This charity was started as a family-run organization to raise money for refugee children. We have never started run or filed as a charity before so we didnt know that the filing had to be done electronically. We downloaded the return forms from IRS website filled out the forms and mailed the return on time. IRS received our submitted forms on May 14 2025. Upon returning from a vacation in Japan on August 27 2025 we had received a letter from IRS dated August 15 2025. The letter was from Ms. Crowell Department Manager DPO Code & Edit Numbering informing us that form 990-PF should have been filed electronically and that we had 10 days to do so. As noted above we didnt get home from Japan until August 27 so the 10 day deadline had already passed. We would like to request that the IRS will not charge our small family-run charity with any penalties given that we did indeed meet the filing deadline of May 15 2025 and because we did not know of the e-filing requirement.
