Can I make my membership donation with installment payments?

All installment payments are nonrefundable donations. Please email for more information about installment payments.

When can I join?

Anytime. We welcome new memberships throughout the year, but payment in full is due by December 31 in order to participate in the grant review process and vote on grants awarded the following May.

How long is my membership valid?

Each paid-in-full membership donation provides voting membership for the next calendar year. Ex: Members who join February through December 2021 will be eligible to vote in May 2022.

Are donations to Impact100 tax deductible?

Yes. Impact100 is a 501(c)(3) charitable organization. Contributions are tax-deductible for the year in which they were made.

I want to give more than the required membership donation. Do I get more than one vote?

Although additional gifts are always welcome, each Member is limited to one vote per person per year. But you can prepay your membership for subsequent years and/or sponsor others to join. If you would like to sponsor additional members, please email us at

If my employer or my spouse’s employer has a matching program, will you accept this donation?

Yes, you can double your impact. We gratefully accept employer matching gifts. Donations matching your membership contribution play an important role, as they are applied toward program and operating costs. Please submit a matching request for your donation to your or your spouse’s employer. Some employers will also provide matching donations for retirees.

How can I support Impact100 Greater Wausau without becoming a member?

We welcome “Friends of Impact 100” and are thrilled when an individual or a foundation wants to help us through monetary donations or in-kind service donations. Although they do not provide voting rights, these donations help cover program and operating expenses that are essential to accomplishing our mission.

Can I share a membership?

Yes!  The opportunity to share a membership between two women who each contribute $550 and share one vote for the recipient of the Impact grant is available.  As a shared member, you can attend ALL Impact100 events and serve on a committee, if interested.  However, only one of the two women sharing a membership may serve on a grants committee in a given cycle.

Please make sure to indicate who you are sharing your membership with when filling out the membership form.
