Can I make my membership donation with installment payments?

When can I join?

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

How long is my membership valid?

Each paid-in-full membership donation provides voting membership for the current calendar year. The membership year runs from January 1 to December 31.

Are donations to Impact100 Oakland County tax deductible?

Yes. Impact100 Oakland County 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. Many members also join the 110% Club, donating $100 in addition to the membership donation in order to help cover administrative costs.

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

Yes. We gratefully accept employer matching gifts. These matches can be applied either to your membership or to the sponsorship of an additional member by matching your fully paid membership.

What role is there for me if I'm not ready to become 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.
