Process of Income-tax calculation for the Salaried Persons for F.Y. 2020-21 As per Budget 2020
Income from salary is the sum of Basic salary + HRA + Special Allowance + Transport Allowance + any other allowance. Some components of your salary are exempt from tax, such as telephone bills reimbursement, leave travel allowance. If you receive HRA and live on rent, you can claim an exemption on HRA. Calculate the exempt portion of HRA, by using this HRA Calculator. 

On top of these exemptions, a standard deduction of Rs 40,000 was introduced in budget 2018. This has been increased to Rs 50,000 in budget 2019.
In case you opt for the new tax regime, these exemptions will not be available to you.
Let's understand income tax calculation under the current tax slabs and new tax slabs (optional) by way of an example. Mira receives a Basic Salary of Rs 1,00,000 per month. HRA of Rs 50,000. Special Allowance of Rs 21,000 per month. LTA of Rs 20,000 annually. Mira pays a rent of Rs 40,000 and lives in Delhi.
