Statutory text
Bare law
(1) Irrespective of anything contained in any other provisions of this Act, the total undisclosed income of the block period, determined under section 294 shall be chargeable to tax at the rate of 60%. (2) The tax chargeable under sub-section (1) shall be increased by a surcharge, if any, levied by any Central Act.
Introduction
The 60% rate applies to the total undisclosed income determined under Section 294, not automatically to every item assessed in a search case. Subsection (2) separately addresses any applicable surcharge.
Key takeaways
Tax base
The base is total undisclosed income of the block period determined under Section 294.
Rate and surcharge
The rate is 60%; tax is increased by any surcharge levied by a Central Act.
Tax on undisclosed block-period income
Subsection (1) charges total undisclosed income determined under Section 294 at 60%, irrespective of other provisions of the Act.
Surcharge
Subsection (2) increases that tax by a surcharge if one is levied by a Central Act.
Establish the block income before applying the rate
The 60% rate is attached to the total undisclosed income of the block period determined under Section 294. Identify that amount from the special assessment process before doing the rate calculation. A search, a book entry or a seized amount does not by itself establish that every rupee is the determined undisclosed tax base.
Sections 292–294 supply important context: the block procedure, computation and determination must be examined together. Keep ordinary disclosed income and the block-period determination separate rather than applying 60% indiscriminately to every amount connected with the taxpayer.
Base tax and additional components
Compute the Section 192(1) base tax as 60% of the qualifying determined amount. Section 192(2) then increases that tax by a surcharge, if any, levied by a Central Act. The rate and applicability of that surcharge require the relevant Central Act; Section 192 does not state a universal surcharge percentage.
Do not label a base-tax illustration as the final demand. Applicable additional levies, interest, penalties, credits and payments require their own legal and factual examination. This guide does not assume that every such component applies to every block assessment.
Step-by-step computation check
1. Identify the block period and the order determining the undisclosed income under Section 294.
2. Reconcile that determined amount to the computation under the special block provisions.
3. Multiply the qualifying base by 60%, then separately check any Central-Act surcharge and other applicable demand components.
4. Reconcile the resulting computation with credit, payment and assessment records, preserving the distinction from ordinary-year income.
Hypothetical base-tax calculation
Assume the total undisclosed income of the block period is determined under Section 294 at ₹10,00,000. The tax under Section 192(1) is ₹10,00,000 × 60% = ₹6,00,000. This is the base tax only. No surcharge, other levy, interest, penalty or credit is assumed in that figure; each applicable component must be established separately.
If a figure is only proposed in a notice and the determination is disputed, distinguish the proposed computation from the amount finally determined. The arithmetic does not settle the underlying classification or assessment dispute.

Step-by-step flow for applying Section 192
- 1
Is there a determination of total undisclosed income of the block period under Section 294?
- No: Section 192 does not apply.
- Yes: Go to the next step.
- 2
Identify the amount determined
Use the amount determined under Section 294, kept separate from ordinary disclosed income.
- 3
Apply the 60% rate
Under Section 192(1), the rate applies irrespective of anything in any other provision of the Act.
- 4
Is a surcharge levied by a Central Act?
Section 192 does not state the surcharge rate; it comes from the relevant Central Act.
- Yes: Increase the tax by that surcharge under Section 192(2).
- No: The tax under Section 192(1) is the base figure.
Practical checklist
Do
- Identify the block period and the undisclosed income determined under the special search assessment provisions.
- Compute the stated tax and surcharge on that undisclosed income separately from ordinary-year tax.
Avoid
- Apply an ordinary slab rate to block-period undisclosed income without checking section 192.
Illustrative example
Worked example: tax on a determined block income
Hypothetical facts (illustration only, not a real taxpayer): In a search case, the total undisclosed income of the block period is determined under Section 294 at ₹25,00,000. For illustration only, assume a surcharge of 10% applies under a Central Act; this rate is an assumption and is not stated in Section 192.
Base tax
₹25,00,000 × 60% = ₹15,00,000 under Section 192(1).
Surcharge (assumed rate)
₹15,00,000 × 10% = ₹1,50,000, using the assumed rate only.
Tax after surcharge
₹15,00,000 + ₹1,50,000 = ₹16,50,000.
Outcome
- The 60% rate applies to the amount determined under Section 294, not to every amount linked to the search.
- The actual surcharge, and any interest, penalty or credit, must be checked separately; none is fixed by Section 192.
