Supreme Court: Your Old Assessments Can Be Reopened — Two November Rulings Every Taxpayer Should Know

Two Supreme Court rulings in the space of a fortnight have redrawn the line on one of the most feared letters in tax: the reassessment notice. In the first, the Court upheld a notice reopening assessments where a search had thrown up bogus purchases spread over two years. In the second, it allowed the department to reopen assessments from 2008-09 over a ₹255 crore share sale. If you have ever assumed that an old, completed assessment is safe forever, these two cases say otherwise — with one important qualification. For the other side of the coin, read our explainer on when reassessment is invalid because no Section 143(2) notice was issued.

Ruling 1: bogus purchases across two years can be added up

In Khyati Vishal Popat v. Income Tax Officer (2026 TAXSCAN (SC) 266), the Supreme Court upheld a reassessment notice issued under Section 148 of the Income-tax Act, 1961. The facts were straightforward and, for the taxpayer, uncomfortable: a search had found material showing bogus purchases and cash dealings by a proprietary concern, extending across financial years 2018-19 and 2019-20.

The department invoked Section 149(1A), which allows escaped income relating to the same event to be aggregated across multiple assessment years. The Gujarat High Court had already upheld the notice, and the Supreme Court agreed.

Here is the practical point: if the same set of bogus transactions spans more than one year, the department does not have to treat each year in isolation. It can aggregate the escaped income and reopen the assessments together.

Ruling 2: a ₹255 crore share sale from 2008-09 can still be reopened

The second ruling is the more dramatic one. In October 2026, a bench of Justices J. B. Pardiwala and K. Vinod Chandran upheld the reopening of the assessments of Chetan and Nitin Sabharwal — sons of former Chief Justice of India Y. K. Sabharwal — over shares sold for ₹255 crore and a subsequent property purchase on Delhi’s Sikandra Road.

The story, as reported: in 2007 the brothers and two other shareholders agreed to sell their shares in Pawan Impex and SVIIT Software Pvt Ltd to GYS Real Estate Pvt Ltd for ₹255 crore. When Chetan filed his return for 2008-09, he declared a loss of ₹90.37 lakh. His scrutiny assessment was completed accepting the declared income; his brother Nitin’s return was processed routinely under Section 143(1). In 2015, the assessing officer issued notices under Section 148 to reopen both assessments, saying a “substantial amount has escaped assessment” for assessment years 2008-09 and 2009-10.

The Court held the notices were based on “tangible material” — an investigative-unit report — and that the alleged overvaluation of the shares and the use of the proceeds to buy another asset could involve “a diversion of income, assessable to tax under the guise of sale proceeds”. The reopening stands. Note what the Court did not decide: it did not hold that tax is actually payable. Reopening an assessment and winning the assessment are two different things — the department still has to prove the income escaped.

When reopening is legal — and when it is not

Put the two November rulings next to the Supreme Court’s other recent reassessment decision — the 29 October 2026 ruling that reassessment is invalid without a Section 143(2) notice — and a clear picture emerges:

• Real material wins. A search report, an investigative-unit report, or documents showing bogus transactions is “tangible material”. With it, the department can reopen — even years later, even across several assessment years at once.
• Procedure still matters. The department must follow the statutory steps, including issuing the notice under Section 143(2) where required. Skip a mandatory step and the reassessment fails, however strong the suspicion.
• An old assessment is not a shield. The Sabharwal case shows that even a completed scrutiny assessment can be reopened if fresh material surfaces. The usual rule is that a scrutiny-completed assessment cannot be reopened after four years — but that protection falls away where the department has material showing escaped income.
• Aggregation is now confirmed. Where the same event spans multiple years, Section 149(1A) lets the department add the escaped income together instead of reopening each year separately.

Under the Income-tax Act, 2025, which applies from 1 April 2026, these reassessment provisions now sit in Sections 279 to 281 (earlier Sections 147 to 149 of the 1961 Act). The principles in these rulings carry forward — the new Act reorganised the numbering, not the test.

What to do if a Section 148 notice lands in your inbox

A reassessment notice is not a demand. It is the start of a process, and the first few steps decide how it ends. Do not ignore it — and do not panic either.

1. Check the basics first. Was the notice issued within the time limit? Was the mandatory Section 143(2) notice issued along with it? A defect here can end the proceedings at the threshold — this is exactly what the 29 October ruling turned on.
2. Read the “reasons recorded”. The department must record reasons for believing income escaped assessment, and share them with you. Vague suspicion is not enough; the reasons must point to material.
3. Gather the transaction records. In both November cases, the department’s material was the deciding factor. Your defence is your own paper trail: purchase invoices, bank statements, share valuation reports, sale agreements.
4. File the return in response, on time. A Section 148 notice requires you to file a return for the year in question. Missing that deadline hands the department an ex parte assessment — decided without hearing you.
5. Take professional help early. Reassessment is a technical proceeding where the first reply shapes everything after it. A chartered accountant or tax counsel should review the notice before you respond.

The bottom line

These rulings reward the department for having material and punish it for skipping procedure. For an honest taxpayer, the lesson is mundane but real: keep your transaction records, keep share valuations, and keep purchase invoices — years after the event, not just until the return is filed. The Sabharwal assessments were reopened seven years after the transactions. Records are cheap; reconstruction is not. And if you are unsure where you stand, work out your tax position on the income-tax calculator before you respond to any notice.

FAQs

Can the department reopen my assessment after it was already completed?
Yes, if it has tangible material showing income escaped assessment. A completed scrutiny assessment is not a permanent shield — the Sabharwal case reopened assessments from 2008-09 in 2015. But the department must still follow the procedure, including the Section 143(2) notice.

What is Section 149(1A) aggregation?
It lets the department add up escaped income from the same event across multiple assessment years when the material comes from a search. The Popat ruling confirms this: bogus purchases in 2018-19 and 2019-20 were treated as one event, not two separate ones.

Does a reopening notice mean I have to pay tax?
No. It means the department believes income escaped and wants to reassess. You get to reply, produce records, and contest the claim. Tax is payable only if the reassessment is completed against you — and you can appeal that order.

How long does the department have to reopen?
Under the 1961 Act, the normal limit was three years from the end of the relevant assessment year, extendable to ten years where the escaped income was ₹50 lakh or more. The Income-tax Act, 2025 carries the reassessment framework in Sections 279 to 281 — check the specific year’s position with your adviser, because the limit depends on the assessment year and the amount involved.

I received a 148 notice but never got a 143(2) notice. What should I do?
Raise it in your very first reply. The Supreme Court’s 29 October 2026 ruling held reassessment invalid without a Section 143(2) notice. Our detailed explainer on that ruling sets out the argument.
