Employer New Hire Reporting

State Directory of New Hires (SDNH) is a centralized, confidential, and secure repository responsible for receiving new hire data reported by employers in the State of Colorado. Federal law (42 USC 653A(b)(1)(A)) requires employers to furnish this data to the SDNH of the state in which a newly hired employee works.

  • This reporting must take place within 20 calendar days after the date of hire or by the first regularly scheduled payroll following the date of hire, if such payroll is after the expiration of the 20-day period.
  • If reporting electronically, the employer must transmit twice per month, no fewer than 12 and no more than 16 days apart.

"Employer" has the same definition as for federal income tax purposes. Employers required to provide employees with W-2 forms must also comply with new hire reporting requirements.
