      <ExplanationTxt>We request abatement of any potential penalties based on reasonable cause and the actions taken to prevent the late filing of future returns. The volunteer board of directors comprises parents of students at California High School, none of who have experience with tax matters outside of filing personal income tax. We believe the organization has reasonable cause for late filing. They exercised ordinary business care and prudence with their knowledge and were not willfully neglecting their reporting obligations. Preventative steps to avoid late and/or incorrect filings will be taken, such as educating all new board members on all annual filing requirements, distributing filing due dates among all members, and adding the deadlines to the organizations bylaws and ongoing calendar. As part of their Parent Booster USA membership, we will send reminders regarding 990-series tax return filings and offer services to complete returns, including filing extensions on their behalf, when needed. Thank you for your consideration and help.</ExplanationTxt>
