What is a PAN AO code?
Every PAN is attached to an Assessing Officer (AO) of the Income Tax Department – the officer who handles that taxpayer's returns, notices and assessments. The AO is identified by a four-part code that you must enter when applying for PAN in Form 49A, or when a company or LLP gets its PAN through SPICe+ or FiLLiP:
| Part | Meaning | Example |
|---|---|---|
| Area Code | City / region code of the Income Tax charge | DEL, MUM, KNP |
| AO Type | W = Ward (usually ITO), C = Circle (usually DCIT / ACIT) | W or C |
| Range Code | Number of the range the ward or circle belongs to | 32 |
| AO Number | Number of the officer within that range | 2 |
How the jurisdiction is decided
The AO depends on three things: where the registered office or principal place of business is (city, district, locality or PIN code), who the taxpayer is (company, or non-company such as an LLP, firm or individual), and often the first letters of the name and the income level. A new company usually falls under the ward meant for lower income, because it has no income history yet.
For example, Delhi company cases are allotted by the first letters of the company name, while Mumbai uses PIN code groups together with the name and income. Many other cities use the district or municipal wards.
How this tool works
We have loaded the Income Tax Department's AO code list (the list used for PAN applications) into our database. When you enter an address, we look up the PIN code with India Post to find the district and localities. Then we score every Assessing Officer of that area on locality / PIN code, entity type, name letters and income level. The best match is shown with the reasons, and the full jurisdiction text is available so you can check it yourself.
Why the correct AO code matters
A wrong AO code does not stop PAN allotment, but notices, refunds and assessments then go to an officer who does not have jurisdiction. Transferring the PAN later needs a separate request to the AO. Choosing the right code at incorporation avoids that work. Setting up a new business? We handle company registration and LLP registration with PAN and TAN included.
Frequently Asked Questions
Where do I enter the AO code while incorporating a company?
In SPICe+ Part B the PAN and TAN applications are part of the form; the AO code of the registered office is selected there. For an LLP it is part of FiLLiP. For other applicants it goes in Form 49A (PAN) on the NSDL / UTIITSL portal.
What is the difference between a Ward and a Circle?
A Ward is headed by an Income Tax Officer and usually covers smaller cases; a Circle is headed by a Deputy or Assistant Commissioner and covers larger cases. Where the list splits cases by income, a newly incorporated company normally falls in the lower-income ward.
Why does the result depend on the company name?
In many cities (Delhi, Mumbai, Bengaluru, Gurugram, Ahmedabad and others) company cases are divided between officers by the first letters of the name. Enter the name exactly as proposed, without 'M/s' or 'The'.
Can I change the AO later?
Yes. If the registered office moves or the jurisdiction was wrong, you can apply to the present AO for migration of PAN to the correct AO. It is simpler to select the right code at the start.
Does this tool give the TAN AO code too?
The tool gives the PAN AO code. The TAN is allotted by the TDS Assessing Officer of the city; our team can confirm the TAN AO code for your address on WhatsApp free of charge.
The AO code is matched automatically from the Income Tax Department's AO code list. Jurisdictions are revised from time to time and some wards have no published rules – confirm the code (for example with the Income Tax ‘Know your jurisdictional AO’ facility or our team) before filing.
