Can having dementia be considered 100% disability?

DFleming, talk to your local assessor's office about what tax exemptions are available, such as veterans, old age, low income and disability. They will have forms for you to fill out and be signed by the MD. Also talk this over with the person who does your federal and state tax returns.

I should add that I know a married couple in my county. The wife has Parkinson's. They were able to qualify for total exemption even though their income was more than $12K based on her disability.

I live in Birmingham, AL, and was able to get total disability for my mother for property tax purposes. To qualify, she had to get letters from two separate doctors about her condition. I took her the letters and her tax returns into the property tax office.

It turned out she also qualified because her gross income was less than $12K a year. It is nice that we don't have to get letters from doctors each year. We just have to show she is poor by showing her tax returns. Areas differ in their requirements for exemption. You may want to call your county office to talk to them about specific requirements and what you need to apply for exemption.
