Support the Museum

The National Mustard Museum has entertained and informed thousands since 1992. There’s no admission fee to this temple to the King of Condiments, so the museum relies solely on the generous donations from supporters like you.

The National Mustard Museum is a 501(c)3 tax exempt organization (EIN #27-4810858). This means donations to the National Mustard Museum are tax deductible for the donors. Proceeds from sales of select museum-produced items such as The Art of Mustard book and the Please Pass the Mustard board game also directly benefit the nonprofit museum. However, while we strongly encourage you to also support the Museum Gift Shop (a separate business entity from the museum*), those online or in-store purchases are not tax deductible. Keep the mustard flowing with a tax-deductible donation today!

So interesting! I loved looking at all the mustard containers. The movie was awesome, too. Staff was very knowledgeable & friendly. HUGE thumbs up!”

  • Is the Mustard Museum really a nonprofit organization? Yes. The IRS has confirmed its status as a 501(c)3 charitable organization.
  • Are purchases at the Gift Shop or online store tax deductible? No. The nonprofit National Mustard Museum does not sell mustard. The separate for-profit “, LLC” is in the business of selling mustards.
  • Why is the nonprofit museum separate from the for-profit gift shop? Until February 2011, there was only the for-profit business, which included the gift shop, the museum and its collection. Operating a museum is expensive and there was no way the for-profit could continue to maintain the museum through selling jars of mustard. The new nonprofit incorporated as a Wisconsin not-for-profit corporation in February 2011 and applied for tax-exempt status with the IRS in April 2011 (see below).
  • How does the Mustard Museum use its donations? Donations are used for rent, utilities, acquisitions, maintenance, staffing, marketing & promotion, as well as capital improvements.
  • Who owns the the extensive collection of mustards and mustard memorabilia? No one “owns” the collection. As a 501(c)3 nonprofit organization, it is “owned” by the organization. Barry Levenson, founder of the museum, personally purchased the original items in the collection and donated them to the nonprofit when the organization attained 501(c)3 status. 
  • How can I support the Mustard Museum? Your donations are the best way to support the museum as all funds go toward the nonprofit museum and its ongoing operations, maintenance and acquisitions. Online donations can be made through the online store at, or contact us to arrange for your donation at 800-438-6878. Another way to support the museum is through donating your time by volunteering at the various events staged at the museum throughout the year. To be an event volunteer, contact Barry Levenson at
