The Income Tax Department has enabled the online submission of Form ITR-B through the e-Proceeding tab on the official Income Tax e-filing portal.
This move comes as part of the department's continued push towards faceless, paperless, and transparent tax administration. Section 158BC pertains to the assessment of undisclosed income discovered during search and seizure actions carried out under Section 132 or 132A. Form ITR-B is specifically required for filing returns of income in block assessment cases, which generally cover undisclosed income for a block period of ten years.
