipend is an Earning Type used to pay a scholarship or fellowship. There are three Stipend Earning Types used by the University: STP, SFP, and SWB. Stipends are not considered wages, so are not reported on the W-2. However, that does not mean that the Stipend isn’t taxable. Student Fiscal Services (SFS) assess UW Stipend Earnings. For students, any stipend earnings are reported on Form 1098-T. Non-students will receive a Stipend Letter, mailed in late January.

If your name and/or SSN in Workday does not match up with the information on your Social Security card, you will need to submit a copy of your Social Security Card to the ISC’s Payroll department, either in person at the ISC (UW Tower, Floor O-2) or via secured fax line at 206-543-8137 (important security note: please do not ever include your Social Security Number in an email). Once the information is validated, the ISC will make any necessary corrections.

Box 1 is your reportable taxable income for the calendar year, and is the amount you will enter on the wage line of your tax return per IRS rules; it includes your gross wages minus any pre-tax items such as medical and health premiums, FSA/DCAP contributions and retirement amounts. Box 3 is the amount of your total reportable wages subject to Social Security taxes; retirement plans are not considered pre-tax items for the purposes of Social Security, so Box 3 may be larger than Box 1. Box 5 is the amount of your total reportable wages subject to Medicare taxes; as there is no cap for Medicare taxes the way there is for Social Security taxes, Box 5 may be larger than Box 1 and Box 3.

Box 1 is not usually the same as your gross wages; it is simply the amount of your taxable wages, as determined by the IRS. Box 1 will not include amounts such as your pre-tax benefits, elective deferrals, mandatory retirement contributions or any other amount not subject to taxes.

Box 2 is the amount of Federal Withholding Tax you chose to withhold from your paychecks when you completed your W-4 during the onboarding process. Each employee determines their own amount of withholding. If Box 2 is empty on your W-2, it means either you claimed exempt on your withholding or your calculated withholding elections exceeded your salary, so no amount was withheld from your paychecks.

You can update your withholding elections at any time; for guidance, visit the Update Federal Withholding Elections User Guide.

Many student employees are exempt from paying Social Security and Medicare taxes and their earnings aren’t subject to tax. Box 3 and Box 5 will be empty or reduced if you qualified under these student FICA exemption rules.

You can find more information about student exemptions on the Tax Office’s FICA page, as well as in the Calculating Federal FICA and Other Mandatory State Taxes section of the ISC’s Tax Withholding Information For US Citizens page.

Box 3 is the amount of your total reportable wages subject to Social Security taxes. Box 5 is the amount of your total reportable wages subject to Medicare taxes. As there is no cap for Medicare taxes the way there is for Social Security taxes, Box 5 may be larger than Box 3.

The IRS had included Box 9 on the W-2 as part of a “Verification Code” pilot program. However, because of new wage and income reporting requirements, the IRS has discontinued the pilot for the 2019 tax year – as a result, Box 9 is no longer used.

The IRS requires employers to include the cost of employer-sponsored health coverage on the employee’s W-2. This amount is reported with Code DD. This amount is not taxable.

Box 12 includes the amount of elective deferrals and various other types of compensation. The IRS has not designated an official code for mandatory contributions to retirement plans, and therefore the amount would not be displayed in Box 12. Additionally, because contributions to UWRP are considered mandatory contributions and not elective deferrals, UWRP contributions have been taken into account in Box 1 and are not itemized in Box 12. Your year-to-date totals can be found on your payslip.

*On March 17, 2021, the IRS amended their guidance issued in January 2021 on how employers should report sick and family leave wages paid under the Families First Coronavirus Response Act (FFCRA).

Previously, employers were to report qualified FFCRA wages paid in 2020 in Box 14 of the 2020 Form W-2; employees who had qualified FFCRA wages paid in 2020 would have seen FFCRA amounts listed in Box 14 on the 2020 Form W-2 made available in January 2021.

However, in April 2021, in accordance with the new IRS guidelines, employees who had qualified FFCRA wages paid in 2020 were sent revised Form W-2s that display zero for FFCRA wages in Box 14 of the 2020 Form W-2.
