Two routes still keep the check whole. If the person has an ABLE account and the need is a disability expense, which covers housing, education, transportation, health, assistive technology and more, the gift goes to the ABLE account and the person pays the shop from it. When an organization pays with PayPal Payouts, a shop without PayPal gets an email to claim the money. If nobody claims it within 30 days, PayPal returns it to the organization, not to the person, so it never becomes the person's income.
R-ABLE-01 routes the gift to the ABLE account (POMS SI 01130.740). Qualified disability expenses: IRC 529A(e)(5), listed in IRS Tax Tip 2022-112. Payouts: an item to an unregistered recipient stays UNCLAIMED and returns to the sender after 30 days.
