Income Tax Office in Kolkata: How to Find Your Assessing Officer, Jurisdiction and Where to Raise Grievances
Every PAN in Kolkata is assigned to a jurisdictional assessing officer (AO) in a ward or circle under the Principal Chief Commissioner of Income Tax, West Bengal and Sikkim, whose headquarters is Aayakar Bhawan in Kolkata. You can see your AO’s ward, circle, address and email by logging in to the e-filing portal and checking your jurisdictional AO details. Most assessments, appeals and penalties are now faceless, so you rarely meet the officer, but the jurisdictional AO still handles PAN migration, rectifications in some cases, and several applications. This guide explains how to find yours and where to take common problems.
How to find your assessing officer
- Log in to the income tax e-filing portal.
- Open your profile and look for the jurisdictional AO details.
- Note the area code, AO type, range code and AO number, the ward or circle, and the office address.
Without logging in, the “Know your AO” service on the portal shows the details after PAN and mobile OTP.
What faceless assessment changed
- Scrutiny assessments, appeals to the Commissioner (Appeals) and penalties are handled by national faceless centres. Notices come by email and on the portal, and you reply online.
- You cannot meet the assessing officer during faceless proceedings, though you can ask for a personal hearing by video conference.
- The jurisdictional AO still deals with some work, such as survey and search cases, certain applications and some post-assessment matters.
Where to take common problems
| Problem | Where to go |
|---|---|
| Refund not received | Check refund status; raise a grievance on e-Nivaran in the portal |
| Wrong demand | Respond to the outstanding demand online; seek rectification |
| TDS mismatch | Ask the deductor to revise the TDS return; TRACES handles statements |
| PAN in wrong jurisdiction (for example, moved from Kolkata) | Request PAN migration through the jurisdictional AO |
| Lower deduction certificate | Apply online; the jurisdictional TDS officer decides |
| Notice from an assessing officer | Reply online by the due date; seek adjournment if needed |
Grievances
Use e-Nivaran on the e-filing portal for refund delays, rectification and processing errors. If it is not resolved, escalate within the system, and for persistent issues write to the jurisdictional Principal Commissioner. Keep acknowledgement numbers.
Notices: don’t ignore them
Many Kolkata taxpayers miss notices because the email on the portal is outdated. Update your email and mobile, and check the e-proceedings tab every few weeks. Typical notices relate to AIS mismatches, high-value transactions, property sales and unreported interest.
