Section 148, 148A → Section 280, 281: Reassessment — income escaping assessment

The department can reopen a past year if it has information that income escaped tax. Since 1 September 2024 the window is 3 years, extendable to 5 years where escaped income is ₹50 lakh or more.

How reopening works now

  • The officer shares the information and issues a show-cause notice under 148A, giving you time (usually 7–30 days) to reply
  • After considering the reply, an order under 148A decides whether it is a fit case
  • Only then is a notice under 148 issued, asking you to file a return for that year
  • Assessment follows like scrutiny, with full opportunity of hearing

What a good 148A reply contains

  • Point-by-point explanation of each transaction in the information (often from AIS, SFT or bank data)
  • Documents: bank statements, purchase/sale deeds, gift deeds, loan confirmations
  • Legal objections: time limit, sanction, whether the information actually shows escapement
  • Request for personal hearing through video conference if needed

Budget 2026 change

An updated return (ITR-U) can now be filed even after a reassessment notice is issued, with an additional 10% tax — a way to settle genuine omissions without penalty on that income. Decide only after legal advice; it is an admission.

Worked example

Example

Example: A notice for AY 2022-23 cites a ₹38 lakh cash deposit. A 148A reply showing the cash came from recorded business sales, backed by GST returns and books, can close the matter before a 148 notice is issued.

Common mistakes

  • Missing the 148A reply window
  • Replying with a general denial without documents
  • Not checking whether the notice is beyond the time limit

Frequently asked questions

Under the rules applying from 1 September 2024, generally no — the outer limit is 5 years from the end of the assessment year, and only where escaped income is ₹50 lakh or more.
