Effective July 1, 2023, employers with 25 or more employees must use E-Verify for employment eligibility verification of new employees. This verification must be done within three business days of the new hire’s start date, and employers must certify that they used the program on their first tax return of each calendar year. If an employer can’t use E-Verify, the Employment Eligibility Verification form (Form I-9) must be used and the system’s unavailability must be recorded (via screenshot, public statement, etc.). Employers cannot continue to employ someone after learning they are not eligible to work. Verification records must be kept for three years.
