This article summarizes the provisions of the Deficit Reduction Act of 1984 (Public Law 98-369) that relate to the Old-Age, Survivors, and Disability Insurance (OASDI) and Supplemental Security Income (SSI) programs. With regard to the OASDI program, the new law includes provisions relating to Social Security coverage of employees of the executive and legislative branches of the Government, and a provision allowing churches and church-related organizations to be exempt from Social Security employer taxes. Other OASDI provisions clarify or modify the Social Security Amendments of 1983 (Public Law 98-21). SSI program changes include provisions to increase the countable assets limit, to limit the rate of recovery for overpayments in nonfraud situations, and to waive certain overpayments that result from countable resources exceeding the applicable limits by +50 or less. The new law also contains amendments based on recommendations by the Grace Commission that will affect the administration of various programs of the Department of Health and Human Services.
