Gross Total Income (Section 80B(5))
Also written Gross total income
The total income computed under the Act before any Chapter VI-A deduction — arrived at by adding the five heads of income, clubbing any income the law attributes to the assessee, and setting off losses.
In plain language
Before an assessee can claim deductions for insurance premiums, NPS contributions or medical expenses, the Act first needs a starting number to deduct them from. That starting number is the Gross Total Income.
Section 80B(5) defines it precisely: total income computed under the Act, before any deduction under Chapter VI-A — the whole family of Section 80 deductions, from 80C through 80U.
How it works
Gross Total Income is built in three steps.
Step 1 — add the five heads of income. Salary, house property, business or profession, capital gains, and other sources.
Step 2 — club income of other persons, wherever the Act's clubbing provisions require it, so income legally attributed to the assessee is added in even though someone else earned it.
Step 3 — set off losses, both within a head and across heads, for the current year and any losses carried forward from earlier years, subject to the ordinary set-off rules.
What remains after all three steps is Gross Total Income. Only from this figure are Chapter VI-A deductions subtracted to reach Total Income, the actual base on which tax is finally computed.
A worked example
Illustrative figures. Mr Iyer has salary income of Rs 12,00,000, a short-term capital loss of Rs 1,00,000 set off against a long-term capital gain of Rs 3,00,000, and rental income of Rs 2,00,000 clubbed into his own income because it arises from an asset he transferred to his spouse without adequate consideration.
Salary Rs 12,00,000
Capital gains (3,00,000 - 1,00,000) Rs 2,00,000
Clubbed rental income Rs 2,00,000
------------
Gross Total Income Rs 16,00,000
He then claims Rs 1,50,000 under Section 80C and Rs 50,000 under Section 80CCD(1B). His Total Income — the figure tax is actually charged on — is Rs 16,00,000 − Rs 2,00,000 = Rs 14,00,000, not the Rs 16,00,000 Gross Total Income itself.
Why NISM asks about it
Chapter 7 (Concepts of Taxation), section 7.12, defines Gross Total Income under Section 80B(5) and sets out the three computation steps, immediately before Chapter VI-A deductions and Total Income in sections 7.10 and 7.13. Expect a question distinguishing Gross Total Income from Total Income, and a computation that requires all three steps before any deduction is applied.
Common exam traps
- Gross Total Income is before Chapter VI-A deductions; Total Income is after them. Confusing the two changes every downstream tax calculation.
- Clubbed income is part of Gross Total Income even though someone else physically received it — the Act attributes it to the assessee by law.
- Losses are set off before arriving at Gross Total Income, not after.
- "Gross Total Income" here is a defined term under Section 80B(5), distinct from Adjusted Gross Total Income, which is a separate, narrower figure used specifically for the Section 80G donation ceiling.
