The financial condition of the Social Security and Medicare programs remains challenging. Projected long run program costs are not sustainable under current program parameters. Social Security's annual surpluses of tax income over expenditures are expected to fall sharply this year and to stay about constant in 2010 because of the economic recession, and to rise only briefly before declining and turning to cash flow deficits beginning in 2016 that grow as the baby boom generation retires. The deficits will be made up by redeeming trust fund assets until reserves are exhausted in 2037, at which point tax income would be sufficient to pay about three fourths of scheduled benefits through 2083.
