Back Pay (SSI)
Retroactive SSI payments owed to an approved claimant from the date of their application (or protective filing date) through the month of approval.
Unlike SSDI, SSI back pay exceeding $5,445 (3x the maximum monthly SSI amount) must be paid in installments every 6 months. Installment rule exceptions apply if you have an immediate large expense (e.g., housing). SSI back pay does count as a resource for 9 months — you must spend it within that window to protect ongoing eligibility.
→ Depositing SSI back pay into an ABLE Account is one common strategy to protect it.
