2023 Tax Data Submission

All Colorado PERA employers must submit their W-2, W-3, 1096, and 1099-NEC/MISC files to PERA on an annual basis. These files must be submitted for any individual or firm that has provided services to the employer.

For your convenience, PERA has the same formatting and submission requirements as the Social Security Administration (SSA) and the Internal Revenue Service (IRS). The file format is as follows:

PERA prefers and encourages use of the Secure Transfer and Reporting System (STARS) for the transmission of all W-2, W-3, 1096, and 1099-NEC/MISC files. This is a safe, secure way to transfer this data. STARS can be found in the employer access section of PERA’s website at

Only authorized users can access STARS. If the person doing your submission this year is the same as last year, PERA does not require new user approval. If you need to authorize a new user or need a separate authorization for this process, please contact your PERA Employer Representative.

Important Information About Submitting W-2, W-3, 1096, and 1099-NEC/MISC Files:

  • If your department has 250 or more W-2, W-3, 1096, or 1099-NEC/MISC files, you MUST submit your files using STARS. There are no exceptions to this requirement.
  • If you use an outside payroll service to file your tax forms, please make arrangements with the service in advance to have your files submitted through STARS.
  • If you have less than 250 W-2, W-3, 1096, or 1099-NEC/MISC files and you do not file electronically with PERA:
    • Your files may be uploaded as a PDF document(s) through STARS.
    • For security purposes, PERA will only accept paper W-2, W-3, 1096, and 1099-NEC/MISC files through standard mail, courier, or hand delivery to the PERA front desk. There are no exceptions to this requirement.
  • If you do not file any 1099-NEC/MISC forms for the 2023 tax year, please notify PERA so we may provide you with a form to complete which certifies you did not file any 1099-NEC/MISC tax forms.

The deadline for submission of these reports is March 31, 2024. If you have already submitted your 2023 tax data information, thank you for your continued partnership in meeting this requirement.  If you haven’t submitted your files, please do so as soon as possible.
