Deductibility and the entity

Most chambers are not charities

A chamber of commerce is typically organised as a 501(c)(6) business league. That is a tax-exempt organization, which is where the confusion starts — exempt from tax itself is not the same as able to receive deductible charitable contributions.

Payments to a business league are generally not charitable contributions. A member may be able to treat a purchase or a sponsorship as an ordinary business expense, which is a genuinely different basis with different conditions, and it is not the chamber's place to advise on it.

The affiliated foundation changes the answer

Many chambers operate a separate 501(c)(3) foundation for scholarships, education, leadership programmes and community work. Where the foundation runs the auction, the charitable answer applies — subject to the usual rule that a bidder may generally deduct only what they pay above fair market value.

So settle one question before anything else: which entity is running this auction, and which one receives the money? The answer determines what you may say, what the receipt says, and where the funds may be spent.

• If the purpose is charitable — scholarships, education, community programmes — the foundation is usually the right home and the better answer for members
• If the purpose is chamber operations, the chamber runs it and the language changes
• Do not route money through the foundation for a purpose the foundation cannot support just to improve the sentence

What to put on the page

One plain, accurate sentence naming the receiving entity, and a statement of fair market value on each item where a charitable entity is receiving.

What not to do: copy the language from a charity auction template. "Your donation is tax deductible" on a chamber's own auction page is the specific error this page exists to prevent, and members' accountants will notice it before members do.

Say less rather than more

Members will ask, and the right answer is that the chamber cannot advise on their tax position — here is the receiving entity, here is the fair market value, please speak to your accountant.

That is not unhelpful. In a room of business owners it reads as an organization that knows the boundary of its own competence, which is a better impression than a confident wrong answer.

Sponsorship, and what a sponsor receives

Where a sponsor receives substantial benefits — advertising, a table, promotional value — the treatment differs from a pure gift, and the distinction between qualified sponsorship and advertising is a real one with consequences for the organization as well as the payer.

Get the sponsorship structure reviewed once by your own adviser and reuse it. Chambers rebuild sponsorship packages annually and rarely have them looked at.

And keep the two entities' money separate

Where both a chamber and a foundation exist, the accounts, the receipts and the spending have to stay distinct — including the auction's costs. It is the sort of thing that is straightforward to do prospectively and awkward to unpick afterwards.

General information, not tax or legal advice for your chamber. Whether a payment is deductible, and on what basis, depends on your entity's status and what the payer received — check with your own adviser before telling members anything about it.
