Do you ever refund donations?
Under the IRS code, a charity is rarely if ever required to return a donation for any reason. That being said, occasionally donors give twice accidentally through our website. Our staff can usually tell when this has occurred given our internal controls. In the case of a duplicate donation, we are always willing to refund that transaction. In cases where we suspect a duplicate transaction, we will contact the donor and inquire about their intentions. Once we get confirmation from them (in writing) of the intended gift amount, then we can refund one of the donations and adjust our records.
