In India, the Income-tax Act entails the rules and regulations to follow, for computation of tax. The Act establishes different tax slabs for calculating the taxes for a person based on different categories. Every year the slab rates are finalized in the Union Budget. Depending upon the income earned by a person the slab rates vary, and so does the tax.
Tax Slabs
The tax which needs to be paid can be easily computed using an Income Tax Calculator which is freely available online. In order to use it, there are a few details which you need to provide. These include exemption details, income details, details of deduction under income tax Form 16 A among other to get the desired details from the calculator.

The slabs for income tax have been divided based on the type of person, age, and category. Individuals and HUF (Hindu Undivided Families) have been divided into the following three categories –
1. Residents as well as non-residents below the age of 60 years
2. Senior citizen resident equal to or between the age of 60 years and 80 years
3. Super senior citizen resident above 80 years of age
