Corporate Sponsorship for Nonprofits: Finding, Asking and the IRS Line

To get corporate sponsors for a nonprofit, start with businesses that already have a reason to be seen with you: local companies whose customers are your supporters, firms where your board members and donors work, and companies that already sponsor causes like yours. Approach them with a specific, costed proposal tied to an event or programme, offer a few clear sponsorship tiers, and keep the benefits to acknowledgment, not advertising. That last point is the one most sponsorship guides leave out. Under IRS rules, a payment where the sponsor receives only acknowledgment of its name, logo or products is a qualified sponsorship payment and not taxable income to you. A payment for advertising, endorsements or exclusive selling rights can be taxable as unrelated business income. This page covers where to find sponsors, how to ask, sample packages, and the exact line between acknowledgment and advertising.

Where sponsors come from

US companies gave $43.67 billion to charity in 2025, according to Giving USA 2026, a small share of total giving but concentrated where it matters to most nonprofits: local business support of local organizations. The likeliest sponsors are rarely the largest companies.

• Your own people. The employers of your board members, volunteers and donors. A board member’s introduction outperforms any cold approach. Ask each board member for three names.
• Businesses your supporters already use. A bank, a grocer, a dentist, a car dealership, a law or accounting firm whose customers overlap with your audience has a commercial reason to be associated with you.
• Companies that already sponsor. Read the sponsor lists of similar events in your area, and the annual reports of comparable organizations.
• Corporate foundations and giving programmes. Many larger companies give through a foundation, which files a public Form 990-PF listing every grant; how to find a nonprofit’s Form 990 shows where. Others run in-kind and grant programmes listed in companies that donate to nonprofits.
• Employee giving. Companies that match employee gifts are a separate route covered in matching gifts.

Sponsorship or advertising: the IRS line

Treasury Regulation section 1.513-4 defines a qualified sponsorship payment as one where the sponsor receives no substantial return benefit beyond the use or acknowledgment of its name, logo or product lines in connection with your activities. Those payments are not unrelated business income. The difference between acknowledgment and advertising is in the wording.

According to the regulation, advertising includes qualitative or comparative language, price information or other indications of savings or value, an endorsement, and an inducement to buy, sell or use the sponsor’s products. A single message that mixes acknowledgment with any of these is treated as advertising. Acknowledgment can include logos and established slogans, the sponsor’s locations, phone numbers and website, value-neutral descriptions of its product lines, and brand names.

Four further rules matter in practice:

• The 2% rule. Benefits to the sponsor, such as event tickets, a reception or a booth, are disregarded if their total fair market value is 2% or less of the payment. Above 2%, the whole value of the benefits is a return benefit, not just the excess. Only the part of the payment above that value is a qualified sponsorship payment, and if you cannot show what the benefits were worth, none of it qualifies.
• Exclusive sponsor versus exclusive provider. Being named as the event’s only sponsor is generally fine. Agreeing that only the sponsor’s products will be sold or used at the event is an exclusive provider arrangement and generally is a substantial return benefit.
• No payments tied to results. A payment that depends on attendance, ratings or exposure is not a qualified sponsorship payment. One that depends only on the event taking place is fine.
• Periodicals are different. Acknowledgments in regularly published newsletters or magazines, printed or online, not tied to a specific event, fall outside the sponsorship rule and are treated under the advertising rules. An event program is not a periodical.

A written sponsorship agreement does not cause a problem in itself; its terms are what count. The regulation also says the classification does not decide how the sponsor deducts the payment, as a business expense or a charitable contribution, which depends on its own facts, so do not promise a company either. Selling products or advertising directly raises separate questions, covered in can a nonprofit sell products.

Sponsorship package examples

Here is a package for a fictional gala, with the tax treatment of each tier. Price your tiers from what the event or programme actually costs and what local businesses can realistically pay, not from national examples.

Keep the benefits in each tier to things you can deliver every time, and write the recognition wording into the package so nobody improvises an endorsement on the night. If a sponsor wants advertising, such as a discount offer in your program, that portion can be sold as advertising and treated as such; keep it separate in the agreement and the books.

How to ask

1. Find the decision-maker. At a small business, the owner. At a larger one, the marketing or community relations lead. A warm introduction from someone the company knows is worth more than anything you write.
2. Lead with their audience, not your need. Who attends, reads or follows you, how many, and why that matters to this business.
3. Make one specific ask. A named tier, a price and a deadline, with the full package attached.
4. Follow up once, by phone. Most sponsorships are agreed in a conversation, not by email.
5. Put it in writing. A one-page agreement: payment, date, benefits, recognition wording, and what happens if the event is cancelled.
6. Deliver, then report. Send photos of their logo in use, attendance figures and a thank-you within a week. A sponsor who is thanked well renews; the thank-you letter examples include one for event support.

A short sponsorship request

Dear Ms Hall,

Riverside Reading Partners runs after-school reading programmes for 140 children in four local schools. On April 18 we hold our Spring Reading Gala at the Riverside Hotel, for about 220 local business owners, parents and teachers, many of whom bank in the neighbourhood.

I am writing to invite Riverside Bank to be the presenting sponsor, at $10,000. The gala would be presented in your name, your logo would appear on every invitation, sign and page of our website for the season, and your team would have ten seats. The full package is attached.

Your sponsorship would fund the programme at Eastside Elementary for a year. I will call on Thursday to answer any questions.

With thanks, Jo Alvarez, Executive Director

Pricing your tiers

Price from the bottom up, not from what a national charity charges. Start with what the event or programme costs and how much of it sponsorship needs to cover, then ask what a local business would pay to reach your audience: the cost of a comparable local advertisement or community event booth is a useful anchor. Keep the top tier rare, one presenting sponsor, so it is worth something, and make the lowest tier easy enough that a small business owner can say yes on the phone. Three to five tiers is enough; more than that becomes a menu nobody reads.

Mistakes that lose sponsors

• Asking too late. Many companies set community budgets a year ahead. Ask for next spring’s event in the autumn.
• Promising benefits you cannot track. If you cannot report how many people saw the logo, do not promise “exposure to 10,000”.
• Forgetting the sponsor after the event. Recognition in your annual report and a thank-you call do more for renewal than any benefit in the package.
• Letting a sponsor write the copy. Endorsements and offers creep in, and with them the tax problem above.

Researching a company before you ask

Before any sponsorship conversation, find out what the company already supports. Its website and press releases show its causes; its corporate foundation, if it has one, files a Form 990-PF listing every grant it made, with amounts and purposes.

Gratefully, an AI donor intelligence and stewardship platform built for nonprofits, can do part of that research inside its assistant, Grace: ask about a foundation or organization and it builds a profile from IRS 990 filings, through ProPublica, and a bounded web search, covering giving, assets, leadership and focus areas, with every fact cited. It also reads your own CRM, so it can tell you which of your donors and board members already have a connection to a company. It is free for one person. It is wrong for researching companies that give directly rather than through a foundation, since there is no 990 to read; for managing sponsorship benefits and deliverables, which it does not do; and for anyone who needs an issued SOC 2 Type II report, which the company expects in the fourth quarter of 2026.

How this page was put together

The tax rules are from Treasury Regulation section 1.513-4 and IRS Publication 598, Tax on Unrelated Business Income of Exempt Organizations, read on 13 October 2026. The corporate giving figure is from Giving USA 2026, as reported by the Lilly Family School of Philanthropy. The package, prices and letter are illustrative, for a fictional organization. This page explains general rules and is not tax advice; a sponsorship with significant advertising or exclusivity terms is worth a review by your accountant.
