Definition of Taxable Income
Taxable income refers to the portion of an individual’s or business’s total income that is subject to taxation by the government after applying exemptions, deductions, and adjustments as allowed under the tax laws. It is the base amount on which tax liability is calculated.
Meaning of Taxable Income in Detail
Taxable income is the foundation of any country’s income tax system. While individuals earn income from salaries, businesses generate profits, and investors earn returns on capital – not all income is taxed. Governments allow exemptions, deductions, and adjustments to encourage savings, investment, and essential expenses (such as medical insurance, retirement contributions, or business expenses).
For example, in India, the Income Tax Act, 1961, specifies how gross income should be computed, what exemptions are available, and how deductions under sections like 80C, 80D, or 24(b) reduce taxable income. In the United States, the Internal Revenue Code defines similar rules.
Thus, taxable income is not simply “total income earned” but “total income minus allowed deductions and exemptions.”
Components of Taxable Income
Taxable income can include:
-
Salary or Wages (basic pay, allowances, bonuses, commissions)
-
Business or Professional Income (profits after deducting business expenses)
-
Capital Gains (from sale of property, shares, or investments)
-
House Property Income (rental income, adjusted for interest deductions)
-
Other Sources (interest, dividends, lottery winnings, etc.)
Formula for Taxable Income
The general formula is:
Taxable Income = Gross Total Income – (Exemptions + Deductions + Adjustments)
Where:
-
Gross Total Income = Sum of income from all sources (salary, business, capital gains, etc.)
-
Exemptions = Income specifically excluded (e.g., agricultural income in India, certain municipal bonds in the U.S.)
-
Deductions = Allowed deductions under tax law (e.g., retirement contributions, Section 80C deductions, HRA, insurance premiums, etc.)
-
Adjustments = Loss carryforwards, depreciation, standard deductions, etc.
Example Calculation of Taxable Income
Suppose Mr. Raj earns the following in FY 2024-25:
-
Salary Income: ₹10,00,000
-
Interest on Savings: ₹50,000
-
Rental Income: ₹2,00,000
-
Total Gross Income = ₹12,50,000
Deductions allowed:
-
Standard Deduction: ₹50,000
-
Section 80C Investments: ₹1,50,000
-
Section 80D (Medical Insurance): ₹25,000
Taxable Income = 12,50,000 – (50,000 + 1,50,000 + 25,000) = ₹10,25,000
This ₹10,25,000 becomes the base on which income tax rates (slab rates) are applied.
Journal Entry for Taxable Income (Accounting Treatment)
While taxable income itself is a tax computation concept, businesses record tax liabilities in their books based on taxable profit.
Example:
A company reports net profit before tax of ₹20,00,000. After allowable deductions, taxable income is ₹18,00,000. Tax @ 30% = ₹5,40,000.

Detailed Illustration of Taxable Income Calculation
XYZ Pvt Ltd (FY 2024-25):
-
Revenue from Operations: ₹80,00,000
-
Other Income: ₹5,00,000
-
Total Revenue: ₹85,00,000
Expenses:
-
Salaries: ₹20,00,000
-
Rent: ₹5,00,000
-
Depreciation: ₹3,00,000
-
Other Expenses: ₹12,00,000
-
Total Expenses: ₹40,00,000
Profit Before Tax (PBT) = ₹45,00,000
Adjustments under Income Tax Act:
-
Add Disallowed Expenses: ₹1,00,000
-
Less: Additional Depreciation Allowed: ₹50,000
Taxable Income = ₹45,00,000 + ₹1,00,000 – ₹50,000 = ₹45,50,000
If corporate tax rate = 25% → Tax = ₹11,37,500.
