  • Reconcile original tax filings, payments, and amendment reports within the tax management software against actual state submissions, ensuring accuracy and addressing historical discrepancies.
  • Accurately complete standardized templates within workbooks for capturing all necessary amendment-related information.
  • Collaborate closely with accounting, legal, and compliance teams to ensure all amendment filings adhere to regulatory requirements and internal policies.
