Assessment of Undisclosed Income after Search under Income-tax Act 2025

Updated 11 October 2026 · Fact-checked

When a search is initiated or a requisition is made, the Assessing Officer assesses the total undisclosed income of the block period under Section 292. Pending assessments for tax years in the block period abate. The undisclosed income is taxed at 60% under Section 192, plus any surcharge levied by a Central Act.

Understand Assessment of Undisclosed Income after Search

A search is meant to catch income that was never shown in the regular returns. Instead of fixing it year by year, the Act uses a special one-time assessment. The Assessing Officer assesses the total undisclosed income of the block period as a single block, under Section 292(1). The rule applies irrespective of any other provision of the Act, for searches initiated or requisitions made on or after the Act's commencement.

The next idea is abatement. If assessment, reassessment or recomputation proceedings for a tax year in the block period were pending on the date of search (or requisition), they abate on that date: Section 292(2)(a). Proceedings for which a notice is issued after the search and up to the date of the block assessment order under Section 294(1)(c) also abate on the date of that notice, but not for the tax year in which the last authorisation was executed or the requisition made: Section 292(2)(b). A pending reference under Section 166(1) or an order under Section 166(6) abates together with the proceeding: Section 292(3).

The special assessment covers only undisclosed income. The other income of the tax year in which the last authorisation for search is executed (or requisition made) is assessed separately under the regular provisions: Section 292(6). So one searched person can have two assessments for that year: block and regular.

The tax rate is flat. Under Section 192(1), total undisclosed income of the block period, determined under Section 294, is chargeable at 60%. Section 192(2) adds any surcharge levied by a Central Act. Under Section 292(7) this is charged as income of the block period, irrespective of the tax year or years to which it relates. Do not apply slab rates.

Safeguards matter too. If the block assessment is annulled in appeal or other legal proceedings, abated proceedings revive from the date the Principal Commissioner or Commissioner receives the annulment order. The revival ceases if the annulment is set aside: Section 292(5). If a person already has a block assessment pending and is searched again, the pending one is completed first, and the later one gets at least three months from the end of the month of completion: Section 292(4).

Key rules to remember

Scope of special assessment
Search initiated / requisition made → AO assesses total undisclosed income of the block period
Section 292(1). Applies irrespective of other provisions of the Act.
Rate of tax
Tax = 60% × total undisclosed income of block period + surcharge, if any
Section 192(1) and (2). Surcharge only if levied by a Central Act. No slab rates, no basic exemption.
Abatement of pending proceedings
Pending proceedings for tax years in block period abate on date of search / requisition
Section 292(2)(a). Later notices up to the order under Section 294(1)(c) abate on date of notice, except for the tax year of the last authorisation or requisition: Section 292(2)(b).
Regular income of search year
Income other than undisclosed income of the year of last authorisation / requisition is assessed separately
Section 292(6).
Revival on annulment
Annulment of block assessment → abated proceedings revive from date order received by PCIT/CIT
Section 292(5). Revival ceases if the annulment order is set aside.
Earlier pending block assessment
Complete pending assessment first; later one gets at least 3 months from end of month of completion
Section 292(4).

How to solve Assessment of Undisclosed Income after Search questions

Use this order for any question on assessment after search. It keeps the law and the working separate.

  1. 1Confirm the trigger: a search was initiated or a requisition made on or after commencement of the Act. This brings Section 292 into play.
  2. 2Identify the block period and the tax years in it. Note the tax year in which the last authorisation was executed or requisition made.
  3. 3Deal with abatement. List the pending proceedings on the date of search and say they abate under Section 292(2)(a). Check later notices under Section 292(2)(b).
  4. 4Separate undisclosed income from income already disclosed or assessed. Only undisclosed income goes into the block assessment.
  5. 5Total the undisclosed income of the whole block period without splitting by year. Apply 60% under Section 192(1) and add surcharge only if the question says one applies.
  6. 6Assess the regular income of the search year separately under Section 292(6), using normal rates.
  7. 7Add any special point asked: revival on annulment, second search, or safeguards. Write a clear conclusion.

Quickest way: Four-line block assessment check

When to use it: For MCQs and short numerical parts where you need the answer fast.

  1. Ask: is it undisclosed income of the block period? If yes, tax at 60% flat.
  2. Ignore which year the income relates to. It is charged as block period income.
  3. Pending assessments for years in the block period: abated. Say so in one line.
  4. Income of the search year that is not undisclosed: separate regular assessment, normal rates.

Common mistakes in Assessment of Undisclosed Income after Search

  • Applying slab rates or the basic exemption to undisclosed income

    Students treat it like ordinary income.

    Fix: Use the flat 60% of Section 192(1), plus surcharge only if levied by a Central Act.

  • Assessing undisclosed income year by year

    Habit from regular assessments.

    Fix: Section 292(7) charges it as income of the block period irrespective of the tax year to which it relates. Add it up and tax once.

  • Forgetting abatement of pending proceedings

    Focus stays on the rate and the computation.

    Fix: State that pending assessments, reassessments or recomputations for years in the block period abate on the date of search: Section 292(2)(a).

  • Putting all income of the search year into the block assessment

    Confusion between undisclosed income and total income.

    Fix: Only undisclosed income goes to the block. Other income of the search year is assessed separately: Section 292(6).

  • Saying abated proceedings are lost forever

    Students overlook the revival rule.

    Fix: If the block assessment is annulled, abated proceedings revive from the date the order is received by the Principal Commissioner or Commissioner: Section 292(5). Revival ceases if annulment is set aside.

  • Quoting penalty sections or rates from memory

    The topic heading mentions penalties.

    Fix: Section 292 and Section 192 deal with assessment and tax rate. For penalties, give the general principle and refer to the penalty provisions; do not state a rate or section you are unsure of.

Worked examples

Example 1

A search was initiated on 10 November 2026 on Rakesh Mehta. The Assessing Officer determines undisclosed income of ₹30,00,000 for the block period. No surcharge applies. Compute the tax on this income and name the sections.

Show the solution
  1. Trigger: search initiated, so the special assessment under Section 292(1) applies.
  2. Undisclosed income of the block period = ₹30,00,000. It is charged as block period income, irrespective of the year it relates to: Section 292(7).
  3. Rate under Section 192(1) = 60%.
  4. Tax = 60% × ₹30,00,000 = ₹18,00,000.
  5. Surcharge: none, as the question says none applies (Section 192(2) allows it only if a Central Act levies one).

Answer: Tax on the undisclosed income is ₹18,00,000 at 60% under Section 192(1).

Example 2

Sunita Traders had an assessment for a tax year in the block period pending when a search was initiated on 5 March 2027. Another reassessment notice for a different year in the block period was issued on 20 May 2027, before the block assessment order under Section 294(1)(c), and that year is not the year of the last authorisation. What happens to both proceedings? Is regular income of the search year assessed?

Show the solution
  1. The pending assessment: Section 292(2)(a) says proceedings pending on the date of search abate on that date, 5 March 2027.
  2. The later notice: Section 292(2)(b) covers notices issued between the date of search and the date of the order under Section 294(1)(c), for years other than the year of the last authorisation. It abates on the date of issue, 20 May 2027.
  3. Any related reference under Section 166(1) or order under Section 166(6) abates with these proceedings: Section 292(3).
  4. Regular income of the search year other than undisclosed income is assessed separately under the other provisions of the Act: Section 292(6).
  5. If the block assessment is later annulled in appeal, the abated proceedings revive from the date the Principal Commissioner or Commissioner receives the annulment order: Section 292(5).

Answer: Both proceedings abate, the first on 5 March 2027 and the second on 20 May 2027. Regular income of the search year is assessed separately. Abated proceedings revive if the block assessment is annulled.

Exam tips

  • Memorise the two numbers that are certain: 60% (Section 192) and the section for assessment (Section 292). Write them in every answer.
  • In a numerical, show the block total, the 60% working and any surcharge as separate lines. Add surcharge only if the question states it.
  • For a theory question, structure the answer as trigger, block period, abatement, tax rate, separate assessment of other income, safeguards.
  • Do not give a penalty rate or section unless it is supplied in the question; describe the principle in plain words instead.
  • Read case scenarios carefully for which year is the year of the last authorisation. It decides the abatement and separate assessment points.
