TAN + TDS with TAXAJ →What is AO Code for PAN Card? — Complete Explanation
AO Code (Assessing Officer Code) is a unique alphanumeric identifier assigned by the Income Tax Department of India. It determines which Income Tax Assessing Officer (AO) has jurisdiction over your tax matters. The AO Code is mandatory for PAN card application (Form 49A), TAN application (Form 49B), and is used in all tax-related communications, assessments, notices, and ITR filing. An incorrect AO Code causes delays or rejection of your PAN/TAN application.
The AO Code consists of 4 components: Area Code (3-letter city identifier), AO Type (taxpayer category), Range Code (ward/circle number), and AO Number (officer's unique number). Together these 4 elements uniquely identify the Income Tax ward, circle, or range responsible for your jurisdiction.
Area Code
3-letter geographic code for your city. DEL = Delhi, MUM = Mumbai, BNG = Bangalore, CHN = Chennai, KOL = Kolkata.
AO Type
W = Ward (individuals, small businesses). C = Circle (companies, HNIs). H = HUF. I = International Taxation (NRIs, foreign entities).
Range Code
Numeric code identifying the specific ward or circle within the jurisdiction. Based on your residential or office address within the city. Varies by locality.
AO Number
Unique numeric identifier assigned to each Assessing Officer by NSDL / Protean. The final component of the AO Code. Published on NSDL and UTIITSL portals.
