   Facts

   A Sec 133(6) notice is not an assessment, so options to correct your return may still be open. Depending on dates, you may revise the return or file an updated return with extra tax. Correcting before an assessment starts is usually cheaper.

   Provisions and law

   • Sec 133(6) (now Sec 252(1)(a))The officer can call for information useful for or relevant to any enquiry or proceeding
   • Sec 139(8A) (now Sec 263(6))An updated return (ITR-U) can be filed within 48 months from the end of the assessment year, with additional tax
   • Sec 140B (now Sec 267)Tax, interest and additional tax must be paid before an updated return is filed

   Analysis

   For AY 2026-27 you can still revise the return till 31 December 2026. For older years, an updated return under Sec 139(8A) (now Sec 263(6)) is possible within 48 months, with additional tax of 25% to 70% of tax and interest depending on the delay, unless a bar applies such as a pending assessment or reassessment, or a search. Check with a CA whether any bar applies before filing. Then tell the officer in your reply that the income has been offered, with the acknowledgement.
