Tax Rebate under Section 87A

Tax Rebate under Section 87A is a type of rebate you get when your taxable income is below Rs. 5 Lacs in financial year.

For Old Tax regime, your taxable income will be calculated by subtracting your total investment deductions from gross salary. This will give you the taxable income on which your income tax will be calculated.

If this taxable income is less than Rs. 5 Lacs in a financial year, you will get maximum tax rebate of Rs. 12,500 according to which your actual income tax will be Rs. 0.

On the other hand, with new tax regime, since you don’t get any deduction options to be claimed, your gross income is considered as taxable income on which income tax will be calculated.

If this gross income is below Rs. 5 Lacs in financial year, than you are eligible to claim Tax Rebate under Section 87A.
