Before we understand the concept of income tax, here are few terms which you should know as they help in tax calculations –

  • Financial year Financial year is the year in which you earn an income. It starts from April and ends on March of the next year. For instance, the current financial year is 2019-20. It started from 1st April 2019 and would end on 31st March 2020. Income that is within one financial year is taxed in the next financial year which is called the assessment year.
  • Assessment year Assessment year is the year in which your tax liability is calculated. It follows the financial year and calculates the liability on the income generated in that financial year. So, for the financial year 2019-20, the assessment year would be 2020-21 which would start from 1st April 2020 and end on 31st March 2021. Incomes earned up to 31st March, 2020 would be taxed in the financial year 2020-21 which would be called the assessment year.
  • Assessee The individual whose income is taxed is called an assessee in income tax parlance. It can be an individual like you, a company or a partnership firm, LLP etc.
    As per the rules stated in the Income Tax Act, 1961, there are five heads of income under which all your income can be categorised and taxed as per the provisions. These heads of income are as follows –
    1. Income from salary This head of income is relevant for salaried employees who earn a salary from their employer. The salary that they earn and its various components are classified under this income head.
    2. Income from business/profession Any profits/ gains earned by carrying out a business activity is classified under this head of income. Like earning from running a small shop or proprietorship business etc. Further, earning of individuals who are engaged in a profession like Doctors, Chartered Accountants, Engineers is also classified under this head of income.
    3. Income from house property If you own a house and the house has been let out from which you earn a rental income, such an income would be recorded under this head of income
    4. Income from capital gains Capital gains are said to occur when there has been a sale of a capital asset and you have earned a profit from such sale. Capital assets mean a house property, flat, land, jewellery, mutual funds, shares etc.
    5. Income from other sources This head of income includes incomes which do not fall under any of the above-mentioned categories. For instance, interest income from deposits or bank accounts, dividends received, winnings from lotteries or games, etc.

Income Tax Slabs


Once the income is categorised under the above-mentioned heads, the gross taxable income is arrived at. From this income, tax-free deductions and exemptions are deducted to arrive at the net taxable income. The net taxable income is, then, subject to the calculation of tax liability. There are income tax slabs which specify the tax payable on the net taxable income. In India, income tax is charged on a progressive basis meaning as the income increases, so does the tax liability.
The income tax slab rates can be changed by the Government of India if felt necessary. Currently, the income tax slab rates are as follows –

Income tax slab for individuals aged up to 60 years (Applicable for FY 2019-20)

Income tax payable by NRIs

If you are a “resident individual”, you would be taxed on your global income which means the income earned from India as well as any foreign income that you might have earned would be taxable. In case of Non-Resident Indians (NRI’s), however, income tax is charged only on the portion of income which they earn in India. Foreign income would be taxed in the country in which they live.
So, understand the concept of income tax and how it is calculated so that you can calculate your tax liability and file your income tax returns every year without any ambiguity.
