NO

I do not see anywhere in those links that says tax deductible. 

Such a trust is not a charitable organization. It's primary purpose is to protect assets and provide for the "Special Needs" of a disabled individual, without endangering government assistance for that individual. Whenever you stop and give something to that person with the cardboard sign, you are likely contributing to a special needs individual. If they add the words "contribute to my trust" would you think it to be a valid deduction?
