When the Universal Account Number (UAN) and Permanent Account Number (PAN) don't align, it can lead to various complications, especially in financial transactions and tax-related matters. The UAN is linked to an individual's Employee Provident Fund (EPF) account, while the PAN is a unique identification number issued by the Income Tax Department. Discrepancies between the two may arise due to errors in data entry, name variations, or other administrative issues. Resolving this mismatch promptly is crucial to ensure seamless financial operations and compliance with regulatory requirements. It often involves updating records with relevant authorities through prescribed procedures to harmonize the information and avoid any potential legal or financial consequences.
