Received a Section 148 or 148A income tax notice? Learn how to challenge a reassessment notice, identify potential legal grounds, respond within the prescribed timelines, and understand the options available to prevent an invalid reassessment.
A Section 148A or Section 148 notice is alarming, but it is not an order. The department has only said that it wants to reopen a year you thought was closed, and the law gives you several chances to stop it. This guide explains when reassessment can be stopped, which route works at which stage, and what to do in the first seven days. It is a practical entry point into income tax reassessment litigation for businesses, professionals and individuals.
Sometimes, yes. Reassessment can be stopped if the Assessing Officer (AO) drops the case after your reply to the Section 148A(b) notice, or if the notice or order is invalid and a court sets it aside. It cannot be stopped just because you disagree with it. If the reopening is valid, the better goal is to limit the additions and keep your position protected through appeals.
A note on the law: this guide applies to assessment years up to 2025-26, which continue under the Income-tax Act, 1961. The Income-tax Act, 2025 applies from tax year 2026-27 and renumbers many sections, so confirm the section numbers for your year.
Many people receive only the Section 148 notice and think this is where the process starts. In fact, a valid Section 148 notice should be preceded by a Section 148A(b) notice and a 148A(d) order. If either is missing, that itself is a point to raise. For the first stage, read our guide on replying to a Section 148A notice.
The AO must give you the information that suggests income has escaped assessment and allow at least seven days, up to thirty days, to reply. A complete reply with documents can show that the income was already disclosed, that the transaction is not taxable or that the information is wrong. If the AO is convinced, the 148A(d) order says the case is not fit for reopening and no Section 148 notice follows.
The time limit under Section 149 is three years from the end of the relevant assessment year, extending to five years if escaped income is ₹50 lakh or more in the form of an asset, expenditure or entry. If the notice falls outside the permitted period, it is invalid. Always count the dates from the notice date, not from the date you read it.
A notice can be set aside if the required approval was missing or given without application of mind, if the AO skipped Section 148A, or if the 148A(d) order does not deal with your reply. These defects are visible from the documents, so ask for copies of the material and approvals as early as possible.
A writ petition under Article 226 is the route for jurisdictional and procedural defects, such as limitation, missing sanction or a notice to the wrong person. Courts usually do not decide factual disputes in a writ and may ask you to follow the reassessment and appeal route. Read writ versus appeal to see the difference.
No. A writ does not freeze the case on its own. The court may grant interim relief, for example by allowing the AO to continue but not to pass a final order without leave, or it may refuse interim relief altogether. Meanwhile, you should keep complying with deadlines, including filing your return and replying to later notices, so that your position is not weakened if the writ fails.
If the reopening is valid, a good strategy still helps.
For what can follow if you stay silent, read what happens if you do not respond to an income tax notice. For who should handle your case, see who handles income tax reassessment proceedings.
The best chance to stop reassessment is at the very first step, the Section 148A(b) reply, so treat that notice as the main event. If the notice is out of time, lacks sanction or breaks the Section 148A process, a writ may end the case early. If reassessment goes ahead, a prepared file, a narrow assessment and timely appeals still protect you.

No. If you do not reply, the AO can pass a 148A(d) order and issue a Section 148 notice based on the material available, and the assessment can proceed against you.
No. It is a show cause notice that asks for your reply before the AO decides whether to reopen. The reassessment order comes at the end of the process.
Yes, through a writ petition, but courts normally intervene only for jurisdiction, limitation, sanction or procedural defects, not for pure factual disputes.
Courts have held that a mere change of opinion on the same material is not a valid ground for reopening. The AO needs fresh information that suggests escaped income, and this is a point to raise in your reply.
Generally yes, within the time stated in the notice. Filing a return does not mean you accept the reopening and you can still challenge its validity.
