About TAN AO Code

TAN AO Code is a 4-part code required in the TAN application form (Form 49B). It identifies the Income Tax office (Assessing Officer) that will handle your TDS/TCS returns. The code consists of: Area Code (3 letters), AO Type (2 letters), Range Code (number), and AO Number (number).
Search your city above, identify the Ward/Circle that matches your business jurisdiction, and note the 4 components. Enter these in the respective fields of your TAN application on the NSDL portal.
If you know your TDS Ward/Circle/Range from previous filings, select that exact entry. If you're new — select the row that covers your district's TDS deductions or contact your nearest Income Tax office.
TAN AO Code is for Tax Deduction Account Number applications — used by entities deducting TDS. PAN AO Code is for PAN applications — used by individuals and businesses for their personal/business tax assessment.
Yes, the Income Tax department reorganises jurisdictions periodically. Data here is sourced from NSDL's official portal. When in doubt, verify with your local Income Tax office.
