Taxation is one of the most important areas in the UGC NET Commerce and Management syllabus. A clear understanding of income classification and deduction rules is essential not only for examination purposes but also for practical application in financial planning and tax filing. In this blog, we will explore the basics of income computation under the Income Tax Act, focusing on income classification, deductions, and their role in determining taxable income.
1. Income Classification under the Income Tax Act
The Income Tax Act, 1961 divides income into five
heads. Each head has its own set of rules for computation:
2. Computation of Gross Total Income (GTI)
Gross Total Income is computed by adding up income
from all the above heads:
GTI = Salary Income + House Property Income + Business/Profession Income + Capital Gains + Other Sources
3. Deductions under Chapter VI-A
After calculating GTI, deductions are allowed
under Sections 80C to 80U, reducing the taxable income. Some
important deductions are:
4. Computation of Total Taxable Income
The formula for arriving at Taxable Income is:
Gross Total Income –Deductions under Chapter VI−A = Total Income
This Total Income is then charged to
tax as per the applicable slab rates.
5. Example of Tax Computation
Suppose an individual has the following incomes:
Step 1: Compute Gross Total Income
Step 2: Deductions
Step 3: Taxable Income
GTI – Deductions = ₹9,10,000 – ₹1,85,000 = ₹7,25,000
Tax is then computed on ₹7,25,000 according to the
slab rates.
Conclusion
Tax computation requires a systematic approach: first
classify income under the correct head, then aggregate it to determine Gross
Total Income, and finally reduce it with eligible deductions. For UGC NET
aspirants, understanding these steps is crucial, as questions often test both
theoretical concepts and problem-solving abilities in taxation.
