Treasury Regulations Sec 301.6651-1(c)(1) defines reasonable by asking whether the taxpayer exercised ordinary business care and prudence. The Foundation exercised care and prudence in seeking a reputable firm knowledgeable about exempt organizations to calculate its quarterly estimates for tax period ending December 31, 2024. The firm was unable to reconcile the Foundation's accounts fully in order to calculate the necessary estimated tax payment for Q4 based on the annualization method. The underpayment was no fault of the foundation's and the firm is enhancing its procedures to improve its reconciliation process for future quarters. We believe that the underpayment was due to reasonable cause and in no way due to an intentional disregard for the rules, and respectfully request that no 2220 penalty be assessed. 990-PF Estimated Tax for 2024 19200 990-PF Extension for 2023 100 Foreign Tax Paid 40 40
