Where Do Grants Come From? U.S. Sources Explained

1. Where Grants Come From: The Short Answer

Grants in the United States come from four main sources:

1. Federal government appropriations — funded by federal taxes and administered by federal agencies
2. State and local government revenues — funded by state taxes, local property taxes, and sometimes specialized revenue streams like lottery proceeds
3. Private foundation endowments — funded by past donations from individuals, families, or corporations, invested to generate ongoing grantmaking capacity
4. Corporate giving programs — funded directly from corporate revenues as part of corporate philanthropy or community relations

A smaller share of grant funding also comes from tribal governments, international organizations, and specialized funders like legal settlement funds or professional associations. Together, these sources distribute over $1 trillion in grant funding each year across every domain — health, education, community development, research, arts, environment, workforce, and dozens more.

Understanding where grant money actually comes from is essential to knowing what's available and how to pursue it. This guide walks through each funding source in detail. For the broader system context, see our complete guide to how grants work in the United States.

2. The Four Sources at a Glance

The chart below shows the relative scale and characteristics of each grant funding source in the U.S.

3. Where Federal Grant Money Comes From

Federal grants are the largest single source of grant funding in the United States by a wide margin. The federal government distributes over $700 billion in grants annually across every domain of public activity.

The path from taxpayer to grant recipient

Federal grant money flows through a well-defined process:

1. Federal taxes are collected by the IRS and Treasury — income taxes, payroll taxes (Social Security and Medicare), corporate taxes, and various excise taxes. When spending exceeds revenue, additional funds come from federal borrowing (Treasury securities)
2. Congress passes annual appropriations bills that allocate funds to federal agencies. Each agency receives budget authority for specific programs, including grant programs
3. Federal agencies design grant programs within their appropriated funds. Programs are established either by underlying statute (Congress explicitly authorizes a program) or by agency discretion within broader statutory authority
4. Agencies publish Notices of Funding Opportunity (NOFOs) on Grants.gov and their own systems. Eligible applicants apply, applications are reviewed, and awards are made
5. Award funds are distributed to recipients over the period of performance

Which federal agencies distribute grants

Nearly every federal agency operates grant programs. The largest grantmaking agencies by dollar volume:

Most federal grant volume goes to states, local governments, and health systems through large formula programs like Medicaid and highway funding. Competitive project grants — the type most nonprofits, small businesses, and researchers apply for — represent a smaller but still substantial share of federal grantmaking.

The distinction between formula and competitive federal grants

Not all federal grant money is competitive. A significant portion flows automatically to eligible recipients through formula grants. For a fuller treatment of grant types, see our guide to types of grants.

4. Where State and Local Grant Money Comes From

State and local governments are the second-largest source of grant funding, distributing over $200 billion in grants annually.

State grant funding sources

State grant money comes from several revenue streams:

State income taxes and sales taxes. In most states, the largest single funding source. States use general fund revenue to fund grant programs administered by state agencies

Federal pass-through funding. Substantial amounts of federal money flow through state agencies to local recipients. When you receive a grant from a state agency that's funded by federal dollars, the money originated federally but you interact with the state as the administering entity. See state vs. federal grants for how this distinction affects applicants

Special revenue sources. Many states have specialized grant funding streams:

• Lottery proceeds (dedicated to education, veterans, senior services in many states)
• Marijuana tax revenue (in states with legal marijuana, often dedicated to specific programs)
• Legal settlement funds (like the opioid settlements funding addiction treatment)
• Gambling revenues (from tribal compacts or state-authorized gambling)
• Environmental fees and fines (funding conservation and remediation)

Bond proceeds. States occasionally issue bonds for major capital programs (education infrastructure, transportation, water) and distribute those funds as grants

Local grant funding sources

County, city, and municipal governments also operate grant programs, though at smaller scale than state programs. Sources include:

Property taxes. The dominant local government revenue source, funding many local grants

Sales taxes and business taxes. In localities that levy them

Federal and state pass-through. A significant share of local government grantmaking is actually redistribution of federal or state funds

Special assessments and impact fees. Sometimes dedicated to specific grant programs (housing trust funds, arts funding)

For applicants who are themselves local governments, see grants for municipal and county governments.

How to know which state and local programs exist

State and local grant discovery is fragmented. Some states aggregate opportunities on central portals; others scatter them across dozens of agency websites. Systematic monitoring of state agency programs relevant to your work is the reliable approach. For coverage of discovery mechanics, see how to search for grants.

5. Where Foundation Grant Money Comes From

Private foundations distribute approximately $105 billion in grants annually — the largest source of grant funding outside of government.

How foundations get their money

Foundation grant money comes from endowments — pools of assets that were originally donated by individuals, families, or corporations. The endowment is invested in stocks, bonds, real estate, and other assets. The investment returns fund the foundation's ongoing grantmaking, allowing the endowment principal to sustain grants indefinitely.

The typical foundation funding model:

1. A wealthy donor (or family, or corporation) contributes assets to establish a foundation. This might be a $10 million family foundation or a $50 billion global foundation
2. The foundation invests the endowment — typically in diversified portfolios managed by professional investment staff or outside advisors
3. Federal tax law requires foundations to distribute at least 5% of their endowment value each year in grants and qualifying charitable expenses. This is called the "payout requirement" and prevents foundations from perpetually accumulating wealth without distributing it
4. Grants are made according to the foundation's mission, priorities, and board discretion

The scale of the U.S. foundation sector

The U.S. has over 90,000 active private foundations. The largest concentrate significant wealth:

But most foundations are much smaller. The typical U.S. foundation has an endowment under $10 million and makes grants totaling $500,000 or less annually. Community foundations, family foundations, and corporate foundations each play distinct roles in the ecosystem.

Types of foundations

Foundations differ in structure and source of funds:

Private independent foundations. Established by wealthy individuals or families, with independent boards. Most large national foundations (Ford, MacArthur, Robert Wood Johnson) are this type

Family foundations. Private foundations with family members serving as board and staff. Priorities often reflect family interests and values

Corporate foundations. Established by corporations, typically funded through periodic contributions from the corporation. Corporate foundations often align grantmaking with corporate values or geographic footprint

Community foundations. Public foundations that hold pooled charitable funds from many donors. Focus grantmaking within a defined geographic area. Silicon Valley Community Foundation is the largest by assets; there are approximately 900 community foundations across the U.S.

Operating foundations. Foundations that primarily run their own programs (like the Getty Trust operating museums) rather than making grants to others. Represent a small share of the foundation sector

6. Where Corporate Grant Money Comes From

Corporate giving programs distribute approximately $30 billion in grants annually. Corporate grant money comes from three distinct channels, each with different characteristics:

Direct corporate philanthropy

Many corporations run direct giving programs funded from corporate revenues. A retail chain might allocate a percentage of profits to community grants. A bank might fund financial literacy programs. Tech companies frequently fund STEM education initiatives.

These programs are typically administered by corporate community relations or corporate social responsibility (CSR) departments. Grants often prioritize:

• Communities where the company operates
• Causes aligned with corporate values or brand positioning
• Employee volunteer preferences (via matching gift programs)
• Industry-adjacent causes (banks fund financial literacy, hospitals fund community health)

Corporate foundations

Larger corporations often establish corporate foundations to formalize grantmaking. The corporation contributes funds to the foundation, which then makes grants. This structure separates the corporation's core business from its charitable activity for legal and tax purposes. The Coca-Cola Foundation, Bank of America Charitable Foundation, and Walmart Foundation are prominent examples.

Sponsorships and cause marketing

Some corporate funding isn't technically grantmaking but functions similarly. Sponsorships of nonprofit events, cause-marketing partnerships, and product donations all channel corporate resources to nonprofit recipients. These arrangements typically involve marketing considerations alongside charitable intent.

Why corporate grants work differently than foundation grants

Corporate grants share characteristics with foundation grants (private funding, no reimbursement mechanism, program officer relationships), but differ in important ways:

• Corporate priorities can shift more quickly with business conditions than foundation priorities
• Corporate grants often expect brand visibility or marketing value
• Employee engagement (volunteer opportunities, employee giving matches) is often part of the value exchange
• Corporate grantmaking budgets rise and fall with corporate profitability

7. Where Tribal Grant Money Comes From

Tribal governments in the U.S. are sovereign nations with their own funding sources for grantmaking. Tribal grants come from several distinct streams:

Federal appropriations to tribes. The federal government has specific trust obligations to tribes, funded through the Bureau of Indian Affairs, Indian Health Service, and other federal programs. Some of this funding flows to tribes as pass-through funding that tribes then re-grant

Gaming revenues. For tribes operating casinos or other gaming facilities, gaming revenues fund significant grantmaking. Some tribes use gaming revenues to fund community programs, education, health, and infrastructure — both for tribal citizens and, in some cases, for the broader regional community

Tribal enterprises. Revenues from tribal businesses (energy, tourism, cannabis, retail) sometimes fund grantmaking

Tribal budget appropriations. Similar to states, tribal governments allocate general fund revenue to grant programs administered by tribal agencies

Access to tribal grants is typically restricted to tribal citizens, tribal organizations, or entities working within tribal jurisdictions. Specific eligibility varies significantly by tribe.

8. Other Grant Funding Sources

Beyond the four main sources, several smaller streams contribute to the U.S. grant ecosystem:

International and multilateral organizations. Organizations like the United Nations, World Bank, and international development agencies operate grantmaking programs. U.S.-based nonprofits sometimes access this funding for global programs

Professional associations and trade groups. Professional associations sometimes operate small grant programs supporting research, education, or community initiatives in their fields

Legal settlements. Class action settlements, particularly against tobacco, opioid, and financial industries, have created significant grant funding pools distributed to state and local recipients for related purposes

Endowed universities and academic centers. University-affiliated centers sometimes distribute research grants funded by university endowments, particularly for collaborative research with external organizations

Faith-based grantmaking. Religious denominations and faith-based foundations distribute grants supporting religious institutions, faith-aligned services, and community programs

Individual major donors. Extremely wealthy individuals sometimes make direct grants outside foundation structures, though this is uncommon compared to foundation-mediated giving

Together, these smaller sources represent perhaps $50-100 billion in additional annual grant activity, though precise figures are difficult to compile.

9. Who Receives All This Grant Money?

Understanding where grants come from also requires understanding where they go. The largest recipient categories:

State and local governments receive the biggest share of federal grant dollars — most of the $700B in federal grants flows to states and localities through formula programs like Medicaid, highway funding, and education programs

Healthcare systems and providers receive substantial federal funding through Medicare, Medicaid, and research grants

Nonprofit organizations receive both government and foundation funding across every mission area. See grants for nonprofits for the nonprofit-specific view

Educational institutions — K-12 schools, colleges, and universities — receive large formula grants (Title I, research funding) and competitive grants

Small businesses and researchers receive federal research grants (SBIR, STTR, NIH research) and specific-purpose funding. See federal grants for small businesses

Individuals rarely receive grants directly. Federal financial aid for education and some specialized programs are exceptions. Most grantmaking flows to organizations, not individuals

10. What This Means for Grant Strategy

Understanding grant funding sources isn't just background — it directly shapes how organizations should approach grant pursuit:

Match your work to funders whose money actually flows there. Federal money flows to specific priorities determined by Congress and agency mission. Foundation money flows to priorities determined by trustees. State money flows to priorities determined by state legislatures. Understanding the funding source helps predict which funders will prioritize your work

Diversify across funding sources. Organizations dependent on a single funding source face significant risk. A federal budget change, a foundation strategy shift, or a corporate priority change can dramatically affect funding availability. Balanced portfolios spanning federal, state, foundation, and earned revenue are more resilient

Follow the money at the source. When federal appropriations shift (like the recent Infrastructure Investment and Jobs Act, CHIPS and Science Act, or Inflation Reduction Act), significant new grant funding flows to specific priorities. Organizations aligned with those priorities benefit; others face static or shrinking opportunities

Understand the multi-year timing. Federal budgets, foundation strategies, and state appropriations all operate on different timelines. Grant strategy needs to anticipate funding availability 12-36 months out, not just this fiscal year

For strategic frameworks that put this into practice, see how to build a grant pipeline.
