The two Social Security trust funds and the postal service are “off-budget”—their spending and receipts are walled off from the rest of the budget. Putting Social Security and the post office off-budget shields them from some pressures, but policymakers often focus on the unified budget that includes them. A few other agencies are excluded because of their independence (e.g., the Federal Reserve) or private character (e.g., government-sponsored, privately owned entities and funds managed for private citizens).
Off-Budget versus On-Budget Accounting
The budget brings together the spending and receipts of virtually all federal activities, from paying doctors who treat Medicare patients to financing the Environmental Protection Agency to collecting income taxes to selling oil leases on federal land. In two cases, however, Congress has separated programs from the rest of the budget. The Postal Service Fund and the disability and retirement trust funds in Social Security are formally designated “off-budget,” even though their spending and revenues are included in the unified budget.
Lawmakers created this special accounting to try to wall off these programs. For the postal service, the intent was to free the agency to pursue more efficient practices than the conventional budget process allows. But that has not helped the postal service avoid financial difficulties.
With Social Security, the intent was to protect any surpluses from being diverted into other programs. The two Social Security trust funds have accumulated large surpluses since 1983. Those balances would eventually be drawn down to pay benefits, as is happening today. Advocates therefore argued that those surpluses should be separated from budgeting for the rest of government. Congress hoped that this separation would induce greater fiscal discipline in the rest of the government.
RESULTS
This accounting has had mixed results. Congressional budget rules prevent spending reductions or revenue increases in Social Security from being explicitly used to pay for spending increases or tax cuts elsewhere. In that sense, off-budget accounting has protected the program. But high-level budget discussions focus on the unified budget deficit and thus ignore the off-budget versus on-budget distinction. As a result, past Social Security surpluses have effectively helped finance deficits elsewhere in the government. Just how much is unclear, but in the three decades that Social Security has been off-budget, the rest of government has run a surplus in only two years (1999 and 2000).
In any case, these arguments have less relevance today. Annual Social Security expenditures have exceeded noninterest income since 2010. Combined trust fund expenditures began to exceed all income in 2021. As a result, the combined trust fund balance has begun to decline.
The Federal Reserve System
The Federal Reserve System (the Fed) is part of the federal government but is explicitly excluded from the budget to shield monetary policymakers from political pressure. Other developed nations do the same. The Fed thus sets its own spending and finances itself from earnings on lending to banks and its financial assets. The Fed remits any profits to the Treasury each year, which the budget records as receipts, but the agency otherwise operates outside the budget.
OTHER ACTIVITIES OUTSIDE THE BUDGET
Some federal activities are outside the budget because the government plays a limited role in what is otherwise a private activity. The government manages various funds whose assets belong to Indian tribes, federal employees, copyright holders, and other private individuals. Spending from and receipts to those funds are generally not included in the budget.
Government-sponsored enterprises, such as the Federal Home Loan Banks, also fall outside the budget because they are privately owned and their debt does not bear the full faith and credit of the US government. However, most observers assume their close ties to the government would lead to a bailout if they got into financial trouble.
That assumption proved accurate for Fannie Mae and Freddie Mac, the giant mortgage finance enterprises. During the 2008 financial crisis, they received substantial financial assistance and were put into federal conservatorship. This has led to a dispute regarding their status. The Office of Management and Budget believes Fannie Mae and Freddie Mac are still sufficiently private to fall outside the budget. The Congressional Budget Office believes federal control is now so strong that the two entities are effectively federal agencies and their spending and receipts should be in the budget.Government-sponsored enterprises, such as the Federal Home Loan Banks, also fall outside the budget because they are privately owned and their debt does not bear the full faith and credit of the US government.
