A tax and compliance concept defining obligations, calculations, and controls used to meet legal and regulatory requirements. It governs tax measurement, reporting, filings, and compliance checks related to financial integrity and prohibited activity screening. It does not eliminate regulatory risk and requires accurate data, documented procedures, and timely remediation of findings. It supports lawful operation by ensuring obligations are met and by reducing exposure to penalties and enforcement actions. The concept is generally stable, though rules and enforcement expectations evolve over time.
