I have setup a golf tournament event. It is using a financial type where I have set deductible=no (we want to issue tax receipts to registrants after the event when we know the true deductible amount). So how is Civi still sending a tax receipt when people register? Note: it isn't happening every time someone registers, but it did happen when it never should have.
I looked at the event setup and can't see anything that would trigger a tax receipt being attached to the automated registration email.
Any ideas? If the fintype is set to not issue receipts, I don't understand why a receipt would be issued for any reason.
