Can I Efile IRS F8379 Colorado?

No.  You cannot include the CO Injured Spouse form with your e-filed return.   HOWEVER, you can include the federal form 8379 in your e-filed return.

The CO claim will not be reviewed unless it is mailed separately. The following information is from CO General 17-Refund Interceptions 

INJURED SPOUSE CLAIMS ON A JOINT REFUND THAT IS INTERCEPTED -When a refund is intercepted to pay a debt owed by one person on a jointly filed return, the “injured” spouse (person not in debt) can make a claim for their portion of the refund. 

Refunds are divided according to the income earned by each person of the jointly filed return. If you would like to make an injured spouse claim, you must make the claim in writing and include copies of the following documents:  

• The letter sent advising you of the intercept; 
• All W-2, W-2G, or any 1099 statements for you and your spouse; 
• A complete copy of your federal income tax return, including all schedules; and 
• IRS form 8379 for injured spouse claimed, if one was filed. 

Mail the claim to: Colorado Department of Revenue, Injured Spouse Desk Room 240, PO Box 17087,  Denver, CO 80217-0087 

• Do not attach the injured spouse claim to your individual income tax return. 
• It will not be reviewed unless mailed separately.
