To claim Colorado residency, the customer must hold a valid Colorado Driver's License or Colorado Identification Card for a minimum of six months. The physical residence address provided to buy or apply for a license must be the same as the address given for Colorado state income tax purposes.
Identification Issued Less Than Six Months Ago
If your Colorado driver's license or Colorado identification card was issued or renewed less than six months ago you must provide additional documentation of at least two sources from the below list to prove that you have been a resident for the required six months.
The additional proofs of residency must have your name and Colorado residency address on them and provide proof that you have lived in Colorado each of the prior six consecutive months. For example, you could provide six consecutive months worth of electric bills and six consecutive months worth of rent receipts in addition to your Colorado driver's license and ID.
Owning property in the state of Colorado does not establish residency.
