When it comes to income tax, many taxpayers are confused about what exactly qualifies as taxable income. You might earn salary, rent, interest, or profit from trading—but does all of it get taxed? Not really.
Let’s break it down: Taxable Income is the portion of your total income subject to tax under the Income Tax Act. The government doesn’t tax your full income—they allow certain deductions & exemptions. What remains after these benefits is your taxable income, and that’s what your tax liability is based on.
What is Taxable Income?
Taxable income is the amount from gross income on which the income tax is paid. In simple words, it’s your net income after exemptions and deductions.
For example, if you earn ₹10 lakh in a year but claim ₹2 lakh in deductions (like investments, insurance, etc.), then your taxable income is ₹8 lakh.
It is calculated after the computation of gross total income & taxable income, which involves summing up all income heads and subtracting deductions allowed under Chapter VI-A.
What is Gross Total Income?
Before arriving at taxable income, we must understand gross total income (GTI). This is the total of all your income from the five heads:
- Salary
- House Property
- Profits and Gains from Business or Profession
- Capital Gains
- Other Sources (interest, lottery, etc.)
So, any income you earn during the tax year across these heads is first added up to compute your GTI."
How to Calculate Taxable Income?
Here’s a quick step-by-step breakdown:
Step 1: Compute Gross Total Income
Add income from all heads:
- Salary (after standard deduction)
- Rental income (less municipal taxes & standard deduction)
- Business income (net profit)
- Capital gains (STCG/LTCG)
- Other income (FD interest, savings interest, dividends)
Step 2: Deduct Deductions under Chapter VI-A
These include:
- Section 80C – LIC, PPF, ELSS, home loan principal (up to ₹1.5 lakh)
- Section 80D – Medical insurance premium
- Section 80TTA/TTB – Interest on savings for individuals/senior citizens
- Section 80E, 80G, 80GG, etc.
Step 3: Arrive at Taxable Income
Taxable Income = Gross Total Income – Deductions
Now apply the tax rates (based on slab or new regime) to this amount."

Why is Knowing Your Taxable Income Important?
Understanding taxable income helps you:
- Plan your taxes better
- Choose the right tax regime (old vs new)
- Avoid overpaying taxes
- File your ITR accurately
- Reduce the chances of scrutiny or notices
Example of Taxable Income Calculation
Let’s say:
- Salary: ₹9,00,000
- Interest from FDs: ₹50,000
- Rental Income: ₹1,20,000
Gross Total Income = ₹10,70,000
Deductions:
- Section 80C (LIC, PPF): ₹1,50,000
- Section 80D (Mediclaim): ₹25,000
- Section 80TTA (Savings Interest): ₹10,000
Total Deductions = ₹1,85,000
Taxable Income = ₹10,70,000 – ₹1,85,000 = ₹8,85,000
You now pay tax only on ₹8.85 lakh.
Old vs New Regime: Impact on Taxable Income
Under the old regime, you can claim all deductions to reduce taxable income.
Under the new regime, most exemptions & deductions are not available, but the tax slabs are lower.
So, the same gross total income may lead to different taxable income amounts, depending on the regime chosen.
Choose wisely based on your investment and deduction claims.
Key Points to Remember
- Taxable income is not equal to total income earned
- Use deductions smartly to bring down taxable income
- Slab rates apply only to taxable income, not gross income
- For salaried people, the standard deduction of ₹50,000 is automatic
- TDS may be deducted from gross income, but tax is paid only on net taxable income

Common Mistakes in Declaring Taxable Income
- Forgetting to include income from previous jobs
- Missing out on bank interest income
- Claiming ineligible deductions
- Not comparing tax regimes before filing
- Filing ITR with wrong income calculations
Deadline to File Your ITR
For individuals & salaried employees (non-audit cases), the due date is usually 31st July of the assessment year, which has been changed by CBDT to 15th September. Filing after this attracts penalties under Section 234F.
So, calculate your taxable income correctly and file your ITR well before the deadline.

With a clear understanding of the computation of gross total income and taxable income, you can make smarter financial decisions & even reduce your tax outgo.
