Navigating the realm of income tax involves understanding two fundamental concepts - Gross Total Income (GTI) and deductions under various sections. GTI serves as the canvas upon which an individual's or entity's entire income is painted, while deductions under Section 80 of the Income Tax Act weave a tapestry of opportunities for taxpayers to reduce their taxable income. In this blog, we will unravel the meaning of Gross Total Income and delve into the significant deductions available under Sections 80C, 80CCC, 80CCD, 80D, 80E, 80G, 80GG, 80QQB, and 80U.


Understanding GTI is foundational to effective tax planning and compliance. It not only provides a comprehensive overview of an individual's or business's financial health but also serves as the baseline for computing the tax liability. GTI forms the canvas on which deductions are applied, shaping the final portrait of taxable income.


Gross Total Income is the aggregate of all incomes earned by an individual or a business before any deductions or exemptions. It encompasses various sources, including salary, business profits, capital gains, house property income, and income from other sources. GTI serves as the starting point for calculating the taxable income, forming the basis upon which deductions are applied.

The components of GTI include, but are not limited to:

  • Salary Components –

Basic salary, allowances, bonuses, perks, and other forms of remuneration earned through employment.

  • Business Income –

Profits generated from business activities after accounting for allowable business expenses.

  • Capital Gains –

Profits realized from the sale of capital assets, such as real estate, stocks, or mutual funds.

  • House Property Income –

Rental income from owned properties after adjusting for municipal taxes and standard deductions.

  • Income from other source –

Miscellaneous income, including interest income, dividends, gifts, lottery winnings, and other sources of revenue.


Tax deductions are the sum of money that can be reduced from the total taxable income. To get the net income of a taxpayer, the deduction amount is first included in the gross total income and then subtracted from it. It is a kind of concession received by the taxpayers from the income tax department.
