You can find out who funds a nonprofit by checking Form 990 filings, state charity registrations, annual reports, and the organization’s website. Nonprofits receiving over $50,000 in gross revenue must file Form 990 with the IRS, which lists major donors and funding sources. Federal law requires this transparency so donors, regulators, and the public can see where nonprofit money comes from and how it gets spent.
According to recent data, over 1.5 million nonprofits operate in the United States, yet many donors and watchdog groups struggle to find funding information. This transparency gap creates trust problems and makes it hard for donors to research organizations before giving money. Understanding how to access nonprofit funding data helps you evaluate whether an organization deserves your support.

How Nonprofits Must Disclose Their Funding
Nonprofits file different forms based on their size and structure. The IRS requires nonprofits with gross receipts over $50,000 to file Form 990-N, 990-EZ, or 990, depending on their total revenue. Smaller nonprofits with less than $50,000 in annual revenue may not have to file with the IRS, but most states still require them to register as charities.
Form 990 is the most detailed filing and includes a section listing the organization’s largest donors who gave $5,000 or more. However, there’s an important catch: nonprofits can keep donor names private if the donation came with a restriction that it stay anonymous. This means not all donors appear on these forms, even if they gave large amounts of money.
State governments also require nonprofits to register as charities and file annual reports. Each state has its own rules about what funding information nonprofits must disclose. Some states require charities to list all donors above a certain amount, while other states only ask for the total revenue without naming specific donors.
The Federal Requirement for Transparency
Federal tax law governing nonprofits requires financial transparency as the price of tax-exempt status. When a nonprofit gets tax-exempt status, it must operate for a charitable, educational, religious, scientific, or social purpose. In exchange for not paying taxes, these organizations must operate with public transparency about their finances and funding sources.
The IRS created Form 990 specifically so the public can see how nonprofits use donations and what funding sources they rely on. This form must be made available to anyone who requests it, either directly from the nonprofit or through free IRS databases. The consequence of not filing required forms is serious: nonprofits can lose their tax-exempt status and face penalties and back taxes.
Most nonprofits must make their most recent three years of Form 990 filings available to the public upon request. If a nonprofit refuses to share this information, that’s a major red flag about their transparency. Many state attorneys general have enforcement power to require nonprofits to disclose their funding and file required documents.
Finding Funding Information: Step by Step
Start with the nonprofit’s own website. Many organizations publish annual reports that explain their funding sources, donor recognition lists, and financial summaries. These reports often highlight major donors and funding priorities in an easy-to-read format. However, not all nonprofits publish this information, so the website is just your first stop.
Check the IRS tax-exempt organization search. The IRS maintains a database where you can search for any nonprofit by name or Employer Identification Number (EIN). Once you find the organization, you can download recent Form 990 filings. These forms include detailed financial information, including a summary of where money came from and where it went.
Use free nonprofit research websites. Sites like GuideStar and ProPublica Nonprofit Explorer let you search for any registered nonprofit and view their Form 990 data. These websites organize the information in a user-friendly way so you don’t have to read the entire IRS form yourself. Many people find these sites easier to use than the IRS database.
Search state charity registrations. Every state has a charity registration office, typically in the Attorney General’s office or state charities division. You can search state databases to find nonprofits registered to fundraise in your state. State filings sometimes require different funding disclosures than federal filings, so checking both sources gives you a complete picture.
Request Form 990 directly from the nonprofit. If you can’t find the form online, you have a legal right to request it from the nonprofit’s offices. The IRS requires nonprofits to provide copies of Form 990 within 30 days of your request, though they can charge a small fee for copying and shipping. If a nonprofit refuses or delays providing this form, you can file a complaint with the IRS.
Three Real-World Funding Scenarios
Scenario 1: The Well-Funded National Charity
A large national nonprofit like the American Red Cross receives funding from multiple sources: individual donations, government grants, corporate sponsorships, and foundation funding. When you look at their Form 990, you’ll see hundreds of thousands of dollars from each category. The form shows that they raised money from disaster relief donations, corporate partners like Walmart and Target, and federal government contracts for blood services.
| Funding Source | Where to Find It |
|---|---|
| Individual donors ($5,000+) | Schedule B of Form 990 |
| Government contracts | Part VII and Schedule A |
| Foundation grants | Narrative section |
| Corporate sponsorships | Annual report and Form 990 |
This organization’s Form 990 reveals that they received millions in government funding for disaster response and blood services. Understanding this funding mix helps donors see whether the organization relies too heavily on one source or maintains a diverse funding base. A nonprofit that depends on government funding might face budget cuts if government priorities change.
The American Red Cross also receives in-kind donations of blood from volunteers, which doesn’t show up as direct monetary funding on Form 990. This is an important distinction because the organization’s actual resources far exceed their cash revenue. When researching any national nonprofit, always ask whether they receive substantial in-kind donations that might not appear in financial statements.
Scenario 2: The Community Foundation Supported by Local Donors
A smaller local food bank might get most of its money from individual donations, grants from community foundations, and in-kind donations of food from grocery stores. When you search for this nonprofit’s Form 990, you’ll see different funding patterns than the national charity. Their funding might show that 60% comes from individual donors, 30% from foundation grants, and 10% from government food programs.
| Funding Pattern | Annual Impact |
|---|---|
| Individual donations under $5,000 | Reported as lump sum total |
| Community foundation grants | Listed as major revenue source |
| In-kind food donations | May not appear in financial |
| Special event fundraising | Shown separately on Form 990 |
This organization’s Form 990 won’t list the names of individual donors who gave under $5,000, but it will show total revenue from that source. The form will specifically name foundation funders because grants typically come in larger amounts. If you want to know about smaller donors, you might need to ask the nonprofit directly or look at their annual report.
Community foundations themselves publish annual reports showing which organizations they funded that year. If you’re trying to understand why a small nonprofit received a specific grant, researching the community foundation’s goals and priorities helps explain the funding decision. This type of research shows how funding often comes through intermediary organizations rather than directly from wealthy individuals.
Scenario 3: The Controversial Nonprofit with Hidden Funding
Suppose a nonprofit focused on political advocacy raises millions but its funding sources are hard to trace. This nonprofit might receive dark money through donor-advised funds or by accepting donations from other nonprofits. When you examine their Form 990, you see large funding from a few entities, but tracing where that money originally came from requires additional research.
| Funding Claim | How to Verify It |
|---|---|
| Grassroots support claim | Check Form 990 donor count |
| Foundation is major funder | Research foundation’s own Form 990 |
| No corporate influence claim | Search corporate donation lists |
| Transparent about sources claim | Compare claims to actual Form 990 |
This scenario shows why deeper research matters beyond just reading Form 990. You might need to check the IRS database for the foundations funding this nonprofit and look at their filings to see where they got their money. News articles and nonprofit watchdog sites sometimes investigate funding patterns that Form 990 doesn’t reveal directly.
Political nonprofits face additional scrutiny because they can accept unlimited donations while maintaining donor anonymity under certain conditions. A 527 political nonprofit or 501(c)(4) social welfare organization can shield donor names in ways that 501(c)(3) charities cannot. When researching politically active nonprofits, understand that the funding disclosure rules differ significantly from charitable organizations.
Where to Find Specific Funding Information
Form 990 contains specific sections where nonprofits disclose funding sources with particular details. Schedule A shows support from government sources, membership dues, and public contributions broken down by category. Schedule B lists the names and addresses of donors who gave $5,000 or more (though some donors can request anonymity). Part VII includes information about officers, directors, and key employees, which sometimes reveals funding relationships and potential conflicts of interest.
The nonprofit section of Form 990 also includes revenue breakdowns that show the percentage of money from each source. Organizations must report whether they received revenue from program services, government grants, membership dues, investment income, or special fundraising events. This breakdown helps you understand the organization’s revenue diversity and whether they depend too heavily on one funding source.
Understanding the specific line items on Form 990 requires some effort, but the Form 990 instructions explain what each section means and what nonprofits must report. If you’re confused by the numbers or format, these instructions help you understand what you’re looking at. The IRS also provides free training for people who want to learn more about nonprofit finances.
Annual reports often provide clearer funding breakdowns than Form 990 and present information in graphics and plain language. Many nonprofits publish pie charts or graphs showing what percentage of funding comes from each source. These reports might also explain why the organization pursued specific funding sources or mention plans to diversify their revenue streams in the future.
Some nonprofits maintain donation pages on their websites listing major donors or grants received. This information supplements what appears on Form 990 and sometimes includes donors who gave just under the $5,000 threshold. However, not all nonprofits maintain these pages, so their absence doesn’t necessarily mean funding is hidden.
Advanced Research: Finding Hidden Funding Patterns
Sometimes the most important funding information requires deeper investigation beyond Form 990. You can research board members and key staff to see if they have connections to major donors or corporations. If a nonprofit’s leader previously worked at a corporation that now donates to the organization, that relationship might explain part of their funding.
Business databases and LinkedIn allow you to trace professional relationships and potential conflicts of interest. A board member who works at a company that donates millions to the nonprofit raises questions about donor influence over organizational decisions. These connections aren’t necessarily illegal, but they reveal funding relationships that might not be apparent from Form 990 alone.
Tracking fiscal sponsors reveals another funding path nonprofits use to receive donations. A fiscal sponsor is an established nonprofit that accepts donations on behalf of a smaller nonprofit that isn’t yet registered or wants to accept grants. If you find donations going to a fiscal sponsor organization, dig deeper to see which projects they support. This is common for startup nonprofits and activist groups that don’t yet have their own tax-exempt status.
Donor-advised funds allow wealthy individuals to contribute money to a fund and then recommend grants over time. When you see a nonprofit funded by a donor-advised fund, you’re seeing the fund as the listed donor, not the wealthy individual behind it. Researching who manages that fund sometimes reveals the actual funding source, though donor names can remain completely anonymous in these arrangements.
Foundation grants often come with public information about the grant award and its purpose. If a nonprofit lists a foundation as a major funder, you can search that foundation’s website or check Foundation Center databases to find the specific grant. This research shows what the nonprofit promised to accomplish with the grant money and whether they actually delivered results.
You can also investigate nonprofit networks and partnerships to understand funding flows. Large nonprofits sometimes create separate organizations for different programs or to accept certain types of funding. Money might flow between these related organizations in ways that aren’t obvious from a single Form 990, so research whether the nonprofit you’re studying has affiliated organizations or subsidiaries.
Understanding Different Types of Nonprofit Structures
Nonprofits organize themselves in different ways, and each structure affects funding disclosure requirements. A 501(c)(3) public charity must file Form 990 and disclose major donors to some extent. A 501(c)(4) social welfare organization has different reporting requirements and more flexibility in hiding donor identities.
Private foundations have the most stringent disclosure requirements of any nonprofit type. A private foundation receiving funding and distributing grants to other nonprofits must file Form 990-PF, which lists all grants distributed. This means if you trace funding back to a private foundation, you can see exactly where that foundation sent its money.
Donor-advised funds occupy a middle ground in terms of transparency and regulation. These funds accept donations from wealthy individuals and then distribute grants to nonprofits recommended by the donor. The donor-advised fund files Form 990, but the fund sponsor might not disclose which individual recommended each grant.
Religious organizations that qualify as churches have special exemptions from Form 990 filing requirements. This means donations to a church don’t appear in the same public databases as donations to secular nonprofits. However, states sometimes require churches to file separate financial disclosures, so checking state records provides additional information.
Understanding these structural differences helps you interpret what information is available and what remains private. A nonprofit’s organizational structure partly determines what funding information must be disclosed. If you can’t find detailed funding information about a nonprofit, the structure of that organization might explain why certain disclosures don’t exist.
Mistakes to Avoid When Researching Nonprofit Funding
Assuming Form 990 shows all donors. Many people think Form 990 lists every person and organization that gave money, but actually only donors of $5,000 or more appear in Schedule B. Nonprofits can receive millions in small donations that don’t get individually named. Don’t assume a nonprofit has few donors just because the Form 990 lists only a handful of names.
Ignoring in-kind donations and grants. Form 990 shows cash donations but sometimes lists in-kind contributions (like donated goods, services, or volunteer time) separately or not at all. This can make a nonprofit’s actual funding appear smaller than it really is. A food bank that receives millions in donated food might show lower cash revenue than they actually handle.
Confusing revenue with funding. Nonprofits get revenue from many sources: program fees, membership dues, fundraising events, and grants. Revenue from program fees isn’t the same as funding from donors. If a health clinic charges patients a small fee, that fee counts as revenue but not as charitable funding.
Missing state registration information. Some people only check federal IRS databases and miss important state-level funding disclosures. State attorneys general sometimes require nonprofits to file supplemental reports with funding details not on Form 990. Checking your state’s charity registration database gives you additional funding information.
Assuming lack of transparency means wrongdoing. A nonprofit might have legitimate reasons for accepting anonymous donations, such as protecting donor privacy or religious reasons. However, if a nonprofit refuses to provide Form 990 when requested, that’s a genuine red flag. The difference is between legal privacy and unlawful secrecy.
Trusting only one information source. Don’t rely solely on what a nonprofit tells you about their funding. Compare their claims to their Form 990, annual report, and state filings. If a nonprofit claims they’re “mostly grassroots funded” but Form 990 shows 80% of money comes from a single foundation, that’s a problem.
Overlooking related organizations and networks. Large nonprofits sometimes create separate organizations for different programs or to accept certain types of funding. Money might flow between these related organizations in ways that aren’t obvious from a single Form 990. Research whether the nonprofit you’re studying has affiliated organizations or parent companies.
Ignoring changes in funding over time. Nonprofits sometimes shift their funding sources dramatically from year to year. Examining only the most recent Form 990 misses important trends. If a nonprofit suddenly shifts from government funding to foundation funding, that change might indicate policy disagreements or new strategic direction.
Forgetting about grant restrictions and conditions. A grant from a foundation might come with strings attached that limit how the nonprofit operates. Understanding not just who funds an organization but what conditions they impose on funding helps you see potential donor influence. Check grant announcements to find what conditions applied to major donations.
Do’s and Don’ts for Researching Nonprofit Funding
| Do | Don’t |
|---|---|
| Check the most recent three years of Form 990 | Rely only on nonprofit’s own website |
| Verify claims by cross-referencing multiple sources | Assume nonprofit status means legitimate |
| Research board members and their affiliations | Overlook state-level charity registration |
| Read the narrative section of Form 990 | Ignore red flags like refusing Form 990 |
| Ask the nonprofit directly about funding sources | Assume hidden donors always mean illegal |
| Compare funding to similar organizations nearby | Stop researching after checking one database |
| Look at whether funding sources have changed | Trust marketing claims without verification |
| Examine grants listed on foundation websites | Confuse revenue with donor contributions |
Pros and Cons of Different Funding Sources
| Funding Source | Pros and Cons |
|---|---|
| Individual Donations | Shows grassroots support; unpredictable |
| Government Grants | Large, stable amounts; creates reporting burden |
| Foundation Grants | Prestigious funders; restrictive requirements |
| Corporate Sponsorships | Significant funding; risk of mission drift |
| Earned Revenue | Independent funding; may limit access |
| In-Kind Donations | Saves cash; hard to track valuations |
The Role of State Attorneys General in Nonprofit Oversight
State attorneys general oversee nonprofits registered to fundraise within their state and have enforcement power over disclosure violations. Each state maintains a charity registration database where nonprofits must file annual financial reports. These state filings sometimes require more detailed funding information than federal Form 990 requires, providing additional transparency.
If you suspect a nonprofit is misrepresenting its funding sources or hiding donor information illegally, you can file a complaint with your state attorney general. The National Association of State Charity Officials coordinates these oversight efforts across states. State investigations can result in nonprofits being required to refund donations or losing their right to fundraise.
Some states require nonprofits to disclose how much money they spent on fundraising versus programs. This information appears on state filings but might not be as prominently displayed on Form 990. A nonprofit that spends 70% of donations on fundraising instead of programs should raise concerns about financial management.
States also track nonprofit compliance with registration requirements and timely filing of annual reports. A nonprofit that fails to file state reports or register to fundraise is breaking state law, even if they’re exempt from federal taxes. These state compliance records give you another way to evaluate nonprofit legitimacy.
Finding Information About Nonprofit Leadership and Salaries
Form 990 requires nonprofits to disclose the salaries of their highest-paid officers and employees. This information helps you understand how an organization spends money and whether leadership compensation is reasonable. The salary disclosure section shows how much money goes to paying executives versus program services.
You can research nonprofit leaders to understand potential conflicts of interest or funding relationships. If the executive director previously worked in the corporate world and their former company now donates to the nonprofit, that’s a connection worth investigating. LinkedIn and professional databases help you trace these relationships.
Nonprofits sometimes have officers or board members who sit on multiple nonprofit boards simultaneously. This interconnected leadership structure might explain funding relationships between organizations. Research whether funding appears to flow in predictable directions based on leadership relationships.
Compensation data from Form 990 sometimes reveals whether organizations pay market-rate salaries or underpay staff. While lower salaries might seem to indicate more money goes to programs, extremely low compensation might result in staff turnover and reduced effectiveness. Understanding salary context helps you evaluate the nonprofit’s overall financial health.
Using Watchdog Organizations to Research Nonprofit Funding
Nonprofit watchdog organizations evaluate nonprofits based on their financial health, transparency, and program effectiveness. Sites like Charity Navigator and GiveWell analyze Form 990 data and provide ratings. These organizations sometimes uncover funding patterns and donor relationships that individual researchers might miss.
Watchdog organizations often publish investigations into nonprofit funding that goes beyond standard Form 990 analysis. If you find a nonprofit marked as “low transparency” or “unclear funding sources” by a watchdog, that’s a sign to dig deeper. These organizations provide summaries that make complex funding information more accessible to ordinary donors.
You can search watchdog sites by nonprofit name to find detailed analysis of their funding and financial practices. These analyses often explain what the funding patterns mean for program effectiveness and organizational health. However, remember that watchdog organizations sometimes have their own biases, so compare multiple sources.
Financial analysis by watchdogs includes information about nonprofit revenue trends and whether an organization is growing or shrinking. This trend information helps you understand whether a nonprofit has sustainable funding or relies on one-time major grants. A nonprofit showing consistent revenue growth might indicate stronger funding relationships.
Connecting Funding to Nonprofit Outcomes and Effectiveness
Understanding who funds a nonprofit matters partly because of how funding shapes organizational priorities and outcomes. A nonprofit that receives most funding from a single foundation might feel obligated to prioritize that funder’s goals over community needs. Researching funding sources helps you see whether mission and funding align.
Nonprofits sometimes measure their impact based on metrics that match their major funders’ priorities rather than measures most important to the communities they serve. If a nonprofit suddenly changes what it measures and reports, look at whether funding sources changed. Funding relationships influence what nonprofits do and how they measure success.
Government-funded nonprofits must meet compliance requirements and reporting standards set by the government agencies funding them. This can create either stability (if government funding continues) or instability (if government priorities shift). Understanding the role of government funding explains how policy changes affect nonprofit operations.
Foundation-funded nonprofits sometimes face pressure to demonstrate outcomes within the timeframes and metrics that foundations require. This can push nonprofits to show quick results rather than build long-term solutions. Researching a nonprofit’s funding helps you understand whether reported outcomes reflect genuine impact or funder expectations.
How Nonprofit Funding Affects Access and Equity
The sources of nonprofit funding sometimes determine who gets served and who gets left out. A nonprofit funded primarily by wealthy donors might serve affluent neighborhoods because that’s where donors want to see impact. Research the geographic distribution of a nonprofit’s funding to understand whether it matches their stated service area.
Nonprofits relying on user fees or earned revenue sometimes exclude low-income people who can’t pay. A community center that charges membership fees funded by wealthy members might not serve homeless populations who need their services most. Understanding funding sources reveals potential equity problems in nonprofit service delivery.
Some funding sources come with explicit restrictions about who can receive services. Government funding sometimes requires nonprofits to document citizenship or residency status of clients. Religious funding sometimes requires nonprofits to provide services in ways consistent with religious teachings.
Nonprofit diversity and inclusion efforts partly depend on funding available for hiring and training staff from underrepresented communities. A nonprofit without dedicated funding for diversity initiatives likely has homogeneous staff and leadership. Researching funding sources shows whether organizations prioritize equity in their operations.
FAQs
Can I find out who donated to a specific nonprofit?
Yes, but only if they donated $5,000 or more. Schedule B of Form 990 lists major donors’ names. Smaller donors aren’t individually named, and some donors can request anonymity.
How often do nonprofits file Form 990?
Yes, nonprofits must file annually. The IRS requires annual filing for nonprofits with gross receipts over $50,000. Smaller nonprofits might file simplified forms or state-only returns.
What if a nonprofit refuses to give me Form 990?
They can’t refuse. Federal law requires nonprofits to provide Form 990 within 30 days of your request. You can file a complaint with your state attorney general if they refuse.
Are all nonprofit donations tax-deductible?
No, only donations to IRS 501(c)(3) organizations are tax-deductible. Donations to 501(c)(4) social welfare groups or 527 political organizations aren’t deductible for federal taxes.
Can foreign donors fund US nonprofits?
Yes, but with restrictions. Foreign individuals and corporations can donate to 501(c)(3) nonprofits, though nonprofits must track these donations carefully for compliance.
Do religious nonprofits have to disclose funding?
No, some religious organizations are exempt from filing Form 990. However, those with unrelated business income must still file. State registration requirements might still apply.
What’s the difference between a 501(c)(3) and a 501(c)(4)?
Both are nonprofits, but 501(c)(3)s can give tax deductions and are more restricted. 501(c)(4)s can engage in unlimited political activity but donors don’t get tax deductions.
How do I know if a nonprofit is actually registered?
Search the IRS database using the IRS Tax Exempt Search tool. Also check your state attorney general’s charity registration database for additional verification.
Can a nonprofit hide their real funding source?
Partially yes. Nonprofits can use donor-advised funds, accepting money from intermediaries instead of named individuals. However, shell nonprofits that only pass money through face IRS scrutiny.
What if Form 990 numbers don’t match the nonprofit’s annual report?
Investigate the difference. Different accounting methods can explain discrepancies, but large gaps suggest problems. Contact the nonprofit directly or file a complaint with IRS Criminal Investigation if you suspect fraud.
