What Is General Operating Support? A Guide for Nonprofits

General operating support (GOS) is funding that supports a nonprofit organization as a whole rather than paying for a specific program or project. Also called unrestricted or core support, general operating funding typically gives a nonprofit flexibility to decide how grant dollars can best advance its mission.

That can mean paying staff, keeping the lights on, investing in technology, strengthening fundraising, delivering programs or responding to an unexpected community need. The central idea is simple: Instead of a funder deciding that its grant must pay for one narrowly defined activity, the nonprofit has greater discretion over how to put the money to work.

For nonprofits, this flexibility can be enormously valuable. But grantseekers should also know that general operating support can be harder to secure than project funding, particularly from a new funder.

What can general operating support pay for?

General operating support can help cover the full range of expenses involved in running a nonprofit and advancing its mission. Depending on the grant agreement, that can include:

• Staff salaries and benefits;
• rent, utilities and facilities;
• finance and accounting;
• technology and software;
• fundraising and development;
• communications;
• insurance;
• staff or leadership development;
• strategic planning; program delivery;
• organizational growth;
• and unexpected expenses or emerging community needs.

This is one reason nonprofits prize unrestricted funding. A nonprofit does not consist of isolated programs. Programs depend on staff, technology, financial management, fundraising, communications and organizational leadership to succeed.

Consider a nonprofit museum that receives a project grant to run school tours. The grant might pay museum educators who conduct the tours. But the organization still needs someone to process payroll, maintain the building, manage technology, raise additional money and communicate with schools. General operating support can help fund the infrastructure that makes the program possible in the first place.

It is also important not to think of GOS as merely “overhead funding.” General operating grants may support administrative expenses, but they can also pay for programs and direct services. What distinguishes GOS is flexibility, not the type of expense involved.

A nonprofit should nevertheless read the grant agreement carefully. A grant described as operating support may still carry a specified grant period, reporting requirements or other conditions.

General operating support vs. project support: what’s the difference?

The fundamental difference between general operating support and project support is what the grant is intended to fund.

With program or project support, the funder and nonprofit agree that grant dollars will be used for a specified activity. If a foundation awards $100,000 to expand a youth mentoring program, for example, the nonprofit generally cannot decide halfway through the grant period to spend that money on an unrelated initiative.

A $100,000 general operating grant works differently. Subject to the terms of the grant agreement, the nonprofit has considerably more freedom to determine where those dollars will do the most good.

That flexibility is valuable because circumstances change. A program may cost less than anticipated. Rent may rise. A staff vacancy may need to be filled. A community crisis may suddenly demand attention. Unrestricted funding gives nonprofit leaders more room to respond.

For a deeper look at the arguments on both sides, see Inside Philanthropy’s guide to general operating support versus project support and its donor report on GOS and project funding.

Is general operating support the same as unrestricted funding?

In philanthropy, general operating support and unrestricted support are commonly used interchangeably. The actual grant agreement determines how funds may be used.

It’s also useful to distinguish an unrestricted organizational grant from a project grant that includes generous indirect costs. A project grant may help pay for administrative expenses associated with the project, but the underlying funding is still restricted to that project.

Is general operating support always multiyear?

No, general operating support describes what funding supports. Multiyear funding describes how long the funder commits to providing it.

A foundation might make a one-year general operating grant, a three-year general operating grant or a three-year project grant.

Multiyear funding means funding is committed for two or more years. When a grant is both multiyear and unrestricted, nonprofits gain two kinds of flexibility at once: discretion over how to use the money and greater predictability about future revenue.

That combination can make it easier to retain staff, plan strategically, make longer-term investments and spend less organizational energy continually replacing expiring grants. The Center for Effective Philanthropy has documented nonprofit leaders’ strong preference for multiyear general operating support.

How is general operating support different from capacity-building support?

General operating support and capacity-building funding can overlap, but they are not the same thing.

Capacity-building support is usually intended to strengthen some aspect of an organization’s ability to operate effectively over the long term. That might include upgrading technology, developing a strategic plan, training leaders, strengthening a board or improving fundraising systems.

General operating support may be used for those purposes, but it does not have to be. A nonprofit could use unrestricted funding for capacity building, program delivery, salaries, rent or any number of other organizational needs.

A dedicated capacity-building grant therefore says, in effect, “Use these dollars to strengthen this part of your organization.” General operating support says, more broadly, “Use these dollars to advance the organization and its mission.”

Why do nonprofits prefer general operating support?

General operating support gives nonprofit leaders more control over how to run their organizations. That matters because nonprofit leaders generally have more day-to-day knowledge of their organizations and communities than their funders do. They know when a program needs additional staff, when aging technology is slowing down service delivery or when a sudden need in the community demands a different response.

Restricted grants can certainly fund valuable work. But problems arise when too much of an organization’s budget is locked into narrowly defined projects while essential costs remain unfunded.

A nonprofit may have enough grants to operate six programs, but too little flexible money to pay its finance staff. It may receive funding to launch an initiative, but not to improve the technology needed to administer it. Or staff may find themselves continually writing proposals for new projects because few funders will help sustain the organization already carrying out the work.

Inside Philanthropy has examined how excessive reliance on restricted project grants can also distort nonprofit priorities when organizations feel pressure to design work around what funders want rather than what communities or nonprofit leaders believe is most needed.

General operating support does not eliminate fundraising pressures or guarantee organizational effectiveness. But it gives nonprofits greater leeway in making those choices themselves.

Why don’t all foundations provide general operating support?

From the funder’s perspective, project grants can offer something GOS does not: a clearly bounded use for the money.

A foundation may want to support a particular issue, intervention or initiative rather than an entire organization. Project funding can also make it easier for a funder to associate a grant with defined activities, budgets and outcomes. Some foundations also use project grants to begin relationships with organizations they have not funded before. A funder may support one initiative, learn more about the organization and only later consider providing broader support.

A foundation’s willingness to award general operating support does not necessarily mean every prospective grantee has equal access to it. A funder may give unrestricted support primarily to organizations it knows well while offering project grants to newer partners. Its published guidelines may also differ from its actual grantmaking patterns. This is why prospect research matters.

What do foundations look for when awarding general operating support?

There is no single formula. Foundation grant decisions vary widely depending on the institution, board, staff, strategy and grantmaking process. But because unrestricted funding supports the organization as a whole, funders considering GOS often need confidence in more than one program.

Mission alignment

For general support, alignment between the nonprofit’s overall mission and the funder’s priorities can be especially important. A project funder can support one initiative even if the rest of an organization’s work falls outside its interests. General operating support makes that separation harder. Grantseekers should therefore be able to explain why the organization itself — not merely one program — advances the funder’s goals.

Organizational effectiveness and track record

Funders may consider whether an organization appears capable of delivering on its mission. That can include leadership, past accomplishments, program quality, community relationships and evidence that the nonprofit understands the population or issue it serves.

Financial health and organizational capacity

General operating requests often require grantmakers to examine the organization’s broader financial picture. Applicants may be asked for an annual operating budget, audited financial statements, revenue sources, other funders and information about financial controls.

Financial strength does not necessarily mean having a large budget or enormous reserves. But a nonprofit should be prepared to explain its finances clearly and show that it can responsibly steward grant funds.

Leadership and governance

Funders may also assess executive leadership, staff capacity and board governance. For some grantmakers, confidence in nonprofit leadership is an important part of deciding whether to provide flexible support.

The existing funder-grantee relationship

This factor shouldn’t be underestimated. General operating support frequently rests on confidence developed through previous grants, conversations or knowledge of an organization’s work. That means an existing funder that already supports one of your programs may sometimes be a better GOS prospect than a foundation that has never funded you before.

Is general operating support a form of trust-based philanthropy?

General operating support is closely associated with trust-based philanthropy, but the terms are not synonymous.

The Trust-Based Philanthropy Project identifies multiyear unrestricted funding as one of six grantmaking practices associated with a trust-based approach. Other practices include streamlining paperwork, doing more of the research burden on the funder’s side, being transparent and responsive, soliciting feedback and offering support beyond the grant itself.

Unrestricted funding reflects an important principle behind trust-based philanthropy: Nonprofit leaders and communities should have meaningful authority over how resources are used. But simply making one unrestricted grant does not automatically make a funder “trust-based.” A foundation can provide general support while retaining cumbersome application processes, imposing burdensome reporting requirements or maintaining highly transactional relationships with grantees.

Trust-based philanthropy is a broader approach to the relationship between funders, nonprofits and communities.

Is general operating support becoming more common?

There are signs that flexible funding has gained significant ground.

Historically, general operating support represented a relatively small share of institutional grantmaking. But the 2025 National Study of Philanthropic Practice from Grantmakers for Effective Organizations found that the median share of grantmaking budgets devoted to GOS had risen to 38%, after hovering around 20% for nearly two decades. The study drew responses from 765 grantmakers.

Multiyear funding has also grown. GEO reported that 87% of responding grantmakers provided some multiyear support in 2025, compared with 79% in 2014 and 2017.

Inside Philanthropy has also covered the recent rise in general operating support and the broader shift toward more flexible grantmaking.

Still, grantseekers should interpret those trends carefully. An increase in the share of funding devoted to GOS does not mean that unrestricted grants are readily available to every nonprofit or that most open grant opportunities offer GOS. Some foundations make unrestricted grants selectively, including to longstanding partners, while continuing to offer restricted grants elsewhere in their portfolios.

How can nonprofits find general operating support grants?

Start with the same principle that should guide all good prospect research: Look for evidence of fit, not simply a funder’s stated interests.

When researching a potential funder, determine whether it makes general operating grants, who receives them, how large those grants tend to be, whether they are one-year or multiyear, and whether unrestricted funding appears to go mainly to existing grantees.

Past grantmaking can be revealing. Private foundations disclose grants on their Form 990-PF filings, and grant descriptions may use terms such as “general operating support,” “general support,” “unrestricted support” or “core support.” But 990 data is only one part of the picture. It can tell you what a foundation funded in the past; it may not tell you whether priorities have changed, whether an application is open, how relationships affect grantmaking or what kind of organization is most competitive today.

Inside Philanthropy’s guide to finding grants for your nonprofit explains how to combine funding history with research on a foundation’s priorities, accessibility, geography, grant sizes and giving approach.

For a GOS prospect in particular, investigate the pattern behind the grants. If a foundation gives unrestricted support only after several years of project funding, that is valuable intelligence. If most comparable nonprofits in its portfolio receive operating support, that tells you something different.

The IP Take

General operating support has long been one of philanthropy’s most requested—and debated—forms of funding. Its strength isn’t simply that it pays for overhead. GOS recognizes that programs don’t operate independently from the organizations running them. Strong programs depend on staff, technology, financial management, communications, fundraising and leadership.

But grantseekers shouldn’t assume that a foundation describing itself as a supporter of flexible funding will readily award unrestricted grants to newcomers. In practice, many funders reserve GOS for organizations they already know well. Prospect research should therefore examine not only what a funder says about unrestricted support, but who actually receives it, how long those relationships have existed and whether comparable organizations have received similar grants.
