Disclaimer: Before implementing any tax-related practices, nonprofits are strongly advised to consult with a qualified tax professional. The following blog post provides a guide to assist in understanding best practices for acknowledging event attendees and donors and is not professional tax advice.
After the last guest has gone home and the tables are cleared, the real relationship-building begins. How your nonprofit follows up with attendees after an event says a lot about your organization, and a thoughtful thank you can be the difference between a one-time attendee and a loyal, long-term supporter.
In this post, we will cover best practices for thanking event attendees, when and how tax acknowledgment letters are required, what the IRS expects you to include, and several sample letters you can customize for your own events.
Why Post-Event Thank Yous Matter
Thanking attendees promptly is not just good manners. It reinforces their connection to your mission, acknowledges their financial contribution, and sets the stage for future engagement. Whether someone paid $25 for a dinner ticket or $500 for a VIP table, they deserve a personal, meaningful follow-up.
For nonprofits using EventSnap, automated confirmation emails and receipts go out at registration. But a formal acknowledgment letter after the event adds a layer of gratitude and professionalism that automated receipts simply cannot replace.
Are Event Ticket Purchases Tax Deductible?
This is one of the most common questions nonprofits receive after a fundraising event, and the answer is: it depends.
According to the IRS, when a donor pays more than the fair market value of goods or services received, only the amount in excess of fair market value is considered a charitable contribution. This is known as a quid pro quo contribution.
For example, if a ticket to your gala costs $150 but the fair market value of the dinner and entertainment provided is $60, the attendee may be able to deduct $90 as a charitable contribution.
IRS Requirements for Quid Pro Quo Contributions
If your nonprofit receives a quid pro quo contribution of more than $75, the IRS requires you to provide a written disclosure statement that:
- Informs the donor that the amount of the contribution that is deductible is limited to the excess of the payment over the value of the goods or services provided
- Provides a good faith estimate of the fair market value of the goods or services
Failing to provide this disclosure can result in penalties for your organization, so it is important to have a process in place before your event.
How to Determine Fair Market Value for Event Tickets
Fair market value is the price a willing buyer would pay a willing seller when neither is under any obligation to buy or sell. For event tickets, this typically means the cost of the food, beverages, entertainment, and any other tangible benefits your attendees receive.
Tips for Estimating Fair Market Value:
- Catering costs: Get an itemized cost per plate from your caterer. This is often the most straightforward component to document.
- Entertainment: If you hired a band, DJ, or performer, estimate the per-person value of that entertainment.
- Venue amenities: If attendees receive access to a premium venue, open bar, or other special experiences, factor those in.
- Exclude mission-driven value: The emotional or philanthropic value of supporting your cause does not count toward fair market value for IRS purposes.
- Document everything: Keep receipts and estimates on file in case of questions later.
Once you have your fair market value estimate, display it clearly on your event registration page, in your event program, and in your post-event acknowledgment letter. EventSnap makes it easy to include this information in your event setup so attendees see it before they register.
Where to Display Fair Market Value
Transparency builds trust with your donors. The IRS recommends providing the fair market value estimate at the time of the transaction, which means:
- On your registration/ticketing page before purchase
- In your event confirmation email
- In your printed event program or signage at the event
- In your post-event acknowledgment letter
The more visible you make this information, the easier it is for attendees to work with their accountant and the more confidence they will have in your organization.
IRS Requirements for Written Acknowledgment Letters
For any single contribution of $250 or more, the IRS requires a written acknowledgment from the nonprofit. This applies to the full ticket price paid, not just the deductible portion.
Your acknowledgment letter must include:
- The name of your organization
- The date of the contribution
- The amount of cash paid (or a description of non-cash donations)
- A statement of whether any goods or services were provided in exchange, and if so, a good faith estimate of their fair market value
If no goods or services were provided (for example, a donor made an additional cash gift at the event), the letter should state: “No goods or services were provided in exchange for this contribution.”

Beyond the Letter: Other Ways to Thank Event Attendees
A formal acknowledgment letter covers your legal bases, but there are plenty of other ways to make attendees feel genuinely valued:
- Personalized email within 24 hours: A brief, personal email from your executive director or event chair while the event is still fresh goes a long way.
- Social media shout-outs: Tag sponsors and highlight attendee participation on your organization’s social channels (with permission).
- Impact update: A few weeks after the event, send a follow-up sharing the total raised and what it will accomplish. Closing the loop reinforces why their attendance mattered.
- Save the date for next year: Let enthusiastic attendees be the first to know about your next event.
- Handwritten notes: For major donors or sponsors, a brief handwritten card adds a personal touch that stands out in a digital world.
