For the year 2020, the Financial Minister declared the union budget on 1st February 2020. For a salaried employee, their salary slip comprises of various components of their salary.

The total salary is a summation of basic salary, HRA, transportation allowance, special allowance, and any other kind of allowances. The Income Tax Act offers various exempt from salary like rent allowance, leave travel allowance, etc.

Further, the government has also incorporated a standard deduction of Rs. 50,000 from all employees irrespective of their total income. It is important to note, that if someone opts for a new tax regime then various exemptions will not be applicable to them.

The new Union Budget has launched an additional tax regime scheme where individuals can opt to forgo some exemptions and deductions. This simplified regime has different tax slabs and co-exist with the traditional regime.

An individual can choose from both the regimes whichever suits their requirements better. Below are the new tax slabs and their corresponding tax rates:

How to calculate income tax?

This process becomes extremely easy by using an income tax calculator. Here is a basic understanding of how does income tax calculator works.

Case 1: It is very easy to calculate the taxable income. Taxable income does not mean the income on which taxes are paid, this is inclusive of the deductions and exemptions available.

For example: Mr. Mehta has a net taxable income of Rs. 15 lakh after removing deductions and exemptions. Then he will pay the following tax:

Income Tax Slab Tax Slab Rate Tax Paid
Up to Rs. 2.5 lakh Nil Nil
Between Rs. 2.5 lakh – Rs. 5 lakh 5% Rs. 12,500


Between Rs. 5 lakh – Rs. 7.5 lakh 10% Rs. 25,000
Between Rs. 7.5 lakh – Rs. 10 lakh 15% Rs. 37,500
Between Rs. 10 lakh – Rs. 12.5 lakh 20% Rs. 50,000
Between Rs. 12.5 lakh – Rs. 15 lakh 25% Rs. 62,500

So, Mr. Mehta will pay tax worth Rs. 1,87,500 on the net taxable income of Rs. 15 lakh.

Case 2: If the net taxable income is not known. Let’s say Mr. Mehta has a basic salary of Rs. 60,000 per month, HRA of Rs 20,000, Conveyance allowance Rs. 4,000 and any special allowance Rs. 2,000 with travel allowance worth Rs. 10,000 per year.

Total basic salary = 60,000*12 = Rs. 7,20,000

Total HRA = 20,000*12 = Rs. 2,40,000 (will not be taxable)

Total travel allowance = 4,000*12 = Rs. 48,000 (it is capped at Rs. 19,200)

Total special allowance = 2,000*12 = Rs. 24,000

Gross salary = basic + HRA + travel + special + travel/leave allowance = 7,20,000 + 2,40,000 + 48,000 + 24,000 +10,000 = Rs. 10,42,000

Let’s assume a person claims the yearly travel/leave allowance with air tickets worth Rs. 8,000.

Total gross taxable income = basic + HRA + travel + special + travel/leave allowance = Rs. 7,20,000 + Rs. 0 + Rs. 28,800 + Rs. 24,000 + Rs. 8,000

Total gross taxable income = 7,80,800

Any investments done will be further deducted from this sum.
