Am I required to keep I-9 forms for three years or one year?

There is a lot of confusion surrounding the requirements of I-9s. You must retain the I-9s as long as the individual works for you. Once the individual quits/is terminated, an employer is required to keep I-9s for the latter of three years from the hire date or one year after termination.

For example, if an employee works for one year and quits/is terminated, the employer will be required to keep his/her I-9 for another two years — three years from the hire date. If the employee has worked for several (for e​xample, 10) years and quits/is terminated, the employer must keep his/her I-9 for one more year.
