The TaxBandits API supports the automation of Forms UITR-1 and UITR-1A, Colorado's UI wage and premium reports.

Key compliance notes​

  • Zero filing required. Forms UITR-1 and UITR-1A must be filed every quarter, even if no wages were paid.

Before filing, you can simulate the entire verification flow in our Sandbox environment without submitting real data to state agencies. See how

Common endpoints (utility)​

These endpoints share the same payload structure across all states, and apply uniformly whether you're working with a withholding form or a UI form:

  • List: Retrieves a list of forms created for a specific business or period.
  • Delete: Removes an in-progress form before it's transmitted to the state.
  • Transmit: Submits a completed form to the corresponding state agency.
  • RequestPdfUrls: Returns a link to download the PDF version of a form (final).
  • Status: Checks whether a submitted form was accepted or rejected by the state.

As an alternative to polling the Status endpoint, you can configure a webhook for the event type Status Payroll Filings Status Change to receive automated status updates.
