Aggregation of income refers to the process of combining different sources of income under various heads to calculate the total taxable income of an individual in a financial year. Under the Income Tax Act, 1961 in India, this is a crucial step to determine the accurate tax liability of an individual. The tax regime in India categorizes income under five main heads, and the aggregation of these ensures that the income is taxed appropriately according to the rules pertaining to each category.
- Heads of Income
The Income Tax Act specifies five primary heads of income under which all earnings must be classified:
- Income from Salaries
- Income from House Property
- Profits and Gains of Business or Profession
- Capital Gains
- Income from Other Sources
Each type of income has its own set of rules for computation and taxation, including permissible deductions and exemptions.
-
Computation of Income Under Each Head
Before aggregation, income under each head must be computed separately:
- Salaries:
Includes wages, pension, allowances, and other benefits.
- House Property:
Calculated as the net annual value minus allowed deductions like municipal taxes and standard deduction.
- Business or Profession:
Net profit after deducting business expenses, depreciation, and other allowable deductions.
- Capital Gains:
Gains arising from the sale of a capital asset, adjusted for indexation and permissible deductions.
- Other Sources:
Includes interest, dividends, lottery winnings, and other miscellaneous income.
-
Set-off and Carry Forward of Losses
While aggregating income, any losses under one head (except salaries) can be set off against income from other heads, according to specific rules. For instance, loss from house property can be set off against salary income. Unabsorbed loss after such set-off can be carried forward to subsequent years to be set off against income under the same head.
-
Aggregation of Income
After computing the income under each head and adjusting for any set-off of losses, all these figures are aggregated. This gives the Gross Total Income (GTI).
-
Deductions Under Chapter VIA
From the Gross Total Income, deductions under various sections of Chapter VIA (Sections 80C to 80U) are allowed. These include deductions for investments in specified savings schemes, insurance premiums, educational expenses, donations to charitable trusts, medical insurance, etc.
-
Calculation of Total Taxable Income
After all deductions are applied, the result is the Total Taxable Income. This figure is used to compute the income tax liability according to the tax rates applicable for the financial year.
-
Clubbing of Income
In cases where the income of another person like a spouse, minor child, etc., needs to be included in the income of the taxpayer (as discussed in earlier explanations), this clubbing is done before the final aggregation.
-
Final Tax Computation
The total income is then subjected to the prevailing tax rates to compute the tax payable. Rebates, relief under Section 89(1), and credit for prepaid taxes (like advance tax and TDS) are accounted for to arrive at the net tax liability or refund.
