Introduction 

If you will be filing ITR for the first time in 2020 then you need to know your total taxable income, followed by the computation of income tax as per the applicable tax slab. While calculating income tax manually might appear daunting, it isn’t as complicated if you thoroughly understand the computation process.

Every individual under 60 years of age with an annual income of more than Rs. 2.5 lakhs must file Income Tax Return (ITR) as per the Income Tax Act. For seniors between 60 and 80 years, this limit is above Rs. 3 lakhs, and for super seniors above 80 years, it is above Rs. 5 lakhs. Even people falling under the nil tax bracket are advised to file ITR.

What is Taxable Income? Taxable income means the income which is chargeable to income tax, and it is calculated to decide how much tax an individual or a company owes to the government in a particular tax year. It is generally described as the gross total income or total income. To arrive at the total income, you have to consider any deductions or exemptions allowed in that tax year.

Taxable income includes salaries, pensions, capital gains, rental income, business income, investment income, and unearned income.

How to Calculate Income Tax? Income tax can be estimated using an online income tax calculator. However, in the absence of the same, you can also calculate income tax liability manually. Here is how.

We can attempt to calculate income tax by using an example of Ms Menon whose earnings include a basic salary of Rs. 37,500 per month (i.e., Rs. 4.5 lakh per annum) in the financial year 2019-2020.

    Her salary also includes House Rent Allowance (HRA) of Rs. 20,000 per month or Rs. 2.4 lakhs per year.

    The Leave Travel Allowance (LTA) is Rs. 15,000 on an annual basis.

    There is also a special allowance component of Rs. 10,000 per month (i.e., Rs. 1.2 lakh per year).

    Ms Menon lives in Kerala and pays rent of Rs. 15,000 per month, which amounts to Rs. 1.80 lakh per year.

    There is also an EPF component (Ms Menon’s share) that is deducted from her salary per month. This is equivalent to 12% of her basic salary every month, i.e., Rs. (37,500 * 0.12) = Rs. 4,500. On an annual scale, this will amount to Rs. 54,000.

Step 1: Calculating Taxable HRA The first step is to identify the HRA chargeable to tax. Ms Menon calculates the taxable component of her HRA manually. Here is how.

The lowest value among the following will be exempt from tax:

    50% of Ms Menon’s annual basic salary = Rs. (4.5 lakh * 0.5) = Rs. 2.25 lakh

    HRA received on an annual basis = Rs. 2.4 lakh

    Rent that is paid more than 10% of annual basic salary = Rs. (1.8 lakh - (0.1 * 4.5 lakh)) = Rs. 1.35 lakh

Therefore, the total taxable HRA = Rs. 2.4 lakh – Rs. 1.35 lakh = Rs. 1.05 lakh

Step 2: Calculating Taxable Income from Salary The annual gross income from her salary is outlined in the table below:

Component Total Amount Exemption Taxable Amount Basic Salary Rs. 4.5 lakh - Rs. 4.5 lakh (A) HRA Rs. 2.4 lakh Rs.1.35 lakh Rs. 1.05 lakh (B) Special Allowance Rs. 1.2 lakh - Rs. 1.2 lakh (C) LTA Rs. 15,000 Rs.10,000 (travel bills submitted) Rs. 5,000 (D) Standard Deduction*   Rs.50,000 (E)   Gross Income from Salary Rs. 8.25 lakh (sum of the above rows in this column)   A + B + C + D - E = Rs. 6.3 lakhs
