How to Calculate Income Tax?

Income Tax Calculation your Salary: An Example

Let us try to understand how to calculate Income Tax on your salary. 

Suppose an employee A with a company earns a basic salary of Rs 37,500 per month.

The salary for A in the financial year 2019-2020, will be Rs 37,500 X 12= Rs 450,000. 

Let us now consider the various components of the salary of A.

Suppose A’s salary also includes House Rent Allowance (HRA) of Rs 20,000 per month.

HRA =Rs 2.4 Lakh per year.

A stays in Hyderabad and pays rent of Rs 15,000 per month.

Total Rent = 15,000 X 12= Rs 1.80 Lakh per year.

There is also a special allowance or some incentive component of Rs 10,000 per month.

Special Allowance= Rs 10,000 X 12= Rs 1.2 Lakh per year.

A also has an EPF component that is deducted from his salary per month, which is 12% of his basic salary every month,

EPF =Rs (37,500 X 0.12) = Rs 4,500 per month, or 4500 X 12=Rs 54,000 p.a.

Taxable Income from Salary

As per the HRA computation method, we have to take the lowest of these 3 values for tax purposes:

  • 50% of annual basic salary = Rs (4.5 Lakh X 0.5) = Rs 2.25 Lakh
  • HRA received on an annual basis = Rs 2.4 Lakh
  • Rent that is paid in excess of 10% of annual basic salary = Rs (1.8 Lakh - (0.1 X 4.5 Lakh)) = Rs 1.35 Lakh

Therefore, the Total taxable HRA = Rs 2.4 Lakh – Rs 1.35 Lakh = Rs 1.05 Lakh for A. 

Now, Gross Income from Salary= Basic + HRA +Special Allowance

So, the Gross Income from Salary= Rs 4.5 Lakh + Rs 2.4 Lakh + Rs 1.2 Lakh = 8.10 Lakh

Total exemptions= Taxable HRA + Standard Deduction, I.e., Rs 1.35 Lakh + Rs 50,000

Now, Taxable Income from Salary= Gross Income from salary- Total taxable amount.

I.e. Total taxable amount= Rs 50, 000

(In the Interim Budget of 2019, Standard Deduction or exemption became Rs 50,000)

Taxable Income from Salary= Rs 4.5 Lakh + Rs 1.05 Lakh + Rs 1.02 Lakh – Rs 50,000= Rs 6.25 Lakh

Now, let A invest in Public Provident Fund i.e., PPF and Equity Linked Savings Scheme (ELSS) during the financial year 2019-20. These investments are for Rs 50,000 for PPF and Rs 15,000 towards ELSS. 

Total deductions= Rs 50,000 +Rs s15,000+ EPF contribution deducted by employer i.e. Rs 54,000 (Maximum limit is Rs 1.5 Lakh)

I.e. Rs 50,000 + Rs 15,000+ Rs 54,000= Rs 119,000

Now Gross Taxable Income = Taxable Income from Salary –Total deductions.

In A’s case, this amounts to= Rs 6.25 Lakh – Rs 1.19 Lakh = Rs 5.06 Lakh

  • Q: Is filing for income tax returns mandatory?

    Ans: If your annual income is below the exemption limit, then you need not file income tax returns. However, if you have an income that falls below the taxable limit, but has a PAN (Permanent Account Number) card; it is better to file your ITR with a NIL or zero return. Individuals who have income less than Rs 2.5 Lakh and still want to claim an income tax refund can only do so by filing an ITR. 

    Otherwise, it is mandatory to file income tax returns. Even if you are an Indian resident with investments or property outside India, you need to file income tax returns. This is applicable even if your overall income falls below the prescribed tax limit. You will also have to file your tax returns if you want to claim refunds on any advance taxes that you may have paid in earlier.

  • Q: When do I have to pay taxes on my income?

    Ans: The taxes on the income of an individual can be finalized and paid only on the completion of the previous year. However, our Income-tax Act provides the option to pay taxes in advance during the earning year or before the completion of the previous year. It is also known as Pay as you earn a concept. This is to enable a regular flow of funds and for a straightforward process of collection of taxes.
  • Q: What is the maximum limit for non-taxable income?

    Ans: Income up to Rs 2.5 Lakh is exempt from taxes. Under Section 87A of the Indian Income Tax Act, an individual gets a full rebate on tax if his income is less than Rs 5 Lakh.
  • Q: Does the income tax calculator provide a TDS feature?

    Ans: No, the income tax calculator does not provide this feature. It does not include the Tax Deducted at Source or the TDS. It just calculates your tax liability for the assessment year.
  • Q: Is there any difference between exemption and deductions while computing taxes?

    Ans: An Income tax exemption is provided on specific sources of income and not on the total income. On the other hand, income tax deductions can be claimed on the total gross income. You can claim Income tax deductions on certain specified investments and expenditures. This is the amount of money that is reduced from your total taxable income. Sections 80C to Sec 80U of the Income Tax Act, 1961, deal with the various deductions available to taxpayers.
