Identifies the Deductor or Collector Uniquely

• TAN provides a unique identifier for every person or entity responsible for deducting or collecting tax at source under the Income Tax Act.
  
• It ensures that all TDS/TCS activities are directly linked to the correct legal entity, enhancing traceability and accountability.
  
• This prevents anonymous or untraceable tax deductions, promoting a transparent tax environment.
  

Tracks TDS/TCS Payments Across the System

• Every TDS or TCS payment made to the government must be accompanied by a valid TAN, allowing tax authorities to monitor the flow of tax revenues.
  
• The use of TAN in Challan 281, TDS returns, and Form 16/16A ensures that all transactions are logged and reviewed in the central tax system.
  

Enables Accurate Credit to Taxpayers

• TAN usage ensures that tax deducted is correctly reflected in the deductee’s Form 26AS.
  
• This allows taxpayers to verify and claim TDS/TCS credits in their returns transparently, reducing disputes and improving refund accuracy.
  
• A correctly quoted TAN is key to maintaining trust between deductors and deductees.
  

Supports Automated Compliance Monitoring

• The Income Tax Department uses TAN data to automatically identify non-filers, short deductors, and defaulters.
  
• Default notices, interest calculations, and penalties are issued based on data collected under each TAN.
  
• This system-driven approach makes enforcement objective and audit-proof.
  

Reduces Scope for Tax Evasion and Manipulation

• TAN ensures that all payments subject to tax deduction or collection are routed through official tax channels.
  
• It limits the possibility of off-record transactions, under-reporting, or non-deposit of deducted tax.
  

By tying every transaction to a legal identity, TAN reinforces transparency, fairness, and integrity in the taxation system.
