Who is an Assessing Officer? How to Find Out an Assessing Officer?
An assessing officer is assigned to every taxpayer depending on the PAN number and the address details of the PAN number. The assessing officer assigned to the taxpayer is called a jurisdictional AO.

It is important for taxpayers to know their AO and to get their PAN migrated to the proper jurisdictional AO if they change their address.
Who is an Assessing Officer?
An Assessing Officer (AO) is an Income Tax Department officer responsible for ensuring the regularity of ITR filed by the taxpayers in his/her jurisdiction. The AO has the authority to examine the returns, ask for supporting documents, recompute the taxable income, and issue assessment orders and tax demands. The AO also handles any taxpayer concerns or requests, such as rectifying returns and issuing refunds.

The AO is responsible for ensuring that the taxpayer pays the correct amount of tax according to the law and the facts of the case. The AO also has the power to ask for books of accounts, documents, and other evidence from the taxpayer to verify the accuracy and completeness of the return of income filed by him or her.
