How to Secure Corporate and Business Support: A Practical Guide for Grant Writers and Development Staff

Executive Summary

Corporate giving reached a record $44.4 billion in the United States in 2024, growing more than 9 percent year over year — and a substantial share of it is available to nonprofits that know how to pursue it. Most don’t, not because the opportunity isn’t real but because corporate giving is genuinely confusing, and most grant writers have been given no framework for navigating it. The same company might have a foundation, a CSR (Corporate Social Responsibility) budget, a matching gift program, and a local sponsorship budget — all managed by different people, all requiring different approaches, and all sitting behind a different door. This paper gives grant writers and development staff a clear, practical framework for getting corporate money — starting with the four doors that organize everything, then a readiness assessment that tells you which door to approach first, then the specific research and proposal skills that open each one. External resources are named throughout so that practitioners who want to go deeper know exactly where to look.

Section 1 of 6 — What You Are Actually Dealing With: The Four Doors Into Corporate Money

Before writing a single proposal, a grant writer needs to understand which type of corporate relationship they are pursuing — because each one requires a different approach, involves a different decision-maker, and moves on a different timeline. The simplest way to organize this is not by instrument type but by door: the four ways into corporate money, named for the relationship they require.

The Community Door: Local Business Sponsorships and Event Support

The community door is the most accessible entry point for most nonprofits, and it is entirely relationship-driven. A local restaurant that sponsors the annual gala, a regional bank that underwrites the holiday appeal, a law firm whose name appears on the event program — these are community door relationships, and the key that opens them is almost never a proposal. It is a personal connection: a board member who calls a fellow business owner, a volunteer who mentions the organization to her employer, an executive director who has spent years building presence in the local business community.

The community door is also the most fragile. Local sponsorships tend to be tied to individual relationships rather than institutional commitments, which means they can disappear when the contact moves on or the relationship cools. A gala sponsor who gave $5,000 three years in a row because the development director knew the owner personally may not renew when that development director leaves — unless the relationship has been widened to include multiple contacts at the company.

What the nonprofit needs to open this door: a board that is genuinely engaged in outreach, a tiered sponsorship package with clear benefit levels, and a written agreement that formalizes what both parties expect. The National Council of Nonprofits (councilofnonprofits.org) provides a readiness checklist and guidance on structuring the agreement.

The CSR Door: Grants from the Company’s Community Affairs or CSR Budget

Corporate Social Responsibility — CSR — is the framework through which companies articulate and manage their social impact. Most companies of meaningful size have a CSR or community affairs department whose job is to deploy the company’s philanthropic budget in ways that align with its stated values and priorities. These departments make grants, sponsor programs, support employee volunteer initiatives, and manage the company’s community relationships.

The CSR door requires a proposal, but the proposal that opens it is structurally different from a foundation proposal. The CSR reader is not a program officer with a deep interest in the field — they are a corporate professional whose job is to find programs that align with the company’s stated priorities, produce outcomes the company can report to its stakeholders, and reflect well on the company’s brand. A proposal that speaks to the company’s own stated language and commitments will be read differently than one that leads with the nonprofit’s needs.

The timeline for CSR grants varies significantly by company — some operate on a calendar year cycle, others on a fiscal year that may end in March, June, or September — and many make their budget decisions in the fourth quarter for the following year. A grant writer who contacts a CSR department in January may already be too late for that year’s budget. Section 3 of this paper covers the research; Section 5 covers the proposal.

The Foundation Door: Grants from the Company’s Private Foundation

Larger companies often have a legally separate private foundation established to manage their philanthropy. This foundation files a Form 990-PF — where PF stands for Private Foundation — with the IRS, just as an independent foundation does, and it can be researched through the same tools: Candid’s Foundation Directory Online (candid.org) and ProPublica’s Nonprofit Explorer (projects.propublica.org/nonprofits).

It is important to understand that a company’s foundation and its direct CSR giving are separate channels — they may fund different types of organizations, at different levels, for different purposes. A grant writer who submits the same proposal to both without adjusting for the difference is making a structural mistake that signals a lack of research to both readers. For a full treatment of foundation research and proposal writing, see the companion white paper in this series: Foundation Fundraising for Nonprofits: A Complete Guide for Grants Managers.

The Workplace Door: Matching Gifts, Volunteer Grants, and Payroll Giving

The workplace door is the most underused of the four, and it is uniquely accessible because it does not require building a new corporate relationship at all. It operates through existing donors and volunteers whose employers have programs in place that the nonprofit has simply never activated.

Employee matching gift programs allow companies to match their employees’ charitable contributions, typically dollar for dollar, though some companies match at two-to-one or three-to-one ratios. Total donations through corporate grants and workplace giving programs on Benevity reached $3.74 billion in 2025, representing a 9.2 percent increase over 2024. Despite this scale, matching gifts remain one of the most underutilized sources of revenue in nonprofit fundraising, largely because donors do not know their employer has a matching program and nonprofits do not actively promote that they are eligible for one.

Volunteer grants — sometimes called dollars for doers — are grants made by companies to nonprofits where their employees volunteer, typically at a rate of $10 to $25 per volunteer hour. These are available to virtually any nonprofit with an active volunteer program, yet most organizations fail to claim them because they do not track volunteer hours systematically or remind volunteers to submit grant requests.

What the nonprofit needs for the workplace door: registration on the major workplace giving platforms (Benevity, YourCause, CyberGrants, Bonterra), a system for tracking volunteer hours, and active promotion of matching gift eligibility in acknowledgment letters, on the website donate page, and at events. Double the Donation (doublethedonation.com) is the sector’s leading database for matching gift and workplace giving programs.

Section 1 action step: Before moving to research or proposals, map your four doors. Which ones does your organization currently have open? Which are entirely unactivated? The answer determines where to invest the next ninety days of corporate giving effort.

Section 2 of 6 — Where to Start: A Simple Readiness Assessment

The most common mistake in corporate giving is starting with the most visible companies rather than the most accessible opportunities. A grant writer who begins by researching Fortune 500 CSR budgets, when the organization’s board has no corporate connections and its donors work mostly at small and mid-size businesses, has inverted the sequence. The right starting point is determined by three questions answered in order.

Question One: What does your existing donor and volunteer list tell you?

Pull the employer information from your donor and volunteer records. Which companies already have employees who care enough about your mission to give their own money or time? These are the organizations most likely to match those gifts, grant volunteer hours, and eventually consider a CSR investment. A nonprofit whose donor list includes 40 employees of a single regional hospital system has a matching gift and volunteer grant opportunity sitting in its own database, regardless of whether that hospital has any formal relationship with the nonprofit.

This is the workplace door, and it is almost always the fastest first move regardless of organizational stage. The cultivation work has already been done by the individual donor relationship — activating the corporate program is a matter of promotion and process, not new relationship building.

Practical steps: add an employer field to your donation form and event registration, survey your top 100 donors to collect employer information, and check those employers against Double the Donation’s database to identify which have matching programs and at what ratios.

Question Two: Which board members, volunteers, or major donors have direct relationships with business owners or corporate executives?

This question opens the community door and, sometimes, the CSR door. The board gift matrix exercise — asking each board member to list the companies where they have direct relationships and indicate the nature of those relationships — is the most efficient tool for answering this question. It surfaces connections that are invisible to the development director and often reveals corporate relationships that board members have never thought to mention because nobody asked.

Practical steps: add a corporate relationships question to the annual board self-assessment, ask the board chair to raise the subject at a board meeting framed as a cultivation mapping exercise, and document every connection in the CRM as a corporate prospect record linked to the board member who identified it.

Question Three: Which companies in your region or sector have publicly stated priorities that align with your mission?

This is the research question that opens the CSR and foundation doors, and it comes third — not because it is least important, but because it requires the most cultivation investment and produces the slowest returns. A grant writer who spends three months researching CSR reports before activating the matching gift program in their existing donor base has prioritized the hardest work over the easiest money. Section 3 of this paper covers this research in full.

Section 2 action step: Complete the readiness assessment before advancing. Which of the three questions has the most immediately actionable answer for your organization right now? Begin there, not with the question that sounds most impressive.

Section 3 of 6 — How to Research Companies Worth Approaching

Once the readiness assessment has identified which corporate doors are accessible, the research process determines which specific companies to approach through each one. The tools and techniques differ by door.

Researching the Community Door: Know Your Local Business Landscape

Local business sponsorship research begins with the business community your organization already inhabits. Chamber of commerce member directories, local business journals’ annual lists of largest employers, neighborhood business associations, and the sponsor lists from comparable organizations’ events all provide a starting map. A company that has sponsored three other nonprofits’ galas in the past two years is a company with an established habit of local event sponsorship, a person who manages that decision, and a budget line already allocated for it. That is a warmer prospect than a company with no documented philanthropic history in the community, regardless of the company’s size.

Researching the CSR Door: Reading What Companies Have Publicly Committed To

CSR reports — sometimes called sustainability reports, impact reports, or community reports — are annual documents in which companies describe their philanthropic priorities, their community investments, and the outcomes they aim to produce. They are almost always publicly available on the company’s website, typically under a tab labeled “Responsibility,” “Sustainability,” “Impact,” or “Community.” For a grant writer, the CSR report is the most important research document available before approaching a company’s community affairs department.

What to look for: the company’s stated priority areas, any geographic focus, the types of organizations previously funded, typical grant ranges, and the name of the staff member responsible for community giving. A proposal that uses the company’s own language from its CSR report, and that positions the nonprofit’s work as advancing the outcomes the company has publicly committed to produce, will be read as the work of a sophisticated grant writer rather than a mass-submission applicant.

Environmental, Social, and Governance reporting — known as ESG — is a related but distinct framework used by publicly traded companies to disclose their social impact performance to investors and rating agencies. Where a CSR report describes what a company does philanthropically, an ESG report describes what a company has measurably committed to achieving. When a company’s ESG report commits to reducing food insecurity in the communities where it operates, a nonprofit whose mission advances food security has been handed the language of their proposal by the company itself. ESG reports are available through company investor relations pages, the Global Reporting Initiative database (globalreporting.org), and the SASB disclosure platform (sasb.org).

Researching the Foundation Door: The 990-PF Analysis

A corporate foundation’s Form 990-PF discloses the foundation’s complete grants list for the most recent fiscal year — every grantee, every amount, and in most cases a brief description of the grant’s purpose. Reading this list tells a grant writer more about the foundation’s actual priorities than any published guideline. Key questions: What is the average grant size? Is there a geographic concentration? Are the grantees predominantly large established organizations, or does the foundation also fund smaller ones? ProPublica’s Nonprofit Explorer (projects.propublica.org/nonprofits) provides free access to recent 990-PF filings. Candid’s Foundation Directory Online (candid.org) provides a more structured research environment, available by subscription or through many public library systems.

Researching the Workplace Door: Your Donor Data and Double the Donation

The primary research tool for the workplace door is your own donor and volunteer database, cross-referenced against Double the Donation’s matching gift database (doublethedonation.com). A grant writer who checks the top 100 donors’ employers against this database will almost always find that a meaningful percentage work for companies with active matching programs. A personal note from the development director — “Your employer may match your gift to us, potentially doubling its impact. Would you like help looking that up?” — produces both matches and donor goodwill.

Section 3 action step: Choose one research task to complete this week. If you have not pulled your donor employer data, do that first. If you have it but have not cross-referenced it against Double the Donation, do that second. If both are done, read one CSR report from a company you have been meaning to approach and note three specific alignments between their stated priorities and your organization’s work.

Section 4 of 6 — The Tax Rule Every Grant Writer Must Know Before Accepting a Sponsorship

The community door carries a tax trap that catches many nonprofits by surprise. A grant writer who does not understand it before signing a sponsorship agreement may inadvertently expose the organization to UBIT — Unrelated Business Income Tax.

The core principle, drawn from National Council of Nonprofits guidance, is this: not all corporate sponsorship income is automatically tax-exempt for a nonprofit. The IRS distinguishes between a qualified sponsorship payment — which is tax-exempt — and advertising income — which is taxable as unrelated business income (UBI). The distinction turns on whether the corporate sponsor receives a “substantial return benefit” for its payment beyond simple acknowledgment of support.

What counts as tax-exempt acknowledgment:

A nonprofit can acknowledge a corporate sponsor with the company’s name, logo, general phone number, locations, and internet address in printed materials, on the website, or at events. A verbal thank you from the podium at a gala is acknowledgment. A banner displaying the sponsor’s name and logo is acknowledgment. These do not create taxable income.

What crosses into taxable advertising:

Qualitative or comparative language about the sponsor’s products is advertising. Promising exclusivity to a sponsor automatically triggers a finding of substantial return benefit because the IRS considers exclusivity to be a significant benefit. A link from the sponsor’s logo on the nonprofit’s website that goes to a product purchase page rather than the company’s home page is advertising. A full-page advertisement in the conference program with text written by the company promoting its services is advertising, even if it is called a “sponsorship recognition page.”

The practical implication:

Before signing any sponsorship agreement that includes recognition benefits, apply one diagnostic question: does this benefit function as acknowledgment (it describes who the sponsor is) or as advertising (it promotes what the sponsor sells)? If any element functions as advertising, that portion of the sponsorship payment may need to be reported as taxable income on IRS Form 990-T. The full guidance is available from the National Council of Nonprofits at councilofnonprofits.org. A brief review with the organization’s accountant or attorney before finalizing a sponsorship package costs far less than discovering the tax exposure after the fact.

Section 4 action step: Review your current sponsorship packages and any existing agreements. For each recognition benefit, apply the acknowledgment versus advertising test. Flag any that include qualitative language about the sponsor’s products, exclusivity promises, or product purchase links, and discuss them with your accountant before the next renewal.

Section 5 of 6 — How to Make the Ask: Corporate Proposals Are Not Foundation Proposals

The grant writer who submits a foundation-style proposal to a CSR department — five to eight pages, narrative-heavy, academically framed — is sending a signal that they do not understand who they are writing for. The corporate reader is a corporate professional who may be reviewing dozens of proposals in a week, who reports to a marketing or communications executive, and who is evaluating whether supporting this organization will align with the company’s stated priorities, reflect well on the company’s brand, and produce outcomes the company can report in its own CSR and ESG disclosures.

The corporate proposal: structure and length

A corporate proposal is typically one to three pages. It leads with a single paragraph that connects the organization’s work to the company’s specific stated priorities, using the language of the company’s own CSR report where possible. It names the specific program or population being supported, describes the outcomes in measurable terms — numbers of people served, specific changes produced, economic value generated — and closes with the ask: a dollar amount, a timeline, and what the funding will produce. It does not include organizational history beyond a single sentence, lengthy statements of need that assume the reader already cares deeply, or academic citations.

The cover letter is the proposal

In many corporate giving contexts, particularly local sponsorships and CSR department introductions, the cover letter is effectively the entire proposal. A one-page letter that identifies the alignment between the organization’s mission and the company’s priorities, describes the specific program and ask, and invites a follow-up conversation will be read and responded to. A full proposal submitted cold to a company with which no relationship exists will often not be read at all. The sequence that works: a brief introductory email or call to confirm the right contact and that a proposal would be welcome, followed by the one-page letter, followed by a follow-up call two weeks later.

The matching gift conversation belongs in every corporate relationship

Every time a grant writer closes a corporate grant — regardless of which door it came through — there is a matching gift conversation to have. Does the company have a matching gift program that could apply to employee donations to the organization? Is the organization registered on the company’s giving portal? Have the organization’s individual donors who work at this company been told that their gifts may be eligible for a match? This conversation costs nothing and requires no proposal. It layers an additional revenue stream onto a corporate relationship that is already open.

A note on the preliminary conversation

For the CSR and foundation doors, a brief preliminary conversation before submitting — to confirm alignment, to identify the right contact, and to ask whether a proposal would be welcome — is worth more than any amount of polish on the proposal itself. A CSR coordinator who has spoken with a grant writer before the proposal arrives reads that proposal differently than one who receives it cold from a name they don’t recognize.

Section 5 action step: If your organization has an existing corporate relationship — even a modest one — call or email that contact this week. Ask whether the company has a matching gift program, whether there are employee volunteer opportunities that might qualify for volunteer grants, and whether the contact would be willing to make a brief introduction to the CSR or community affairs department. You already have the relationship. Use it.

Section 6 of 6 — Tracking, Follow-Up, and Building the Pipeline

A corporate giving program that lives in the grant writer’s head is a program that disappears when the grant writer leaves, and a program that produces inconsistent results even while they stay. Building the institutional memory and operational systems that make corporate giving compound over time is the final step in the practitioner’s guide.

Corporate relationships in the CRM

A corporate relationship involves multiple contacts at the same company — the CSR coordinator, the executive who championed the relationship internally, the HR manager who oversees the matching gift program, the employee volunteer coordinator — and each contact needs its own record, linked to the organizational record, with relationship history and next steps documented. The CRM record for a corporate prospect should include: all contacts at the company with their titles and relationship history, the door through which the relationship was opened, the current stage of cultivation, all previous gifts and proposals with amounts and dates, the company’s matching gift ratio, and portal information if applicable, the next scheduled touchpoint, and any notes about the company’s CSR priorities or decision-making cycle.

Helping corporate volunteers track their hours to claim volunteer grants

The volunteer grant is perhaps the most consistently unclaimed form of corporate support available to nonprofits, and the primary barrier is logistics — volunteers do not submit grant requests because the process feels complicated or because nobody has ever told them how to do it. At the close of every organized volunteer activity, the staff coordinator should collect participant names and hours, send each volunteer a written confirmation of their hours within a week, and include in that confirmation a brief explanation: “Many employers offer grants to nonprofits where their employees volunteer — typically $10 to $25 per hour. To find out, visit your employer’s HR portal or contact your HR department. We are happy to provide any additional documentation they require.” VolunteerHub (volunteerhub.com) and Galaxy Digital (galaxydigital.com) are dedicated volunteer management platforms that automate hour tracking and simplify the documentation process.

Promoting matching gifts so existing donors activate their employer’s programs

The three highest-impact places to promote matching gift eligibility are the donation acknowledgment letter, the website donate page, and the event-night announcement. The acknowledgment letter addition is a single sentence: “Your employer may match your gift to [Organization Name] — please visit your HR portal or contact your HR department to find out if a match is available.” Double the Donation provides an embeddable tool that allows donors to look up their employer’s matching program directly on the nonprofit’s website. The event-night announcement is thirty seconds from the podium. None of these require a new corporate relationship — they activate revenue already available through relationships the organization has already built.

The corporate giving calendar

A corporate giving calendar — built into the grants management system or CRM and visible to everyone on the development team — documents the key dates for every active corporate relationship: application deadlines, reporting due dates, renewal windows, CSR budget cycle timing, and scheduled cultivation touchpoints. The calendar should include not only grant deadlines but cultivation milestones — the quarterly check-in call, the mid-year impact update, and the invitation to the site visit. Corporate relationships erode without maintenance, and the calendar is the instrument that converts good intentions into consistent action.

Section 6 action step: Choose one operational gap from this section and close it this week. If your corporate relationships are not in the CRM, add the top five. If you are not tracking volunteer hours, build a simple collection process for the next event. If your acknowledgment letter does not mention matching gifts, add the sentence today.

Conclusion

Corporate giving is accessible to nonprofits of every size, and the path into it is more practical than it appears from the outside. The grant writer who understands the four doors, assesses which one is most accessible right now, researches the right companies through the right tools, understands the tax rules before signing anything, writes the proposal for the corporate reader rather than their own comfort, and builds the operational systems that make the program sustainable — that grant writer is building a corporate revenue stream that grows more reliable with each passing year.

The corporate relationships that produce the most durable revenue are not the ones built on a well-crafted proposal. They are the ones built on a genuine connection between the organization’s mission and the company’s own commitments — found through research, deepened through conversation, and sustained through consistent and professional follow-up.

Start with what you have. Activate the matching gift program in your existing donor base. Map the corporate connections in your board. Read one CSR report from a company that matters to your mission. The work of building a corporate giving program begins with the assets an organization already possesses, and those assets are almost always more substantial than they appear before the first inventory is taken.
