What is Section 148 Notice?
📅 20 March 2026   |   ⏰ 10:30 AM

Section 148 of the Income Tax Act empowers the Assessing Officer to issue a notice to a taxpayer when there is information indicating that income chargeable to tax has escaped assessment for a relevant assessment year. However, before issuing such notice, the officer must comply with the procedure laid down under Section 148A of the Income Tax Act, which includes conducting a preliminary inquiry and passing an order under section 148A(3). The notice issued requires the assessee to furnish a return of income within a period specified in the notice, not exceeding three months from the end of the month in which the notice is issued. Such notice can only be issued when the Assessing Officer possesses credible information suggesting escaped income. This information may originate from risk management strategies framed by the Central Board of Direct Taxes, audit objections, international information-sharing agreements under sections 90 or 90A, information obtained through schemes notified under section 135A, directions arising from court or tribunal orders, or findings from surveys conducted under section 133A.

In simple terms-A notice under Section 148 of the Income Tax Act is sent to reopen a previously filed income tax assessment. The department asks you to file or revise your return for that specific assessment year because they suspect unreported income. Usually, it comes after a prior notice under Section 148A(1) of the Income Tax Act, which gives you a chance to explain.
