Section 14 of the Act provides that for the purpose of charge of Income tax and computation of total income, all incomes shall be classified under following five heads of income
(i) Income under the head “Salaries”.
(ii) Income under the head “House Property”.
(iii) Income under the head “Profits and gains of Business or Profession”.
(iv) Income under the head “Capital Gains”.
(v) Income under the head “Other Sources”.
After aggregating income under various heads (Duly applying clubbing provisions), losses are adjusted and the resultant figure is called “Gross Total Income” (GTI). ‘Gross Total Income’ may also be understood as the total income of an assessee before making any deduction under chapter VIA i.e., undersection 80C to 80U of the Act. Thus,
G. T. I. = Salary Income + House Property Income + Business or Profession Income+ Capital Gains + Other Sources Income + Clubbing of Income - Set-off of Losses
Total Income [Section 2(45)]
‘Total income’ means the total amount of income referred to in section 5, computed in the manner laid down in this Act. In other words, ‘Total Income’ means income remaining after allowing deductions under Chapter VIA (i.e., U/s 80C to 80U) from Gross Total Income. It is important to note that income tax is charged on total income at prescribed rate(s).
