The federal government of the United States’ expenditures and receipts are included in the national budget.

The budget is the financial depiction of the government’s priorities, reflecting previous arguments and opposing economic theories. Government spending is mostly allocated to healthcare, retirement, and defence initiatives. The nonpartisan Congressional Budget Office conducts in-depth research on the budget and its financial implications. It has been predicted that significant budget deficits during the ensuing 30 years are expected to raise the public’s share of the government debt to previously unheard-of levels—from 98 percent of GDP in 2020 to 195 percent in 2050.


The budget document frequently starts with the President’s recommendation to Congress for funding levels for the following fiscal year, which starts on October 1 and ends on September 30 of the year after. The year it finishes is referred to as the fiscal year. But according to the legislation, Congress is the entity that must approve appropriations each year and send financing bills that have been approved by both chambers to the President for signature. Rules and laws governing the federal budget process apply to congressional choices. The House and Senate committees, as well as the Appropriations subcommittees, are given spending caps by budget committees. These committees then pass separate appropriations bills to distribute cash to various government programmes.

As “stop gap” measures, numerous appropriations bills must be issued if Congress is unable to pass an annual budget. An appropriations bill that has been approved by Congress is then forwarded to the president, who has the option of signing it into law or vetoing it. A bill that has been vetoed is sent back to Congress, where it can be passed into law with a two-thirds majority in each chamber. A single omnibus reconciliation bill may also be created by Congress by combining some or all appropriations bills. Additionally, the president may ask for and the Congress may approve emergency or supplemental appropriations legislation.

Several governmental organisations offer budget information and analysis. These include the Treasury Department, the Office of Management and Budget (OMB), the Congressional Budget Office (CBO), and the Government Accountability Office (GAO). The ageing population, growing interest costs, and spending for healthcare programmes like Medicare and Medicaid have all been cited by these organisations as major long-term fiscal challenges for the federal government.

The budget deficit increased by $205 billion (26%), or from $779 billion in FY2018 to $984 billion in FY2019. The budget deficit climbed by $113 billion, or 17.0%, from $666 billion in FY2017 to $779 billion in FY2018. An anticipated 4.7% GDP was the deficit in 2019, up from 3.9% GDP in 2018 and 3.5% GDP in 2017. The deficit has historically been 2.9% of GDP. The CBO predicted that the FY2019 budget deficit would be $610 billion if the laws in existence at the time stayed in place in January 2017, soon before President Trump’s inauguration.

In comparison to the prediction, the $984 billion actual results show a $374 billion or 61% increase, primarily due to tax cuts and increased spending. In a similar vein, the FY 2018 budget deficit, which came in at $779 billion, exceeded expectations by $292 billion, or 60%.

Budget Principles:

No money may be taken from the Treasury except in accordance with appropriations granted by law, and a regular Statement and Account of Receipts and Expenditures of All Public Money shall be published from time to time, according to the U.S. Constitution’s Article I, section 9, clause 7.

The Budget and Accounting Act of 1921 mandates that the President of the United States submit a budget request to Congress each year for the upcoming fiscal year. The president must provide a budget by the first Monday in January or the first Monday in February, according to current law. Budgets are typically submitted by presidents on the first Monday in February. However, in some new presidents’ first year when the outgoing president belonged to a different party, the budget submission was postponed.

Additional “special” or “emergency” funds may be passed by Congress. Certain Congressional budget enforcement regulations do not apply to spending that is classified as a “emergency.” Occasionally, extra appropriations have been used to pay for disaster relief, as was the case following Hurricane Katrina. Other times, money from emergency supplemental appropriations acts is used to assist projects that aren’t directly tied to crises, like the 2000 Census of Population and Housing. Most of the expenses associated with the war and occupation in Iraq and Afghanistan up to this point have been covered by special appropriations.

The funding levels in the president’s budget will typically differ from those in budget resolutions and appropriations bills, which reflect the spending objectives of Congress. But when the president’s party holds a majority in Congress, the president retains significant control over the budgeting process thanks to his or her veto power and legislative allies.

Budgetary power versus expenditures:

Because the government might incur liabilities for future years, the budget authority and outlays for a fiscal year typically vary. This means that, in many instances, budget authorization from a prior fiscal year may be used to the expenditure of funds in subsequent fiscal years, such as in the case of a multi-year contract.

The legal power granted by federal law to enter into financial commitments that may lead to current or future outlays involving federal government monies is known as budget authority. Outlays, which are typically synonymous with “expenditure” or “spending,” refer to the issuance of checks, disbursement of cash, or electronic transfer of monies made to liquidate a federal obligation. Appropriations are the budgetary power to take on debt and withdraw money from the Treasury for specific uses. A few housing and military initiatives have multi-year appropriations, which outline their spending authority for a number of upcoming fiscal years.

In the congressional budgeting process, a “authorization” (officially the “authorization act”) gives the executive branch the legal right to act, creates an account that can accept funding to carry out the action, and places a cap on the amount that can be spent. But unless Congress authorises a “appropriation,” which calls on the U.S. Treasury to disburse funds, this account stays empty (up to the limit provided for in the authorization). The amount of funding authorised by Congress does not have to be appropriated in full.

In the same bill, Congress may both authorise and appropriate. Such legislation, also referred to as “authorization bills,” typically includes a multi-year authorization and appropriation. Authorization bills are particularly helpful for supporting entitlement programmes, which are benefits that, according to federal law, every person is entitled to regardless of whether any money is appropriated. Authorization legislation are helpful for granting a government agency the authority to negotiate contracts, borrow money, or guarantee loans. Two-thirds of all federal expenditure in 2007 was authorised by legislation.

Federal Budget Data:

Budget information is provided by numerous government agencies. These include the U.S. Treasury Department, the Office of Management and Budget (OMB), the Congressional Budget Office (CBO), and the Government Accountability Office (GAO). The Budget and Economic Outlook, which the CBO releases in January and usually updates in August, spans a ten-year time frame. In addition, a Monthly Budget Review and Long-Term Budget Outlook are published in July. A budget update is normally released by the OMB in July. The OMB is in charge of organising the President’s budget, which is submitted in February.

Financial Statements of the United States Government are published by the GAO and the Treasury typically in December after the end of the federal fiscal year, which ends on September 30. A concise overview, the Citizen’s Guide, is available. The Combined Statement of Receipts, Outlays, and Balances, which offers comprehensive information on federal financial activity, is another document the Treasury Department produces each December for the previous fiscal year.

Federal Budget Projections:

In its yearly “Long-term Budget Outlook,” the Congressional Budget Office (CBO) forecasts budget information such revenues, expenses, deficits, and debt. The outlook for 2018 contained estimates for debt up to and including 2048. The CBO provided a number of scenarios with various possible outcomes.

As the population ages and healthcare expenditures increase more quickly than the rate of GDP growth, both the “Extended Baseline” scenario and the “Extended Alternative Fiscal” scenario produce much greater debt levels relative to the size of the economy (GDP). The CBO also created scenarios that involve severe austerity measures and that, over time, maintain or lower debt relative to GDP. The extent of the adjustments that would be required to reach a particular federal debt objective was calculated by CBO. For instance, if lawmakers decided to cut non-interest spending, raise revenues, or combine both strategies to make changes that totaled 3.0 percent of GDP each year starting in 2019, they might lower the debt to 41 percent of GDP in 2048 (the average over the preceding 50 years).

Tax Descriptions:

The federal personal income tax is progressive, which means that higher income levels are subject to a higher marginal tax rate. For instance, the tax rate for a married couple filing jointly in 2010 was 10% for the first $17,000 of taxable income and 35% for earnings over $379,150. Since 1980, the top marginal tax rate has significantly decreased. As an illustration, the top tax rate was reduced from 70% to 50% in 1980 and to 28% in 1988. The highest rate was reduced from 39.6% to 35% by President Obama’s 2010 extension of the Bush tax cuts from 2001 and 2003. The income tax rates for individuals making over $400,000 and couples making over $450,000 were increased by the American Taxpayer Relief Act of 2012. Numerous exemptions and deductions mean that, on average, 35 to 40% of American households pay no federal income tax. In 2009, compared to 38% in 2007, this climbed to 51% due to the recession and tax cut stimulus initiatives. 46% of households in 2011 paid no federal income tax, whereas the richest 1% were responsible for nearly 25% of all taxes collected. Including payroll taxes, the top 1% paid almost 46% of the federal income taxes in 2014. 

Tax Expenditures:

In the context of the individual, payroll, and corporate income tax systems, “tax expenditures” relate to income exclusions, deductions, preferential rates, and credits that lower revenues for any given level of tax rates. They contribute to the deficit in the government budget, just like regular spending does. They have an impact on how people choose to work, save, and invest, as well as how money is distributed. The CBO estimates the amount of lost federal revenues at close to 8% of GDP, or around $1.5 trillion in 2017, which is roughly half the amount of money the government normally receives in income and almost three times the size of the budget deficit. The amount of additional revenue that would be collected is somewhat less than the predicted magnitude of the tax expenditure since reducing a tax expenditure alters economic behaviour. 

Spending restrictions and social safety nets:

Spending on Social Security, Medicare, and Medicaid is seen as required spending because these programmes are supported by longer-term Congressional appropriations. People who meet the necessary criteria for benefits are legally entitled to them; as a result, Social Security and Medicare are commonly referred to as “entitlements.” The majority of participants pay taxes into both systems during the course of their working lifetimes. Programs like Food Stamps are examples of appropriated entitlements. Some obligatory expenses, like the salary of members of Congress, are not a part of any entitlement programme. Net of receipts that partially fund the programmes, mandatory spending made up 59.8% of all government expenditures, and net interest payments made up the remaining 6.5%. These percentages were correspondingly 53.2% and 12.5% in 2000.


In 1965, Medicare was created, and it has since grown. Medicare expenditures increased by $58 billion or 9% in 2016 to $692 billion from $634 billion in 2014. Estimated coverage for the programme in 2013 was 52.3 million people. There are four separate components, each of which is funded differently: Supplementary Medical Insurance is paid for by beneficiary premiums (set at 25% of the estimated programme costs for the elderly) and general revenues (the remaining amount, roughly 75%), with Hospital Insurance being primarily funded by a dedicated payroll tax of 2.9% of earnings, split equally between employers and employees. Medicare Advantage is a private plan option for beneficiaries that is paid for by the Hospital Insurance and Supplementary Medical Insurance trust funds. Part D prescription drug coverage is paid for by beneficiary premiums (roughly 25%) and general revenues (roughly 75%), and is covered by the Supplementary Medical Insurance trust fund.

Social Security:

In regard to its three components, Social Security is formally known as “Old-Age, Survivors, and Disability Insurance” (OASDI). It is principally supported by a 12.4% dedicated payroll tax. Payouts of benefits totaled $910 billion in 2016 compared to $882 billion in 2015, a $28 billion or 3% increase. Since 2010, Social Security’s overall expenses have surpassed its non-interest income. In 2010, 2011, and 2012, the non-interest income gap between costs and revenues was around $49 billion, $45 billion, and $55 billion, respectively. An estimated 157 million people contributed to the programme in 2010, and 54 million people got benefits, or 2.91 workers for every recipient.

Examples include lowering the recipients’ future annual cost-of-living-adjustments (COLA), extending the retirement age, and increasing the income threshold that triggers payroll taxes ($118,500 in 2014). [45] [46] The Social Security system has the legal right to compel the government to borrow money in order to pay all promised benefits through 2036, when the Social Security Trust Fund is anticipated to run out, due to the mandatory nature of the programme and significant accumulated surplus in the Social Security Trust Fund. After that, the programme will pay roughly 75-78% of the guaranteed payments for the rest of the century under the existing law.

Interest Expense:

According to CBO, net interest on the public debt increased by $17 billion or 8% from FY2015 to FY2016, totaling about $240 billion (6% of spending). Interest rates increased in direct proportion to debt levels. [5] The GAO reported a number of $245 billion for FY2012, a decrease from $251 billion. On a total interest expense of $432 billion, the government also incurred a non-cash interest charge of $187 billion for intragovernmental debt, mostly the Social Security Trust Fund.  The national debt increased in FY2012, although the interest rate paid decreased, according to GAO. The cost of interest would rise sharply if interest rates reached their historical averages. By January 2012, the amount of public debt held by foreigners had risen to $5.0 trillion, or around 50% of the total. In contrast to previous years, when interest was paid to Americans who held the national debt, presently approximately 50% of interest payments are leaving the nation. As the U.S. debt rises and interest rates move from historically low levels to more usual levels, interest costs are expected to increase considerably.

Trump Tax Cuts:

In December 2017, President Trump authorised the Tax Cuts and Jobs Act. According to the CBO, the 2017 Tax Act will result in a $2.289 trillion rise in total budget deficits (debt) over the ten-year period of 2018–2027, or $1.891 trillion after accounting for macroeconomic feedback. This is in addition to the existing $20 trillion national debt as well as the $10.1 trillion rise projected under the June 2017 policy baseline. According to a CBO assessment from December 21, 2017, the Tax Act will slash spending for lower-income households while lowering taxes for higher-income households: Overall, the shift in net federal revenue and spending has the effect of increasing deficits (mainly due to tax cuts) allotted to higher-income tax filing units while decreasing deficits (largely due to spending reductions) assigned to lower-income tax filing units.

In August 2019, The New York Times published the following: “After Mr. Trump’s 2017 tax cuts, which lowered individual and corporate tax rates, there was a sharp decline in federal revenue, which led to significantly less money flowing to the Treasury Department. This is what is to blame for the growing levels of red ink. Before the tax plan was adopted in December of that year, in June 2017, the budget office anticipated that tax revenues for 2018 and 2019 would be more than $430 billion short.” 

Healthcare Reform:

Since 2010, the CBO has repeatedly stated that the Patient Protection and Affordable Care Act, often known as “Obamacare,” will decrease the deficit because its tax hikes and future Medicare spending reductions would more than offset its additional spending for low-income household subsidies. According to a CBO analysis from June 2015, depending on the influence of macroeconomic feedback effects, repealing the ACA would result in an overall deficit increase of between $137 billion and $353 billion from 2016 to 2025. In other words, the ACA lowers the deficit because repealing it would increase it.  Higher administrative costs of a private system with multiple payment methods; higher prices for identical goods and services; more expensive volume/mix of services with higher usage of more expensive specialists; aggressive treatment of very ill elderly patients rather than palliative care; less use of government pricing intervention; and higher income levels driving greater demand for healthcare. [84][85][86] The primary driver of health insurance prices is healthcare, which makes it difficult for millions of families to afford coverage. It is still up for debate whether to whether the Republican alternatives (AHCA and BCRA) and the present law (ACA/Obamacare) go far enough in addressing the cost issue.
