This report analyzes 36 policy options that are among those commonly proposed by policymakers and analysts, presenting their effects on the Social Security System’s finances and on people born at various times and with different amounts of earnings. Although most of the options would improve Social Security’s long-term finances, only a few would significantly postpone the combined trust funds’ exhaustion date. No individual option by itself could create long-term stability for the Social Security program.

In the Department of Defense, civilian workers in the support occupations that CBO analyzed cost the government as a whole about 30 percent less, on average, than military personnel. Consequently, the department could reduce federal costs by replacing some military personnel in support positions with civilian employees. If it replaced 80,000 military personnel in nondeploying units, it could eventually save $3.1 billion to $5.7 billion annually, depending on how many civilians would be required to replace them.

In 2016, low- and moderate-income workers will face an effective marginal tax rate of 31 percent, on average. Federal individual income and payroll taxes will be the main contributors; that estimate also takes into account state individual income taxes and the phaseout, at various income levels, of the Supplemental Nutrition Assistance Program and the cost-sharing subsidies for health insurance. That rate will vary greatly by people’s income and other, nonfinancial characteristics.
