How do I deduct the military's spouse's income on the Connecticut return?

According to the CT Department of Revenue, "If the servicemember’s domicile is in Connecticut, the military spouse does not qualify for exemption from Connecticut income tax under the MSRRA. Servicemember who is not a Connecticut domiciliary: For Connecticut income tax purposes, a military spouse is considered a nonresident of Connecticut if the servicemember and the military spouse have the same domicile outside of Connecticut and the military spouse is in Connecticut solely to be with the servicemember who is serving in compliance with military orders."

How do I claim tax-exempt from Connecticut withholdings?

If you meet the requirements to claim exempt status from CT withholding, complete Form CT-W4. Enter Withholding Code “E” on Form CT-W4, Line 1.  Provide Form CT-W4 to your employer.  You must provide your employer with a copy of your military spouse’s Leave and Earnings Statement (LES) and a copy of your military spouse ID card.  

Military spouses claiming exemption from Connecticut income tax under the MSRRA may be required to provide proof that he or she qualifies for the exemption.
