Support AU monthly through our Madison Society

You can support AU through our new Madison Society monthly giving program by pledging affordable installments to be deducted from your credit card or bank account.  This provides a dependable source of income for AU, while allowing us to save on administrative costs and effort. It also means that your membership will automatically renew! Enroll online today with your credit card, or e-mail membership@au.org for information about setting up automatic transfers from your bank account.

Give a Gift Subscription to Church & State Magazine

Giving someone a gift subscription to Church & State, Americans United's award-winning monthly journal, is a great way to support AU while sharing our work with others.

Ask Your Employer to Match Your Gift to AU

If your employer sponsors a corporate matching gifts program, your contribution to AU may be eligible to be doubled -- or even tripled! Find out more from your HR or personnel department, or e-mail membership@au.org for more information. If you have a form from your employer, complete your portion and mail it to AU's Development Department (address below) along with or after making your contribution, and we'll take care of the rest.

Make a Planned or Deferred Gift through AU's Jefferson Circle

Planned gifts are used to ensure the present and future vitality of Americans United. You can include AU as a beneficiary in your will, set up a charitable gift annuity, name AU as a beneficiary in a living trust, or make a gift of stock. All of these actions qualify you as a member of our Jefferson Circle planned giving society. Visit our planned giving pages through the link above, or e-mail us at membership@au.org with questions or to pledge a planned gift.


Americans United is a 501(c)(3) non-profit organization, and donations beyond the $18.00 value of a subscription to Church & State magazine and/or the $15.00 value of an optional premium book are deductible to the full extent of the law.

Please contact membership@au.org or (202) 466-3234 with questions about membership or contributions.

Thanks so much for your support of Americans United!
