Mightycause is the next generation of fundraising online. The online fundraising platform can empower your goals, groups, gatherings and do-goodery. Donating and fundraising on Mightycause is safe, secure, and simple.

Our largest segment of users is certified charities, or nonprofits. Organizations can use Mightycause to raise funds for their organization, and donors will automatically receive a tax-deductible receipt.

Our database is automatically imported and updated regularly from the IRS’ database of approved 501(c)(3) nonprofits with public charity status in the United States. Our database is also comprised of some educational institutions, religious organizations, and fiscally sponsored groups through one of the prior approved organizations on Mightycause.

How do I claim my organization on Mightycause?

Most organizations that exist in the IRS database automatically have an Organization page created on Mightycause. To see if your organization’s page exists on our platform, try searching in the Search bar at the top of the website for your organization’s EIN number.

Adding an organization that doesn’t yet exist on Mightycause

Don’t worry if your organization is not yet listed on Mightycause. Almost every nonprofit organization is sent an IRS Letter of Determination verifying that your organization is a 501(c)(3) public charity. To create your page, complete the steps below, and if requested, follow up with your IRS documentation.

Get started as a admin for a certified charity on Mightycause

To claim your organization’s page on Mightycause, you must create a Mightycause user account. Every user that wishes to claim admin access to their page must follow these steps:

It can take 24–48 hours for our team to process your claim form. We take security seriously, and want to ensure we properly verify all users claiming access to your organization’s information. For this reason, anyone who wants to be added as an administrator to your organization page must follow these steps. You can have up to 10 organization administrators on your organization’s page.

  1. Login to mightycause.com/login
  2. Click your name in the top right-hand corner of the page
  3. Select your organization from the dropdown menu
  4. You should be accessing your page as an organization admin!

You’ll know you’re on your organization’s page because there will be two indicators: 1) If you’re logged in, you’ll see the Mightycause Manager on the left side of your page, and 2) beneath your photo gallery it will say, “An Organization Page of [your organization’s name]”.

Looking to access your fundraisers? Simply click your name in the top right-hand corner and click “Fundraising” from the dropdown menu. For more information on charitable fundraisers, check out this Guide article.

How do I remove an administrator?

Any administrator for an organization can request for any other administrator (or themselves) to be removed. Send that request to the support@mightycause.com and let us know who you should be removed and which organization you are with.

International Organizations, or Waiting on Your 501(c)(3) Status?

In order to be listed on, and receive donations through Mightycause, the Organization must be registered in the U.S. as a 501(c)(3) public charity. If you’re still waiting to receive your 501(c)3 status (hint: you haven’t yet received your letter of determination from the IRS), you can still use Mightycause! Here’s how:

Set up a fiscal sponsorship

If your organization is not located in the United States or is waiting to receive 501(c)(3) status, you might consider a fiscal sponsorship. Organizations that are overseas or awaiting 501(c)(3) status can reach out to an organization listed in the fiscal sponsorship directory to have them act as a fiscal agent to receive tax deductible contributions.

Set up a personal fundraiser

You can also use our personal (non-tax deductible) fundraising platform for your fundraising needs. Personal fundraising on Mightycause means the creator can raise money for anything, and donations go straight to their US-based bank account. Personal fundraisers can be used to raise money for things like: medical expenses, organizing a neighborhood cleanup, an adoption and more. Check out this blog for more information on how to fundraise for your nonprofit with personal fundraising.

Many of the same tools are available as with our nonprofit platform. The transaction rate is 7.9% + $0.30 per donation. You can create your personal fundraiser by clicking here: https://www.mightycause.com/start-fundraiser

Why is my organization listed as ‘Unverified’ on Mightycause?

Mightycause’s database is regularly updated from the IRS database of 501(c)(3) public charities. If your Organization’s status has changed, your pages may become unverified until the IRS re-lists your Organization as approved or until you provide us recent documentation from the IRS confirming you are still an approved 501(c)(3) public charity. To confirm your Organization’s nonprofit status or request documentation, call the IRS (toll-free) at 1–877–829–5500.
