Social Security Number Truncation on Form W-2

On July 31, 2019, the IRS issued its final rule allowing employers to voluntarily truncate Social Security numbers on copies of Form W-2 issued after December 31, 2020. Upon review, and in order to provide greater protection against identity theft, the University of Arizona has opted to truncate social security numbers on all Form W-2s issued to employees.

Social Security Number truncation (masking) will be in place starting with 2020 W-2s delivered in calendar year 2021.
