The Congressional Budget Office and the Joint Committee on Taxation estimate that the total net subsidy provided by the federal government for people under the age of 65 will amount to approximately $660 billion in 2016. The CBO and JCT project that this subsidy will rise annually at a rate of 5.4 percent. The forecasted net subsidy for the 2017-2026 period discussed in the report is $8.9 trillion.
Most of the costs of these subsidies can be attributed to Medicaid and to employer-sponsored health insurance coverage for those under age 65. The latter cost arises primarily because health insurance premiums paid by employers are exempt from federal income and payroll taxes. These employment-based coverage subsidies are expected to increase to $460 billion in a decade and will total around $3.6 trillion during the 2017-2026 period.
