Gross Total Income vs Total Income – Key Differences
Your salary is ₹10 lakh but Total Income might be just ₹8.5 lakh! The difference? Deductions. Let's understand GTI vs TI.
Quick Definitions
Gross Total Income (GTI) = Sum of income from all 5 heads (before deductions)
Total Income (TI) = GTI - Deductions under Chapter VI-A (Sections 80C to 80U)
Formula: Total Income = GTI - Chapter VI-A Deductions
The Flow
Five Income Heads
All income classified under:
- Salary (Sections 15-17)
- House Property (Sections 22-27)
- Profits & Gains of Business or Profession (Sections 28-44)
- Capital Gains (Sections 45-55)
- Income from Other Sources (Sections 56-59)
Any income not falling in above 4 → Automatically "Other Sources"

Practical Example
Mr. Sharma (FY 2023-24):
Income Details:
- Salary (after ₹50k standard deduction): ₹8,50,000
- House Property (rental income): ₹1,00,000
- Interest from FD: ₹40,000
Investments:
- PPF: ₹1,50,000
- NPS: ₹50,000
- Health insurance (family): ₹20,000
- Education loan interest: ₹30,000
Computation:
Mr. Sharma - GTI to Total Income
| Income from Salary | ₹8,50,000 |
| Add: Income from House Property | ₹1,00,000 |
| Add: Income from Other Sources (FD interest) | ₹40,000 |
| Gross Total Income (GTI) | ₹9,90,000 |
| Less: Less: Section 80C (PPF) | (₹1,50,000) |
| Less: Less: Section 80CCD(1B) (NPS) | (₹50,000) |
| Less: Less: Section 80D (Health insurance) | (₹20,000) |
| Less: Less: Section 80E (Education loan interest) | (₹30,000) |
| Total Income | ₹7,40,000 |
Tax calculation:
- Total Income: ₹7,40,000
- Rebate under Section 87A (if total income ≤ ₹7L in new regime): NIL tax
- Otherwise: Tax as per slabs
Savings from deductions: ₹9.9L - ₹7.4L = ₹2.5L reduced from taxable income!
Key Differences
Gross Total Income (GTI)
- Sum of income from 5 heads
- Before any Chapter VI-A deductions
- Higher amount
- Calculated first
Total Income (TI)
- GTI minus deductions
- After Chapter VI-A deductions
- Lower amount
- Tax applied on this
Which deductions from GTI, which from Total Income?
From individual heads (before GTI):
- Standard deduction ₹50k (from salary)
- 30% standard (from house property)
- Professional tax (from salary)
- Business expenses (from business)
From GTI (Chapter VI-A):
- Section 80C to 80U
- Investment-linked deductions
- Insurance, donations, etc.
Example 2: With House Property Loss
Mrs. Kapoor:
Income:
- Salary: ₹6,00,000
- House Property: (₹2,00,000) - Loss due to ₹2L interest on self-occupied house
- Bank Interest: ₹30,000
Deductions:
- 80C: ₹1,50,000
Computation:
Mrs. Kapoor - With House Property Loss
| Income from Salary | ₹6,00,000 |
| Less: Loss from House Property (set off against salary) | (₹2,00,000) |
| Add: Income from Other Sources | ₹30,000 |
| Gross Total Income | ₹4,30,000 |
| Less: Less: Section 80C | (₹1,50,000) |
| Total Income | ₹2,80,000 |
Tax: NIL (below ₹3 lakh in new regime OR ₹2.5L in old regime)
Note: Loss from house property reduces GTI itself!
Set-Off & Carry Forward Rules
Inter-head set-off (before arriving at GTI):
- Loss from one head can be set off against other head's income
Example:
- Salary: ₹10L
- House Property Loss: (₹2L)
- GTI: ₹8L (loss already adjusted)
Intra-head set-off:
- Long-term capital loss can only be set off against long-term capital gain
- Short-term capital loss can be set off against any capital gain
Important Points
1. Deductions only if offered:
- Can't claim 80C deduction if income itself below taxable limit (no benefit)
2. Deduction ≠ Tax saving:
- ₹1.5L deduction under 80C
- Tax saved = ₹1.5L × your tax rate
- If 20% bracket: Save ₹30,000 tax
- If 30% bracket: Save ₹45,000 tax
3. New tax regime:
- Most Chapter VI-A deductions NOT allowed
- Lower tax rates compensate
- Only 80CCD(2) (employer NPS), 80JJA allowed
Summary
- GTI: Sum of income from 5 heads (Salary + House + Business + Capital Gains + Other Sources)
- Total Income: GTI - Chapter VI-A deductions (80C to 80U)
- Tax applied on: Total Income (not GTI)
- Major deductions: 80C (₹1.5L), 80CCD(1B) (₹50k), 80D (₹25-100k), 80E (no limit), 80G (donations)
- Loss adjustment: House property/business loss reduces GTI directly
- New regime: Most deductions not allowed, but lower tax rates
