Ever wonder where federal tax dollars go? Curious how much federal spending goes toward the military, health care, or education? Want to understand what all those government programs you hear about do? If so, FedGovSpend™ Explorer is the app for you! Using data from the Office of Management and Budget (OMB) and Congressional Budget Office (CBO), FedGovSpend™ Explorer shows, in easy-to-follow government spending pie charts, the budget outlays of the United States federal government. Easy to understand explanations are available at a touch of the screen.

FedGovSpend™ Explorer is available for download from the Apple and Google Play stores.

When you first open the app you’ll see the big, broad, purposes to which federal spending goes: Health, National Defense, Transportation, and the rest. If you want to dig deeper into a specific area you can. Tap on “Health,” for example, and see federal spending broken down more narrowly by health care services, health research, occupational safety, and more. Tap on one of those categories and get even more detail. At each layer, descriptions are available for what those spending dollars accomplish. You can explore how much goes to Medicaid, government retiree health coverage, the National Institutes of Health, and the other federal programs that comprise the government’s health spending. The answers are here in as much or as little detail as you want.

Years, Data Sources, and Updates

FedGovSpend™ Explorer currently shows US government spending in outlays for Fiscal Years 2019 and 2020, projected outlays for Fiscal Year (FY) 2021, and outlays that reflect the president's budget proposal for FY 2022. The federal government’s fiscal year runs from October through September. For examplee, FY21 runs from October 1, 2020 to September 30, 2021. FY 2021 will be updated as newer projections become available. FY 2022 will be updated when projections become available after congressional action. These data are from the Office of Management and Budget's (OMB) Public Budget Database and the Congressional Budget Office's (CBO) Budget and Economic Data site.

As new data become available, FedGovSpend™ Explorer will be updated to reflect the most up to date projections and actual spending data in past and current fiscal years. Prior year outlay data typically become available when the president’s budget proposal is released early in the calendar year, except in years following presidential elections, when the release is typically delayed by several months.

How Spending Is Measured: Outlays Versus Budget Authority

There are multiple ways to measure federal spending. FedGovSpend™ shows “outlays,” which are a measure of how much money the federal government spends in a given fiscal year. This differs from “budget authority,” which is also used by some analysts. Budget authority is how much money has been authorized in a fiscal year—even if those dollars are not spent until later years.

Organization by Purpose

FedGovSpend™ allows users to visualize what the federal government is spending money on, relying on the federal government’s official budget functional classifications. Outlays are organized in a hierarchy from very broad categories of spending to more specific. The budget terms used for these levels of aggregation are “function,” “subfunction,” “bureau,” and “account.” There are 17 "national needs" budget function categories at the top level, which are then divided into subfunction and further divided into bureau and then account level categories of spending. For example, the National Defense function is comprised of three subfunctional categories: Military Outlays of the Department of Defense, Defense-Related Activities, and Atomic Energy Defense Activities. These subfunctions are then split into “bureau” level categories such as “Operation and Maintenance” and “Military Personnel.” Although the government uses the word “bureau” in its data sets, these categories do not always indicate a specific office or unit in the government and the term is not generally used in FedGovSpend™. There is a final “account” level of specificity below the bureau level which describes specific line-item accounting of spending. FedGovSpend™ does not show account level spending but instead uses information from these account-level data to generate the bureau-level descriptions. More details about the federal government’s system of budget classification and its functional and subfunctional categories can be found in the US Government Accountability Office’s publication “A Glossary of Terms Used in the Federal Budget Process”.

Some bureau-level spending appears in multiple subfunctions and functions. For example, The Administration for Children and Families has outlays classified under both the “Income Security” function, in the “Other Income Security” subfunction, and the “Education, Training, Employment, and Social Services” function, in the “Social Services” subfunction. Where appropriate, bureau descriptions denote where spending occurs across multiple functional or subfunctional categories to give a more complete picture of how that agency or program fits into overall federal spending.

Organization by Mandatory versus Discretionary Spending

The app also allows users to view spending across budget function classifications separately for the mandatory and discretionary parts of the federal budget. Mandatory spending refers to spending that is permanently authorized (such as Social Security), while discretionary spending must be approved each year by Congress and the President through the annual federal budget process and related appropriations bills. To toggle between views, click the menu button in the upper right-hand corner of the screen and select your preferred view using the buttons under “Data Organization Choice”.

For clarity and ease of understanding FedGovSpend™ Explorer does not strictly follow the official government organization in every case, although in general it does and the data are all sourced from official sources.

A Note on Tax Expenditures

Some government spending is administered through the tax code. The simplest way to think about this is that instead of the government sending a check, as it does for Social Security and other benefit spending, a “tax expenditure” reduces the beneficiary’s federal tax liability. Whether one gets a check for $1,000 from the government or pays $1,000 less in taxes amounts to the same thing financially. There are lots of examples of these tax expenditures across government spending, including the Earned Income Credit, the Child Credit, Health Care Subsidies, the Mortgage Interest Deduction, Tax Exempt Interest, and numerous business tax breaks. How these are handled in government accounting is a little tricky. In general, to the extent that tax expenditures reduce the amount of tax paid, they show up in the revenue side of the budget as lower tax collections—and thus do not appear in FedGovSpend™ Explorer. There is an exception to this rule, however. For some tax credits, if the credit exceeds the tax that would otherwise be owed, the government does send a check (or transfers funds) like any other spending program for the amount by which the credit exceeds the pre-credit tax liability. The amounts sent in these “refundable tax credits” do appear in federal budget outlays as spending and are therefore included in FedGovSpend™ Explorer.

One question you might have is “if tax expenditures are just government spending in another form why aren’t they all included in FedGovSpend™ Explorer?” Although the federal government does produce a “tax expenditure budget”, the challenge with integrating it with the rest of the spending budget is that the complexity of the tax code creates many interactions between different tax expenditures. In the regular spending side of the budget if the government spends less or more money on a program the impact is usually straightforward. Decreasing or increasing the size of some tax expenditures, however, can cause ripple effects on the rest of the tax return, which can increase or decrease the spending on other tax expenditures. Without being able to account for those interactions, mixing in the entire set of tax expenditures with the rest of the budget would be misleading.

Credit Subsidy Accounting

Government credit subsidy programs can be either subject to “credit reform” accounting, in which case the subsidy cost is calculated and is included in spending, or accounted for on the basis of cash flow. Descriptions of credit programs in FedGovSpend™ Explorer specify which form of accounting is used.

Additional Federal Budget Resources

The Center on Budget Policy and Priorities (CBPP) provides nonpartisan research and analysis of the federal budget, with an emphasis on how budget policy impacts low-income Americans. Some helpful CBPP introductory primers to the federal budget process include:

USAspending.gov’s Spending Explorer is a web-based tool that allows users to explore federal spending by linking federal agency financial data together in one database. It was created as part of 2006’s Federal Funding Accountability and Transparency Act, and expanded in 2014 after the passage of the Digital Accountability and Transparency Act. USAspending.gov’s data comes directly from federal agency financial systems, other government systems, and entities that receive government awards. These data are very similar to the data reported in the FedGovSpend™ Explorer app across functional, subfunctional, and bureau level spending categories, although USAspending.gov’s data show budget obligation rather than outlays. Budget obligation differs from outlays in that obligation refers to money the government has promised to spend either immediately or in the future, while outlays are actual spending amounts. In addition, USAspending does not have descriptions of the spending.
