A Colorado state refund for non-residents occurs when the total amount of tax withheld from payments received from a Colorado-based employer or source is greater than the actual tax liability determined by the the Colorado Department of Revenue. This is typical for individuals who work remotely or maintain a temporary residency status while performing services within the state's borders.
The primary mechanism for recovery is the submission of a Colorado Form DR 0104 own non-resident return. By calculating the proportion of Colorado-sourced income relative to total income, the amount of tax owed to the state is recalculated. If the withholding exceeds this calculated liability, the state issues a refund check or direct deposit to the taxpayer.
