Employer Sponsored Health Coverage W-2 Reporting

Under the Affordable Care Act (ACA), employers are required to report on Form W-2 the cost of coverage under an employer-sponsored group health plan. This item will be part of your 2018 W-2 Form, reported in Box 12DD. This amount is included for informational purposes only; it is not taxable. Learn a full overview of Stanford W-2 Forms.

In addition to the W-2 Form, in compliance with the ACA, Stanford will issue a Form 1095 that reports the medical coverage made available to you by Stanford in 2018.
