Social Security back pay rules provide lump-sum retroactive benefits for past-due amounts, primarily for SSDI (Disability Insurance) and some retirement/survivor claims, based on the disability's onset date or application date, with a mandatory 5-month wait for SSDI before benefits are payable (though you can get up to 12 months retroactively before the application date if the disability started early enough). SSI (Supplemental Security Income) has different rules, usually only paying from the application date forward, with no retroactive period or 5-month wait. The payment arrives in one lump sum, separate from ongoing monthly benefits, and affects taxes.
