Every tax return begins with a story — and at the center of that story sits your Gross Total Income (GTI). Before you think about deductions, investments, or exemptions, the law asks one simple question: how much did you earn in total?
That figure — untouched & unfiltered — is your Gross Total Income.
It is, quite literally, the sum of everything you’ve earned under the five heads defined by the Income Tax Act, 1961. Whether you draw a salary, rent out property, run a small business, or earn interest from deposits — everything counts.
Legal Basis and Relevance
The meaning of GTI appears in Section 80B(5). It might sound technical, but the logic is simple: before applying any deduction under Chapter VI-A, the law first totals up every rupee of income.
This is why a correct GTI figure is essential — it affects your tax bracket, refund eligibility, and even the success of your deductions.
How It’s Calculated — The Five Income Heads
Gross Total Income is calculated foremost by adding your income under all five heads of income.
- Salary: Basic pay, allowances, commissions, and pension — the regular paycheck."
- House Property: Rent received, or the notional rent if more than one property is owned.
- Business or Profession: Income from self-employment, freelancing, or trade.
- Capital Gains: Profits from selling assets like mutual funds, land, or gold.
- Other Sources: Interest, gifts, dividends, or winnings from games & lotteries.
When these five are added together, you get a clear picture — your Gross Total Income, the income before any tax planning begins.
A Quick Example to See It in Action
Take Rohan, who works in Bengaluru:
- Salary: ₹8 lakh
- Rent from property: ₹1.2 lakh
- Small trading profit: ₹80 thousand
- Capital gains: ₹1.5 lakh
- Bank interest: ₹40 thousand
So, his Gross Total Income = ₹12 lakh.
This ₹12 lakh is what the department looks at before deductions like 80C or 80D are subtracted.
It’s his “unfiltered” income snapshot for the financial year.

What’s Included
Your GTI covers every taxable stream of income:
- Salary or pension
- Rent & property yield
- Business or professional profits
- Investment gains
- Interest and miscellaneous receipts
In short, it’s the total income received from all sources before exemptions.
And What’s Not
Certain incomes are excluded from GTI because they’re fully exempt.
For instance, agricultural income under Section 10(1), income of charitable institutions, specific allowances for diplomats, or dividend income within limits.
These do not form part of your GTI, which keeps your tax base fair.
Difference Between Gross Total Income & Total Income
This one confuses many.
Your Gross Total Income is like the total marks you scored before grace points, while Total Income is what remains after exemptions & deductions.
So, if GTI = ₹12 lakh & you invest ₹1.5 lakh under Section 80C plus pay ₹25 thousand as medical insurance (80D), your taxable income becomes ₹10.25 lakh.
➡️ GTI → before deductions
➡️ Total Income → after deductions
Deductions You Can Claim from GTI
The Income Tax Act allows several reliefs under Chapter VI-A:
- Section 80C: Up to ₹1.5 lakh for PF, PPF, ELSS, or life insurance.
- Section 80D: Health-insurance premium for self & family.
- Section 80G: Donations to eligible charities.
- Section 80TTA/TTB: Interest from savings accounts or deposits.
Hence, Up to ₹1.5 lakh can be claimed as a deduction every year from the Gross Total Income — one of the simplest ways to lower taxes legally.
Why Correct GTI Matters
Everything else in your return depends on this single number.
An inaccurate GTI can lead to mismatches with Form 26AS or AIS, delay refunds, or even trigger notices."
For businesses & professionals, it can distort advance-tax calculations too.
That’s why even CAs double-check the GTI figure before filing — it’s the anchor for your entire computation.

Old vs New Regime: Does It Change GTI?
No. The method of computing GTI stays the same in both regimes.
The only difference lies in what happens after you arrive at it.
- Under the old regime, deductions & exemptions apply freely.
- In the new one, most of them are forgone in exchange for lower slab rates.
But either way, you must know your Gross Total Income first — because that’s the foundation for choosing which regime saves you more.
