122. (1) In computing the total income of an assessee, the deductions specified in
this Chapter shall be allowed from his gross total income, as per and subject
to the provisions of this Chapter.
(2) The aggregate amount of the deductions under this Chapter shall not, in any
case, exceed the gross total income of the assessee.
(3) If the deduction under section 133 or 135 or 137 or 138 or 141 or 142 or 143 is
admissible in computing the total income of an association of persons or a body of
individuals, no deduction under the same section shall be made in relation to the

Part C of this Chapter, where, in the case of an assessee, any amount of profits and
gains of an undertaking or unit or enterprise or eligible business is claimed and
allowed as a deduction under those provisions for any tax year,—
(a) deduction in respect of, and to the extent of, such profits and gains shall

In plain language
What Section 122 actually says
Section 122 is the gateway provision for all deductions under Chapter VIII of the Income-tax Act, 2025 (effective 1 April 2026). It does not give you any specific deduction by itself. Instead, it lays down the master rules that govern every deduction you claim — think of it as the rulebook that sits on top of Sections 123 to 154 (the sections that grant deductions like the old 80C, 80D, 80G, 80TTA, 80-IA, etc.). Section 122 is the direct successor to Section 80A of the Income-tax Act, 1961, but tightened with clearer language and stricter compliance conditions.
The core rules it establishes
- Deductions come out of "gross total income". Under sub-section (1), Chapter VIII deductions are allowed "from the gross total income" — the income figure computed under all the ordinary provisions of the Act before any Chapter VIII deduction is applied.
- Deductions can never exceed gross total income. Sub-section (2) is the single most important rule: your total Chapter VIII deductions cannot push your income below zero. You can wipe your taxable income down to nil, but you cannot create a loss or refund out of deductions.
- Definition of gross total income. Sub-section (10) defines "gross total income" as the total income computed under the Act before making any Chapter VIII deduction. This is the base figure for every percentage-based cap (like the qualifying limits under the donation and income-based deductions).
- No double deduction. The same amount of profit or expenditure cannot be claimed under two different sections, nor claimed again in another tax year.
Who it applies to
Section 122 applies to every assessee who claims any Chapter VIII deduction — salaried individuals, pensioners, professionals, proprietors, firms, LLPs, companies, AOPs and BOIs. If you are claiming a deduction that used to fall under Chapter VI-A (the "80-series") of the old law, it now lives in Chapter VIII and is policed by Section 122.
Key conditions and limits you must respect
- File your return on time. For the profit-linked business deductions in Part C of Chapter VIII (the old 80-IA/80-IB/80-IE type incentives), sub-sections (4) and (5) say the deduction is completely denied if you file a belated return or forget to claim it in the return. Timely filing under the due-date section is a hard precondition.
- Claim it in the return. A deduction not claimed in the return of income is lost — the assessing officer is not obliged to grant an unclaimed deduction.
- AOP/BOI members cannot double-dip. Sub-section (3) says if certain deductions are allowed to an Association of Persons or Body of Individuals, the individual member cannot claim the same deduction again on their share of that income.
- Inter-unit transfers at market value. Sub-sections (6)–(7) require that when goods or services move between an eligible unit and another business of the same assessee, the transfer must be at fair market value, so profits of a tax-holiday unit cannot be artificially inflated.
How it interacts with other sections
Section 122 works hand-in-hand with the deduction-granting sections. Each specific deduction (medical insurance, donations, savings interest, housing loan interest deductions, etc.) has its own conditions — but all of them are subject to the ceiling and definitions in Section 122. So even if two separate sections would together give you deductions of ₹6 lakh, but your gross total income is only ₹5 lakh, Section 122(2) caps the allowable deduction at ₹5 lakh.
Practical implications for a normal taxpayer
- Your tax planning ceiling is your income — chasing deductions bigger than your income is pointless.
- The old vs new regime matters: most Chapter VIII deductions are only usable if you opt for the old-style regime. Under the default new regime, the vast majority of these deductions are not available, so Section 122 becomes relevant mainly when you consciously opt out.
- Always file before the due date if you are claiming any profit-linked business deduction — a late return can silently destroy a large claim.
- Keep proofs and documentation: since claims must be made in the return and cannot be double-counted, mismatches invite disallowance.
💡 Example
Worked example 1 — the ceiling rule (Section 122(2)). Ravi, a freelance designer under the old regime, has a gross total income of ₹4,80,000. He wants to claim ₹1,50,000 (life insurance and PF type savings), ₹50,000 (health insurance for himself and parents) and ₹4,00,000 as a donation deduction — a total of ₹6,00,000. Section 122(2) says deductions cannot exceed gross total income. So the maximum he can actually deduct is ₹4,80,000, bringing his taxable income to nil. The remaining ₹1,20,000 of potential deduction simply lapses — it cannot be carried forward and cannot create a loss or refund.
Worked example 2 — the timely-filing condition (Section 122(4)/(5)). Meena runs an eligible manufacturing undertaking with a profit-linked deduction of ₹8,00,000 for the year. Her eligible profit is ₹8,00,000, so she expected to pay almost no tax. But she filed her return two months after the due date. Because Section 122(5) denies profit-linked Part C deductions on a belated return, the entire ₹8,00,000 deduction is disallowed, and she ends up paying full tax on ₹8,00,000. A single missed deadline cost her the whole incentive.
A relatable story. Think of gross total income as the water in a bucket, and deductions as taps draining it. Section 122(2) says you can empty the bucket completely, but you can never drain more water than the bucket holds — the taps stop the moment the bucket is empty. And Section 122(5) is like a rule that says the taps only work if you show up on time; miss the deadline and the taps stay shut, no matter how much water was in the bucket.

Frequently asked questions
What is Section 122 of the Income-tax Act, 2025 about?
Section 122 is the general rule governing all deductions under Chapter VIII. It sets out how deductions are allowed from gross total income, caps them at your total income, defines gross total income, and imposes conditions like timely return filing and no double deduction.
Which old section does Section 122 replace?
Section 122 replaces Section 80A of the Income-tax Act, 1961. It carries forward the same core principles — deduction from gross total income and the aggregate ceiling — with clearer drafting and stricter compliance conditions.
Can deductions make my income negative and give me a refund?
No. Under Section 122(2), the aggregate of Chapter VIII deductions can reduce your gross total income to nil but never below zero. Excess deductions simply lapse and cannot create a loss, be carried forward, or generate a refund.
What happens if I file my return late?
For profit-linked business deductions under Part C of Chapter VIII, Section 122(5) denies the deduction entirely if the return is filed after the due date or if the deduction is not claimed in the return. So timely filing is essential for those claims.
Does Section 122 apply under the new tax regime?
Section 122 governs Chapter VIII deductions generally, but most of these deductions are not available under the default new regime. It becomes relevant mainly when you opt for the old-style regime that permits these deductions.
What does 'gross total income' mean under Section 122?
Per Section 122(10), gross total income is your total income computed under all provisions of the Act before applying any Chapter VIII deduction. It is the base figure used for the ceiling and for percentage-based deduction limits.
Can both an AOP and its members claim the same deduction?
No. Section 122(3) prevents a member of an Association of Persons or Body of Individuals from claiming a specified deduction on their share of income if that deduction has already been allowed to the AOP or BOI itself.
