What is the procedure adopted for making the assessment under section 147 i.e. income escaping assessment?

The procedures adopted for making the assessment under section 147 are as follows:

For making an assessment under section 147, the Assessing Officer has to​ issue notice under section 148 to the taxpayer and has to give him an opportunity of being heard. The time-limit for issuance of notice under section 148​ is discussed in later FAQ.

If the Assessing Officer has reason to believe that any income chargeable to tax has escaped assessment for any assessment year, then he may assess or reassess such income and also any other income chargeable to tax which has escaped assessment and which comes to his notice subsequently in the course of the proceedings under section 147. He is also empowered to re-compute the loss or the depreciation allowance or any other allowance, as the case may be, for the assessment year concerned.

Items which are the subject matters of any appeal, reference or revision cannot be covered by the Assessing Officer under section ​147.​
