The BEA budget treatment of Social Security basically remains the law to the present day. Specifically, present law mandates that the two Social Security Trust Funds, and the operations of the Postal Service, are formally considered to be "off-budget" and no longer part of the unified federal budget. (The Medicare Trust Funds, by contrast, are once again part of the unified budget.) So where matters stand presently is that the transactions to the Social Security Trust Funds and the operations of the Postal Service are "off-budget" and everything else is "on-budget."
However, those involved in budget matters often produce two sets of numbers, one without Social Security included in the budget totals and one with Social Security included. Thus, Social Security is still frequently treated as though it were part of the unified federal budget even though, technically, it no longer is.
To illustrate the difference between the "on-budget" and "off-budget" parts of the federal budget, we can observe that for fiscal year 2004 the following figures were reported by OMB:
