The federal government will receive $3.422 trillion in revenue. Most of the taxes are paid by you, either through income or payroll taxes:
- Income taxes contribute $1.622 trillion, or 49 percent of total receipts.
- Social Security, Medicare, and other add $1.238 trillion, or 36 percent.
- Corporate taxes supply $225 billion, or 7 percent.
- Excise taxes and tariffs contribute $152 billion, or 4 percent.
- Earnings from the Federal Reserve's holdings add $55 billion, or 2 percent. Those are interest payments on the U.S. Treasury debt the Fed acquired through quantitative easing.
- Estate taxes and other miscellaneous revenue supply the remaining 2 percent.
It's estimated that each taxpayer works until late April each year to pay for all federal revenue collected. That's Tax Freedom Day. Can you think of any other purchase you make for which you've worked as hard and long?
The government will spend $4.407 trillion. Most of this (62 percent) pays for mandated benefits, such as Social Security, Medicare, and Medicaid.
Interest on the U.S. debt is $363 billion. The U.S. Treasury must pay it to avoid a U.S. debt default. The United States has been fortunate because interest rates have been low. A worldwide flight to safety increased demand for Treasury notes, lowering rates. Now that the global economy is strengthening, Treasury yields are rising. So will interest payments. Interest on the $21 trillion debt is already the fastest growing federal expense.
The remaining 38 percent of the budget pays for everything else. It's called discretionary spending. The U.S. Congress changes this amount each year. It uses the president's budget as a starting point.
Mandatory spending is $2.739 trillion. Social Security is by far the biggest expense, at $1.046 trillion. Medicare is next, at $625 billion, followed by Medicaid at $412 billion.
Social Security costs are currently covered 100 percent by payroll taxes and interest on past that have been invested. Until 2010, there was more coming into the Social Security Trust Fund than being paid out. Thanks to interest on investments, the Trust Fund is still running a surplus. But, the Trust Fund’s Board estimates that this surplus will be depleted by 2036. Social Security revenue, from payroll taxes and interest earned, will cover only 77 percent of the benefits promised to retirees.
Medicare is already underfunded. Medicare taxes don't pay for all benefits, so this program relies on general tax dollars to pay for a portion of it. Medicaid is 100 percent funded by the general fund.
The discretionary budget is $1.203 trillion. More than half goes toward military spending, including the and other defense-related departments. The rest must pay for all other domestic programs. The largest are Health and Human Services, Education, and Housing and Urban Development.
There is an emergency fund of $111.4 billion that's not included in the budget process. Most of that ($88.9 billion) goes to Overseas Contingency Operations to pay for wars.
Military spending also includes $181.3 billion for defense-related departments. These include Homeland Security, the State Department, and Veterans Affairs. These departments also receive emergency funding of $18.7 billion. For more on military spending, see War on Terror Costs, War in Iraq Costs and Economic Impact of 9/11.
07How the Deficit Contributes to the National Debt
Each year, the deficit adds to the U.S. debt. This anticipated tax slows economic growth, like driving a car with the brakes on. It raises interest rates, as investors demand more return. They become hesitant to purchase Treasurys, fearing they may not be repaid.
Now that the economy has recovered, deficit spending is not necessary. Congress should create a budget surplus to reduce the national debt burden. They don't because politicians who slice popular programs are usually cut, themselves, in the next election.
Congress created the budget process. First, the Executive Office of Management and Budget prepares the budget. The president submits it to Congress on or before the first Monday in February. Congress is supposed to respond with spending appropriation bills that go to the president by June 30. The president has 10 days to reply.
Most important, the deadline for budget approval is September 30. If it isn't approved, the government can shut down, as it did in January 2018 and in 2013. To avoid that, Congress usually passes a continuing resolution. It keeps the government running at spending levels of the last budget. Since the FY 2010 budget, Congress has only followed the budget process twice.
