Yes, it should be treated as a grantor trust since even though the parents are the “grantors” on the trust document, the trust is funded with the child’s money, so they are the grantor for tax purposes. This will not affect the child’s eligibility for public benefits because the definition of “income” for tax purposes is different from its definition for public benefits eligibility determinations. For the latter, only income that is actually distributed to the beneficiary counts.
