#iGiveCatholic on GivingTuesday Registration

16pxSpacer

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.

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 to create a new account. 
  • 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 we were unable to locate your EIN before the migration, you will have to provide your EIN with verifying documentation to create a new account before you can start to register. We will import your donation history from the previous platform at a later date. 

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, click the grey "?" circle on the bottom right, email questions@igivecatholic.org or call (202) 335-7735.
