Thank you for your interest in joining the 11th Annual #iGiveCatholic on GivingTuesday, the U.S. Catholic Church's Day of Giving.
Registration is open from August 18 through November 1, 2025 to any Catholic 501c3 organization in the United States or Puerto Rico.
**RETURNING ORGANIZATIONS: Please wait until after September 1 for the best and easiest registration experience. When prompted to login, enter the email address you used with GiveGab, then set your new password.
Mightycause is migrating over 6,000 organizations who have participated in #iGiveCatholic since 2018 and will not be finished until September 1.
Every organization account must have an EIN tax id associated with it.
- This rule applies even if your diocese collects donations on your behalf and distributes them locally after the giving day ends.
- If you are registering for the first time and do not have an existing account in Mightycause, be prepared to provide your EIN and verifying documentation. If you are a part of a larger organization (i.e. a ministry or a school under a parish), provide your parent organization's EIN, then select “This EIN belongs to my fiscal sponsor.”
- If you participated in #iGiveCatholic in the past but did not provide your EIN and we were unable to locate it before the migration, you will have to provide your EIN with verifying documentation during the registration process.
Thank you for your understanding and patience as we make this big step into a new and more advanced platform! We KNOW you're going to love using the expanded features once we all get settled in!
For technical assistance, email questions@igivecatholic.org or call (202) 335-7735.
