Why do I have to sign Colorado form DR 8453 if I don’t need to mail it ?

[AnthonyC · Accepted solution]

Colorado, along with quite a few other states, maintains this technical requirement to sign and date Form 8453 for your records only when e-filing.  It helps creates a paper trail of your electronic filing.
