A qualified disability trust is any trust:
Described in 42 U.S.C. 1396p(c)(2)(B)(iv) and established solely for the benefit of an individual under 65 years of age who is disabled, and
All of the beneficiaries of which are determined by the Commissioner of Social Security to have been disabled for some part of the tax year within the meaning of 42 U.S.C. 1382c(a)(3).
A trust will not fail to meet item 2 above just because the trust's corpus may revert to a person who is not disabled after the trust ceases to have any disabled beneficiaries.
