      <ExplanationTxt>The organization timely prepared and submitted its Form 990-EZ for the applicable tax year; however the return was filed by paper submission. The organization was not aware of the IRS requirement to electronically file Form 990-EZ. The paper return was subsequently rejected. Upon receiving notice of the issue the organization took immediate corrective action by preparing and submitting the return electronically through an IRS-authorized e-file provider. The organization has made a good faith effort to comply with all filing requirements and has implemented procedures to ensure that all future returns will be filed electronically in accordance with IRS requirements. We respectfully request abatement of any penalties based on reasonable cause.</ExplanationTxt>
