More than 71 million Americans rely on Social Security benefits each month, and for many recipients, December payments are already arriving. As the year winds down, beneficiaries are also looking ahead: after the final December disbursements, there will be only one remaining round of disability payments and one more Supplemental Security Income (SSI) check issued before 2025 officially ends.
