Employment Verification Law

The Colorado Employment verification law (8-2-122, C.R.S.) and rules apply to public and private employers who transact business in Colorado, and to employees hired on or after January 1, 2007.


There are two main components to the law:

(1) Each employer in Colorado shall make an affirmation within 20 calendar days after hiring a new employee. The employer must keep a written or electronic copy of the affirmation for the term of employment of each employee. 

(2) The employer must keep a written or electronic copy of the employee's documents required by 8 U.S.C. sec. 1324a (commonly known as Form I-9 identity and employment authorization documents). The copies must be retained for the term of employment of each employee.

Employers must use the Division Mandatory Affirmation Form with a revision date of 09/01/14 for all employees hired after October 1, 2014.  This form may also be used for all employees hired on or after September 1, 2014.

The documents described above should not be submitted to the Colorado Division of Labor, unless specifically requested by the Division.
