Gross Total Income and Deductions Framework under Income-tax Act, 2025

Updated 10 October 2026 · Fact-checked

Gross total income is the total income computed under the Act before any deduction under the deductions Chapter. You subtract the allowed deductions from it to get total income. The aggregate of these deductions cannot exceed gross total income, so total income never falls below zero because of them (section 122).

Understand Gross Total Income and Deductions Framework

Start with the flow of a computation. You compute income under each head, apply clubbing, then set off and carry forward losses. The result is gross total income (GTI). Section 122(10) defines it as the total income computed as per the Act, before making deduction under the deductions Chapter.

Next, you subtract the deductions allowed under that Chapter. What is left is total income, on which tax is computed. So the order is fixed: heads of income, then GTI, then deductions, then total income.

Section 122 sets the general rules. Deductions are allowed from GTI as per and subject to the provisions of the Chapter. Their aggregate cannot exceed GTI. This is a ceiling on the total claim, not a ceiling on each deduction. Each deduction also has its own limits in its own section.

There are further conditions. For the profit-linked deductions in Part C, you cannot claim the same profits twice under another provision. The deduction cannot exceed the profits of that undertaking, unit, enterprise or eligible business. You also lose the Part C deduction if you do not file the return by the due date under section 263(1), or do not claim the deduction in that return.

Some taxpayers have restricted deductions. A non-resident Indian whose GTI has only investment income or long-term capital gains gets no Chapter VIII deduction (section 213). Companies that opt for the concessional rates in sections 199, 200 or 201 must compute income without most deductions.

Key rules to remember

Total income
Total income = Gross total income − Deductions allowed under the deductions Chapter
Tax is computed on total income. Check each deduction's own conditions first.
Meaning of gross total income
GTI = total income computed as per the Act, before deduction under the Chapter (s.122(10))
It comes after set off and carry forward of losses and after clubbing.
Overall ceiling
Aggregate of deductions ≤ Gross total income (s.122(2))
Apply it to the sum of all deductions claimed, after each one is limited by its own section.
Part C profit-linked deduction limit
Deduction ≤ profits and gains of the undertaking, unit, enterprise or eligible business (s.122(4)(b))
The same profits cannot be deducted again under another provision for that tax year.
Return condition for Part C
Return furnished by the due date under s.263(1) AND deduction claimed in that return
If either is missed, the Part C deduction is not allowed (s.122(5)).
Transfer at market value
Profits recomputed as if transfer was at market value (s.122(6))
Applies if the recorded price for goods or services moved between the eligible unit and another business differs from market value.
Deduction base for specified income
Income of that nature as computed before any Chapter deduction (s.122(9))
Use this figure as the income derived when computing a Part C deduction.

How to solve Gross Total Income and Deductions Framework questions

Use this order for any question that asks for total income or for the effect of a deduction.

  1. 1Compute income under each head, with its own deductions and exemptions.
  2. 2Apply clubbing, then set off and carry forward of losses, to reach gross total income.
  3. 3List each deduction claimed and check its own section's conditions, such as eligibility, limit and residential status.
  4. 4For Part C deductions, check the return was filed by the due date under section 263(1) and the claim was made in it.
  5. 5Limit each deduction to its own cap, and to the profits of the unit for profit-linked deductions.
  6. 6Add the allowed deductions and cap the total at gross total income.
  7. 7Subtract to get total income, then round as the question requires and compute tax.

Quickest way: Three-check shortcut

When to use it: Use it in MCQs and short numerical questions where income under the heads is already given.

  1. Check what is being asked: GTI or total income.
  2. Cap each deduction at its own limit.
  3. Compare the sum of deductions with GTI and take the lower.
  4. Then check special cases: NRI with only investment income or long-term capital gains, or a company under section 199, 200 or 201 where deductions are barred.

Common mistakes in Gross Total Income and Deductions Framework

  • Deducting Chapter deductions before set off of losses

    Students treat deductions as part of computing each head.

    Fix: Remember GTI is before the Chapter deductions but after set off and carry forward of losses. Deductions come last.

  • Letting deductions exceed GTI and showing negative total income

    Each deduction is checked alone, but the total is not.

    Fix: Always apply section 122(2): the aggregate of deductions cannot exceed GTI.

  • Allowing a Part C deduction when the return was filed late

    Students focus on the profits and forget the condition.

    Fix: Under section 122(5), the return must be furnished by the due date under section 263(1) and the claim made in it.

  • Claiming the same profits under two provisions

    Both provisions seem to apply to an eligible unit.

    Fix: Under section 122(4)(a), once profits are deducted under Part C, no other provision allows a deduction on that profit for that tax year.

  • Giving deductions to a company that opted for a concessional rate

    Students forget the option changes the computation.

    Fix: Sections 199, 200 and 201 require income to be computed without most deductions. Section 200 and 201 permit only specified exceptions, such as section 146 and 148 in Chapter VIII.

  • Giving an NRI deductions on investment income or long-term capital gains

    Students apply the general rule to all taxpayers.

    Fix: Under section 213(2), reduce GTI by that income, and allow deductions only on the rest. If the GTI is only that income, allow none.

Worked examples

Example 1

Mr. Raman Iyer, a resident individual, has gross total income of ₹4,00,000. He is eligible for deductions totalling ₹4,60,000 under the deductions Chapter, each within its own limit. Find his total income.

Show the solution
  1. Gross total income = ₹4,00,000.
  2. Deductions claimed, each within its own limit = ₹4,60,000.
  3. Section 122(2): aggregate deductions cannot exceed GTI, so allowed deductions = ₹4,00,000.
  4. Total income = ₹4,00,000 − ₹4,00,000 = ₹0.

Answer: Total income is ₹0. The excess deduction of ₹60,000 is not allowed and cannot create a negative total income.

Example 2

Meera Textiles Ltd., a domestic company, has salary-free business income of ₹10,00,000 and no other income. Of this, ₹3,00,000 is profit of an eligible unit. It claims a Part C deduction of ₹3,50,000 on that unit, and ₹1,00,000 under another deduction within its limit. The return was filed by the due date under section 263(1) and the Part C claim was made in it. The company has not opted under section 199, 200 or 201. Find total income.

Show the solution
  1. GTI = ₹10,00,000.
  2. Part C deduction cannot exceed the profits of the unit (section 122(4)(b)): allowed = ₹3,00,000, not ₹3,50,000.
  3. The return condition in section 122(5) is met, so the deduction stands.
  4. The ₹1,00,000 other deduction is within its limit and is not on the same unit profits.
  5. Total deductions = ₹3,00,000 + ₹1,00,000 = ₹4,00,000, which is below GTI, so the section 122(2) cap does not bite.
  6. Total income = ₹10,00,000 − ₹4,00,000 = ₹6,00,000.

Answer: Total income is ₹6,00,000.

Exam tips

  • MCQs often test one rule: aggregate deductions cannot exceed GTI, or the return condition under section 122(5). Read the options for these traps.
  • In written answers, show GTI as a separate line, then each deduction with its section, then total income. Step marks follow this layout.
  • Always state the condition you checked, such as the due date under section 263(1), even if it is met.
  • If a company opts for section 199, 200 or 201, say that income is computed without the specified deductions before you compute tax at the concessional rate.
  • Use the Income-tax Act, 2025 terms: tax year, not assessment year.

Gross Total Income and Deductions Framework: frequently asked questions

What is the difference between gross total income and total income?

Gross total income is income after clubbing and set off of losses, before Chapter deductions. Total income is what remains after the allowed deductions are subtracted. Tax is computed on total income.

Can deductions reduce total income below zero?

No. Section 122(2) says the aggregate of the deductions cannot exceed gross total income. So the lowest total income they can produce is zero.

Do I lose a Part C deduction if I file my return late?

Yes. Section 122(5) denies Part C deductions if you do not furnish the return by the due date under section 263(1), or do not claim the deduction in that return.

Can a company choosing a concessional tax rate claim deductions?

Mostly no. Sections 199, 200 and 201 require income to be computed without the specified deductions. Sections 200 and 201 allow only listed exceptions, such as sections 146 and 148 in Chapter VIII.
