My husband had to accept a disability retirement last year. He is only 53, but glaucoma has now prevented him from keeping his job and driving. He collects a disability pension from the State of CT. I work full time and part time. We have a 16 year old daughter. Can I now file as head of household and will this aid us in our taxes if we do file this way? Our approximate combined income will be about $80000 this year, about 25,000 less than last year.
