A Colorado law, § 8-2-122, C.R.S., concerning employment verification requirements became effective on January 1, 2007. This law applies 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 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. A sample affirmation is available below.

(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.

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

Effective October 1, 2012, Colorado employers must use the Division affirmation form with a revision date of 09/06/12 for all new hires.
