Legal Reference
Sections 279-280 (reassessment), Section 281 (faceless scheme), ITA 2025 | Finance Act 2021 restructured reassessment — only information-based reopening allowed | Corresponds to Section 147-151 of ITA 1961

1. When Can Reassessment Be Initiated?

The AO can reassess only when they have specific, credible information (not mere suspicion) suggesting that income chargeable to tax has escaped assessment. Under ITA 2025, the AO cannot reassess based on a change of opinion from the original assessment — there must be new information in their possession.

2. Time Limits for Reassessment

SituationTime Limit
Normal reassessment (income below Rs 50 lakh threshold)3 years from end of assessment year
Escaped income likely exceeds Rs 50 lakh5 years from end of assessment year
Search cases (Section 247)6 years from the Tax Year in which search was conducted

3. Common Triggers for Reassessment

  • AIS/SFT mismatch with filed ITR (high-value property purchase not reflected in ITR)
  • Cash deposits in bank account not matching declared income
  • Foreign asset/foreign account not disclosed
  • Third-party information: sale of property, large purchases, NRI remittances
  • GST turnover much higher than income declared in ITR
  • TDS in Form 26AS not matched with ITR income

4. Procedure After Receiving a Reassessment Notice

  1. Verify the notice: check section under which issued, date, and AO name
  2. Check if notice is within the limitation period
  3. Review the specific information the AO has (must be mentioned in notice under Finance Act 2021 framework)
  4. File a show cause reply within the time given — provide documents, bank statements, explanation
  5. If not satisfied with AO order: file appeal to Commissioner (Appeals) within 30 days

5. Faceless Reassessment

All reassessment proceedings are faceless under Section 281 of ITA 2025 — notices, responses, hearings, and orders are all through the IT Portal. No physical visits to AO office are required. The system randomly assigns cases to AOs in different cities for objectivity.

Can the tax department reopen my return after many years?

Under Sections 279-280 of the Income Tax Act, 2025, the normal reassessment window is 3 years from the end of the assessment year. It extends to 5 years if the AO has credible information suggesting escaped income exceeds Rs 50 lakh. For search cases, the window is 6 years from the searched Tax Year. After these limits, reassessment is time-barred. Returns filed before 2022 are governed by the older provisions under ITA 1961.

Can the tax department reassess without any specific reason?

No. Under the Finance Act 2021 restructuring (incorporated in ITA 2025), the AO can initiate reassessment only based on specific information in their possession suggesting income has escaped assessment. A mere change of opinion from the original assessment, or a suspicion without evidence, is not sufficient grounds for reassessment. The notice must specify the information on which the reassessment is based.

The right form filed late and the wrong form filed on time cause the same trouble — file the right one on time.

Under Sections 279-280 of the Income Tax Act, 2025, the normal reassessment window is 3 years from the end of the assessment year. It extends to 5 years if the AO has credible information suggesting escaped income exceeds Rs 50 lakh. For search cases, the window is 6 years from the searched Tax Year. After these limits, reassessment is time-barred. Returns filed before 2022 are governed by the older provisions under ITA 1961.

No. Under the Finance Act 2021 restructuring (incorporated in ITA 2025), the AO can initiate reassessment only based on specific information in their possession suggesting income has escaped assessment. A mere change of opinion from the original assessment, or a suspicion without evidence, is not sufficient grounds for reassessment. The notice must specify the information on which the reassessment is based.

Common triggers for reassessment notices include: AIS data showing high-value transactions not reflected in ITR (large property purchase, significant cash deposits); TDS in Form 26AS not matched with income declared; GST turnover much higher than ITR income; undisclosed foreign assets; third-party information from banks, registrars, or stock brokers. The IT Department AI system cross-matches AIS data with ITR automatically and flags mismatches.

First verify the notice — check the section, date, and whether it is within the limitation period. Read the specific information the AO has cited. Prepare a factual, document-supported reply within the given time period. Provide bank statements, property documents, or any evidence that explains the information cited. If you need more time, request an extension. Never ignore a reassessment notice — failure to respond results in ex-parte assessment (the AO decides without your input).

Under Section 281 of ITA 2025, reassessment proceedings are conducted in a faceless manner — the entire process is electronic through the Income Tax Portal. Notices, responses, hearings (through video conference if needed), and final orders are all online. The case is randomly assigned to an AO who may be in a different city, eliminating personal contact and potential influence. This system was introduced by the Faceless Assessment Scheme and is now standard under ITA 2025.
