Summary of differences between federal and state regulations
Individual states promulgate laws to comply with the federal law — The Personal Responsibility and Work Opportunity Reconciliation Act of 1996. This act is codified at 42 USC 653-653A. Employers need to only comply with state laws.
Colorado Revised Statutes §26-13-125 requires all employers to report a newly hired employee within twenty calendar days after the date the employer hires the employee or, at the election of the employer, at the time of the first regularly scheduled payroll following the date of hire if such payroll is subsequent to the expiration of the twenty-day period.
Reports submitted magnetically or electronically must be submitted by two monthly transmissions, when necessary, and in all instances, the report shall be transmitted no more than twenty calendar days after the date of hire or, at the election of the employer, at the time of the first regularly scheduled payroll following the date of hire if such payroll is subsequent to the expiration of the twenty-day period.
